Erectile Dysfunction Home > Cialis

Cialis is a medication that has been licensed for the treatment of erectile dysfunction (ED). In previous clinical studies, up to 78 percent of men reported that the drug allowed them to have successful intercourse. In most cases, Cialis starts working within an hour. The most common side effects include facial flushing, headache, and indigestion. This medication can also be used to treat an enlarged prostate.

What Is Cialis?

Cialis® (tadalafil) is a prescription medication used for treating problems with obtaining or maintaining an erection. It is also used for treating an enlarged prostate, also known as benign prostatic hyperplasia (BPH).
 

Who Makes It?

Cialis is manufactured by Eli Lilly and Company.
 

What Is Cialis Used For?

Cialis has been licensed to treat erectile dysfunction. Erectile dysfunction (ED), also known as impotence, can be a total inability to achieve erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. Essentially, erectile dysfunction is the repeated inability to get or keep an erection firm enough for sexual intercourse.
 
More recently, Cialis was also approved for the treatment of the symptoms of an enlarged prostate.
 

How Does It Work?

Cialis works by blocking a chemical that reverses an erection by allowing blood to flow out of the penis. More blood in the penis means an improved erection. For enlarged prostate symptoms, it is thought that Cialis probably works by relaxing the bladder and the prostate.
