Generic Name: nitroglycerin (NYE-troe-GLIS-er-in)
Brand Name: NitroMist
Nitroglycerin aerosol is used for:
Preventing or relieving a sudden attack of angina (chest pain) caused by heart disease. It may also be used for other conditions as determined by your doctor.
Nitroglycerin aerosol is a nitrate. It works by dilating (widening) blood vessels. Chest pain occurs when the heart needs more oxygen than it can get. Dilating blood vessels allows blood to flow more easily. This reduces the heart's workload and the amount of oxygen needed by the heart.
Do NOT use nitroglycerin aerosol if:
- you are allergic to any ingredient in nitroglycerin aerosol, to other nitrates (eg, isosorbide mononitrate), or to nitrites
- you have severe anemia or increased pressure in the head
- you are also taking avanafil, riociguat, sildenafil, tadalafil, or vardenafil
Contact your doctor or health care provider right away if any of these apply to you.
Before using nitroglycerin aerosol:
Some medical conditions may interact with nitroglycerin aerosol. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have a history of other heart problems (eg, heart failure, enlarged heart, heart attack), overactive thyroid, stroke or other bleeding in the brain, or recent head injury
- if you have anemia, low blood pressure, dehydration, or low blood volume
- if you drink alcoholic beverages
Some MEDICINES MAY INTERACT with nitroglycerin aerosol. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Avanafil, beta-blockers (eg, propranolol), calcium channel blockers (eg, diltiazem), diuretics (eg, furosemide, hydrochlorothiazide), medicines for high blood pressure, phenothiazines (eg, thioridazine), riociguat, sildenafil, tadalafil, or vardenafil because the risk of low blood pressure and dizziness on standing may be increased
- Salicylates (eg, aspirin) because they may increase the risk of nitroglycerin aerosol's side effects
- Long-acting nitrates (eg, nitroglycerin patch) because they may decrease nitroglycerin aerosol's effectiveness
- Ergot derivatives (eg, ergotamine, dihydroergotamine) because the risk of their side effects may be increased by nitroglycerin aerosol
- Alteplase because its effectiveness may be decreased by nitroglycerin aerosol
This may not be a complete list of all interactions that may occur. Ask your health care provider if nitroglycerin aerosol may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
