Leuprorelin GP-Pharm Depot Trimestral is a vial containing a white powder, which is reconstituted as a suspension for injection into a muscle. This medicine 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 this medicine for the palliative treatment of advanced prostate cancer.

2. What you need to know before you use Leuprorelin GP-Pharm Depot Trimestral

• If you are allergic (hypersensitive) to LHRH, LHRH agonists or any of the other ingredients of this medicine (listed in section 6). An allergic reaction may appear as a skin rash, itching, difficulty breathing or swelling of the face, lips, throat or tongue.
• If you have undergone orchiectomy (removal of the testicles).
• If you are a woman or a child.
• This medicine must not be used alone (as monotherapy) for the treatment of prostate cancer when the spinal cord is compressed or the cancer has spread to the spinal cord.

Warnings and precautions

• Talk to your doctor or pharmacist before starting this medicine.

• It is possible that your disease may worsen during the first few weeks of treatment, but it should improve with continued treatment. The signs and symptoms include: temporary increase in testosterone (male hormone), hot flashes, bone pain, nervous system disorders (including depression) or urinary obstruction.
• If you think you are experiencing an allergic reaction (shortness of breath, asthma, rhinitis, swelling of the face, urticaria, skin rash), stop taking this medicine and inform your doctor.
• Tell your doctor if you have a risk of or are already suffering from any of the following diseases, as you may need more frequent check-ups:
• • Bruises or unexplained bleeding or if you feel unwell. Although rare, these can be symptoms of changes in the number of red or white blood cells.
  • Metabolic disease
  • Heart problems or palpitations
  • Diabetes.
• Your doctor should be informed of any personal medical history of pituitary adenoma (non-cancerous tumor of the pituitary gland). Cases of pituitary apoplexy (partial loss of pituitary tissue) have been described after the initial administration of this type of medicine to patients with pituitary adenoma. Pituitary apoplexy may manifest as sudden headache, meningism, vision disorders or altered vision, including blindness, and occasionally a decrease in the level of consciousness.
• Your doctor should know if you suffer from a coagulation disorder, thrombocytopenia or if you are being treated with anticoagulants. Your liver function may need to be monitored, as liver disorders and jaundice (yellowing of the eyes and skin) have been described with the administration of leuprorelin.

• Depression has been reported in patients undergoing treatment with this medicine, which can be severe. If you are taking this medicine and feel depressed, inform your doctor.
• A reduction in bone density (fragile or thinner bones) has been described after administration of leuprorelin. Your doctor may consider adding an anti-androgen to the treatment with this medicine. In this case, your doctor will be alert to detect the presence of vein inflammation (thrombophlebitis) and other signs of coagulation disorders and edema (swelling of hands, feet or ankles) that are more likely to occur when anti-androgenic treatment is added to this medicine.
• Tell your doctor if you feel pressure on the spinal cord and/or present urinary disorders and/or hematuria (blood in the urine); in such a case, your doctor will discuss the need for additional treatments to prevent neurological complications (e.g., tingling in hands and feet, paralysis) or urethral obstruction (the duct that connects the bladder to the outside of the body). You will be closely monitored during the first few weeks of treatment.
• Patients may experience metabolic changes (e.g., glucose intolerance or worsening of existing diabetes), weight changes, and cardiovascular disorders.
• Patients with metabolic or cardiovascular disease, and especially those with a history of congestive heart failure (a disease in which the heart can no longer pump enough blood to the rest of the body), should be monitored during treatment with leuprorelin.
• Ask your doctor, pharmacist, or nurse if you have fatty liver.
• During treatment, some blood tests will be performed to check if this medicine is effective.
• You may experience a loss of interest in sexual relations, hot flashes, and occasionally a reduction in the size and function of the testicles.
