Cialis 20mg: How it Compares to Other ED Treatments

Tadalafil, the active ingredient in the medication Cialis®, is one of the most effective and widely used options on the market for treating erectile dysfunction, or ED.

As with other erectile dysfunction medications, Cialis is available in a variety of dosages. One of the most common forms of Cialis is a 20mg tablet, which is designed for use when needed as a treatment for erectile dysfunction.

If you suffer from erectile dysfunction, using Cialis at a 20mg dosage may make it easier for you to get and keep an erection. However, the 20mg dosage of Cialis isn’t the only way that you can use Cialis, nor is it the only option for treating ED.

Below, we’ve explained how Cialis 20mg works, as well as how it compares to other dosages of Cialis and FDA-approved ED treatments such as Viagra® (sildenafil), Levitra® (vardenafil) and Stendra® (avanafil).

How Cialis Works

How does Cialis work? At a simple level, Cialis works by increasing the amount of blood that can flow into your penis when you receive sexual stimulation.

Tadalafil, the active ingredient in Cialis, belongs to a class of medications referred to as PDE5 inhibitors. It works by inhibiting the actions of the enzyme phosphodiesterase type 5, which is responsible for regulating blood flow to the erectile tissue of your penis.

Erections are all about blood flow. When you’re sexually aroused, your nerves signal to tissue inside your penis called the corpora cavernosa, which relaxes and allows blood to flow in and create pressure.

When you take Cialis, it becomes easier for blood to flow into the corpus cavernosa — the soft, spongy tissue of your penis that fills with blood to become erect. This increased blood flow can help you to get and maintain an erection when you feel sexually aroused.

Cialis differs from other ED medications in several ways, the biggest of which is its long duration of action.

How long does Cialis last? Compared to other ED medications, such as Viagra® (sildenafil) and Levitra® (vardenafil), both of which last for a few hours each, Cialis offers long-lasting effects, with a single dose generally providing relief from ED symptoms for up to 36 hours.

Thanks to its long-lasting effects, Cialis has earned a reputation as a “weekend pill” for treating erectile dysfunction.

Cialis Side Effects

Like other ED medications, Cialis can cause side effects. Most side effects from Cialis are mild, although in rare cases, medications such as Cialis may cause more serious or bothersome side effects.

  • Headaches. Headaches can occur with all ED medications, including Cialis. According to a 2008 review, headaches were reported by 15 percent of men who used Cialis at a dosage of 20mg, making them the most commonly reported adverse effect.
  • Indigestion and heartburn. Cialis and other medications for ED can cause indigestion, or heartburn. This side effect occurs in eight percent of men who use Cialis at a 20mg dosage.
  • Back and/or muscle pain. Cialis can cause back pain and/or myalgia, a form of muscle aches and muscle pain. Three to five percent of men who use Cialis at a dosage of 10 to 20mg report experiencing this side effect.
  • Flushing. Because of its effects on your blood vessels, Cialis may cause you to develop facial flushing. This side effect occurs in around three percent of men who use Cialis. It can also occur with other medications for ED.
  • Nasopharyngitis (cold symptoms). A small percentage of men who use Cialis for ED experience cold-like symptoms, such as nasal congestion (or “stuffy nose”).

In rare cases, Cialis and other medications for ED may cause more serious side effects, such as dizziness, reduced blood pressure, hearing problems, loss of vision or chest pain. It’s important to inform your healthcare provider immediately if you experience any concerning symptoms.

Cialis and other ED medications may also cause priapism, a form of painful, prolonged erection that can damage the tissue of your penis. This is a highly uncommon side effect with few case reports in medical literature.

Our guide to priapism provides more information about this side effect. If you start to develop a long-lasting, uncomfortable or painful erection after taking Cialis, make sure to seek immediate medical help.

Cialis Drug Interactions

Cialis can interact with other medications. Some medications, including those prescribed to treat heart disease or hypertension, can cause dangerous and potentially life threatening side effects when used with Cialis or generic tadalafil.

If you’re prescribed Cialis, it’s important not to take it with nitrates or other heart medications. If used together, these medications can cause a sudden, significant drop in blood pressure. These effects may also occur with street drugs that contain nitrates, such as “poppers.”

To avoid interactions, make sure to inform your healthcare provider about all of the medications you currently use or have recently used before taking Cialis.

Cialis 20mg vs. Other Cialis Dosages

Cialis comes in oral tablet form and is available in several dosages, ranging from just 2.5mg per tablet to 5mg, 10mg and 20mg. The 20mg version of Cialis is currently the maximum dose that’s available.

Some of these Cialis dosages are designed for use as needed (used only before sex), whereas others are designed for use every day. We’ve explained how each cialis dosage differs in more detail below.

Cialis 10mg

The FDA recommends the 10mg version of Cialis as a starting dosage for use as needed as a treatment for erectile dysfunction. If you suffer from ED and want to use Cialis as needed, it’s likely that your healthcare provider will recommend this dosage.

Research shows that the 10mg dosage of Cialis works well for the majority of men affected by erectile dysfunction.

In clinical trials, 68 percent to 77 percent of men with erectile dysfunction who used Cialis at a 10mg dosage were able to have penetrative sex with their partner, compared to 46 percent to 55 percent of men given a non-therapeutic placebo.

As you may expect, Cialis 10mg has a moderately higher rate of side effects than the 5mg and 2.5mg versions of this medication, and a slightly lower rate of side effects than Cialis 20mg.

Cialis 20mg

Cialis is also available as a 20mg tablet. This version of Cialis is the strongest dosage that has been approved for use by the FDA and, just like the 10mg version of Cialis, is designed for use as needed before you have sex.

Your healthcare provider may prescribe the 20mg version of Cialis if you don’t get satisfactory results from the 10mg dosage.

Studies of Cialis 20mg have found that it’s typically more effective than lower-dose versions of Cialis.

In clinical trials, 76 percent to 85 percent of men given this dosage could successfully have sex with their partner, versus 68 percent to 77 percent of men who used Cialis at a 10mg dosage.

Cialis 20mg is slightly more likely to cause certain side effects, such as headache or dyspepsia (indigestion), than the 10mg dosage of Cialis. However, the increased risk of experiencing side effects is fairly small.

Even at the highest dosage of Cialis, side effects are still uncommon. In clinical trials, the most common side effect of Cialis, headache, was only reported by 15 percent of men who used the 20mg version of the medication.

Cialis 5mg

Cialis is available as a 5mg tablet. This version of Cialis can be taken daily (we’re explained this in more detail below) or as needed to treat erectile dysfunction.

Your healthcare provider may suggest using Cialis 5mg if you experience significant side effects from the 10 or 20mg dosages, or if you think that these dosages are more than needed in order to treat your erectile dysfunction.

Research shows that when used as needed, Cialis 5mg is more effective than a non-therapeutic placebo but less effective at treating ED than Cialis 10mg or 20mg.

It’s also slightly less likely to cause common ED medication side effects, such as headache and dyspepsia (indigestion).

Daily Cialis (Cialis 5mg and 2.5mg)

Cialis is also available as a daily-use medication at dosages of 5mg and 2.5mg. These versions of Cialis are designed to be taken daily at the same time, instead of as needed before you have sex.

Taking Cialis daily rather than as needed has some advantages, such as fewer common side effects and a simple dosage schedule. It also means that you’ll be ready to have sex any time during the day, rather than just after taking your medication.

However, it also has some disadvantages, such as side effects that may be more persistent or bothersome. We’ve discussed these in more detail in our full guide to daily-use Cialis.

Cialis 20mg vs. Viagra (Sildenafil)

Cialis is often compared to other ED medications such as Viagra (sildenafil). As a treatment for erectile dysfunction, the 20mg dosage of Cialis offers several advantages compared to Viagra:

  • It’s longer lasting. The effects of Cialis 20mg last for approximately 36 hours, making it a very long-lasting treatment for erectile dysfunction. In comparison, the effects of Viagra tend to fade away after three to five hours. Due to its longer duration of action, as-needed Cialis may be a better choice for you if you want to treat erectile dysfunction for the entire day with a single dose of medication.
  • It’s less affected by food. Cialis is not affected by food, meaning you can take it before or after eating. This may be useful if you plan to take Cialis with dinner in order to have sex later in the nighttime. While it’s also okay to take Viagra with food, taking Viagra after a meal that contains lots of fat may affect the drug’s absorption and slow down its effects.

On the other hand, the 20mg dosage of Cialis also has a variety of disadvantages compared to Viagra:

  • In certain circumstances, it might be too long-lasting. Cialis is famous for providing relief from ED for longer than other medications. However, if you only need to treat your ED symptoms for a night, the 36-hour effects of Cialis may be more than needed.
  • It may cause longer-lasting side effects. Because of Cialis’s long half-life and duration of action, it can cause more persistent side effects than other ED medications. This may be an issue if you’re prone to side effects from PDE5 inhibitors.

Ultimately, Cialis and Viagra are different medications that treat the same condition. The biggest advantage of Cialis is its long duration of action, while the main advantage of Viagra is that it’s a great medication for use as-needed for a single night of sex. There are also chewable Cialis and Viagra, which we detail in our blog.

Our Cialis vs. Viagra guide goes into more detail on the main advantages and disadvantages of both medications, from effectiveness to side effects, ease of use, safety and more.

Cialis 20mg vs. Other ED Medications

In addition to Cialis, other medications, such as Levitra (vardenafil) and Stendra (avanafil) can also treat erectile dysfunction. Like Viagra, these medications differ from the 20mg dosage of Cialis in several ways:

  • Levitra. Levitra typically lasts for slightly longer than Viagra, but is much shorter-acting than Cialis. This makes it a good alternative to Cialis if you’d like to use ED medication as needed, rather than once per 36 hours. Our more detailed Levitra vs. Cialis comparison provides more information on how these popular ED medications differ.
  • Stendra. Stendra is a new medication for ED. It starts working in as little as 15 minutes, making it a much faster-acting medication than Cialis. On average, a dose of Stendra provides relief from ED for approximately four to six hours.As a newer ED medication, Stendra has a lower risk of causing certain side effects than Cialis.

Is Cialis 20mg Right For You?

The 20mg dosage of Cialis is a good option if you want relief from erectile dysfunction that lasts for an entire day or longer, or if you’ve previously used Cialis at a 5mg or 10mg dose and didn’t experience satisfactory effects.

However, it’s slightly more likely to cause side effects than the 10mg version of Cialis, which is why healthcare professionals typically prescribe Cialis at a lower dosage first.

We offer both brand name Cialis and generic tadalafil online. We also offer a range of other ED medications, including Viagra, generic sildenafil and Stendra (avanafil).

All of these medications are effective at treating ED, with each offering its own range of unique advantages and disadvantages.

Tadalafil 20mg Tablets (Generic Cialis)

IMPORTANT: HOW TO USE THIS INFORMATION: This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.

USES: Tadalafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, tadalafil works by increasing blood flow to the penis to help a man get and keep an erection. Tadalafil is also used to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia-BPH). It helps to relieve symptoms of BPH such as difficulty in beginning the flow of urine, weak stream, and the need to urinate frequently or urgently (including during the middle of the night). Tadalafil is thought to work by relaxing the smooth muscle in the prostate and bladder. This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). Practice \”safe sex\” such as using latex condoms. Consult your doctor or pharmacist for more details.

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional. Tadalafil is also available in another brand for high blood pressure in the lungs (pulmonary hypertension).

HOW TO USE: Read the Patient Information Leaflet provided by your pharmacist before you start taking tadalafil and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth, with or without food, as directed by your doctor. Do not take tadalafil more often than once daily. The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). To treat the symptoms of BPH, take this medication as directed by your doctor, usually once a day. If you are also taking finasteride with this medication to treat symptoms of BPH, talk with your doctor about how long you should continue taking this medication. To treat erectile dysfunction-ED, there are 2 ways that tadalafil may be prescribed. Your doctor will determine which is the best way for you to take tadalafil. Follow your doctor\’s directions exactly since your dosage depends on how you are taking it. The first way is to take it as needed, usually at least 30 minutes before sexual activity. Tadalafil\’s effect on sexual ability may last up to 36 hours. The second way to treat ED is to take tadalafil regularly, once a day every day. If you take it this way, you may attempt sexual activity at any time between your doses. If you are taking tadalafil to treat both ED and BPH, take it as directed by your doctor, usually once a day. You may attempt sexual activity at any time between your doses. If you are taking tadalafil once daily for BPH, or for ED, or for both, take it regularly to get the most benefit from it. To help you remember, take it at the same time each day. Tell your doctor if your condition does not improve or if it worsens.

SIDE EFFECTS: Headache, stomach upset, back pain, muscle pain, stuffy nose, flushing, or dizziness may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Sexual activity may put extra strain on your heart, especially if you have heart problems. If you have heart problems and experience any of these serious side effects while having sex, stop and get medical help right away: severe dizziness, fainting, chest/jaw/left arm pain, nausea. Rarely, sudden decreased vision, including permanent blindness, in one or both eyes (NAION) may occur. If this serious problem occurs, stop taking tadalafil and get medical help right away. You have a slightly greater chance of developing NAION if you have heart disease, diabetes, high cholesterol, certain other eye problems (\”crowded disk\”), high blood pressure, if you are over 50, or if you smoke. Rarely, a sudden decrease or loss of hearing, sometimes with ringing in the ears and dizziness, may occur. Stop taking tadalafil and get medical help right away if these effects occur. In the rare event you have a painful or prolonged erection lasting 4 or more hours, stop using this drug and get medical help right away, or permanent problems could occur. A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

INTRODUCTION

CIALIS 20MG TABLET contains Tadalafil which belongs to the group of medicines called Phosphodiesterase type 5 (PDE 5) inhibitors. It is used in adults to treat erectile dysfunction (in men) and pulmonary arterial hypertension (PAH).

Erectile dysfunction (also known as impotence) is a sexual condition where a man cannot sustain a hard erected penis that is required for a normal sexual activity. It happens due to decreased blood flow to the penis.

PAH can be defined as increased blood pressure in the blood vessels that supply the lungs. It can be caused due to narrowing of blood vessels (arteries) supplying the heart and the lungs. Symptoms of PAH might include shortness of breath, tiredness, weakness and feeling faint.

CIALIS 20MG TABLET is not an aphrodisiac (sex-stimulating agent). Therefore, it cannot be used to induce sexual thoughts or can improve sexual performance/pleasure in healthy men. It would help you to get an erection only if you are sexually stimulated. It is also not suitable for use in healthy men who do not have erectile dysfunction.

Avoid consuming alcohol or grapefruit juice while taking CIALIS 20MG TABLET, as it may lead to unwanted side effects. Before taking CIALIS 20MG TABLET, inform your doctor if you have any liver, kidney or heart problems. You must also inform your doctor if you have any deformity in your penis or have undergone surgical removal of the whole or a part of the prostate gland.

CIALIS 20MG TABLET is not recommended for use in patients with severely low or high blood pressure and in patients who recently had a stroke. It is also not suitable for use in pregnant or breastfeeding women unless considered necessary by the physician.

The most common side effects of taking CIALIS 20MG TABLET are flushing, headache, dizziness, blurred vision and muscle pain. Consult your doctor if any of these side effects troubles you. You must also inform your doctor if you experience any painful and prolong erection after taking CIALIS 20MG TABLET.

USES OF CIALIS 20MG TABLET

HOW CIALIS 20MG TABLET WORKS

CIALIS 20MG TABLET works by blocking the effects of certain enzymes (PDE5) in the body that limits blood flow to the penis. This relaxes the blood vessels supplying the penis, improves blood flow to the penis and makes it stay erect throughout the process of sexual intercourse.

It also relaxes the blood vessels supplying the lungs which enable the blood to flow more smoothly within them with less pressure, leading to reduction in the signs of pulmonary arterial hypertension.

DIRECTIONS FOR USE

Take CIALIS 20MG TABLET preferably before meals and at least 1 hour before sexual intercourse or as advised by your physician. Swallow the medicine with a glass of water. Do not crush or chew the medicine.

Your doctor will decide the correct dose and duration of therapy for you depending on your age, body weight and disease condition.
