Read the Patient Information Leaflet if available from your pharmacist before you start using nitroglycerin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Cover your finger with plastic wrap, a disposable medical glove, or a finger cot. Using the measuring guide that comes with your product, squeeze out the prescribed amount of ointment onto your finger. Gently insert your finger inside the anus, up to the first finger joint. Spread the ointment around the inside of the anus. If you cannot do this because it is too painful, you may apply the ointment to the outside of the anus.

Throw away the finger covering and wash your hands after each dose. Apply this medication as directed by your doctor, usually every 12 hours for up to 3 weeks. Do not apply this medication in the eyes, mouth, or vagina.

Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day.

Tell your doctor if your pain does not get better.
