Why is this medication prescribed?

Nitroglycerin topical is prescribed for the treatment of certain conditions, most commonly anal fissures and chronic anal fissures. An anal fissure is a small tear or ulcer in the lining of the anal canal, which can cause pain, discomfort, and bleeding during bowel movements. Nitroglycerin topical works by relaxing the smooth muscles around the anal sphincter, increasing blood flow, and reducing pressure in the area. This helps to relieve pain and promote the healing of the fissure.

Nitroglycerin is a vasodilator, meaning it widens blood vessels and improves blood flow. When applied topically, it is absorbed through the skin and produces its effects locally. By relaxing the smooth muscles and increasing blood supply to the affected area, nitroglycerin helps to reduce the spasm and promote healing of the anal fissure.

How should this medicine be used?

Nitroglycerin topical should be used exactly as prescribed by your healthcare provider. It typically comes in the form of a cream or ointment and is applied directly to the affected area. Here are some general guidelines for using nitroglycerin topical:

• Clean the area: Before applying the medication, make sure the affected area is clean and dry. You can use mild soap and water to gently cleanse the area and pat it dry with a clean towel.
• Apply a thin layer: Take a small amount of the nitroglycerin cream or ointment and apply a thin layer directly to the affected area. It is usually recommended to use a fingertip or a gloved finger to apply the medication.
• Rub it in gently: Gently rub the cream or ointment into the skin until it is absorbed. Avoid applying excessive pressure or massaging the area vigorously.
• Wash your hands: After applying the medication, wash your hands thoroughly to remove any residue. This will prevent unintentional transfer of the medication to other areas of your body or accidental ingestion.
• Follow the prescribed schedule: Nitroglycerin topical is typically applied two to three times a day, as directed by your healthcare provider. It’s important to follow the prescribed schedule and not exceed the recommended dosage.
• Avoid contact with eyes and mucous membranes: Nitroglycerin can cause irritation if it comes into contact with your eyes or mucous membranes (such as inside your nose or mouth). Be cautious while applying the medication to avoid contact with these areas. If accidental contact occurs, rinse the affected area with water immediately.
• Store properly: Keep the medication tightly sealed in its original container and store it at room temperature, away from heat and direct sunlight. Follow any specific storage instructions provided by the pharmacist or manufacturer.

Remember to consult your doctor or pharmacist for specific instructions tailored to your condition and the prescribed nitroglycerin topical product. They will provide you with detailed guidance on how to use the medication effectively and safely.
