Nitrogesic Ointment 30 g (Generic)

What Nitrogesic ointment is used for

Nitrogesic ointment 30 g is prescribed for managing anal fissure symptoms. It is not a general pain cream. It is meant to be applied around the anal opening only, as directed. The medicine works locally, so you need only a small amount for each application.

Doctors may choose this ointment when an anal fissure does not heal with basic care like warm baths, more fiber in the diet, or stool softeners. You may use the ointment for a few weeks. Keep using it for the full length of time your doctor recommends, even if the pain starts to improve.

How nitroglycerin works in this ointment

Nitroglycerin is a nitrate that relaxes smooth muscles. In the anal area, it helps the internal anal sphincter relax. This reduces pressure inside the anal canal.

Lower pressure allows more blood to reach the fissure. More blood flow means the tissue gets more oxygen and nutrients, which supports healing. The relaxant effect also reduces painful spasms that often happen after bowel movements.

How to use Nitrogesic ointment

• Use only the amount your doctor tells you to use.
• Do not apply the ointment inside the rectum unless your doctor says so.
• Do not cover the area with tight dressings unless advised.
• Avoid getting the ointment in the eyes or mouth.
• Do not use it more often than prescribed, as this can increase side effects.

Side effects of Nitrogesic ointment

Nitroglycerin ointment can cause side effects, and they vary from person to person. The most common one is headache. Nitroglycerin widens blood vessels, which can lead to a throbbing headache, especially right after application. This often gets better with continued use, but if headaches are severe, tell your doctor.

Other possible side effects include:

• Dizziness or lightheadedness
• Burning, itching, or mild irritation at the application site
• Redness or mild rash
• Feeling faint

Who should be careful with this medicine?

• Low blood pressure
• Severe anemia
• Migraines or frequent headaches
• Heart problems
• Increased pressure inside the head
• Kidney or liver disease

Strengths and packaging

This product comes as a 30 g tube of 0.2% nitroglycerin ointment. It is a generic version of the branded ointment. Other nitroglycerin ointment products for anal fissure may come as 0.4% strength under different brand names.

Compounding pharmacies may also prepare nitroglycerin ointment in different strengths, but you should use these only with a clear prescription from a doctor. The 0.2% and 0.4% strengths are not automatically interchangeable without medical advice.
