Viagra is a medication used to treat erectile dysfunction by improving blood flow to the penis. Viagra keeps working in your body for up to 5 hours. This means that if you’re aroused, you should still be able to get an erection up to 4 hours after taking a dose of Viagra. Even though Viagra keeps working in your body for several hours, your erection shouldn’t last this long. In fact, in rare cases, Viagra can cause priapism (a long-lasting and sometimes painful erection). Priapism is a medical emergency that needs to be treated right away.

Viagra is a type of drug called a phosphodiesterase type 5 (PDE5) inhibitor. It works by inhibiting (blocking) the action of an enzyme called PDE5. (An enzyme is a protein that helps chemical reactions to happen inside your body.) Usually, an erection goes away when PDE5 breaks down the cyclic GMP in your penis.
But Viagra blocks the action of PDE5, so it allows cyclic GMP to keep working for a longer period of time than usual. This action improves blood flow to your penis and helps you get and keep an erection. No, Viagra doesn’t directly increase your sex drive. And it doesn’t make you sexually aroused. However, some people find that if Viagra works to treat their erectile problem, it also increases their sexual confidence.

|---|---|---|---|
| Excessive dosing | Increased side effects, hypotension | Headache, dizziness, flushing | Follow prescribed dose, avoid self-medicating |

| Mixing with alcohol or other drugs | Increased cardiovascular risk, adverse effects | Fainting, chest pain | Avoid alcohol, consult doctor if on other meds |
