Generic name: nitroglycerin (sublingual) (NYE troe GLI ser in (OR al/sub LIN gwal))
Brand name: Nitrostate
Drug class: Antianginal agents, Vasodilators
Nitrostat (nitroglycerin) is a nitrate that dilates (widens) blood vessels, making it easier for blood to flow through them and easier for the heart to pump.
Nitrostat sublingual tablets are used to treat a type of chest pain called angina.
Angina is a pain or discomfort that keeps coming back when part of your heart does not get enough blood. Angina feels like a pressing or squeezing pain, usually in your chest under the breastbone. Sometimes you can feel it in your shoulders, arms, neck, jaws, or back. Nitrostat can relieve this pain.
Nitrostat is a white, round, flat-faced tablet available in 3 strengths. 0.3 mg, 0.4 mg, and 0.6 mg.
You should not use Nitrostat if you are also using medicine to treat pulmonary arterial hypertension (PAH). Do not take erectile dysfunction medicine (Viagra, Cialis, Levitra and others) while you are using Nitrostat.
You should not use sublingual Nitrostat if you have severe anemia, increased pressure inside your skull, circulation problems, chest pain that spreads to your jaw or shoulder, or signs of shock (pale skin, suddenly feeling light-headed).
Seek emergency medical attention if you have early symptoms of a heart attack (chest pain or pressure, pain spreading to your jaw or shoulder, sweating, general ill feeling).
Get emergency medical help if you still have chest pain after using a total of 3 doses in 15 minutes, or if you have chest pain that seems unusual.
