How sildenafil works
The sildenafil rundown
Stronger erections by blocking an enzyme called PDE5
Sildenafil blocks an enzyme called PDE5, which makes it easier for blood to flow to the penis for a stronger, longer lasting erection.
Lasts 4-6 hours
Sildenafil stays in the body for 4-6 hours, during which time a person has an easier time getting and maintaining an erection. But don’t worry, it doesn’t cause arousal, so you’ll only get erect when you’re in the mood. That means when the time is right, turn up the romance.
Sildenafil is an ED medication that’s taken orally as needed. When used as directed, it works within 30-60 minutes, so you’ll be ready for sex when the mood strikes.

How to use sildenafil
Take an hour before sex
For best results, take sildenafil (Generic Viagra) 30-60 minutes before sex because your body needs a little bit of time to absorb the medication.
Take on an empty stomach
Two things can lead to sildenafil being not as effective as it should. Taking it too close to the time you plan to have sex may make it more difficult to get a strong erection. Plus, if you eat a high-fat meal right before, it can take away from sildenafil's effectiveness. Taking sildenafil on an empty stomach can maximize its effects.
Skip the alcohol for best results
To get the best results, only drink alcohol moderately when you're about to take sildenafil. That means fewer than two drinks per day (one drink is equivalent to a 5oz glass of wine, a 12oz glass of beer or a 1.4 oz shot).
Sildenafil side effects
The most common side effects include:
What safety information should I know before taking sildenafil?
Do not take sildenafil if you take any medicines called nitrates, often prescribed for chest pain, or guanylate cyclase stimulators like Adempas (riociguat) as this can result in a sudden, dangerous drop in blood pressure. Learn more
