If you have heart disease (eg angina pectoris "chest pain") and you are being treated with medicines that contain nitrates, or substances which release nitric oxide (eg molsidomine, nitroglycerin or similar substances), you should in any case take sildenafil (Viagra). Take Viagra at the same time that these drugs may enhance their effect dangerously and cause a voltage drop or circulatory collapse. If you take a drug like this, talk to your doctor. If you're not sure, ask your doctor or pharmacist. For the above reasons (risk of dangerous interaction with Viagra), you must not take any "poppers" sold illegally (which contain amyl nitrite as the active ingredient). If you take Viagra, taking medicines containing nitrates or substances which release nitric oxide (eg molsidomine, nitroglycerin or similar substances) is strictly prohibited. This also applies in case of sudden onset of heart problems (such as chest pain, angina pectoris). This type of medical emergency requires that you (or your partner / close) do know all the people who treat you that you have taken Viagra. Anyway, you should immediately contact your doctor. Alone can decide what to do. Do not take Viagra if you have ever had an allergic reaction to Viagra or one of its components listed under "Composition". An allergic reaction can manifest as a rash, itching, congestion of the face, swollen lips or shortness of breath. In this case, let your doctor know. Viagra should not be administered to children or adolescents under 18 years.

Why is Viagra Prescribed
Men Up to 65 Years of Age - Viagra 50mg is prescribed to be taken once a day, 30 minutes to 4 hours before intercourse. In situations where 50mg isn't effective, your doctor may prescribe 100mg to be taken once daily 30 minutes to 4 hours before intercourse.
For Men Older than 65 Years of Age - Viagra 25mg is prescribed to be taken 30 minutes to 4 hours before intercourse. In some circumstances, men older then 65 may have their doses increased.
Very few drugs work perfectly, and Viagra® is no exception. Just about every drug has side effects that arise because the drug is flowing throughout the body and may affect parts of the body unintentionally. For example, aspirin is a drug that relieves pain, but this same drug can also erode the stomach lining and thin the blood. Those are side effects of aspirin.
The first problem comes because Viagra happens to have a spillover effect. It blocks PDE5, but it also has an effect on PDE6. It turns out that PDE6 is used in the cone cells in the retina, so Viagra can have an effect on color vision. Many people who take Viagra notice a change in the way they perceive green and blue colors, or they see the world with a bluish tinge for several hours. For this reason, pilots cannot take Viagra within 12 hours of a flight.
The second problem comes for people who are taking drugs like nitroglycerin for angina. Nitroglycerin works by increasing nitric oxide, and it helps with angina by opening up the arteries that supply the heart with oxygen. If you take nitroglycerin and Viagra together, the increased nitric oxide plus the blocking of PDE5 can lead to problems.
Other problems with Viagra can include little things like headaches (the drug, as a side effect in some men, opens up arteries in the brain's lining and causes excess pressure) and big things like heart attacks. The possibility of heart attacks is one reason why Viagra is a prescription drug rather than an over-the-counter drug like aspirin. A doctor needs to understand your medical history and make sure that Viagra won't cause a heart attack. Occasional patients who take Viagra get painful, long-lasting erections and have to see a doctor to solve the problem.
Finally, there is some concern that some men, especially younger men who take Viagra recreationally and who don't really need it for physical reasons, may end up with a dependency on the drug. That is, they may become unable to maintain an erection without taking Viagra.
