The name of my long-acting nitroglycerin medicine is ____________________________________.

Guidelines for use

• Follow the fact sheet that came with your medicine. It tells you when and how to take your medicine. 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 medicine, talk with your provider first.

• Limit how much alcohol you drink. Too much alcohol can cause dizziness or fainting.

• Don't take certain medicines used to treat erectile dysfunction, such as sildenafil or tadalafil if you use long-acting nitroglycerin. The combination of nitroglycerin with these medicines can cause a severe drop in blood pressure. This can lead to dizziness or fainting. It can raise the risk for heart attack and 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 pill with a glass of water.

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

• To use a nitroglycerin ointment:
