Viagra: Uses, Benefits, Side Effects, and Important Information for Men

What is Viagra?

Viagra, also known by its generic name sildenafil citrate, is one of the most well-known medications for treating erectile dysfunction (ED) in men. Approved by the FDA in 1998, Viagra works by improving blood flow to the penis, making it easier for men to achieve and maintain an erection during sexual activity.

How Viagra Works

Erectile dysfunction occurs when there is not enough blood flow to the penis. Viagra is part of a class of medications called PDE5 inhibitors, which relax blood vessels and allow increased blood flow.

• Works within 30 to 60 minutes of taking it.
• Effects may last up to 4–6 hours.
• Requires sexual stimulation to be effective (it does not cause an automatic erection).

Benefits of Viagra

• Improves sexual performance by helping achieve and sustain erections.
• Boosts confidence and relationships, as ED can cause stress and anxiety.
• Well-studied and trusted worldwide with millions of users since its approval.

Dosage and How to Take Viagra

• Usually prescribed in 25 mg, 50 mg, or 100 mg tablets.
• Most men start with a 50 mg dose, taken about 1 hour before sexual activity.
• Do not take more than once per day.
• Avoid high-fat meals and excessive alcohol before taking Viagra, as they may reduce effectiveness.

👉 Always follow your doctor’s advice for safe and effective use.

Possible Side Effects of Viagra

Like any medication, Viagra can cause side effects. Common ones include:

• Headache
• Flushing (redness in face/neck)
• Indigestion

• Nasal congestion
• Vision changes (blurred or blue-tinted vision)

⚠️ Seek medical help immediately if you experience chest pain, sudden vision loss, or an erection lasting longer than 4 hours (priapism).

Who Should Avoid Viagra?

Viagra is not safe for everyone. Avoid Viagra if you:

• Take nitrate medications (for chest pain/heart problems).
• Have severe heart disease or uncontrolled blood pressure.
• Have certain eye conditions (retinitis pigmentosa).
• Have been advised by a doctor to avoid sexual activity.

Can You Buy Viagra Online in the USA?
