What Is Sildenafil (Viagra)?

Sildenafil 25/50/100mg, commonly known as Viagra, is a medicine used to treat erectile dysfunction (ED) in men. It helps men achieve and maintain an erection when sexually aroused. It comes in different strengths: 25mg, 50mg, and 100mg.

How Does Sildenafil Work?

Sildenafil works by increasing blood flow to the penis, helping men get an erection when sexually stimulated. It does not cause an erection on its own—sexual arousal is still needed.

Who Can Take Sildenafil?

Sildenafil is suitable for men who have difficulty achieving or maintaining an erection. It is often recommended for those with erectile dysfunction caused by stress, medical conditions, or poor blood circulation.

How to Take Sildenafil

• Take one tablet about 30–60 minutes before sex.
• It can work for up to 4–6 hours.
• Do not take more than one tablet per day.
• Swallow the tablet with water, with or without food. (A heavy meal may slow its effect.)

Possible Side Effects

Most men tolerate Sildenafil well, but some may experience:

• Headache
• Flushing (warm feeling in the face)
• Dizziness
• Indigestion
• Nasal congestion

Rare but serious side effects include vision changes, chest pain, or a prolonged erection (lasting more than 4 hours). If these happen, seek medical help immediately.

Precautions & Warnings

• Do not take Sildenafil if you use nitrate medications for heart problems.
• Avoid alcohol, as it can reduce the medicine’s effectiveness.
• Consult a doctor if you have heart disease, high blood pressure, or liver problems.
• Sildenafil is not for women or children.

Conclusion

Sildenafil (Viagra) is an effective treatment for erectile dysfunction, helping men improve their sexual performance. It works by increasing blood flow to the penis but requires sexual stimulation to be effective. Always follow the recommended dose and consult a doctor if needed.
