The nitroglycerin patch is available by prescription only and is used to prevent chest pain (angina). The medicine comes in the form of a patch and is applied to the skin once a day. It is only worn for 12 to 14 hours each day, as the body needs a break from the drug. Possible side effects may include headaches, lightheadedness, and fainting.
