Cialis, containing the active ingredient Tadalafil, is a medication commonly prescribed for erectile dysfunction. It is also used to alleviate symptoms of benign prostatic hyperplasia and in certain cases to treat pulmonary arterial hypertension at varying doses and under different trade names.
The drug works by relaxing blood vessels and increasing blood flow to particular areas of the body. This effect may lead to some side effects, generally mild and temporary, but occasionally requiring urgent medical attention.

These symptoms often resolve within a few hours or days as treatment continues or once the dose effect subsides.
