Viagra was initially created for men who suffer from erectile dysfunction. It enables a man to attain and sustain an erection during sexual intercourse. Many men have thought of buying Viagra but there are pieces of information that are not very clear to them about it. Some people think that the drug is so expensive that they cannot afford to purchase but according to the researchers, FDA has no control over its cost. Viagra’ cost can also be covered by insurance since FDA has no control over that as well.
Generally, increase in the blood flow is what leads to an erection and if your penile blood vessels cannot do that, you will find it difficult to have sex or to erect even when you are sexually stimulated.
Viagra works by offering the effect that is produced by some chemical substances released into the penile tissues together with the sexual arousal. This allows more blood to flow into the penis and cause an erection. Viagra is taken orally at least an hour before sexual intercourse. This drug should be taken only once a day. The drug is sold as oral tablets that come in different forms such as one 100 mg, 25 mg, and 50 mg. When buying Viagra, you have to present a prescription since it is a strong drug that must be used strictly as prescribed by a doctor.
All drugs have side effects that come differently to different people, and the same implies to Viagra. The common side effects of Viagra include visual problems, headaches, stomach aches and dizziness. The side effects should not last for a very long period of time therefore when you become dizzy, feel nausea, have pain or when you feel a tingling in your neck region, chest, arms or in your jaws when having sex, you should stop immediately and call your doctor. Viagra should not be combined with other impotency treatments as some of the drugs may interfere with its effectiveness or may lead to very serious health conditions.
Apart from impotency drugs, Viagra should not be taken together with other medications and if you want to do so, it is advised that you consult your doctor no matter what kind of drug you are taking. By doing so, you will get the best advice from a qualified professional. It is important to realize that Viagra should not be taken with drugs that contain nitrates. For example, the patients who are taking nitroglycerin should not take Viagra because it can lower their blood pressure tremendously. Though some women use Viagra to increase their sex libido, it is not approved for them therefore a woman should not take Viagra. Also old men who are above sixty five years of age should not take Viagra unless they tolerate it in very small quantity, especially the ones who are sensitive to its effects.
Any concept of missed dose is not important because Viagra can be taken when needed at any time so long as it is not overused.
