Tadalafil

Tadalafil is a prescription drug that has been licensed for the treatment of erectile dysfunction (ED), or impotence. It can also be used to treat the symptoms of an enlarged prostate. The drug works by blocking a chemical that reverses an erection by causing blood to flow out of the penis. Common side effects include headache, back pain, and facial flushing.

What Is Tadalafil?

Tadalafil (Cialis^®) is a drug 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). It is available by prescription.

(Please note that this article refers specifically to Cialis, the original tadalafil product that is approved for treating erectile dysfunction and BPH. For information about the tadalafil product used to treat pulmonary arterial hypertension, please see Adcirca.)

Uses of Tadalafil

Tadalafil has been licensed to treat erectile dysfunction (ED). Erectile dysfunction, also known as impotence, can be defined as 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.

How Does It Work?

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