DRUG INTERACTIONS

But not all research agrees — a smaller daily dose may be just as effective as the as-needed Cialis treatment. A systematic review and meta-analysis examined six randomized controlled trials involving more than 1,500 people and compared an as-needed tadalafil treatment to a once-a-day dose. The results showed that both treatments were about equally effective. While Cialis works similarly to Viagra®, Cialis lasts longer in your body. In fact, Cialis is known as the “weekend pill” for its long half-life. Because you can pop one pill and have sex whenever you like over the next 36 hours (give or take a few hours), it offers more spontaneity. In comparison, avanafil only lasts up to six hours, and Viagra only lasts up to four hours.

You don’t need to take it every day. Depending on your preference and lifestyle, you may not want to take Cialis day in and day out. In fact, the 20 mg dose of Cialis should only be taken as needed. Side effects of Cialis are usually mild and should go away on their own — although they may be worse with higher doses. For example, in clinical trials, 11 percent of people taking tadalafil 10 mg got a headache, whereas 15 percent of those taking tadalafil 20 mg got a headache. Some side effects have the same likelihood in both doses, such as flushing and limb pain. If the side effects of Cialis 20 mg are too much, a healthcare provider may reduce your dose. If this is a particularly annoying side effect of other ED medications, switching to Cialis may be the answer.
