Discharge Instructions: Taking Long-Acting Nitroglycerin

Your doctor prescribed a nitroglycerin for you. Nitroglycerin relieves angina (chest pain caused by a lack of blood to the heart) by getting more oxygen-rich blood to your heart. Long-acting nitroglycerin helps prevent angina. Follow the steps below for taking long-acting nitroglycerin.

Guidelines for Use

  • Follow the fact sheet that came with your medication. It tells you when and how to take your medication. Ask for a sheet if you didn’t get one.

  • Don’t suddenly stop using nitroglycerin. This could cause an angina attack. If you wish to stop taking your medication, talk with your doctor first.

  • Limit alcohol intake. Too much alcohol can cause dizziness or fainting.

  • Do not take Viagra, Levitra, or Cialis (drugs used to treat impotence) at all if you use long-acting nitroglycerin. The combination of nitroglycerin with Viagra, Levitra, or Cialis can cause a severe drop in blood pressure. This can lead to dizziness, fainting, heart attack (also known as acute myocardial infarction, or AMI), or stroke.

  • To use a nitroglycerin patch:

    • Remove the old patch.

    • Apply a new patch to a clean, dry place on your chest or upper arm.

    • Pick a new place each time you put on a new patch.

    • Don’t apply a patch where your skin is hairy, cut, irritated, scarred, or tattooed.

  • To use a nitroglycerin tablet or capsule:

    • Take the tablet or capsule 60 minutes before or 2 hours after eating.

    • Swallow the medication with a glass of water.

    • Don’t break, chew, or crush the tablet or capsule.

  • To use a nitroglycerin ointment:

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

    • 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 ointment.
