💊 Viagra pills
Viagra is a prescription medicine used to treat erectile dysfunction (ED) in men, meaning difficulty getting or maintaining an erection.
Its active ingredient is sildenafil, which improves blood flow to the penis during sexual stimulation.
🧠 How it works
Viagra works by:
- Relaxing blood vessels
- Increasing blood flow to the penis
- Helping achieve an erection only when sexually aroused
👉 It does NOT cause automatic erections.
⏱️ How fast it works
- Starts working: ~30–60 minutes
- Duration: about 4–6 hours
⚠️ Common side effects
- Headache
- Flushing (warm face)
- Nasal congestion
- Dizziness
- Upset stomach
- Blurred vision (sometimes blue tint)
🚨 Serious risks (rare but important)
- Chest pain
- Severe drop in blood pressure
- Vision or hearing loss
- Priapism (erection lasting >4 hours — emergency)
❌ Who should NOT use Viagra
- People taking nitrates for chest pain
- Severe heart disease (without doctor approval)

💡 Important safety note
Viagra is prescription-only in most countries because it can interact dangerously with heart medications.
