Systematic review of randomised controlled trials of sildenafil (Viagra) in the treatment of male erectile dysfunction

In response to sexual stimulation, Viagra increases the blood flow to the penis and creates a hard erection ready for sexual intercourse. Sildenafil Citrate is the active ingredient in Viagra and as such the generically labelled Sildenafil is medically equivalent to Viagra. Sildenafil is equally effective and subject to the same rigorous safety and quality standards as Viagra, but available at a lower price because it is “unbranded”. The dose of Viagra is usually 50 mg taken approximately 1 hour before sexual activity. Some men may find this dose effective, but experience unwanted side effects, in which case 25 mg may be adequate in the future. If 50 mg proves ineffective on four separate occasions and there are no unwanted side effects, then the dose can be increased to 100 mg.

If 50 mg proves ineffective on four separate occasions and there are no unwanted side effects, then the dose can be increased to 100 mg. In the unlikely event of 100 mg being ineffective on 8 separate occasions then you should make an appointment with your doctor for further evaluation.

Stimulation increases blood flow

Only one treatment should be taken per day (24 hour period); taking it more often increases the risk of side effects and does not make it more effective. Viagra is absorbed rapidly (when taken on an empty stomach) and starts to work in most men within 30 – 60 minutes (up to 120 minutes in a minority of men or if taken with a large meal). Viagra will remain in the body for approximately 4 hours, with the range between men being usually 3 – 5 hours. This does not mean you will have an erection for this long, but as it works in response to sexual stimulation, this is the timeframe it is likely to be effective. Viagra is generally very well tolerated by most men and the variety of available doses enables men to titrate the treatment to effect without unwanted side effects.
