Do I need a prescription for nitroglycerin?
Nitroglycerin ointment is used to prevent chest pain (angina) in people with a certain heart condition (coronary artery disease). This medication belongs to a class of drugs known as nitrates. Angina occurs when the heart muscle is not getting enough blood. This drug works by relaxing and widening blood vessels so blood can flow more easily to the heart.This medication will not relieve chest pain once it occurs. It is also not intended to be used just before physical activities (such as exercise, sexual activity) to prevent chest pain. Other medications may be needed in these situations. Consult your doctor for more details.
