What Lucrin is used for

Lucrin is used to treat prostate cancer.
It belongs to a group of medicines called gonadotropin releasing hormone agonists.
It works by blocking the secretion of hormones from testes.In some types of cancer, these hormones help the cancer cells to grow.By blocking these hormones, Lucrin may slow or stop the growth of prostate cancer.
Ask your doctor or pharmacist if you have any questions about why it has been prescribed for you.
Your doctor may have prescribed it for another purpose.
Lucrin is available only with a doctor’s prescription.
Lucrin should not be given to children.

Lucrin may cause fertility problems in men. Use of this medicine for a short time has shown a full return to fertility after stopping the medicine. Fertility suppression may or may not be permanent when the medicine is given for a long time.
Certain strengths of Lucrin have not been tested in children so the safety and effectiveness in children is not fully known.
If you have not told your doctor about any of the above, tell them before you are given Lucrin.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food store.
Lucrin has not been found to interact with other commonly used medicines. If you have any questions or concerns, discuss them with your doctor or pharmacist.

methadone, a medicine used to reduce withdrawal symptoms associated with drug addiction
certain antibiotics such as moxifloxacin, a medicine used to treat infections caused by certain bacteria
antipsychotic medicines
Taking these medicines together with Lucrin may increase the risk of abnormal heart rhythms.

How long to take it

Continue having your injections for as long as your doctor tells you.

If you missed your injection or are not sure what to do, check with your doctor or pharmacist.


As Lucrin is given to you under the supervision of your doctor, it is unlikely that you will receive too much. However, if you experience any side effects after being given this medicine, telephone your doctor, or the Poisons Information Centre (telephone Australia 13 11 26), or go to Accident and Emergency at your nearest hospital.
There have not been any unwanted side effects seen with the overdosage of Lucrin.

While you are being given Lucrin

Things you must do

When Lucrin is first started, there may be a temporary increase in some hormones. This may cause an increase in pain or other symptoms of the cancer in the first weeks. If this happens, see your doctor.
If symptoms include difficulty urinating, a feeling of weakness or numbness in the lower limbs, you should notify your doctor immediately.
These symptoms usually only happen with the first treatment with this medicine; you should not experience them with future treatments.
Keep all of your doctor’s appointments so that your progress can be checked.
Your doctor may continue to monitor your hormone levels throughout your course of treatment.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Lucrin.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon that you are taking this medicine.
If you are about to have any blood tests, tell your doctor that you are taking this medicine.
It may interfere with the results of some tests.
If you do not feel well or your condition worsens, tell your doctor.

Things you must not do

Do not use this medicine to treat any other complaints unless your doctor tells you to.
Do not give this medicine to anyone else, even if they have the same condition as you.
Do not use partial doses or combinations of doses to substitute any depot formulations.
Due to differences in the way each presentation of Lucrin Depot works, a partial dose of a higher strength formulation is not equivalent to the same dose of a lower strength formulation and should not be given. Similarly, combining multiple doses of the lower strength formulations should not be used as a substitute for the higher strength formulations.

Things to be careful of

Be careful driving or operating machinery until you know how Lucrin affects you.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.
