How should I use nitroglycerin transdermal (Transderm Nitro)?

Use this medication exactly as it was prescribed for you. Do not use the medication in larger amounts, or use it for longer than recommended by your doctor. Follow the directions on your prescription label.

Do not use nitroglycerin transdermal to treat an angina attack that has already begun. It will not work fast enough. Your doctor may prescribe an oral form of nitroglycerin (tablet, capsule, spray) to treat an angina attack. Talk with your doctor if any of your medications do not seem to work as well in treating or preventing angina attacks.

The nitroglycerin transdermal 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.

Apply the skin patch to a clean, dry, hairless area of the body, below your neck and above your knees or elbows. To remove any hair from these skin areas, clip the hair short but do not shave it.

Press the patch onto the skin and press it down firmly with your fingers. Make sure it is well sealed around the edges.

Wash your hands after applying a nitroglycerin transdermal skin patch.

If the patch falls off, try sticking it back on. If you replace the patch with a new one, leave it on only for the rest of your wearing time. Do not change your patch removal schedule.

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.

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

Store this medication at room temperature, away from moisture and heat. Keep each skin patch in its sealed pouch until you are ready to use it.
