Viagra: What you should know before you take that plunge.

Viagra, the citrate salt of sildenafil, is very popular because of its high success rate in the treatment of erectile dysfunction. The convenience of administration and the proliferation of internet sites that offer Viagra tablets for sale at bargain prices have brought about a greater interest not only amongst men with ED problems, but men who want to improve their sex lives. However, apart from the drug being wrongly taken as a cure-all for the various sexual dysfunctional problems (Viagra is strictly an erectile dysfunction medication, and does not work for other sexual dysfunction) there are other issues associated with taking the drugs.
Viagra is a prescription drug, and like every other precaution drugs should be taken after due consultation with a qualified doctor. Before you Buy Viagra online cheap, always have in mind that there are medicines which can alter how Viagra works. Let your doctor inform you on the kind of drugs that interfere with the mode of action of Viagra. Let him know if you are taking any drugs, prescription or non-prescription. As a rule of thumb, Viagra should not be combined with nitrates-containing drugs. Any drug known as alpha-blocker, i.e. drugs taken for the treatment of prostrate problems or high blood pressure, have been found out to work in synergism with Viagra to lower the blood pressure, which could result in dizziness or syncope. When taking protease inhibitors like anti-retroviral drugs, there is the possibility that the dose you would be given could be adjusted. Also, Viagra should not be used in combination with other erectile dysfunction therapies, which could be in form of pills or drugs that could be injected or inserted into the penis.
When you want to buy Viagra online no prescription, knowing the right dosage to purchase is important. Viagra is available in different doses of 25mg, 50mg, and 100mg. And due to variations in our body physiological needs, different pills work for different people. It is possible that the pill you take may not produce the results you desire. Before you increase your dose, however, consult your doctor, and working together with you can help him know the best dose for you. When you are taken the drug on prescription, always ensure that you do not exceed your dose, and it should be taken once daily. An overdose of the drug could pose a great danger.
There are certain situations that may warrant your doctor prescribing Viagra for you in lower doses. For instance, if you are in your late sixties or you have serious kidney or liver problems, the likelihood that your doctor would want to start you off on the lowest dose of 25mg is high.
Usually, when you want to take Viagra, it should be about an hour before sex. Any meal that has a high fatty content – French fries, Cheeseburger, etc – usually reduces the absorption rate of the drug, and it could take a while for the effect of the drug to be felt after the consumption of such meal. It is noteworthy to always bear in mind that this drug only works when you are stimulated sexually; just by taking the drug will not cause an erection.
Still on the Viagra issue, even after taking all the necessary precautions, Sildenafil can still cause some side effects, like every other drug. Usually, these side effects could be mild to moderate and don’t usually persist for long. Common side effects associated with the drug are facial flushing, headache, stomach upset, and to a less extent vision colouration and blurring. In very rare cases, incidences of people who have taken PDE5 inhibitors – oral ED medicine, including Viagra – have reported loss of vision in one or both eyes.
