Nitroglycerin Key Facts
What dosages is Nitroglycerin available in?
Nitroglycerin is available as 0.3 mg; 0.4 mg; 0.6 mg sublingual tablet.
What is Nitroglycerin used for?
Nitroglycerin is a nitrate that is used for the prevention and treatment of angina (chest pain due to tight blood vessels in the heart).
How does Nitroglycerin work?
Nitroglycerin is a nitrate. This medication causes the blood vessels in your heart to open up (dilate). This helps blood reach the heart better. More blood flow to the heart puts less stress on the heart and relieves heart-related chest pain.

Nitroglycerin is typically taken as one tablet (0.3 mg, 0.4 mg, or 0.6 mg) at the first sign of chest pain. You can take another dose every 5 minutes as needed if you aren’t getting any relief. But don’t take more than 3 tablets in a 15-minute period; get medical help if you still have chest pain.
