## How should I use nitroglycerin transdermal?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Wash your hands after applying or removing a skin patch.

Do not wear more than one nitroglycerin transdermal patch at a time. Using extra skin patches will not make the medication more effective. Never cut a skin patch.

The nitroglycerin skin patch is usually worn for 12 to 14 hours and then removed. A new patch is put on after a "patch-free" period of 10 to 12 hours. Your doctor may want you to wear the patch for longer or shorter periods of time. Follow your doctor's instructions carefully.

You may have very low blood pressure while using nitroglycerin. Call your doctor if you are sick with vomiting or diarrhea, or if you are sweating more than usual.

Nitroglycerin transdermal will not work fast enough to treat an angina attack. Your doctor may prescribe a fast-acting medicine to treat an angina attack. Tell your doctor if it seems like any of your medicines don't work as well in treating or preventing angina attacks.

If you need surgery or medical tests, tell the surgeon or doctor ahead of time that you are using nitroglycerin transdermal.

Do not stop using this medicine without your doctor's advice, even if you feel fine. You may have increased angina attacks if you stop using the medication suddenly.

Store at room temperature, away from moisture and heat. Do not refrigerate. Keep each skin patch in its sealed pouch until you are ready to use it.

After removing a skin patch fold it in half, sticky side in, and throw it away in a place where children or pets cannot get to it. Keep both used and unused nitroglycerin skin patches out of the reach of children or pets.
