Viagra (Sildenafil) – Uses, Benefits, Safety Information & Medication Guide

Viagra is the brand name for sildenafil, a prescription medication used primarily for the treatment of erectile dysfunction (ED) in adult men. It belongs to a class of medicines called phosphodiesterase type 5 (PDE5) inhibitors, which work by improving blood flow to the penis during sexual stimulation.

Sildenafil helps many men with ED achieve and maintain an erection when medically appropriate. It does not increase sexual desire, does not prevent sexually transmitted infections, and requires sexual stimulation to work.

Because Viagra is a prescription medication, it should be used according to the guidance of a qualified healthcare professional.
