How Long Does Sildenafil Stay in Your System?
Sildenafil typically stays active in your body for 4–6 hours, though traces can remain up to 24 hours. It doesn’t mean you’ll have an erection the entire time—only that it’s easier to get one during that window with arousal.
Need-to-Know Tips:
- Peak effectiveness: 1–2 hours after taking
- Metabolized by the liver
- Longer effects in older men or those with kidney issues
