How does this medication work? What will it do for me?Nitroglycerin belongs to the class of medications called anti-anginals. Nitroglycerin is used to relieve acute attacks of angina (chest pain). Nitroglycerin relieves acute angina attacks by relaxing blood vessels and increasing the oxygen and blood supply to the heart.

How should I use this medication?
To use this medication, spray it once or twice (as directed by doctor) onto or under the tongue at the first sign of an angina attack. Do not inhale. The dose may be repeated twice with at least a five minute interval between each dose, or as directed by your doctor. If relief is still not obtained after three doses of nitroglycerin (i.e., 15 minutes), seek medical help immediately.
While using nitroglycerin spray, remain at rest in a sitting position and keep the container vertical with the nozzle head up. Place the opening in the nozzle head as close to the mouth as possible. Avoid getting the spray in your eyes.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Dizziness: This treatment may cause temporary dizziness. Do not drive, operate machinery, or perform other hazardous tasks until you have determined how this medication affects you.
Low blood pressure: Headaches or symptoms of low blood pressure, such as weakness or dizziness, particularly when getting up suddenly from a lying or sitting position, may result from taking too much nitroglycerin. If these symptoms occur, your doctor may reduce the dose or stop the use of nitroglycerin. People who might be negatively affected by low blood pressure should use nitroglycerin spray with caution. People who take diuretics or have pre-existing low blood pressure may be at more risk of experiencing low blood pressure. Discuss any concerns you might have with your doctor.
Medical conditions: The benefits and safety of nitroglycerin spray for people who have an acute heart attack or congestive heart failure have not been established.
Tolerance: Nitroglycerin users may develop tolerance to the medication, resulting in it not working as well. Tolerance to other nitrates or nitrites can also happen, especially if long-acting nitrates are being used at the same time. As tolerance to nitroglycerin develops, the effect of fast-acting sublingual (under the tongue) nitroglycerin is somewhat reduced.
Pregnancy: This medication has not been studied for use by pregnant women. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known whether this medication passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of this medication for children have not been established.
