How should I use Nitro TD Patch-A 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 Nitro TD Patch-A patch at a time. Using extra skin patches will not make the medication more effective. Never cut a skin patch.
The Nitro TD Patch-A 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.
Nitro TD Patch-A 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 Nitro TD Patch-A.
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 Nitro TD Patch-A skin patches out of the reach of children or pets.
What happens if I miss a dose?
Apply a patch as soon as you remember, and keep it on for the rest of your wearing time without changing your patch removal schedule. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra patches to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. The amount of Nitro TD Patch-A in a used skin patch could be dangerous to a child or pet who accidentally chews on the patch.
Overdose symptoms may include a severe throbbing headache, confusion, fever, fast or pounding heartbeats, dizziness, vision problems, vomiting, bloody diarrhea, trouble breathing, cold or clammy skin, fainting, and seizures.
