How long does Viagra last?

Viagra typically lasts for 4 hours in most people, though its effects are strongest in the first 2-3 hours and can sometimes continue up to 6 hours or more depending on individual factors. It starts working 30-60 minutes after taking it on an empty stomach, so take it about an hour before sex. The exact duration varies by person due to factors like age, dose, diet, and metabolism.

Key points:

• Viagra's effects peak around 30-60 minutes after taking it.
• It remains effective for up to 4 hours, but may last 4-6 hours or longer in some cases.
• Duration varies by dose, age, weight, diet, and metabolism.
• Do not take more than one dose in 24 hours.
