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.
Your doctor may continue to monitor your testosterone levels to ensure that acceptable suppression of the secretion of hormones from the testes is maintained 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.
Keep all of your doctor’s appointments so that your progress can be checked.
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 or pharmacist tells you to.
Do not give this medicine to anyone else, even if they have the same condition as you.
Do not use fractional doses or combinations of doses to substitute any depot formulations.
Due to different release characteristics of each presentation of Lucrin Depot, a fractional dose of the 3-month depot, 4-month depot or 6- month depot formulation is not equivalent to the same dose of the monthly formulation (Lucrin Depot 7.5 mg PDS) and should not be given. Similarly, fractional doses of the 30 mg or 45 mg formulations should not be used as a substitute for the 30 mg or 22.5 mg and multiples of the 7.5 mg presentation should not be used as a substitute for the 22.5 mg, 30 mg or 45 mg 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.
Lucrin injection should be stored in a refrigerator (2°C to 8°C). Do not freeze. Protect from light.
Lucrin PDS Injections should be kept in a cool, dry place where the temperature stays below 25°C.
Do not store it or any other medicine in the bathroom, near a sink, or on a windowsill. Do not leave it in the car.
Heat and dampness can destroy some medicines.
Keep it where children cannot reach it.
A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
If your doctor or pharmacist tells you to stop taking this medicine, or the medicine has passed its expiry date, ask your pharmacist what to do with any medicine that is left over.
