What It's For & How To Take

Sildenafil is used to treat erectile dysfunction, sometimes called ED. While taking this medication, if there is no sexual stimulation, there will be little to no effect. If there is sexual stimulation, there will be an increased likelihood of having an erection.

Take sildenafil between 30 minutes to 4 hours before sexual activity. Best results are when you take this medication one hour before sexual activity. Do not take sildenafil with a fatty meal because it will decrease the results.

Do not take more than one tablet in 24 hours. If this medication does not work for you, talk with your doctor. Sildenafil is available in different doses, and your dose may need to be changed.
