Leuprorelin acetate
Read all of this leaflet carefully before you start using this medicine because it contains important information for you.
Contents of the pack
Leuprorelin GP-Pharm is a vial containing a white powder, which is reconstituted as a suspension for injection into a muscle. Leuprorelin GP-Pharm contains the active substance leuprorelin (also known as leuprolide), which belongs to a group of medicines called gonadotropin-releasing hormone (LHRH) agonists, which are medicines that reduce testosterone (a sex hormone).
Your doctor has prescribed Leuprorelin GP-Pharm for:
Your estrogen levels must have been adequately suppressed with Leuprorelin GP-Pharm before starting treatment with an aromatase inhibitor such as exemestane and must be monitored every three months during combined treatment with Leuprorelin GP-Pharm and an aromatase inhibitor (see the section "Warnings and precautions" below for more information).
Warnings and precautions
Consult your doctor or pharmacist before starting to take Leuprorelin GP-Pharm.
Tell your doctor if you suffer from any of the following symptoms:
Men and women
Only men
Only women
In children:
In girls with central precocious puberty
Using Leuprorelin GP-Pharm with other medicines
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines. It may still be suitable to use Leuprorelin GP-Pharm; your doctor will decide what is suitable for you.
Leuprorelin GP-Pharm may interfere with certain medications used to treat heart rhythm problems (e.g., quinidine, procainamide, amiodarone, and sotalol) or may increase the risk of heart rhythm problems when used with other medications (e.g., methadone (used for pain relief and for detoxification from other medications), moxifloxacin (an antibiotic), antipsychotics used to treat serious mental illnesses).
Pregnancy and breastfeeding
Leuprorelin GP-Pharm is contraindicated during pregnancy. Spontaneous abortions may occur if this medicine is administered during pregnancy.
It is not known whether leuprorelin acetate is excreted in breast milk, therefore, Leuprorelin GP-Pharm should not be administered to women or girls who are breastfeeding.
Driving and using machines
Visual disturbances and dizziness may occur during treatment. If you are affected, do not drive or operate machinery.
Leuprorelin GP-Pharm containsless than 23 mg of sodium (1 mmol) per dose; this is, essentially “sodium-free”.
Leuprorelina GP-Pharm should only be administered by your doctor or nurse. They will be responsible for preparing the product.
Adults and elderly:
The recommended dose of Leuprorelina GP-Pharm is one injection once a month. The powder is reconstituted to form a suspension that is administered as an intramuscular injection (in a muscle) once a month (approximately every 28-33 days).
The injection site should be varied at regular intervals.
Leuprorelina GP-Pharm should only be administered intramuscularly. It should not be administered by any other route.
The treatment regimen will be decided by your doctor.
If you have endometriosis or uterine fibroids, you will be given an injection of Leuprorelina GP-Pharm for a period of up to 6 months at most.
If you have breast cancer, you will be given Leuprorelina GP-Pharm once a month in combination with tamoxifen or an aromatase inhibitor. Before starting treatment with an aromatase inhibitor or tamoxifen, you must have received at least two injections of Leuprorelina GP-Pharm with a one-month interval between each injection.
If you are given Leuprorelina GP-Pharm to preserve ovarian function while receiving chemotherapy, you will normally be given an injection of Leuprorelina GP-Pharm two weeks before starting chemotherapy and then every month during the duration of your chemotherapy treatment.
Use in children:
Treatment of children should be under the general supervision of a pediatric endocrinologist.
Dose adjustment should be done individually.
The recommended starting dose depends on body weight:
Unless your doctor tells you otherwise, 2 ml of Leuprorelina GP-Pharm (3.75 mg of leuprorelin acetate) will be administered once a month as a single intramuscular injection.
Taking into account the clinical activity of central precocious puberty in these rare cases, the following procedure should be followed:
Unless your doctor tells you otherwise, 1 ml of Leuprorelina GP-Pharm (1.88 mg of leuprorelin acetate) will be administered once a month as a single intramuscular injection. The rest of the suspension should be discarded. Your doctor will monitor the child's weight gain.
Depending on the progression of central precocious puberty, your doctor may increase the dose if inadequate suppression is observed (e.g., vaginal bleeding). Your doctor will determine the minimum effective dose through a blood test.
The duration of treatment depends on the clinical symptoms at the start of treatment or during treatment and is decided jointly between the treating doctor, the legal guardian, and, if appropriate, the treated child. Your doctor will determine the child's bone age at regular intervals.
In girls with bone maturation of more than 12 years and boys with bone maturation of more than 13 years, your doctor will assess stopping treatment based on the clinical effects on your child.
In girls, pregnancy should be ruled out before starting treatment. Generally, pregnancy cannot be excluded during treatment. In these cases, consult your doctor.
Treatment is long-term and is adjusted individually. Please agree with your doctor that the administration of Leuprorelina GP-Pharm be done as precisely as possible at regular monthly intervals. An exceptional delay of the injection date by a few days (30 ± 2 days) does not affect the outcome of the treatment.
If you use more Leuprorelina GP-Pharm than you should
This is unlikely, as the doctor or nurse will know what the correct dose is. Nevertheless, if you suspect that you have received more medication than you should, inform your doctor immediately so that the necessary measures can be taken.
In case of overdose or accidental ingestion, consult the Toxicological Information Service, tel: 91 562 04 20.
If you miss a dose of Leuprorelina GP-Pharm
It is essential that you do not miss a dose of Leuprorelina GP-Pharm. As soon as you realize that you have missed an injection, contact your doctor, who will administer the next injection.
Only for women:if you miss an injection of Leuprorelina GP-Pharm, intermenstrual bleeding or ovulation with the possibility of conception may occur. If you think you may be pregnant, you should stop using Leuprorelina GP-Pharm and contact your doctor immediately.
If you interrupt treatment with Leuprorelina GP-Pharm
Since medical treatment involves the administration of Leuprorelina GP-Pharm for a long period, interrupting treatment may result in a worsening of symptoms related to the disease. Therefore, you should not interrupt treatment prematurely without your doctor's permission.
If you are given Leuprorelina GP-Pharm for the treatment of breast cancer, you should not interrupt treatment with Leuprorelina GP-Pharm while taking an aromatase inhibitor or tamoxifen. If you are going to interrupt treatment with Leuprorelina GP-Pharm, your treatment with the aromatase inhibitor should also be interrupted within 1 month from the last injection of Leuprorelina GP-Pharm.
If you have any other questions about the use of this medication, ask your doctor or pharmacist.
Like all medicines, Leuprorelina GP-Pharm can cause side effects, although not everyone gets them.
Tell your doctor immediately if you notice any of the following symptoms:
During the first few weeks of treatment, a transient worsening of your condition may occur, but it should improve with continued treatment.

As with other medications in this class: if you have an existing pituitary lesion, there may be a higher risk of bleeding in the area, which could cause permanent damage.
Not known (frequency cannot be estimated from available data):
Seizures, lung inflammation, lung disease.
Idiopathic intracranial hypertension (increased pressure around the brain characterized by headaches, double vision, and other visual symptoms, ringing or buzzing in one or both ears).
Notes:
Generally, the occurrence of vaginal bleeding during continued treatment (after the possible withdrawal bleeding in the first month of treatment) should be evaluated as a potential sign of underdosing. If vaginal bleeding occurs, inform your doctor.
