If you use nitroglycerin sublingual spray to treat an angina attack: At the first sign of an attack, apply the spray directly on or under your tongue. Close your mouth after each spray. Do not inhale the spray. Do not shake the spray before or during use. You may use additional sprays every 5 minutes, but not more than 3 sprays in 15 minutes.
You may use nitroglycerin spray within 5 to 10 minutes before an activity you think might cause chest pain. Follow your doctor's instructions.

Seek emergency medical attention if your chest pain gets worse or lasts more than 5 minutes, especially if you have trouble breathing or feel weak, dizzy, or nauseated, or lightheaded.

Keep this medicine on hand at all times in case of an angina attack. Get your prescription refilled before you run out of medicine completely.
