USES: Nitroglycerin relaxes blood vessels allowing more blood to flow through and improves blood flow to the heart. Topical nitroglycerin skin patches are used to prevent angina (chest pain). This medication is NOT for treating an attack of chest pain that has already started.
HOW TO USE: Transdermal skin patches are to be applied to a clean, hairless area on the upper arm or chest not subject to excessive movement. The patch should remain in place while bathing or showering. Remove the previous patch before applying a new one. Apply the new patch to a different area to minimize skin irritation by using a new area of skin. The patch is usually worn for 12 to 14 hours a day and then a new patch put on 10 to 12 hours later or as directed. This drug-free period improves the drug's effectiveness. Do not stop using this drug suddenly without consulting your doctor. Some conditions may worsen when the medication is suddenly stopped. Your dose may need to be gradually decreased.

If any of these effects persist or become bothersome, inform your doctor. To prevent dizziness and lightheadedness when rising from a seated or lying position, get up slowly.

Treat headaches with an aspirin or non-aspirin pain reliever as recommended by your doctor. If the headaches continue or become severe, notify your doctor.
