Cialis (tadalafil) (tadalafil) — Uses, Dosage, Side Effects & Safety

Drug class: Phosphodiesterase type 5 (PDE5) inhibitor

Overview

Cialis (tadalafil) is a prescription medication used to treat erectile dysfunction (ED), symptoms of benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension (PAH) in adults. It works by relaxing blood vessels and increasing blood flow to certain areas of the body, which helps men achieve and maintain an erection, and can also relieve urinary symptoms associated with BPH. Cialis is taken orally, usually as a tablet, and can be used either as needed before sexual activity or once daily, depending on the condition being treated. It is important to follow your healthcare provider's instructions for dosing and not to take more than prescribed. Cialis does not protect against sexually transmitted infections and should not be used with certain medications, such as nitrates, due to the risk of dangerous drops in blood pressure.
