GoNitro (nitroglycerin) sublingual powder is a nitrate vasodilator used for acute relief of angina or to help prevent angina (chest pain). To use at the onset of an attack, place the granules from 1 or 2 packets (400 mcg each) under your tongue. One additional packet of granules may be used under the tongue every 5 minutes as needed, but no more than 3 packets (1200 mcg) within a 15 minute period.

Seek immediate medical care if chest pain persists after using 3 packets.
