Cialis Side Effects

From Pharmacy Drug Guide

Cialis, a brand name for tadalafil, is primarily used to treat erectile dysfunction or ED in men. ED or impotence means the lack of ability to develop or keep an erection. Cialis is a prescription medication that works by relaxing muscles and increasing blood flow to the penis. It is also approved for ED patients who also have benign prostate hyperplasia.^[1]

As with any medication, some side effects may occur while taking Cialis. In several clinical trials, headaches were the most common side effect. Other adverse reactions include runny or stuffy nose, pain in the back or other areas, and indigestion. Cialis is not recommended for patients with cardiovascular diseases or certain other health problems.^[1]
