What does sildenafil do for a man?

Sildenafil is a medication primarily used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, making it easier to achieve and maintain an erection during sexual stimulation.

Here's how it helps:

• Relaxes blood vessels in the penis by inhibiting an enzyme called PDE5

• Allows for stronger and longer-lasting erections

• Improves sexual performance and confidence

It usually starts working within 30 to 60 minutes and can last for up to 4–6 hours. Sildenafil is also used in lower doses under different brand names to treat pulmonary arterial hypertension (PAH) by improving blood flow in the lungs.
