Viagra is the most well-known treatment for adult men with erectile dysfunction, sometimes known as impotence. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity. Viagra is one of a class of drugs known as PDE-5 (Phosphodiesterase type 5) inhibitors. Viagra and the other PDE-5 inhibitors can help men with erectile dysfunction (male impotence) by enhancing the erectile response when a man is sexually stimulated.
What is Sildenafil?
Sildenafil citrate is the generic version of the Viagra licensed since 2013 in the UK.
Sildenafil is an effective, modern medicine used to treat erectile dysfunction (ED). When you take Sildenafil you may be able to:
- Improve your ability to get and maintain an erection

What is the difference between Viagra and Sildenafil?
Sildenafil citrate is the active ingredient in Viagra and is available in a generic, unbranded tablet. Sildenafil and Viagra are medically equivalent but Sildenafil is available at a much lower cost.
Generic medicines contain the same active ingredient and are equally effective and medically equivalent as the branded products but are available at a lower price. Generic manufacturers have to demonstrate that they are medically identical to the branded product – i.e. they offer the same quality, strength, stability and effectiveness.
Generic medicines are required meet the same standards of safety, quality and efficacy as the branded medication. To receive market approval from the European Medicines Agency and MHRA, a generic medicine must be ‘bioequivalent’ to the originator product.
Choosing the Correct Dosage
The recommended starting dose for Viagra (sildenafil) is one 50mg tablet taken 1 hour before sexual activity. If you achieve the desired effect but are suffering from side effects, try lowering the dose to 25mg. If after trying 50mg tablets four times without the desired effect, and you are not experiencing side effects, increase the dose to 100mg. If after trying 100mg 8 separate times without effect you should cease treatment and consult your doctor. You should not take Viagra (sildenafil) more than once a day as this will have not increase the effectiveness and may increase the likelihood of experiencing side effects.
How To Take
You should take Viagra (Sildenafil) about one hour before you plan to have sex. Swallow the tablet whole with a glass of water.
Viagra (Sildenafil) can be taken with or without food. However, you may find that Viagra (Sildenafil) takes longer to start working if you take it with a heavy meal.

How long does Viagra Last?
Viagra will stay in the body on average 4 hours after dosing. For some men it may remain as long as 5 hours, or a few as 3 hours.
Side Effects of Viagra
Viagra is generally well tolerated and comes in a variety of dosages so the strength can easily be decreased for men experiencing bothersome side effects. The most common side effects include headache, flushing, indigestion, nasal congestion, dizziness, nausea, hot flush and visual disturbances. These common side effects are all transient in nature and should not last more than a few hours. Studies have not shown any effect on sperm motility or morphology.
How Long Does Viagra Take To Work?
When taken on an empty stomach, Viagra is absorbed relatively rapidly and it will usually work within 30-60 minutes, although it may take up to 120 minutes in a small percentage of men. Taking Viagra with food will decrease the rate of absorption and can significantly increase the time taken for Viagra to work.
Viagra comes in three different strengths: 25mg, 50mg and 100mg. The recommended starting dose for first time users is 50mg. The dose can then be increased to 100mg if 50mg is not strong enough. For men who experience bothersome side effects the dose can be reduced to 25mg. Only one tablet should be taken in each 24 hour period.

Viagra was patented by Pfizer in 1996 and released onto the market a couple of years later. As a result, it has been safely used by millions of men around the world who have erectile dysfunction.
Viagra and Alcohol
Clinical trials of healthy men taking Sildenafil 50mg did not show further decreases in blood pressure when taken with moderate amounts of alcohol. However, alcohol by itself has the ability to increase erection difficulties.
Alternatives to Viagra
Clinical trials have shown that for 84% of men Viagra helped to improve their erections. For those who find Viagra less effective than hoped, or for whom planned dosing is difficult, there are other PDE5 inhibitors available in tablet form. These medications include Cialis (Tadalafil), Levitra (Verdenafil) and Spedra (Avanafil). These three medications have a slightly faster onset of action than Viagra. Cialis also has a daily tablet for those engaging in sexual activity at least three times each week.
