Overview

Viagra is a prescription medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors.

Here are some key points about Viagra:

– Erectile Dysfunction: Viagra is primarily used to help men achieve and maintain an erection sufficient for sexual activity. It works by increasing blood flow to the penis when a man is sexually stimulated.
– Dosage: Viagra comes in different doses, and the recommended starting dose is usually 50mg. The dosage can be adjusted based on individual response and tolerability, but it’s important to follow the doctor’s instructions.
– Timing: Viagra is typically taken about 30 minutes to 1 hour before sexual activity, but the timing can vary based on individual factors. It should not be taken more than once a day.
– Side Effects: Common side effects of Viagra may include headaches, flushing, indigestion, and nasal congestion. In rare cases, serious side effects such as priapism (prolonged erection) can occur and require immediate medical attention.
– Interactions: Viagra can interact with certain medications, especially nitrates used for chest pain, and should not be taken with them. It’s important to inform your healthcare provider about all medications you are taking.
– Precautions: Viagra should not be used by men who are allergic to sildenafil or have certain medical conditions like heart problems. It’s important to discuss your medical history with a healthcare provider before using Viagra.
