Understanding Cialis: An Overview of the Medication

Cialis, known by its generic name tadalafil, is a prescription medication primarily used to treat erectile dysfunction (ED) and benign prostatic hyperplasia (BPH) in adult males. As a member of the phosphodiesterase-5 (PDE5) inhibitor class of drugs, Cialis works by improving blood flow to specific areas of the body.

Available as oral tablets, Cialis offers flexibility in dosing options to cater to individual patient needs. Its effectiveness in treating both ED and BPH has made it a popular choice among healthcare providers and patients alike.

Cialis Strengths: Breaking Down the Available Options

Cialis comes in four distinct strengths, each designed to address specific treatment requirements:

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

The variety of strengths allows healthcare providers to tailor the treatment to each patient’s unique needs, ensuring optimal efficacy while minimizing potential side effects.

Which strength is right for you?

The appropriate Cialis strength depends on various factors, including the condition being treated, individual response to the medication, and any existing health conditions. Your healthcare provider will determine the most suitable strength based on a thorough evaluation of your medical history and current health status.

Dosage Guidelines for Erectile Dysfunction (ED)

When it comes to treating erectile dysfunction, Cialis offers two distinct dosing approaches: daily use and occasional use. Each method has its own recommended dosage guidelines.

Daily Use for ED

For those opting for daily Cialis use to treat ED, the following guidelines apply:

• Starting dose: 2.5 mg once per day
• Timing: Can be taken at any time of day, but consistency is key
• Dose adjustment: May be increased to 5 mg if needed

The daily dosing regimen allows for spontaneity in sexual activity, as the medication maintains a constant presence in the system.

Occasional Use for ED

For those who prefer to take Cialis on an as-needed basis, the dosage recommendations are as follows:

• Initial dose: 10 mg taken before sexual activity
• Dose range: May be adjusted to 5 mg or increased to 20 mg based on efficacy and tolerability
• Maximum frequency: No more than one dose per day

With occasional use, Cialis has demonstrated effectiveness for up to 36 hours after administration, providing an extended window of opportunity for sexual activity.

Treating Benign Prostatic Hyperplasia (BPH) with Cialis

For men dealing with benign prostatic hyperplasia, Cialis offers a straightforward dosing approach:

• Recommended dose: 5 mg taken once daily
• Timing: Can be taken at any time of day, but consistency is important

This daily regimen helps alleviate BPH symptoms by relaxing smooth muscle in the prostate and bladder.

Can Cialis treat both ED and BPH simultaneously?

Indeed, Cialis can be prescribed as a single medication to address both erectile dysfunction and benign prostatic hyperplasia concurrently. In such cases, the recommended dosage is 5 mg taken once daily, providing relief for both conditions with a single treatment regimen.

Long-Term Use of Cialis: What You Need to Know

Cialis is generally considered safe and effective for long-term use, even when prescribed for occasional treatment of ED. The decision to continue Cialis as a long-term treatment should be made in consultation with your healthcare provider, taking into account your overall health status and response to the medication.

Monitoring long-term efficacy and safety

Regular follow-up appointments with your healthcare provider are essential when using Cialis long-term. These check-ins allow for monitoring of the medication’s ongoing effectiveness and the potential development of any side effects or complications.

Safety Considerations: Maximum Dosage and Potential Risks

While Cialis is generally well-tolerated, it’s crucial to adhere to recommended dosage guidelines to minimize the risk of adverse effects.

Is there a maximum safe dose of Cialis?

The maximum recommended dosage of Cialis is 20 mg once per day. Exceeding this dose can significantly increase the risk of side effects, some of which may be severe.

Taking a 40 mg dose of Cialis, for example, is not considered safe and could lead to serious complications, including:

• Dangerous drops in blood pressure
• Priapism (a painful, prolonged erection)
• Increased severity of common side effects

It’s imperative to take Cialis exactly as prescribed by your healthcare provider and never adjust the dose without medical supervision.

Cialis Dosage for Older Adults: Special Considerations

For adults aged 70 and older, Cialis dosages generally align with those recommended for younger adults. However, some important considerations come into play when prescribing Cialis to older individuals:

• Increased sensitivity: Older adults may be more susceptible to the effects of Cialis
• Potential for lower starting doses: Healthcare providers may initiate treatment with lower doses to assess tolerability
• Careful monitoring: Close observation for side effects is crucial in this population

As with all medications, the benefits and risks of Cialis use in older adults should be carefully weighed by healthcare providers on an individual basis.

Adjusting dosages for older patients

While the standard dosage recommendations apply to older adults, healthcare providers may opt for more conservative dosing strategies. This might involve starting with the lowest available dose (2.5 mg) and gradually increasing if necessary, based on the patient’s response and tolerability.

Optimizing Cialis Effectiveness: Tips for Proper Use

To maximize the benefits of Cialis while minimizing potential side effects, consider the following tips:

• Consistency is key: If taking Cialis daily, try to take it at the same time each day
• Avoid grapefruit: Grapefruit and grapefruit juice can interact with Cialis, potentially increasing side effects
• Limit alcohol consumption: Excessive alcohol use can diminish the effectiveness of Cialis and increase the risk of side effects
• Communicate with your healthcare provider: Report any side effects or changes in effectiveness promptly
• Be patient: It may take time to find the optimal dose for your individual needs

How can you ensure you’re taking Cialis correctly?

To ensure proper use of Cialis:

1. Follow your healthcare provider’s instructions precisely
2. Read the medication guide provided with your prescription
3. Ask your pharmacist or doctor if you have any questions about dosing or administration
4. Never exceed the prescribed dose or frequency of use
5. Store the medication as directed, typically at room temperature away from moisture and heat

By adhering to these guidelines, you can help ensure that you’re using Cialis safely and effectively.

Understanding Cialis’s Duration of Action

One of the notable features of Cialis is its extended duration of action, particularly when used for erectile dysfunction treatment.

How long do the effects of Cialis typically last?

When taken for occasional use in treating ED, Cialis has demonstrated effectiveness for up to 36 hours after administration. This prolonged window of action has earned Cialis the nickname “the weekend pill,” as it allows for greater spontaneity in sexual activity compared to some other ED medications.

It’s important to note, however, that the duration of action can vary among individuals based on factors such as:

• Metabolism
• Overall health status
• Other medications being taken
• Dosage strength

While Cialis may remain effective for up to 36 hours, this doesn’t mean a sustained erection for that entire period. Instead, it indicates the timeframe during which the medication can help facilitate an erection when sexual stimulation occurs.

Daily use vs. occasional use: Impact on duration

For those taking Cialis daily for ED or BPH treatment, the medication maintains a constant presence in the system, providing ongoing relief of symptoms. This approach eliminates the need to time doses around sexual activity and may be preferred by some patients and their partners.

Occasional use, on the other hand, offers the flexibility to take Cialis as needed, with effects lasting for an extended period after each dose. This approach may be suitable for those who engage in sexual activity less frequently or prefer not to take daily medication.

Potential Side Effects and Interactions of Cialis

While Cialis is generally well-tolerated, like all medications, it can cause side effects in some individuals. Understanding these potential effects and how to manage them is crucial for safe and effective use of the medication.

What are the most common side effects of Cialis?

The most frequently reported side effects of Cialis include:

• Headache
• Indigestion or heartburn
• Back pain
• Muscle aches
• Flushing
• Stuffy or runny nose

These side effects are typically mild and often resolve on their own as the body adjusts to the medication. If side effects persist or become bothersome, consult your healthcare provider for guidance.

Are there any serious side effects to be aware of?

While rare, Cialis can potentially cause more serious side effects, including:

• Sudden vision loss in one or both eyes
• Sudden hearing decrease or loss
• Priapism (an erection lasting longer than 4 hours)
• Chest pain or irregular heartbeat
• Severe dizziness or fainting

If you experience any of these serious side effects, seek immediate medical attention.

Drug interactions with Cialis

Cialis can interact with various medications, potentially altering its effectiveness or increasing the risk of side effects. Some notable interactions include:

• Nitrates (e.g., nitroglycerin): Can cause a dangerous drop in blood pressure
• Alpha-blockers: May lead to increased risk of dizziness or fainting
• Other ED medications: Combining Cialis with other PDE5 inhibitors is not recommended
• Certain antifungal and antibiotic medications: May affect Cialis metabolism
• HIV protease inhibitors: Can increase Cialis levels in the blood

Always inform your healthcare provider about all medications, supplements, and herbal products you’re taking to avoid potential interactions.

Cialis vs. Other ED Medications: A Comparative Analysis

While Cialis is a popular choice for treating erectile dysfunction, it’s not the only option available. Understanding how Cialis compares to other ED medications can help patients and healthcare providers make informed decisions about treatment.

How does Cialis differ from Viagra and Levitra?

The main differences between Cialis, Viagra (sildenafil), and Levitra (vardenafil) include:

• Duration of action: Cialis can work for up to 36 hours, while Viagra and Levitra typically last 4-5 hours
• Onset of action: Cialis may take 30-60 minutes to take effect, similar to Viagra and Levitra
• Food interactions: Cialis is less affected by food intake compared to Viagra and Levitra
• Dosing options: Cialis offers both daily and as-needed dosing, while Viagra and Levitra are typically used as needed

Each medication has its own unique profile of benefits and potential side effects, and the choice between them often comes down to individual patient factors and preferences.

Is Cialis more effective than other ED medications?

Effectiveness can vary among individuals, and no single ED medication is universally superior to others. Some studies suggest that Cialis may have certain advantages:

• Longer duration of action, allowing for greater spontaneity
• Potential for improved sexual satisfaction due to reduced time pressure
• Option for daily dosing, which some patients prefer

However, the most effective medication can only be determined through individual trial and consultation with a healthcare provider.

The Future of ED Treatment: Emerging Therapies and Research

While medications like Cialis have revolutionized the treatment of erectile dysfunction, ongoing research continues to explore new therapies and approaches to managing this common condition.

What new treatments for ED are on the horizon?

Some promising areas of research in ED treatment include:

• Gene therapy: Targeting specific genetic factors associated with ED
• Stem cell treatments: Potentially regenerating damaged erectile tissue
• Novel drug delivery systems: Exploring new ways to administer ED medications for improved efficacy and reduced side effects
• Combination therapies: Investigating the potential benefits of combining different treatment modalities
• Psychosexual interventions: Developing more effective psychological approaches to complement medical treatments

While these potential therapies are still in various stages of research and development, they offer hope for even more effective and personalized ED treatments in the future.

Will Cialis remain a leading ED treatment in the coming years?

Given its proven efficacy, favorable side effect profile, and unique long-acting properties, Cialis is likely to remain a prominent option in ED treatment for the foreseeable future. However, as new treatments emerge and our understanding of erectile dysfunction evolves, the landscape of ED therapy may continue to change and expand.

Patients and healthcare providers should stay informed about new developments in ED treatment while continuing to utilize established, effective medications like Cialis when appropriate.

But you should try to take it at the same time every day. This helps make sure there’s enough medication in your body for Cialis to be effective.

Long-term use

Doctors recommend using Cialis as a long-term treatment, even if you take it only on occasion to treat ED. If you and your doctor determine that Cialis is safe and effective for you, you’ll likely take it long term.

Below are some answers to frequently asked questions about Cialis dosages.

Is a 40-mg dose of Cialis safe to take?

No, 40 milligrams (mg) is not a safe dose of Cialis to take. The maximum recommended dosage of Cialis is 20 mg once per day. Taking a dose of Cialis that’s higher than recommended could increase your risk for side effects. These can include serious side effects such as drops in blood pressure or priapism (a painful erection that won’t go away).

It’s important to not take more Cialis than the dose your doctor recommends. You should take Cialis exactly as it’s prescribed for you. If you have other questions about Cialis doses, talk with your doctor or pharmacist.

What’s the Cialis dosage for someone who’s 70 years old?

Cialis dosages for someone who is age 70 years (and older adults in general) are the same as those for other adults. Details about these dosages are in the “Cialis dosage” section above.

Older adults may be more sensitive to the effects of Cialis. Because of this, your doctor may decide to prescribe a lower dose than usual when you start taking Cialis. Then, if needed, they can adjust it over time to reach the amount that’s right for you.

If you have additional questions about the use of Cialis in older adults, talk with your doctor or pharmacist.

It’s important that you do not use more Cialis than your doctor prescribes. For some medications, taking more than the recommended amount may lead to side effects or overdose.

If you take more than the recommended amount of Cialis

Call your doctor right away if you believe you’ve taken too much Cialis. Another option is to call America’s Poison Centers at 800-222-1222 or use its online tool. If you have severe symptoms, immediately call 911 or your local emergency number, or go to the nearest emergency room.

The Cialis dosage your doctor prescribes will depend on several factors. These include:

• the type and severity of the condition you’re using Cialis to treat
• how often you take Cialis
• your age
• other medications you may take
• side effects that you may have from taking Cialis
• how well the medication is working for you, if used to treat erectile dysfunction (ED)

Other medical conditions you have can also affect your Cialis dosage.

Dosage adjustments

If you have kidney or liver problems, your doctor may adjust your Cialis dosage. If the kidney or liver problems are mild or moderate, you’ll likely need a lower dose of the drug than usual. Keep in mind that if you have severe liver problems, you should not use Cialis. The drug is also not recommended for daily use if you have severe kidney problems.

Your doctor can determine the severity of your kidney or liver problems and whether Cialis is a safe medication for you to take. Talk with your doctor or pharmacist if you have questions about Cialis dosage adjustments.

Cialis comes as oral tablets. You can take them with or without food.

If you take Cialis for occasional use to treat erectile dysfunction (ED), you should take your dose before sexual activity. When taken for occasional use to treat ED, the effects of Cialis have been shown to last up to 36 hours.

If you take Cialis daily for ED, benign prostatic hyperplasia (BPH), or both ED and BPH, you can take your dose at any time of day. But you should try to take your dose at the same time every day.

You should not take more than one dose of Cialis per day. Be sure not to take more of the drug than your doctor prescribes for you. Doing so may lead to serious side effects from Cialis.

If you have questions about how to take Cialis, talk with your doctor or pharmacist.

If you forget to take a once-daily dose of Cialis, try to take it as soon as you remember. But keep in mind that you should not take more than one Cialis dose per day. So if you missed a dose yesterday, skip that dose and take your next scheduled dose of Cialis.

It’s important that you do not take more Cialis than your doctor prescribes for you. Doing so may lead to serious side effects from the drug.

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or timer on your phone or downloading a reminder app. A kitchen timer can work, too.

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?

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.
