What is the most important information I should know about nitroglycerin?

Do not use nitroglycerin if you are taking sildenafil (Viagra). Serious, life-threatening side effects can occur if you take nitroglycerin while you are using sildenafil.

Nitroglycerin can cause severe headaches, especially when you first start using it. These headaches may gradually become less severe as you continue to use nitroglycerin. Do not stop taking the medication. Ask your doctor before using any headache pain medication.

What is nitroglycerin?

Nitroglycerin is in a group of drugs called nitrates. Nitroglycerin dilates (widens) blood vessels, making it easier for blood to flow through them and easier for the heart to pump.

Nitroglycerin is used to treat or prevent attacks of chest pain (angina).

Nitroglycerin may also be used for other purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking nitroglycerin?

Do not use nitroglycerin if you are taking sildenafil (Viagra). Serious, life-threatening side effects can occur if you take nitroglycerin while you are using sildenafil. You should not use this medication if you are allergic to nitroglycerin, isosorbide mononitrate (Imdur), or isosorbide dinitrate (BiDil, Isordil), or if you have:

early signs of a heart attack (chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, general ill feeling);
severe anemia (a lack of red blood cells); or
a brain injury, hemorrhage, or tumor.

Before taking nitroglycerin, tell your doctor if you are allergic to any drugs, or if you have:

congestive heart failure;
a history of heart attack, stroke, or head injury;
low blood pressure;
glaucoma;
migraine headaches;
liver disease.

If you have any of these conditions, you may need a dose adjustment or special tests to safely take nitroglycerin.
