Description

 

Tadalafil is a PDE5 inhibitor, currently marketed in pill form for treating erectile dysfunction (ED) for the treatment of pulmonary arterial hypertension. It initially was developed by the biotechnology company ICOS. The most common side effects when using tadalafil are headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose. These side effects reflect the ability of PDE5 inhibition to vasodilate (cause blood vessels to widen) and usually go away after a few hours. Back pain and muscle aches can occur 12 to 24 hours after taking the drug, and the symptom usually disappears after 48 hours.
