What Suprefact Depot is and what it is used for
Suprefact Depot contains a medicine called buserelin. Buserelin is similar to a naturally occurring hormone released by the brain. It belongs to a group of medicines called “luteinizing hormone-releasing hormone analogs” (LHRH analogs).
Suprefact Depot is used in the treatment of advanced prostate cancer or premature puberty.
In prostate cancer, Suprefact Depot works by inhibiting the production of testosterone, a male sex hormone. In addition to its normal hormonal effects, testosterone can have a stimulating effect on the growth of certain tumors. After 3 – 4 weeks of treatment with Suprefact Depot, the concentration of testosterone has dropped to a very low level.
In premature puberty, Suprefact Depot works by inhibiting sex hormones. In girls, breast development stops or regresses. After initial bleeding, any menstrual bleeding stops in parallel with the decline of the sex hormones in the body. In boys, the growth of the testicles and other signs of puberty stop.
What you need to know before using Suprefact Depot
Do not use Suprefact Depot
- If you are allergic to buserelin or any of the other LHRH analogs (e.g. leuprolide, goserelin, triptorelin) or any other ingredient in this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor or pharmacist before starting treatment with Suprefact Depot:
- If you have had your testicles removed.
- If your cancer has spread ( metastasized ).
- If you have an increased risk of cardiovascular disease (e.g. heart attack).
- If you have any cardiovascular disease including heart rhythm disorders ( arrhythmia ) or are being treated with drugs for this. The risk of suffering from heart rhythm disorders may be increased when using Suprefact Depot.
- If you have diabetes. Check your blood sugar levels regularly. This is because Suprefact Depot can affect your metabolism and thus your blood sugar levels.
- If you have high blood pressure. Your doctor or nurse should regularly check your blood pressure as blood pressure can be affected by Suprefact Depot.
- If you have ever had depression. You should be vigilant about your mental health because there is a risk that your depression may return or worsen.
Suprefact Depot can cause a decrease in bone density, osteoporosis (weakening of the bones), and an increased risk of bone fractures, especially if you have risk factors for osteoporosis such as alcohol abuse, are smokers, have a family history of osteoporosis, or if you have been treated for a long time with anti- epilepsy or with cortisone. Your doctor should measure your bone density regularly to be able to prescribe preventive measures against osteoporosis if necessary.
At the beginning of prostate cancer treatment, tumor activation can occur (see section 4. Possible side effects ), therefore the addition of an antiandrogenic drug is recommended approximately 5 days before treatment begins and during the first 3-4 weeks of treatment with Suprefact Depot. After this period, testosterone levels have usually decreased to the desired level as a result of the buserelin treatment.
At the beginning of treatment for premature puberty, vaginal bleeding is common.
Other medicines and Suprefact Depot
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Suprefact Depot can affect or be affected by certain other medicines.
Talk to your doctor especially if you are using:
- drugs against diabetes. This is because Suprefact Depot can reduce the effect of these medicines.
- medicines to treat heart rhythm disorders (eg quinidine, procainamide, amiodarone, and sotalol).
- other medicines that may increase the risk of heart rhythm disturbances when used together with Suprefact Depot, eg methadone (used as a pain reliever and in the treatment of drug addiction), moxifloxacin (an antibiotic ), antipsychotics (used in severe mental illnesses).

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects.
Description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with a doctor or pharmacist if you are unsure.

Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Contact a doctor immediately if you develop symptoms such as a rash, difficulty swallowing or breathing, swelling of the lips, face, throat, or tongue. This could be a serious allergic reaction. Inform that you have Suprefact Depot implants, as it may be necessary to remove the implant et.
At the beginning of prostate cancer treatment, the amount of testosterone your body produces may increase and you may experience a temporary worsening of symptoms. Contact a doctor if you experience symptoms such as bone pain, worsening bone pain (in patients with metastases ), muscle weakness in the legs, problems with urination, fluid retention, or blood clots in the lungs. These reactions can largely be avoided by treatment with a so-called antiandrogenic drug, see section 2.
