Sildenafil typically lasts for about 4 to 6 hours, depending on individual response and dosage. Medications like Cenforce 100 online, Cenforce 150 mg, and Cenforce 200 mg, which contain sildenafil, provide similar duration of effects. These options are designed to improve circulation and support reliable results for several hours, allowing flexibility. Factors such as metabolism, overall health, and whether it’s taken on an empty stomach can also influence how long sildenafil remains effective
