Cenforce 200mg which contains the active ingredient sildenafil citrate, typically lasts 4 to 6 hours after consumption. Its effects begin within 30 to 60 minutes of taking the tablet, especially when taken on an empty stomach. While the duration may vary depending on individual factors like metabolism, age, and overall health, the peak effect is usually experienced within the first 2 to 3 hours. However, Cenforce 200 does not cause continuous erections; sexual stimulation is required for it to work. Avoid taking more than one dose in 24 hours to prevent potential side effects.
