Cialis Drug Information

Men who have erectile dysfunction (ED) may be prescribed the drug Cialis® (tadalafil). It is also approved to treat enlarged prostate symptoms. This medication works by blocking the chemical process that causes blood to flow out of the penis. More blood flow in the penis leads to an improved erection.
 
Cialis comes in tablet form and can be taken either prior to sexual activity or once a day. The drug should be taken with a glass of water; whether you take it with food or not is up to you.
 
While most men have no problems during treatment with Cialis, side effects are possible. Some men are more likely to have an adverse reaction to this drug. Informing your healthcare provider about all medical conditions you have (including heart problems) and any medications you are taking (including vitamins and supplements) will help determine if Cialis is right for you.
