What Decapeptyl is used for
Decapeptyl contains triptorelin, which is a synthetic version of the natural gonadotropin releasing hormone (GnRH). GnRH regulates the release of two gonadotropins that are involved in the development of follicles and release of eggs from the ovaries: follicle-stimulating hormone (FSH) and luteinising hormone (LH).
Assisted Reproductive Technology (ART) include gonadotropins that replace the activities of naturally produced FSH and LH. Occasionally, in response to ART treatment, the release of eggs may occur too early due to an early surge in LH levels and this may lead to that ART cycle being cancelled, without retrieval of any eggs. Decapeptyl blocks the action of GnRH and is therefore intended to prevent an LH surge, thereby lessening the chances of premature ovulation and a cancelled ART cycle.
Ask your doctor if you have any questions about why it has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is not addictive.
This medicine is available only with a doctor's prescription.
This medicine is not expected to affect your ability to drive a car or operate machinery.

How to use Decapeptyl
This medicine contains a solution of triptorelin provided in a pre-filled disposable syringe for single use. It is given as an injection under the skin (subcutaneous) of the lower abdomen.
If your doctor or nurse decides you can give the injections to yourself, they will train you appropriately on the injection technique.
Do not self-inject Decapeptyl until you are sure of how to do it.
The first injection of Decapeptyl should be under medical supervision.
Follow all instructions given to you by your doctor carefully.
An instruction leaflet is supplied with your medicine and the following information is included:
Injecting your medicine
- Remove the protective foil and take the syringe out of the blister packaging.
- Keep the syringe upright with the grey protective cap facing up.
- Remove the grey protective cap.
- Gently push the plunger until the first drops of liquid appear at the needle tip.
- The medicine is to be injected under the skin of the lower abdomen. Clean the injection site with an antiseptic swab immediately prior to injection.
- Lift up a fold of skin between the thumb and forefinger. With your free hand hold the syringe at a right angle to the skin like a dart and quickly insert the needle all the way into the skin fold. Press down slowly on the plunger to inject the contents of the syringe.
- Remove the syringe and needle from the skin and discard this immediately into a sharps disposal unit.
- For each dose, choose a different injection site along the lower abdomen.
Other important information
- Each pre-filled syringe is for single use only.
- Tell your doctor immediately or go to Accident and Emergency at your nearest hospital if you experience sign/symptoms of an allergic reaction (e.g. difficulty in breathing or swelling of the lips).
- The first injection of this medicine should be supervised by your doctor or nurse.
- The syringe should be disposed into a sharps disposal unit.
How much to use
Always use this medicine exactly as your doctor has told you. You should check with your doctor if you are not sure.
The usual dosage of Decapeptyl is one injection under the skin of your lower abdomen once-daily.
Treatment can be started on day 2 or 3, or on day 21 to 23, of the menstrual cycle.
After 2 to 4 weeks of Decapeptyl treatment, other hormones (gonadotropins) will be given in order to stimulate follicle growth.
In general, Decapeptyl treatment will continue until follicles have reached a suitable size, usually 4 to 7 weeks.
If enough follicles are present, Decapeptyl treatment will be stopped and you will be given a medicine to induce ovulation.
Your doctor will closely monitor your progress for at least another 2 weeks.
How long to use it
Usually one dose of Decapeptyl is used each day. The length of Decapeptyl treatment is usually from 4-7 weeks. However, your doctor will be able to answer this question more precisely.
If you forget to use it
It is important that you do not miss a dose of Decapeptyl.
If you do miss a dose, contact your doctor or nurse. Do not take a double dose to make up for the dose that you missed.
If you use too much (overdose)
As your treatment will be closely monitored it is unlikely you will be prescribed too large a dose of Decapeptyl. However, Decapeptyl can be associated with some symptoms (see Side effects). If you use more than the prescribed dose contact a doctor immediately.
While you are using Decapeptyl
In case you suffer from a reaction after injecting Decapeptyl you should contact your doctor immediately. Symptoms of a reaction can include:
- pain in the abdomen
- swelling in the abdomen
- weight gain
- difficulty breathing
- decreased urination.
Tell your doctor straight away, even if the symptoms develop some days after the last injection has been given. These can be signs of high levels of activity in the ovaries which might become severe (see also section Side effects).
If these symptoms become severe, the infertility treatment should be stopped and you should receive treatment in hospital.
Undergoing infertility treatment with hormones, like this medicine, has been associated with increased risk of:
- ectopic pregnancy (pregnancy outside of the womb) if you have a history of fallopian tube disease
- multiple pregnancy (twins, triplets, etc.)
- congenital malformations (physical defects present in baby at birth).
Things you must do
Tell your doctor immediately if you become pregnant while using Decapeptyl.
Tell your doctor if you have abnormal vaginal bleeding while using Decapeptyl.
Be sure to keep all your doctor's appointments so your progress can be checked.
Your doctor will normally arrange for you to have ultrasound scans and sometimes blood tests to monitor your response to treatment.
Tell any other doctors, dentists, and pharmacists who are treating you that you are using Decapeptyl.
If you are about to be started on any new medicine, tell your doctor, dentist or pharmacist that you are using Decapeptyl.
If you are going to have surgery, tell the surgeon or anaesthetist that you are using Decapeptyl.
Things to be careful of
Decapeptyl should not normally interfere with your ability to drive or operate machinery.
Take special care with Decapeptyl
Decapeptyl can lead to mood changes (including depression).
Long-term use (over many months or years) of Decapeptyl for other conditions can lead to thinning of bones, which may increase risk of bone fracture.
If you are at additional risk of thinning of the bones (osteoporosis) you should tell you doctor before taking Decapeptyl.
Tell your doctor or nurse or pharmacist as soon as possible if you do not feel well after you use Decapeptyl.
