➨ Cenforce 150 mg tablets, containing sildenafil citrate, typically lasts for about 4 to 6 hours after it is taken, providing a sustained window of effectiveness for achieving and maintaining an erection during sexual activity. The effects of Cenforce usually begin within 30 to 60 minutes after consumption, depending on factors such as an individual’s metabolism, age, and whether it was taken on an empty stomach. Although the primary effects last several hours, traces of the medication remain in the body longer, so it is advised to avoid taking more than one dose in a 24-hour period to ensure safety.
