Viagra - Sildenafil

Viagra is a medicinal drug that relaxes your muscles and increases blood flow to various areas of your body. The drug behind the brand name Viagra is named Sildenafil, and is used to treat erectile dysfunction, also known as impotence. There is another brand of Sildenafil that is used to treat pulmonary arterial hypertension which improves exercise capacity in men and women.

There are other possible uses for Viagra; however it is not listed on this particular guide.

There are many important things to note about using Viagra that may become problematic if not understood. You are not to take Viagra if you are also using a nitrate drug for chest pain or heart related issues. These include nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, and others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket).

Taking Viagra with a nitrate medication will increase your chances of developing low blood pressure which can cause fainting, strokes, or even a heart attack to occur. If you experience dizziness, pain, numbness or a tingling in your chest during sexual activity, stop and call your doctor immediately.

There are certain medications that will affect the potency of Viagra and should be avoided (unless cleared by a medical professional): bosentan, warfarin, cimetidine, erythromycin, doxazosinm, prazosin, Terazosin, HIV medicines, itraconazole, ketoconazole, carbamazepine, Phenobarbital, phenytoin and rifampin to name a few. It is good practice to keep your doctor informed about every drug you take as there may be some that are hazardous to Viagra that may not be mentioned.

Do not take Viagra more than once per day. It is best if you allow 24 hours to pass between doses. If your erection painfully lasts more than 4 hours, you should consult your doctor. It is known that a prolonged erection can cause damage to your penis. Viagra can possibly cause sudden vision loss due to lack of blood flow to the eye. This occurred only in a small sample of people of those who smoke, 50+ years old or have high blood pressure.

STOP taking Viagra if you experience any form of vision loss. It is not confirmed that Viagra has a direct connection with vision loss but it seems more prominent in males over 50 who smoke or have high cholesterol.

Before getting a prescription from your doctor, please notify him/her if you have any of the following pre-existing conditions: Heart Disease, History of Stroke, Heart Attack or Heart Rhythm Disorder, Congestive Heart Failure, High or Low Blood Pressure, Coronary Artery Disease, Liver Disease, Kidney Disease, Blood Cell Disorders, Stomach Ulcers, Eye conditions, Penile deformity and if you’ve been told not to have sex for health reasons. Your doctor will make adjustments to your medications (and sometimes test your body for compatibility) should you posses any of the above conditions.

Taking Viagra is fairly simple. Just take the recommended dosage as described by your doctor as prescribed for you. Never take more medication than instructed as it could be harmful to your body.
