Understanding Cialis: A Comprehensive Overview

Cialis, known generically as tadalafil, is a medication primarily prescribed for two conditions: erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). As a phosphodiesterase 5 (PDE5) inhibitor, Cialis works by relaxing blood vessels to increase blood flow to the penis in ED cases. For BPH, it relaxes bladder muscles to improve urinary flow. This versatile drug comes in tablet form and is designed for oral administration.

Cialis Strengths: Available Dosage Options

Cialis tablets are available in four distinct strengths:

  • 2.5 milligrams (mg)
  • 5 mg
  • 10 mg
  • 20 mg

The variety of strengths allows for personalized treatment plans tailored to individual needs and responses to the medication.

Dosage Guidelines for Erectile Dysfunction

When treating erectile dysfunction, Cialis offers two primary dosing strategies: occasional use and daily use.

Occasional Use for ED

For occasional use, patients typically start with a 10 mg tablet taken before sexual activity. Based on efficacy and tolerability, doctors may adjust the dose down to 5 mg or up to 20 mg. It’s crucial to note that Cialis should not be taken more than once daily, and the maximum recommended dosage is 20 mg per day. Exceeding this limit significantly increases the risk of serious side effects.

Daily Use for ED

The daily use regimen for ED typically begins with a 2.5 mg dose taken once daily, regardless of sexual activity timing. If this proves insufficient, the dosage may be increased to 5 mg daily. This approach maintains a consistent level of the drug in the system, potentially offering more spontaneity in sexual activity.

Treating Benign Prostatic Hyperplasia with Cialis

For BPH symptoms, the standard Cialis dosage is 5 mg once daily for up to 26 weeks. Consistency in timing is key, with patients advised to take their dose at approximately the same time each day.

Combination Therapy: Addressing ED and BPH Simultaneously

In cases where patients require treatment for both ED and BPH, Cialis offers a dual-action solution. The recommended dosage for this combined treatment is 5 mg once daily, taken at a consistent time. This regimen eliminates the need for additional occasional doses for ED.

Dosage Adjustments for Special Populations

Patients with kidney or liver issues may require dosage adjustments. In these cases, doctors often prescribe lower doses to mitigate the risk of side effects. The severity of kidney or liver problems may also influence the choice between daily and occasional dosing for ED treatment.

Maximizing Cialis Effectiveness: Best Practices

To optimize the effects of Cialis, adherence to prescribed dosing is crucial. For daily regimens, taking the medication at the same time each day helps maintain consistent blood levels. Missed or inconsistent doses can significantly reduce the drug’s efficacy.

For occasional use in ED treatment, timing is essential. Taking Cialis about 30 minutes to 2 hours before sexual activity allows for optimal absorption and effectiveness. However, the extended duration of action (up to 36 hours for some individuals) offers flexibility in timing.

Safety Considerations and Potential Side Effects

While Cialis is generally well-tolerated, it’s important to be aware of potential side effects and safety considerations. Common side effects may include headache, back pain, muscle aches, flushing, and nasal congestion. More serious but rare side effects can include sudden vision or hearing loss, and priapism (an erection lasting more than 4 hours).

Are there any interactions with other medications? Cialis can interact with several medications, particularly nitrates used for heart conditions. It’s crucial to inform your healthcare provider about all medications, supplements, and herbal products you’re taking to avoid potentially dangerous interactions.

Long-Term Use of Cialis

Cialis is often prescribed for long-term use, provided it remains safe and effective for the individual. Regular check-ups with a healthcare provider are essential to monitor ongoing efficacy and any potential side effects or changes in health status that might affect treatment.

Lifestyle Factors Affecting Cialis Efficacy

Can lifestyle changes enhance the effectiveness of Cialis? Indeed, certain lifestyle modifications can complement Cialis treatment:

  • Maintaining a healthy diet
  • Regular exercise
  • Stress reduction techniques
  • Limiting alcohol consumption
  • Quitting smoking

These changes can improve overall cardiovascular health, potentially enhancing the effectiveness of Cialis in treating ED and BPH symptoms.

Understanding the Duration of Cialis Effects

How long does Cialis typically last in the system? Cialis is known for its long duration of action, with effects lasting up to 36 hours in some individuals. This extended window has earned it the nickname “the weekend pill.” However, it’s important to note that the duration can vary based on individual factors such as metabolism, age, and overall health.

For daily users, the consistent blood levels of the medication provide a continuous effect, eliminating the need to time doses with sexual activity. This sustained action is particularly beneficial for those seeking more spontaneity in their sexual lives.

Factors Influencing Cialis Absorption and Effectiveness

Several factors can influence how quickly and effectively Cialis works:

  1. Food intake: High-fat meals may delay absorption
  2. Alcohol consumption: Excessive alcohol can interfere with erectile function
  3. Other medications: Some drugs can interact with Cialis, affecting its efficacy
  4. Overall health: Certain health conditions may impact how well Cialis works

Understanding these factors can help patients optimize their treatment regimen and communicate effectively with their healthcare providers about any concerns or adjustments needed.

Comparing Cialis to Other ED Treatments

How does Cialis compare to other ED medications like Viagra or Levitra? While all belong to the same class of drugs (PDE5 inhibitors), Cialis stands out for its longer duration of action. Viagra and Levitra typically last 4-5 hours, while Cialis can work for up to 36 hours. This extended effect allows for more flexibility and spontaneity in sexual activity.

Additionally, the availability of a daily dosing option for Cialis is unique among ED medications, offering a different approach to treatment that some patients may prefer. However, the choice between these medications often comes down to individual response, side effect profiles, and personal preferences.

Cialis for Women: An Emerging Area of Research

Is Cialis effective for women with sexual dysfunction? While Cialis is primarily designed and approved for use in men, some research has explored its potential benefits for women with certain types of sexual dysfunction. However, these studies are limited, and Cialis is not currently FDA-approved for use in women.

Some preliminary research has suggested that Cialis might improve arousal and orgasm in women with sexual arousal disorders, but more extensive studies are needed to establish safety and efficacy. Women experiencing sexual dysfunction should consult with a healthcare provider to discuss appropriate treatment options.

Navigating Insurance Coverage and Cost Considerations

How is Cialis typically covered by insurance? Insurance coverage for Cialis can vary widely depending on the specific plan and the reason for prescription. Many insurance plans cover Cialis for ED treatment, especially if it’s deemed medically necessary. Coverage for BPH treatment is often more consistent across plans.

For those without insurance coverage or facing high out-of-pocket costs, several options are available:

  • Generic tadalafil: Often significantly less expensive than brand-name Cialis
  • Patient assistance programs: Offered by the manufacturer for eligible individuals
  • Pharmacy discount cards: Can provide savings on prescription medications
  • Comparison shopping: Prices can vary significantly between pharmacies

Patients should discuss cost concerns with their healthcare provider, as there may be alternative medications or dosing strategies that could be more affordable while still effectively treating their condition.

Future Developments in Cialis Treatment

What potential advancements are on the horizon for Cialis and similar medications? Research in the field of erectile dysfunction and BPH treatment continues to evolve. Some areas of ongoing investigation include:

  • New formulations: Exploring alternative delivery methods such as topical applications or rapid-dissolve tablets
  • Combination therapies: Investigating the potential benefits of combining Cialis with other medications for enhanced efficacy
  • Personalized medicine approaches: Utilizing genetic testing to predict individual responses to PDE5 inhibitors
  • Extended-release formulations: Developing versions of tadalafil that could provide even longer durations of action

These potential advancements could offer more tailored and effective treatment options for individuals with ED and BPH in the future.

The Psychological Impact of Erectile Dysfunction and Treatment

How does successful ED treatment with Cialis affect psychological well-being? Erectile dysfunction can have significant psychological impacts, including decreased self-esteem, anxiety, and relationship stress. Effective treatment with medications like Cialis often leads to improvements not only in physical sexual function but also in overall quality of life and psychological well-being.

Many patients report increased confidence, reduced anxiety around sexual performance, and improved relationship satisfaction after successful ED treatment. However, it’s important to note that addressing the psychological aspects of ED may require a multifaceted approach, potentially including counseling or therapy in addition to medical treatment.

Cialis in the Context of Overall Men’s Health

How does Cialis fit into a broader men’s health strategy? While Cialis is primarily prescribed for ED and BPH, its use often opens the door to broader discussions about men’s health. ED can be an early warning sign of underlying cardiovascular issues, and BPH is a common concern in aging men.

Healthcare providers often use Cialis prescriptions as an opportunity to address other aspects of men’s health, including:

  • Cardiovascular risk assessment and management
  • Prostate health screening
  • Discussion of lifestyle factors impacting overall health
  • Mental health and relationship counseling when appropriate

This holistic approach to men’s health can lead to earlier detection and treatment of various health issues, potentially improving overall health outcomes beyond just sexual function.

The Role of Partner Communication in Cialis Treatment

How important is partner involvement in ED treatment with Cialis? Open communication with partners plays a crucial role in the success of ED treatment. Partners can provide emotional support, help with medication reminders, and contribute to a positive sexual experience. Involving partners in discussions about treatment options, expectations, and potential side effects can lead to better outcomes and increased relationship satisfaction.

Healthcare providers often encourage couples to approach ED treatment as a team, fostering open dialogue and mutual understanding. This collaborative approach can strengthen relationships and improve the overall effectiveness of Cialis treatment.

Cialis and Lifestyle: Optimizing Treatment Outcomes

What lifestyle changes can enhance the effectiveness of Cialis? While Cialis is effective on its own, certain lifestyle modifications can significantly improve treatment outcomes:

  1. Regular exercise: Improves cardiovascular health and blood flow
  2. Balanced diet: Supports overall health and may improve erectile function
  3. Stress reduction: Chronic stress can interfere with sexual function
  4. Limiting alcohol: Excessive alcohol can counteract the effects of Cialis
  5. Quitting smoking: Smoking negatively impacts blood flow and erectile function
  6. Weight management: Obesity is linked to increased ED risk
  7. Adequate sleep: Poor sleep can affect hormone levels and sexual function

Incorporating these lifestyle changes alongside Cialis treatment can lead to better overall health and potentially more satisfying sexual experiences.

Managing Expectations with Cialis Treatment

What should patients realistically expect from Cialis treatment? While Cialis is highly effective for many patients, it’s important to manage expectations. Cialis does not cure ED or BPH but rather provides symptomatic relief. It also does not protect against sexually transmitted infections or serve as a form of birth control.

Patients should understand that:

  • Cialis may not work immediately and may require several attempts before optimal effects are achieved
  • Sexual stimulation is still necessary for an erection to occur
  • Individual responses to the medication can vary
  • Side effects, while usually mild, can occur and should be reported to a healthcare provider

Setting realistic expectations and maintaining open communication with healthcare providers can lead to more satisfying treatment outcomes and better overall management of ED and BPH symptoms.

Strengths, Form, When to Use, and More

Cialis (tadalafil) is prescribed to treat erectile dysfunction and symptoms of benign prostatic hyperplasia. It comes as a tablet that’s taken as needed or once per day, depending on the condition it’s treating.

Cialis is used in adult males.* It belongs to a group of drugs called phosphodiesterase 5 (PDE5) inhibitors. These drugs treat erectile dysfunction (ED) by relaxing blood vessels to increase blood flow into the penis. For symptoms of benign prostatic hyperplasia (BPH), they relax the bladder muscles, allowing urine to flow more easily.

This article describes the dosages of Cialis, including its form, strengths, and how to take the drug. To learn more about Cialis, see this in-depth article.

Note: This article covers typical dosages of Cialis, which are provided by the drug’s manufacturer. But when using Cialis, always take the dosage that your doctor prescribes.

* In this article, we use the term “male” to refer to someone’s sex assigned at birth. For information about the difference between sex and gender, see this article.

Get answers to common questions about the dosage of Cialis.

What form does Cialis come in?

Cialis comes as a tablet that you take by mouth.

Available strengths of Cialis (2.5 mg, 5 mg, 10 mg, 20 mg)

Cialis tablets come in four strengths: 2.5 milligrams (mg), 5 mg, 10 mg, and 20 mg.

What are the typical dosages of Cialis?

Typically, your doctor will start you on a low dosage. Then they’ll adjust your dosage over time to reach the right amount for you. Your doctor will ultimately prescribe the smallest dosage that provides the desired effect.

If you have certain kidney or liver problems, your doctor may prescribe a low dosage for you. This is because the usual dosage may increase the risk of side effects with your condition.

The information below describes the usual dosage recommendations for Cialis. But be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.

Dosage for erectile dysfunction (ED)

There are two dosage options when Cialis is used to treat ED: dosage for occasional use and for daily use.

Occasional use for ED

With occasional use, you’ll take Cialis only as needed. You’ll likely take one 10-mg tablet before having sex.

Depending on how well the 10-mg dose works for your ED, your doctor may adjust your dose. It may be decreased to 5 mg or increased to 20 mg. You’ll continue to take it only as needed before sex.

You should not take Cialis more than once per day. You also should not take more than the recommended maximum dosage of Cialis, which is 20 mg per day. Taking higher dosages of Cialis than this, such as 40 mg per day, raises your risk for serious side effects. Examples of these side effects include very low blood pressure and priapism (a painful erection lasting 4 hours or longer).

Daily use for ED

With daily use, you’ll take one dose of Cialis per day. You don’t need to time your dose to be taken before having sex. You should take it around the same time each day.

For daily use of Cialis for ED, the usual starting dosage is 2.5 mg per day. If this dosage isn’t effective for you, your doctor may increase your dosage to 5 mg per day.

Dosage for benign prostatic hyperplasia (BPH)

The usual dosage of Cialis for BPH symptoms is 5 mg once per day for up to 26 weeks. You should take your dose around the same time each day.

Dosage for ED and BPH

If your doctor prescribes Cialis to treat ED along with BPH symptoms, you’ll take Cialis once per day.

For this use, the usual dosage is 5 mg per day. You should not take any additional doses of Cialis for occasional use before sex.

You don’t need to time your dose to be taken before having sex. You should take it around the same time each day.

Is Cialis used long term?

Yes, Cialis is typically used as a long-term treatment. If you and your doctor determine that it’s safe and effective for you, it’s likely that you’ll use Cialis long term.

Dosage adjustments

If you have certain kidney or liver problems, your doctor may prescribe a lower dosage of Cialis for you. This is because, with your condition, the usual dosage may raise your risk for side effects from the drug.

Depending on how severe your kidney or liver problems are, your doctor may recommend occasional dosing instead of daily dosing to treat ED.

How can I get the maximum effect from Cialis?

To get the maximum effect from Cialis, take it exactly as prescribed.

If you’re using once-daily Cialis for either erectile dysfunction (ED) or benign prostatic hyperplasia (BPH), take your dose around the same time each day. This helps keep a consistent amount of the drug in your body to provide the maximum effect. If you forget to take doses, skip doses, or take doses late, the medication won’t work as well.

If you’re prescribed occasional (as needed) Cialis for ED, it’s best to take your dose at least 2 hours before having sex. This is because it takes an average of 2 hours for the drug to reach its highest level in your body.

Because this is an average, you may notice better effects if you have sex a little sooner or a little later than this 2-hour timeframe. In studies, Cialis improved erectile function as soon as 30 minutes to as long as 36 hours after a dose was taken. As long as you do not take more than the maximum daily dose, you can experiment with how long you wait to have sex after taking a dose.

If you have other questions about how to get the most from Cialis, talk with your doctor or pharmacist.

If I take 5 milligrams (mg) of Cialis daily, how long does it take the drug to work?

Cialis starts working quickly. Studies show that the drug begins to work 30 minutes to 6 hours after you take your first dose. But it may take several days for the medication to reach its full effectiveness. If you don’t notice an improvement in your BPH symptoms or ED within a week of daily use, talk with your doctor. They may need to adjust your dosage.

Could I take an 80-mg dose of Cialis?

No, it’s not safe to take an 80-mg dose of Cialis. The maximum recommended daily dosage of Cialis is 20 mg per day if you take it as needed for ED. If you take Cialis daily, the maximum dosage is 5 mg per day.

Taking doses of Cialis above the recommended limit could lead to serious side effects, such as dangerously low blood pressure or priapism (a painful erection lasting 4 hours or longer).

What’s the typical Cialis dosage for a 70-year-old?

Cialis dosage is not based on your age alone. Instead, your doctor will prescribe the dosage that’s best for your condition. Before prescribing Cialis, your doctor may send you for a blood test to check how well your kidneys and liver are working. This is because they’ll take your kidney and liver health into consideration when determining your dosage.

For many people, their kidneys may not work as well as they age. So if you’re an older adult (ages 65 years and older), it may take longer for your body to break down and clear Cialis from your system. Older adults may also be more sensitive in how they react to Cialis, which may increase their risk for side effects.

If you’re 70 years old, your doctor will likely start you on a low dosage of Cialis. If it works well for you, you’ll probably continue taking a low dosage. If it doesn’t work well for you or you develop bothersome side effects, your doctor will adjust your dosage. The goal is to find the lowest dosage that effectively treats your BPH symptoms or ED without causing bothersome side effects.

If you have questions about what your Cialis dosage should be, talk with your doctor.

How do the dosages for Cialis and Viagra compare?

As ED treatments, both Cialis and Viagra can be taken occasionally (as needed) before sexual activity. The usual dosage for occasional Cialis use is one dose 2 hours before having sex. The usual dosage for occasional Viagra use is one dose 1 hour before having sex.

Cialis is also approved for once-daily dosing for ED, but Viagra is not. This is because the effects of Cialis on ED can last much longer than Viagra’s effects. One dose of Cialis can help improve erectile function for up to 36 hours. In comparison, Viagra’s effects can last up to 4 hours. But on average, its effects start to lessen 2 to 3 hours after you take a dose.

The typical dose for once-daily Cialis for ED is 2.5 milligrams (mg) to 5 mg. When used as needed for ED, the usual Cialis dose is 10 mg (with a maximum daily dose of 20 mg). The typical dose of Viagra for ED is 50 mg.

Talk with your doctor about whether Cialis or Viagra may be a better option for you.

You’ll take Cialis by mouth, either once per day or occasionally (as needed before sex).

The Cialis tablet should be swallowed whole. You can take it with or without food.

With once-daily Cialis, be sure to take it around the same time each day. When you’re taking Cialis once a day, there isn’t a best time to take Cialis. But taking your dose around the same time each day helps to keep a steady level of the drug in your body.

With occasional (as needed) use of Cialis, it’s recommended that you take your dose about 2 hours before having sex. This is because it takes an average of 2 hours for the drug to reach its highest level in your body.

Because this is an average, you may notice better effects if you have sex a little sooner or a little later than this 2-hour timeframe. In studies, Cialis improved erectile function as soon as 30 minutes to as long as 36 hours after a dose was taken.

If you have questions about taking Cialis, talk with your doctor or pharmacist.

Do not use more Cialis than your doctor prescribes. Using more than this can lead to serious side effects.

What to do in case you take too much Cialis

Call your doctor right away if you think you’ve taken/used too much Cialis. You can also call 800-222-1222 to reach the American Association of Poison Control Centers, or use its online resource. But if you have severe symptoms, call 911 (or your local emergency number) immediately or go to the nearest emergency room.

The dosage of Cialis you’re prescribed may depend on several factors. These include:

  • the type and severity of the condition you’re using Cialis to treat
  • your age
  • other conditions you may have, such as kidney or liver problems (see “Dosage adjustments” under “What is Cialis’s dosage?”)

If your doctor prescribes once-daily Cialis for your condition, it’s best to take it around the same time each day. If you miss a dose, take it as soon as possible.

However, you should not take more than one dose of Cialis per day. Doing so could raise your risk for side effects, such as low blood pressure or priapism (a painful erection lasting 4 hours or longer).

If you need help remembering to take your dose of Cialis on time, try using a medication reminder. This can include setting an alarm or downloading a reminder app on your phone. A kitchen timer can work, too.

The sections above describe the typical dosages provided by the drug’s manufacturer. If your doctor recommends Cialis for you, they’ll prescribe the dosage that’s right for you.

Remember, you should not change your dosage of Cialis without your doctor’s recommendation. Only take Cialis exactly as prescribed. Talk with your doctor if you have questions or concerns about your current dosage.

Here are some examples of questions you may want to ask your doctor:

  • How long should I give Cialis a chance to work before talking with my doctor about adjusting my dosage?
  • Is once-daily or occasional dosing of Cialis more effective for erectile dysfunction?
  • How can I tell if my Cialis dosage might need to be lowered?
  • Would a different dosage raise or lower my risk for side effects from this drug?

Q:

My doctor prescribed 10 mg of Cialis for occasional use to treat my erectile dysfunction (ED). I took one dose 2 hours before trying to have sex, but I still couldn’t get an erection. Should I try the same dose again before asking my doctor to increase my dose? Or if it didn’t help the first time, will this drug not work for me at all?

Anonymous

A:

Even though Cialis didn’t work this time, it doesn’t mean the drug won’t work at all or that the dose is too low. You can try taking the same dose but waiting longer before having sex.

The 2-hour timeframe is an average, so some people may notice better effects by having sex a little sooner or a little later after taking their dose. In studies, Cialis improved ED as soon as 30 minutes to as long as 36 hours after a dose was taken.

If the drug still doesn’t work after several attempts, or if you have questions or concerns about using Cialis, talk with your doctor.

The information below describes the usual dosage recommendations for Cialis. But be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.

Dosage for erectile dysfunction (ED)

There are two dosage options when Cialis is used to treat ED: dosage for occasional use and for daily use.

Occasional use for ED

With occasional use, you’ll take Cialis only as needed. You’ll likely take one 10-mg tablet before having sex.

Depending on how well the 10-mg dose works for your ED, your doctor may adjust your dose. It may be decreased to 5 mg or increased to 20 mg. You’ll continue to take it only as needed before sex.

You should not take Cialis more than once per day. You also should not take more than the recommended maximum dosage of Cialis, which is 20 mg per day. Taking higher dosages of Cialis than this, such as 40 mg per day, raises your risk for serious side effects. Examples of these side effects include very low blood pressure and priapism (a painful erection lasting 4 hours or longer).

Daily use for ED

With daily use, you’ll take one dose of Cialis per day. You don’t need to time your dose to be taken before having sex. You should take it around the same time each day.

For daily use of Cialis for ED, the usual starting dosage is 2.5 mg per day. If this dosage isn’t effective for you, your doctor may increase your dosage to 5 mg per day.

Dosage for benign prostatic hyperplasia (BPH)

The usual dosage of Cialis for BPH symptoms is 5 mg once per day for up to 26 weeks. You should take your dose around the same time each day.

Dosage for ED and BPH

If your doctor prescribes Cialis to treat ED along with BPH symptoms, you’ll take Cialis once per day.

For this use, the usual dosage is 5 mg per day. You should not take any additional doses of Cialis for occasional use before sex.

You don’t need to time your dose to be taken before having sex. You should take it around the same time each day.

Is Cialis used long term?

Yes, Cialis is typically used as a long-term treatment. If you and your doctor determine that it’s safe and effective for you, it’s likely that you’ll use Cialis long term.

Dosage adjustments

If you have certain kidney or liver problems, your doctor may prescribe a lower dosage of Cialis for you. This is because, with your condition, the usual dosage may raise your risk for side effects from the drug.

Depending on how severe your kidney or liver problems are, your doctor may recommend occasional dosing instead of daily dosing to treat ED.

How can I get the maximum effect from Cialis?

To get the maximum effect from Cialis, take it exactly as prescribed.

If you’re using once-daily Cialis for either erectile dysfunction (ED) or benign prostatic hyperplasia (BPH), take your dose around the same time each day. This helps keep a consistent amount of the drug in your body to provide the maximum effect. If you forget to take doses, skip doses, or take doses late, the medication won’t work as well.

If you’re prescribed occasional (as needed) Cialis for ED, it’s best to take your dose at least 2 hours before having sex. This is because it takes an average of 2 hours for the drug to reach its highest level in your body.

Because this is an average, you may notice better effects if you have sex a little sooner or a little later than this 2-hour timeframe. In studies, Cialis improved erectile function as soon as 30 minutes to as long as 36 hours after a dose was taken. As long as you do not take more than the maximum daily dose, you can experiment with how long you wait to have sex after taking a dose.

If you have other questions about how to get the most from Cialis, talk with your doctor or pharmacist.

If I take 5 milligrams (mg) of Cialis daily, how long does it take the drug to work?

Cialis starts working quickly. Studies show that the drug begins to work 30 minutes to 6 hours after you take your first dose. But it may take several days for the medication to reach its full effectiveness. If you don’t notice an improvement in your BPH symptoms or ED within a week of daily use, talk with your doctor. They may need to adjust your dosage.

Could I take an 80-mg dose of Cialis?

No, it’s not safe to take an 80-mg dose of Cialis. The maximum recommended daily dosage of Cialis is 20 mg per day if you take it as needed for ED. If you take Cialis daily, the maximum dosage is 5 mg per day.

Taking doses of Cialis above the recommended limit could lead to serious side effects, such as dangerously low blood pressure or priapism (a painful erection lasting 4 hours or longer).

What’s the typical Cialis dosage for a 70-year-old?

Cialis dosage is not based on your age alone. Instead, your doctor will prescribe the dosage that’s best for your condition. Before prescribing Cialis, your doctor may send you for a blood test to check how well your kidneys and liver are working. This is because they’ll take your kidney and liver health into consideration when determining your dosage.

For many people, their kidneys may not work as well as they age. So if you’re an older adult (ages 65 years and older), it may take longer for your body to break down and clear Cialis from your system. Older adults may also be more sensitive in how they react to Cialis, which may increase their risk for side effects.

If you’re 70 years old, your doctor will likely start you on a low dosage of Cialis. If it works well for you, you’ll probably continue taking a low dosage. If it doesn’t work well for you or you develop bothersome side effects, your doctor will adjust your dosage. The goal is to find the lowest dosage that effectively treats your BPH symptoms or ED without causing bothersome side effects.

If you have questions about what your Cialis dosage should be, talk with your doctor.

How do the dosages for Cialis and Viagra compare?

As ED treatments, both Cialis and Viagra can be taken occasionally (as needed) before sexual activity. The usual dosage for occasional Cialis use is one dose 2 hours before having sex. The usual dosage for occasional Viagra use is one dose 1 hour before having sex.

Cialis is also approved for once-daily dosing for ED, but Viagra is not. This is because the effects of Cialis on ED can last much longer than Viagra’s effects. One dose of Cialis can help improve erectile function for up to 36 hours. In comparison, Viagra’s effects can last up to 4 hours. But on average, its effects start to lessen 2 to 3 hours after you take a dose.

The typical dose for once-daily Cialis for ED is 2.5 milligrams (mg) to 5 mg. When used as needed for ED, the usual Cialis dose is 10 mg (with a maximum daily dose of 20 mg). The typical dose of Viagra for ED is 50 mg.

Talk with your doctor about whether Cialis or Viagra may be a better option for you.

You’ll take Cialis by mouth, either once per day or occasionally (as needed before sex).

The Cialis tablet should be swallowed whole. You can take it with or without food.

With once-daily Cialis, be sure to take it around the same time each day. When you’re taking Cialis once a day, there isn’t a best time to take Cialis. But taking your dose around the same time each day helps to keep a steady level of the drug in your body.

With occasional (as needed) use of Cialis, it’s recommended that you take your dose about 2 hours before having sex. This is because it takes an average of 2 hours for the drug to reach its highest level in your body.

Because this is an average, you may notice better effects if you have sex a little sooner or a little later than this 2-hour timeframe. In studies, Cialis improved erectile function as soon as 30 minutes to as long as 36 hours after a dose was taken.

If you have questions about taking Cialis, talk with your doctor or pharmacist.

Do not use more Cialis than your doctor prescribes. Using more than this can lead to serious side effects.

What to do in case you take too much Cialis

Call your doctor right away if you think you’ve taken/used too much Cialis. You can also call 800-222-1222 to reach the American Association of Poison Control Centers, or use its online resource. But if you have severe symptoms, call 911 (or your local emergency number) immediately or go to the nearest emergency room.

The dosage of Cialis you’re prescribed may depend on several factors. These include:

  • the type and severity of the condition you’re using Cialis to treat
  • your age
  • other conditions you may have, such as kidney or liver problems (see “Dosage adjustments” under “What is Cialis’s dosage?”)

If your doctor prescribes once-daily Cialis for your condition, it’s best to take it around the same time each day. If you miss a dose, take it as soon as possible.

However, you should not take more than one dose of Cialis per day. Doing so could raise your risk for side effects, such as low blood pressure or priapism (a painful erection lasting 4 hours or longer).

If you need help remembering to take your dose of Cialis on time, try using a medication reminder. This can include setting an alarm or downloading a reminder app on your phone. A kitchen timer can work, too.

The sections above describe the typical dosages provided by the drug’s manufacturer. If your doctor recommends Cialis for you, they’ll prescribe the dosage that’s right for you.

Remember, you should not change your dosage of Cialis without your doctor’s recommendation. Only take Cialis exactly as prescribed. Talk with your doctor if you have questions or concerns about your current dosage.

Here are some examples of questions you may want to ask your doctor:

  • How long should I give Cialis a chance to work before talking with my doctor about adjusting my dosage?
  • Is once-daily or occasional dosing of Cialis more effective for erectile dysfunction?
  • How can I tell if my Cialis dosage might need to be lowered?
  • Would a different dosage raise or lower my risk for side effects from this drug?

Q:

My doctor prescribed 10 mg of Cialis for occasional use to treat my erectile dysfunction (ED). I took one dose 2 hours before trying to have sex, but I still couldn’t get an erection. Should I try the same dose again before asking my doctor to increase my dose? Or if it didn’t help the first time, will this drug not work for me at all?

Anonymous

A:

Even though Cialis didn’t work this time, it doesn’t mean the drug won’t work at all or that the dose is too low. You can try taking the same dose but waiting longer before having sex.

The 2-hour timeframe is an average, so some people may notice better effects by having sex a little sooner or a little later after taking their dose. In studies, Cialis improved ED as soon as 30 minutes to as long as 36 hours after a dose was taken.

If the drug still doesn’t work after several attempts, or if you have questions or concerns about using Cialis, talk with your doctor.

The first effective drug for the treatment of erectile dysfunction (ED) appeared in 1998 and literally “blew up” the market. It was Viagra, which in 2000 accounted for 90% of sales of drugs to improve potency. But by 2007, this figure had dropped to 50% “thanks” to the analogue of Cialis, which appeared in 2003.

We asked pharmacist Natalya Zotina to tell us more about Cialis: what active ingredient is included in the composition, what side effects and contraindications it has. And also compare the drug with other drugs that are prescribed for ED.

Cialis: composition

Cialis is produced in tablets containing the active substance and excipients. The active substance in the preparation is tadalafil, lactose, hyprolose, sodium lauryl sulfate, cellulose, magnesium stearate are added as auxiliary.

Cialis preparations for men containing tadalafil 5 mg and 20 mg are registered in Russia.

Cialis: active substance

The active substance of Cialis tadalafil inhibits the enzyme phosphodiesterase (PDE-5). As a result, in the presence of nitric oxide, the walls of the vessels of the cavernous bodies are relaxed and filled with blood. This ensures an erection in response to sexual arousal.

The drug itself does not increase sexual desire. If there is no attraction to a partner, then the medicine will not help.

Cialis for men: instructions

Cialis 5 mg is used to treat erectile dysfunction, including lower urinary tract symptoms in benign prostatic hyperplasia.

Cialis 20 mg is used only for ED 30 minutes before intercourse, regardless of food intake. This dosage is not recommended for daily use. With frequent sexual activity, it is better to take Cialis at a dose of 5 mg or even 2.5 mg once a day at the same time. The dose depends on individual sensitivity.

Cialis side effects

The most frequently reported side effects of Cialis are:

  • headache
  • dyspepsia
  • back and muscle pain

Moreover, the frequency of adverse reactions increased with the dose of Cialis. They are transitory. So, a headache with daily use of the drug lasts the first 10-30 days, then it goes away.

Cialis and alcohol are compatible. Simultaneous administration of the drug and ethyl alcohol does not affect the concentration of both substances, does not reduce pressure, and does not affect cognitive functions.

Cialis: contraindications

Cialis should not be administered or taken to patients in the following cases:

  • hypersensitivity to drug components
  • treatment with organic nitrates (nitroglycerin) – pressure reduction possible
  • children under 18 years of age
  • diseases of the cardiovascular system, suggesting restriction of sexual activity: myocardial infarction, unstable angina, chronic heart failure, uncontrolled arrhythmia, hypotension, stroke in the last six months
  • loss of vision in one eye due to optic neuropathy
  • concomitant use of doxazosin and other drugs for the treatment of ED
  • severe renal failure

Cialis or Viagra

Viagra is the first and still popular drug for ED. The drug has two main differences from Cialis: the active substance and the duration of action.

Viagra contains sildenafil, which begins to “work” 30 minutes after taking it for 4 hours. A man can feel the effect of tadalafil in Cialis earlier – after 16 minutes. In this case, the drug maintains an erection for 36 hours. In addition, Cialis achieves the desired effect at a lower dosage: its maximum daily dose is 20 mg versus 100 mg for Viagra. At a lower dose, the risk of developing negative reactions is lower.

The absorption and rate of action of Viagra is affected by food intake. Cialis is devoid of this drawback.

Thanks to its benefits, Cialis quickly became popular in many countries.

Viagra and Cialis are available by prescription. The selection of the optimal remedy should be carried out by the doctor, taking into account the age of the patient, the severity of the condition, concomitant diseases, and medications taken.

Tadalafil or Cialis: which is better?

Drugs with the name Tadalafil are generics of the original Cialis of Russian, Polish, Indian and other countries of origin.

Indications, contraindications, side effects are identical for analogues. The difference is that among Tadalafils you can find dosages of 2.5 mg, 5 mg, 10 mg and 20 mg. This makes it easier for the doctor to select the optimal treatment regimen and saves the patient’s money.

Substances for the production of Tadalafil tablets, mainly of Indian and Chinese origin. The Swiss manufacturer of Cialis uses pharmaceutical raw materials from the USA and Puerto Rico. The cost of Tadalafil is lower than Cialis. The patient can substitute these drugs for each other based on their preferences.

Cialis or Levitra: which is better?

Levitra tablets contain 5, 10 and 20 mg vardenafil. The mechanism of action of Levitra is similar to that of Cialis. Indications for use – erectile dysfunction. Cialis is also prescribed for the treatment of benign prostatic hyperplasia.

The main difference between the drugs is the duration of action. Cialis works up to 36 hours, Levitra 8-12 hours. But the recommended dose for Levitra is less and equal to 10 mg, for Cialis – 20 mg. Therefore, Levitra is preferred to be prescribed to men with chronic diseases to reduce the risk of side effects.

In the case of Cialis, dose adjustment for elderly patients is not required. But if men over 65 plan to take the maximum dose of Levitra 20 mg, it is better to consult a doctor.

Fatty food affects the speed of action of Levitra. Alcohol also impairs erection. Both drugs have their own benefits. The doctor will tell you which of these drugs is suitable for a particular patient.

Zidena or Cialis: which is better?

Zydena is one of the new drugs for the treatment of ED with the active ingredient udenafil. It was registered in Russia in 2008. Zidena is indicated for the treatment of ED only. Unlike Cialis, she has only two contraindications: hypersensitivity and taking nitrate drugs.

Zidena has one dosage form: 100 mg tablets. The maximum daily dosage is 200 mg. The drug begins to act 30 minutes after taking the pill. The period of effectiveness of one dose of Zidena is up to 24 hours (in the presence of sexual arousal). Cialis works faster and longer at a lower dose.

Zidena has a high security profile. The drug does not have such side effects as myalgia and back pain, characteristic of Cialis. The intake of alcohol and fatty foods does not affect the action of udenafil, which makes taking Zydena as convenient as possible for patients.

We recommend that you discuss Zidena or Cialis with your doctor. These drugs are prescription drugs, self-medication and self-administration can harm your health.
