Nitrostat (generic: nitroglycerin) is a prescription medication used to treat or prevent episodes of angina (sudden chest pain). Nitrostat belongs to a group of drugs called nitrates which work by relaxing (widening) blood vessels making it easier for the heart to pump blood.

This medication comes in tablet form to be dissolved under the tongue or between the cheek and gum at the first sign of chest pain. The dose may be repeated every 5 minutes until chest pain is relieved. Seek emergency medical attention if the pain persists after 3 doses.

Common side effects of Nitrostat include headache, dizziness, and weakness.
