Nitroglycerin ointment is used to prevent chest pain (angina) in people with a certain heart condition (coronary artery disease). This medication belongs to a class of drugs known as nitrates. Angina occurs when the heart muscle is not getting enough blood. This drug works by relaxing and widening blood vessels so blood can flow more easily to the heart.
This medication will not relieve chest pain once it occurs. It is also not intended to be used just before physical activities (such as exercise, sexual activity) to prevent chest pain. Other medications may be needed in these situations. Consult your doctor for more details.
How To Use
Read the Patient Information Leaflet available from your pharmacist. Consult your doctor or pharmacist if you have any questions.
Avoid touching the ointment with your fingers. Carefully squeeze out your dose onto a paper dose-measuring applicator. These applicators are supplied with the medication. Place the paper applicator with the ointment side down onto a dry, hairless area of skin, usually on the chest. Do not rub the ointment into the skin. Using the paper, lightly spread the ointment to cover an area of a size directed by your doctor. Tape the paper applicator into place and cover with plastic wrap to avoid staining your clothing. Wash your hands after applying and removing the medication.
Apply this medication usually 3 to 4 times daily or as directed by your doctor. Remember to use a different area for each application. It is important to apply this medication at the same times each day. Do not change the dosing times unless directed by your doctor. The dosage is based on your medical condition and response to treatment. Remove the medication daily as directed by your doctor.
Use this medication regularly to get the most benefit from it. Do not stop using this medication without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.
Although unlikely, when this medication is used for a long time, it may not work as well and may require different dosing. Tell your doctor if this medication stops working well (for example, you have worsening chest pain or it occurs more often).
