Sildenafil

Alternative Names: Viagra

Sildenafil (Viagra) is a medication commonly used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis through inhibition of the enzyme PDE-5, which helps men achieve and maintain an erection when sexually stimulated. The drug is usually taken about 30–60 minutes before sexual activity, and its effects can last up to 4 hours. Common side effects include headache, flushing, nasal congestion, and indigestion; more serious but rare effects include vision or hearing changes and priapism (prolonged erection). Sildenafil should not be used with nitrates (for chest pain) because the combination can cause dangerous drops in blood pressure.

Sildenafil is usually the go-to first-line treatment for erectile dysfunction. It’s been around the longest, so we have a strong track record for both safety and effectiveness. With cheap generics available, it’s often the most affordable option too. Overall, it works well, is generally well tolerated, and is easy to access—though other PDE-5 inhibitors might be a better fit depending on how long you want it to last or how you respond.
