Q. Who should not take Viagra?
A. You should not take Viagra if you are taking drugs, which contain nitrates such as nitroglycerin (commonly used for chest pains because of heart disease). Taking Viagra with any nitrate medicine can cause your blood pressure to suddenly drop to an unsafe or life-threatening level. You could get dizzy, faint or even have a heart attack or stroke. Nitrates also found in illegally inhaled drugs (including amyl nitrate, nitrite or "poppers," and others) have the same effect when combined with Viagra.
