💊 Viagra
Viagra is a prescription medicine used mainly to treat erectile dysfunction (ED)—difficulty getting or maintaining an erection. Its active ingredient is sildenafil.
❤️ How it works
Viagra works by:
- Relaxing blood vessels
- Increasing blood flow to certain areas of the body
- Helping achieve an erection only when sexually stimulated
It does not increase sexual desire.
⏱️ How it’s used
- Taken about 30–60 minutes before sexual activity
- Effects can last 4–6 hours
- Should not be taken more than once in 24 hours (unless doctor advises otherwise)
⚠️ Common side effects
- Headache
- Flushing (warm/red face)
- Nasal congestion
- Dizziness
- Upset stomach
- Mild vision changes (blue tint in vision in some cases)
🚨 Serious risks (important)
Seek medical help if:
- Chest pain occurs
- Erection lasts more than 4 hours (priapism)
- Severe dizziness or fainting
❗ Dangerous interactions
- Never combine with nitrate heart medications (can cause dangerous blood pressure drop)
🧠 Important facts
- It only works with sexual stimulation
- It does not cure ED permanently
- Underlying causes of ED can include diabetes, stress, or heart disease

🧾 Bottom line
Viagra is an effective, well-studied medication for ED, but it must be used carefully and under medical supervision due to heart and blood pressure interactions.
