Generic Viagra is a drug used for erectile dysfunctions, or male impotence, and it represents the name for a substance known as sildenafil citrate. The substance is the same, while the market name of the drug may vary and so may its price. Generic versions for many types of drugs have been around for quite some time, but Generic Viagra is a fairly new drug on the market, and it gives men a chance at treating their erectile dysfunctions in an affordable way. Generic Viagra can be expected to have the same effects that the brand name Viagra does, because both drugs have the same active ingredient. Therefore, if your doctor has decided that Viagra is safe for you, it means that you can also use Generic Viagra.

How does Generic Viagra work? It increases your ability to have and sustain an erection by inhibiting the enzymes that degrade the cyclic guanosine monophosphate, a substance that facilitates the influx of blood into the penis, by relaxing its spongy tissue. In other words, Viagra dilates blood vessels in the penis, and allows the necessary inflow of blood that an erection requires.

Viagra can cause erections only when a man is sexually excited. This is the reason why this drug is not for regular use. It should be taken about one hour before sexual activity, and once the sexual intercourse is over the erection goes away. The efficacy of Generic Viagra has been evaluated based on self-assessment questionnaires, and this evaluation has shown that this drug is responsible for the sexual function improvement of almost ninety percent of those who have used it to treat their erectile dysfunctions. The evaluation included firmness, frequency, and ability to maintain an erection; level and frequency of desire; frequency of orgasm; sexual intercourse satisfaction; and relationship satisfaction.

When it comes to the side effects that Generic Viagra can have, it is difficult to anticipate them. Your doctor should be informed shortly after the development of a side effect has occurred, or it has changed its intensity. Some of the side effects of Generic Viagra that are more likely to be experienced by those who use it as treatment include headache, abnormal vision, diarrhea, indigestion, urinary tract infection, and nasal congestion. There are other possible side effects, but these have been experienced at a considerably lower frequency. Remember that it is hard to predict how your body will react to this drug. Chances are that you'll be just fine, if you don't have a preexisting condition, such as a heart problem. However, you should inform your doctor about any modification that may occur, and he/she will tell you whether or not you should keep taking Generic Viagra.

It is the doctor once again that will give you the most detailed information about the food and drugs Generic Viagra interacts with. It is a well-known fact that erectile dysfunction drugs should not be used simultaneously unless prescribed by a doctor. However, Generic Viagra may interact with other drugs as well, which is why you have to consult with your doctor before taking this medicine. He or she will also inform you about the special warnings that come with this medication, and what conditions do not allow the use of Generic Viagra.
