Glyceryl trinitrate patches are used to prevent angina and sometimes other conditions. They relax the blood vessels, allowing more blood to flow to the heart.
Use glyceryl trinitrate patches regularly as directed. Apply the patch to a clean, hairless area of skin at the same time each day. Remove the patch about 16 hours later and wait at least 8 hours before applying a new patch. Apply the new patch to a different area of skin, to prevent skin irritation. Do not cut the patch.
Apply the missed patch as soon as possible and remove it at the normal time.
Some medicines available without a prescription may react with glyceryl trinitrate including:
Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
