How does this medication work? What will it do for me?
Nitroglycerin belongs to the class of medications called antianginals. Nitroglycerin ointment is used to prevent angina attacks (chest pain). Nitroglycerin reduces the number of angina attacks by relaxing blood vessels and increasing the oxygen and blood supply to the heart. Nitroglycerin ointment is not intended for immediate relief of angina.

How should I use this medication?
Nitroglycerin ointment may be applied every 3 to 8 hours if necessary, but one application at bedtime is often sufficient for the entire night. The usual dose is 2.5 cm to 5 cm as squeezed from the tube onto the applicator.
You may use the ointment on any convenient skin area - many people prefer to apply it to the chest. Place the applicator with the ointment side down onto the desired area. Spread the ointment over at least a 5 cm by 7.5 cm area in a thin, uniform layer. Cover the ointment with the supplied paper, plastic kitchen wrap, or other suitable material. This can be held in place with adhesive or transparent tape.

It is important to use this medication exactly as prescribed by your doctor. If you miss a dose, apply it as soon as possible and continue with your regular schedule.

If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
