Typically, one tablet of Sildenafil is recommended to be taken on an empty stomach approximately 60 minutes before sexual activity. The tablet should be swallowed whole, and not broken or crushed.
Sildenafil typically starts working in about 30 minutes, but its peak effect begins for most men about 60 minutes after it’s taken on an empty stomach. Keep in mind that food in the stomach can delay the absorption of Sildenafil by up to an hour, and also that the timing of each individual’s response is a little bit different.
Remember that Sildenafil will only work when you are sexually aroused, but it should help to improve climax control while the medication is active in your system.
Sildenafil typically lasts for at least 4 hours and up to 8-12 hours, but its effect is strongest 2-4 hours after it’s taken. As the amount of Sildenafil in the bloodstream drops, so do the effects.
