Understanding Cialis: A Powerful Treatment for ED and BPH

Cialis, known generically as tadalafil, is a medication that has revolutionized the treatment of erectile dysfunction (ED) and benign prostatic hyperplasia (BPH) in adult males. As a member of the phosphodiesterase 5 (PDE5) inhibitor drug class, Cialis works by relaxing blood vessels and muscles in specific areas of the body to improve blood flow and alleviate symptoms associated with these conditions.

How Does Cialis Work?

For ED treatment, Cialis enhances blood flow to the penis, facilitating and maintaining erections. In BPH cases, it relaxes bladder muscles, easing urinary symptoms. This dual-action capability makes Cialis a versatile and effective medication for many patients.

Cialis Dosage Forms and Strengths: Tailored for Individual Needs

Cialis is available in tablet form, designed for oral administration. The medication comes in four distinct strengths to accommodate various treatment regimens and patient needs:

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

The availability of multiple strengths allows healthcare providers to tailor treatment plans to individual patient requirements, ensuring optimal efficacy while minimizing potential side effects.

Dosage Guidelines for Erectile Dysfunction (ED)

When prescribing Cialis for ED, healthcare providers typically choose between two dosing strategies: occasional use or daily administration. The choice depends on factors such as patient preference, lifestyle, and the severity of ED symptoms.

Occasional Use Dosage for ED

For patients opting for occasional use:

• Initial dosage: 10 mg taken before sexual activity
• Dosage adjustment: May be decreased to 5 mg or increased to 20 mg based on efficacy and tolerability
• Maximum dosage: 20 mg per day

It’s crucial to note that Cialis should not be taken more than once daily, regardless of the dosage strength. Exceeding the recommended maximum dosage of 20 mg per day significantly increases the risk of serious side effects, including dangerously low blood pressure and priapism (a painful, prolonged erection lasting 4 hours or more).

Daily Use Dosage for ED

For patients preferring daily administration:

• Starting dosage: 2.5 mg once daily
• Dosage adjustment: May be increased to 5 mg daily if needed

Daily use eliminates the need to time doses around sexual activity, providing continuous coverage and potentially improving spontaneity in intimate relationships.

Cialis Dosage for Benign Prostatic Hyperplasia (BPH)

When treating BPH symptoms, Cialis is typically prescribed as a once-daily medication:

• Standard dosage: 5 mg once daily
• Treatment duration: Up to 26 weeks

Consistency in taking the medication at approximately the same time each day is key to maintaining steady drug levels and achieving optimal symptom relief.

Combination Therapy: Treating ED and BPH Simultaneously

For patients experiencing both ED and BPH symptoms, Cialis offers a unique advantage as a single medication capable of addressing both conditions:

• Recommended dosage: 5 mg once daily
• Administration: Taken at approximately the same time each day

This combination therapy approach simplifies treatment regimens and may improve patient adherence.

Factors Influencing Cialis Dosage Adjustments

Several factors may necessitate dosage adjustments for Cialis:

Kidney Function

Patients with impaired kidney function may require lower doses or less frequent administration of Cialis. The severity of kidney impairment plays a crucial role in determining the appropriate dosage modification.

Liver Function

Similarly, individuals with liver problems may need dosage adjustments. The extent of liver dysfunction influences the specific modifications required to ensure safe and effective treatment.

Drug Interactions

Certain medications can interact with Cialis, potentially affecting its metabolism or enhancing its effects. In such cases, dosage adjustments or alternative treatments may be necessary to avoid adverse interactions.

Maximizing the Effectiveness of Cialis Treatment

To achieve optimal results with Cialis, patients should adhere to the following guidelines:

1. Take the medication exactly as prescribed by your healthcare provider.
2. For daily dosing regimens, take Cialis at approximately the same time each day to maintain consistent drug levels in the body.
3. Avoid skipping doses or taking doses late, as this can compromise the medication’s effectiveness.
4. If using Cialis for occasional ED treatment, plan ahead and take the medication at least 30 minutes before sexual activity.
5. Be patient, as it may take several doses before experiencing the full benefits of Cialis, particularly when starting a new dosing regimen.

Long-Term Use and Safety Considerations

Cialis is generally considered safe for long-term use when taken as directed. However, ongoing communication with your healthcare provider is essential to monitor for potential side effects and assess the continued appropriateness of the treatment.

Regular Check-ups

Periodic evaluations allow healthcare providers to:

• Assess the medication’s ongoing effectiveness
• Monitor for any changes in health status that may affect Cialis use
• Make necessary dosage adjustments
• Address any concerns or side effects experienced by the patient

By maintaining open communication and adhering to prescribed dosing regimens, patients can maximize the benefits of Cialis while minimizing potential risks associated with long-term use.

Understanding Cialis Side Effects and Risk Mitigation

While Cialis is generally well-tolerated, it’s important for patients to be aware of potential side effects and strategies to mitigate risks:

Common Side Effects

Some patients may experience:

• Headache
• Indigestion
• Back pain
• Muscle aches
• Flushing
• Nasal congestion

These effects are typically mild and often resolve on their own as the body adjusts to the medication.

Serious Side Effects

Although rare, serious side effects may include:

• Sudden vision or hearing loss
• Prolonged erections (priapism)
• Severe drop in blood pressure

Patients experiencing these symptoms should seek immediate medical attention.

Risk Mitigation Strategies

To minimize the risk of adverse effects:

1. Always take Cialis as prescribed
2. Inform your healthcare provider of all medications and supplements you’re taking
3. Avoid consuming large amounts of alcohol while using Cialis
4. Do not use nitrate medications concurrently with Cialis
5. Report any unusual side effects to your healthcare provider promptly

By following these guidelines and maintaining open communication with healthcare providers, patients can safely and effectively manage their ED or BPH symptoms with Cialis.

Cialis vs. Other ED Medications: Comparing Treatment Options

While Cialis is a highly effective treatment for ED and BPH, it’s not the only option available. Understanding how Cialis compares to other medications can help patients and healthcare providers make informed decisions about treatment plans.

Cialis vs. Viagra (Sildenafil)

Key differences include:

• Duration of action: Cialis can work for up to 36 hours, while Viagra typically lasts 4-5 hours
• Onset of action: Cialis may take 30-60 minutes to work, compared to 30-60 minutes for Viagra
• Food interactions: Cialis is less affected by food intake than Viagra

Cialis vs. Levitra (Vardenafil)

Notable distinctions:

• Duration: Cialis lasts significantly longer than Levitra, which typically works for 4-5 hours
• Dosing options: Cialis offers both daily and as-needed dosing, while Levitra is primarily used as needed
• BPH treatment: Cialis is approved for BPH treatment, while Levitra is not

Cialis vs. Stendra (Avanafil)

Key comparisons:

• Speed of onset: Stendra may work slightly faster than Cialis, with some patients experiencing effects in as little as 15 minutes
• Duration: Cialis offers a longer duration of action compared to Stendra’s 6-12 hour window
• Side effect profile: Both medications are generally well-tolerated, but individual experiences may vary

The choice between Cialis and other ED medications depends on various factors, including individual patient needs, lifestyle considerations, and potential drug interactions. Consulting with a healthcare provider can help determine the most appropriate treatment option.

Cialis and Lifestyle Factors: Optimizing Treatment Outcomes

While Cialis can be highly effective in treating ED and BPH, certain lifestyle factors can impact its efficacy and overall treatment outcomes. Understanding and addressing these factors can help patients maximize the benefits of their Cialis regimen.

Stress Management

Reducing stress can improve sexual function and BPH symptoms:

• Practice relaxation techniques such as deep breathing, meditation, or yoga
• Prioritize sleep and maintain a consistent sleep schedule
• Consider counseling or therapy to address any underlying psychological factors contributing to ED or BPH

Alcohol and Substance Use

Moderating alcohol and avoiding certain substances can improve Cialis efficacy:

• Limit alcohol consumption, as excessive drinking can interfere with sexual function
• Avoid illicit drugs, which can negatively impact sexual health and overall well-being
• If you smoke, consider quitting or reducing tobacco use, as smoking can exacerbate ED symptoms

By incorporating these lifestyle modifications alongside Cialis treatment, patients may experience enhanced symptom relief and improved overall health outcomes.

Future Developments in ED and BPH Treatment: Beyond Cialis

While Cialis has proven to be a highly effective treatment for ED and BPH, ongoing research continues to explore new therapies and treatment modalities. Understanding potential future developments can help patients and healthcare providers stay informed about emerging options in the field.

While these developments are promising, it’s important to note that many are still in the research phase and may take years to become available as approved treatments. Patients should continue to work closely with their healthcare providers to manage their ED and BPH symptoms using currently available therapies, including Cialis, while staying informed about potential future options.

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.

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.
