7 FAQs about Cialis

Cialis and its generic equivalent, tadalafil, offer men with erectile dysfunction a choice of treatment modalities. The drugs can be taken on demand or on a daily basis. 

Introduced on the U.S. market in late 2003, Cialis is one of the most popular erectile dysfunction drugs available. Here a few of the most frequently asked questions about the medication.

1. What sets Cialis apart from other ED drugs?

Perhaps the single biggest difference between Cialis and the other oral ED drugs known as PDE5 inhibitors is the extraordinarily lengthy half-life of tadalafil, the active ingredient in Cialis. Tadalafil’s half-life is 17.5 hours, meaning that it take 17.5 hours for blood levels of the drug’s active ingredient to be reduced by half. Because of this lengthy half-life, the effects of Cialis on demand (10- and 20-milligram tablets) can last for up to 36 hours, far longer than any of the other ED drugs.

2. What is daily Cialis therapy?

Thanks to the relatively long half-life of its active ingredient, Cialis became an ideal candidate for a drug that could be taken in lower-strength doses on a daily basis to ensure that users were ready for sex whenever the time is right. The recommended starting dose for daily Cialis therapy is 5 milligrams, which can be adjusted downward to 2.5 milligrams if the higher dose proves too strong. After less than a week on the daily therapy, users should be able to get and keep an erection whenever the need arises.

3. Is a generic equivalent of Cialis available on the U.S. market?

Cialis’s generic equivalent is tadalafil, which is also the active ingredient in the brand-name medication. It debuted on the U.S. market in late September 2018. As is true with generics in general, it offers a lower-cost alternative to the brand-name drug.

4. Do Cialis and tadalafil have side effects?

Rare, indeed, is the medication that has no side effects at all. Among the most common side effects of Cialis and tadalafil are back pain, flushing, headache, indigestion, muscle ache, and runny or stuffy nose. These are generally mild and may disappear altogether after the drug has been taken for a while. Although rare, both Cialis and tadalafil have a handful of side effects that constitute medical emergencies if they should occur. These are priapism, an erection that persists for more than four hours; and a sudden decrease or total loss of either hearing or vision.

5. Is Cialis better than Viagra?

Each of the two most popular ED drugs has its pros and cons. It’s really impossible to say that one is better than the other, although individual users may find that one of the two drugs — or its generic equivalent — works best for them. If either of these drugs causes bothersome side effects in an individual user, the other one might be the better choice. However, because the effects of Cialis are much longer-lasting than those of Viagra, whatever side effects Cialis does cause are likely to be longer in duration as well.

6. How long before Cialis takes effect?

As previously noted, Cialis is the longest-lasting ED drug by far. However, it also takes a bit more time to take full effect. According to WebMD, it can take up to two full hours for its active ingredient to reach maximum concentration in your bloodstream. However, you may still be able to get an erection in as little as 30 minutes after taking the pill.

7. Who shouldn’t take Cialis or tadalafil?

Men who take nitrate-based drugs for the treatment of angina or intractable high blood pressure should not take Cialis or tadalafil. Nor should men who use the recreational drugs known as “poppers,” which also contain nitrates. Both tadalafil and nitrates lower blood pressure. Taken together, they could cause a life-threatening drop in blood pressure.

Neither Cialis nor tadalafil should be used by men who take guanylate cyclase stimulators such as Riociguat. These drugs are most often prescribed for the treatment of pulmonary hypertension, a form of high blood pressure that targets the lungs.
