About glyceryl trinitrate rectal ointment

An anal fissure is a small tear of the skin around your back passage (anus). Glyceryl trinitrate (GTN) rectal ointment (Rectogesic®) works by relaxing the muscle just inside your back passage. Relaxing this muscle increases the flow of blood to the area, which eases pain. It can be helpful where other treatments have not been effective.

A different brand of glyceryl trinitrate ointment (Percutol®) is used to relieve angina pain. For information on this product please see our medicine leaflet ثلاثي نترات الجلسرين للذبحة الصدرية.

Before using glyceryl trinitrate rectal ointment

To make sure that this is the right treatment for you, before you start using GTN rectal ointment it is important that your doctor knows:

• إذا كنت حاملاً أو مرضعة.

• إذا كان لديك أي مشاكل في طريقة عمل الكبد لديك، أو أي مشاكل في طريقة عمل الكلى لديك.

• If you have migraines or severe headaches.

• If you have low blood pressure, or a heart condition.

• If you have been told by a doctor you have low levels of iron in your blood (anaemia), or low levels of oxygen in your blood (hypoxaemia).

• إذا كان لديك غدة درقية غير نشطة.

• إذا كنت تعاني من حالة في العين تسمى الجلوكوما.

• If you have recently had a head injury or a heart attack.

• إذا كنت قد تعرضت في أي وقت مضى لرد فعل تحسسي تجاه دواء.

How to use glyceryl trinitrate rectal ointment

• Before you use the ointment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about using the ointment, and it will also provide you with a full list of side-effects which you could experience.

• Cover your finger with a finger cot (available from pharmacies), or a piece of cling film, or use a disposable glove. Then measure out 2.5 cm of the ointment from the tube on to your finger (there is a measuring line on the packaging to help you). Then, using your finger, gently insert the ointment just inside your back passage. To make sure that the ointment gets to the correct place, insert your finger to the first finger joint. Apply the ointment this way every 12 hours until the pain goes away. You can continue to use the ointment for up to eight weeks, if needed.

تحقيق أقصى استفادة من علاجك

• Remember to follow any lifestyle or dietary advice you have been given by your doctor. Try to avoid becoming constipated, by eating a high-fibre diet and drinking several glasses of water each day.

• It is best not to drink alcohol while you are using GTN rectal ointment. Alcohol will increase the chance that you experience side-effects such as feeling dizzy and light-headed.

• If you experience any bleeding from your back passage, or if your symptoms do not improve, you should discuss this with your doctor.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take while you are using GTN rectal ointment.
