Long-Acting Nitroglycerin  

Nitroglycerin relieves angina (chest pain) by getting more blood and oxygen to your heart. Long-acting nitroglycerin helps prevent angina from starting.

To Prevent Angina

If you use a patch:

• Remove the old patch. Then apply a new one to a clean, dry place on the chest or upper arm.

• Pick a new place each time you change the patch.

• Do not apply where skin is hairy, cut, irritated, scarred, or tattooed.

If you use a tablet or capsule:

• Take the tablet or capsule 1 hour before or 2 hours after eating.

• Swallow it with a glass of water. Do not break, chew, or crush the tablet or capsule.

If you use an ointment:

• Measure the prescribed amount of ointment onto the paper that comes with it.

• Spread a thin, even layer on a clean patch of skin. Do not rub it in. Tape the paper in place with skin tape for as long as instructed, then remove it.

• Use a new spot each time you apply the paste.

 

 Precautions

• Do not suddenly stop using nitroglycerin to prevent angina. This could cause an attack. Check with your healthcare provider first.

• Limit the amount of alcohol you drink. Too much alcohol can cause dizziness or fainting.

• Tell your healthcare provider about any medications, supplements, or herbs you use. Nitroglycerin can interact with other medications and cause serious problems. NOTE: Do not take Viagra, Levitra, or Cialis at any time if you are on nitroglycerin.

• Check the expiration date. Nitroglycerin can lose its effectiveness over time.
