Nitro Patch (Nitroglycerin)

Nitroglycerin patches are used to prevent chest pain (angina) by relaxing blood vessels and improving blood flow to the heart. Apply to clean, dry, hairless skin on the upper arm or chest, pressing firmly for 10-20 seconds. Wear for 12-14 hours daily, followed by a 10-12 hour patch-free period to prevent tolerance. Rotate application sites to avoid skin irritation. Follow your doctor's instructions.
