How your NITRO-DUR Nitroglycerin Transdermal System works

NITRO-DUR is applied directly to the skin. The nitroglycerin passes from the adhesive surface through the skin—allowing medication to be absorbed directly into the bloodstream. Nitroglycerin causes the blood vessels to relax and increases the supply of blood and oxygen to the heart.

The amount of NITRO-DUR you need will depend upon your body's needs. Observe the dosing instructions given to you by your doctor and report to him/her if your condition changes.

Instructions for Use: Placement Area

Select a reasonably hair free application site. Avoid extremities below the knee or elbow, skin folds, scar tissue, burned or irritated areas.


Wash hands before applying. Hold the unit with brown lines facing you, in an up and down position. Bend the sides of the unit away from you, then toward you until you hear the snap. Twist the patch gently to lift the plastic backing. Peel off one side of the plastic backing. Using the other half of the backing as a handle, apply the sticky side of the patch to the skin. Press the sticky side on the skin, and smooth down. Fold back the remaining side of the patch. Grasp the edge of the plastic applicator by the stripe, and pull it across the skin. Wash hands to remove any drug.


Press down on the center of the system to raise its outer edge away from the skin. Grasp the edge gently, and slowly peel the patch away from the skin. Wash skin area with soap and water. Towel dry. Wash hands. You should use a different application site every day.

Skin Care

  1. After you remove NITRO-DUR, your skin may feel warm and appear red. This is normal. The redness will disappear in a short time. If the area feels dry, you may apply a soothing lotion.

  2. Any redness or rash that does not disappear within a few hours should be called to your physician's attention.

Things to be Aware of

There are certain things you and your doctor should be aware of before you use NITRO-DUR.

Before using NITRO-DUR be sure to tell your doctor if you have ever had any unusual or allergic reactions to nitrates or nitrites, or have had a recent heart attack, or other serious heart disease, stroke, or head injury; severe anemia or narrowing of the heart valves. Tell your doctor if you are breast-feeding or pregnant or intend to become pregnant while using this medicine. This will help the doctor decide whether you should use NITRO-DUR and what extra care should be taken during its use. There are some medicines which may affect how NITRO-DUR works. Tell your doctor what other medicines or remedies, if any, you are using.

Check with your doctor as soon as possible if any of the following occur: angina (chest pain), particularly while patch is off; dizziness or fainting; feeling of pressure in the head; shortness of breath; unusual tiredness or weakness; weak or unusually fast heartbeat.

Possible Unwanted Effects

Like all medicines, along with its helpful effects, NITRO-DUR may cause unwanted effects. You should know about them so that if they do occur, you can report them to your doctor right away.

When you start using NITRO-DUR, you may get a headache. This is a common effect. If you need to, you may take a mild pain reliever for this. If it continues or becomes severe, check with your doctor. Flushing of the face may also occur. NITRO-DUR may also lower the blood pressure and cause dizziness, lightheadedness, or a fainting feeling, especially when you get up quickly from lying or sitting. Getting up slowly may help. If you feel dizzy, sit or lie down. You may be more likely to experience headaches, dizziness, or lightheadedness if you drink alcohol, stand for a long time, or if the weather is hot. While using NITRO-DUR, be careful about the amount of alcohol you drink. Also use extra care when exercising, standing for a long time, driving, or during hot weather.

If you are using NITRO-DUR (nitroglycerin), you must not take Viagra (sildenafil citrate) or Cialis (tadalafil). Such a combination can produce severe lowering of blood pressure, loss of consciousness, heart attack or death.
