Who is Viagra for?

Viagra is a popular treatment for men who experience erectile dysfunction (ED). ED is common and can affect men at any point in their life (although the incidence increases in older age) even if they are fit and healthy.

What is Viagra?

Viagra is the most well-known member of a class of medications called phosphodiesterase type 5 (PDE-5) inhibitors. The PDE5 inhibitors, including Viagra, help men to get or maintain a suitably hard penile erection. In response to sexual stimulation, Viagra increases the blood flow to the penis and creates a hard erection ready for sexual intercourse.

Is there a difference between Viagra and Sildenafil?

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".

What is the correct dose to take?

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. 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.

What is the correct way to take it?

The tablet should be swallowed whole with a glass of water approximately one hour before sexual intercourse. Taking the treatment with food can delay the onset of action. 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.

How long does it take Viagra to work?

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).

How long will it last?

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.

What are the risks or side effects of Viagra?

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. For those who do experience side effects, the most common are headache, flushing, indigestion, nasal congestion, nausea, dizziness and visual disturbances. They generally only last a few hours. Viagra should not be taken with any other PD5 inhibitors. It should not be combined with nitrates used in cardiovascular disease, alpha blockers (for high blood pressure) or any recreational drugs. Caution is advised in the use of Viagra in people with diabetes, anatomical deformation of the penis (such as Peyronie’s disease) or a predisposition to painful erections e.g. in sickle cell disease or leukaemia.

Are there alternatives to Viagra?

Although Viagra is the most famous treatment for ED and is effective in most men, there are other PD5 inhibitors. These include Cialis (Tadalafil), Levitra (Verdenafil) and Spedra (Avanafil) and have a slightly faster onset of action. Cialis is often used my men who engage in sexual activity at least three times a week as a daily tablet is available.
