Nitrol Dosage

Nitrol (Nitroglycerin) ointment may be applied every 3 to 8 hours if necessary, but one application at bedtime is often sufficient for the entire night. The usual dose is 2.5 cm to 5 cm as squeezed from the tube onto the applicator.

You may use the ointment on any convenient skin area – many people prefer to apply it to the chest. Place the applicator with the ointment side down onto the desired area. Spread the ointment over at least a 5 cm by 7.5 cm area in a thin, uniform layer. Do not rub the Nitrol (Nitroglycerin) into the skin. Cover the ointment with the supplied paper, plastic kitchen wrap, or other suitable material. This can be held in place with adhesive or transparent tape. Before applying your next dose of Nitrol (Nitroglycerin), wipe off any remaining ointment from the area where the previous dose was applied.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are applying the medication without consulting your doctor.

It is important to use Nitrol (Nitroglycerin) exactly as prescribed by your doctor. If you miss a dose, apply it as soon as possible and continue with your regular schedule.

If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
