Description
Sildenafil belongs to a group of medications called phosphodiesterase type 5 inhibitors. It is used for the treatment of erectile dysfunction (male impotence). It helps to achieve and keep an erection sufficient for sexual activity. It does this by allowing a greater blood flow into the penis when a man is sexually aroused. It works only with sexual stimulation and does not increase sexual desire.
The usual recommended dose is 50 mg taken as needed, approximately 30 to 60 minutes before sexual activity. However, the medication may be taken any time from 4 hours to half an hour before sexual activity. Based on the effectiveness and side effects of the medication, the dose may be increased to 100 mg or decreased to 25 mg.
The maximum recommended dose is 100 mg and it is not recommended to take more than one dose per day. Sildenafil may be taken with or without food, but taking it with a high-fat meal may increase the time before the medication starts working.
