Viagra Facts

ViagraR is the brand name for a prescribed medication used in the treatment of erectile dysfunction in men. The drug works by increasing blood flow to the penis, which helps men achieve an erection and maintain it during sexual activity. There are, however, various Viagra facts such as side effects and drug interactions that men should know before taking this medication.

Viagra side effects

Most prescriptions are labeled with possible side effects and Viagra is no exception. According to Pfizer, the makers of Viagra, the most common side effects reported for Viagra include headache, facial flushing and upset stomach. Some prescribed patients may experience vision problems, including light sensitivity or blurred vision. While hearing and/or vision loss may occur, it is unknown if these problems are directly related to Viagra or the result of other factors.

General precautions while taking Viagra

Along with the side effects there are also numerous warnings to men as to who should not take the drug. Drugs.com warns that men who take nitrates should avoid taking Viagra. Men who use recreational drugs that contain butyl or amyl nitrate should also not take Viagra. These recreational drugs are more commonly known as "poppers" but are generally labeled with product names such as REDS and RUSH.

Although men who take nitrates for heart conditions are warned against taking Viagra, Pfizer does state that their medication is safe for men who have high blood pressure and heart disease. Men who have kidney conditions or older men may be prescribed Viagra at lower dosages. According to information released by Pfizer Labs there is no safety or efficacy data available for men who have suffered a myocardial infarction, stroke or life-threatening arrhythmia within the last six months. The safety of Viagra use in men with bleeding disorders or active peptic ulceration is also unknown, and Viagra should not be used in conjunction with other erectile dysfunction medications.

Getting results with Viagra

Pfizer offers several recommendations so that Viagra users can get the best results from their medication; these recommendations include relaxing and eating right. Fatty foods may hinder the body's ability to absorb the medication properly, so avoiding these types of foods is important. Alcohol consumption does not have to be avoided while taking Viagra; however, it will not improve the drug's performance either.

To achieve better results, men should take the time to get into the mood for sexual activity. Contrary to what some believe, Viagra does not cause an immediate erection, and it does not increase sexual drive. Viagra is not an aphrodisiac; men still need sexual arousal in order to get an erection while taking Viagra. After taking the medication, the drug can take as little as 15 minutes to begin working or up to an hour.

When to see the doctor while taking Viagra

Men who are taking Viagra should contact their doctor should they experience any side effects or anything out of the ordinary after taking the medication. Infrequent reports of erections lasting longer than four hours and priapism (painful erections) have occurred in men taking Viagra. Should this occur, Pfizer Labs recommends seeking immediate medical attention as untreated priapism can lead to permanent penile damage.
