Viagra can also be used for other purposes, including treatment for pulmonary arterial hypertension, altitude sickness, as a sports enhancer, and also to help prolong plant life and prevent wilting. Although these are much less common uses.

The active ingredient in Viagra is Sildenafil citrate, and it is manufactured and produced by Pfizer. It is considered to be a very safe drug to use. However, some people do experience side effects. Most of the side effects are very mild however there are a few more serious side effects that are quite rare. Most people don't experience side effects from using Viagra.

Like with most drugs there are opportunities to purchase them cheaper on the internet. One of the best ways to find cheap Viagra online is by purchasing a generic version of the medication. Once the patent on a drug has expired (usually after 20 years) other pharmaceutical companies are then allowed to manufacture and sell a replica or similar version of the original drug as a generic medicine. These are usually significantly cheaper than the original version and are just as potent and they must adhere to all the same strict testing that the originals must go through. The reason why they are so much cheaper is because the pharmaceutical companies don't need to pay for all the original research and development which is the most expensive part of the process.

Over fifty per cent of Viagra users choose to purchase a generic version of the drug, as original branded Viagra is usually very expensive. There are lots of websites online selling both original and generic Viagra tablets at discount prices. But beware of any website offering drastically cheap drugs as these are often scams. Either they will send you a dodgy version of the drug that is potentially lethal, or you may not receive anything for your money at all. The best way to ensure that the website you are purchasing from is legitimate is by making sure they ask you for your prescription details. It is illegal to sell and buy prescription drugs without a valid prescription.
