1. What is Diphereline 0.1 mg and what is it used for

This medicine contains triptorelin. Triptorelin belongs to a group of medicines known as gonadotropin-releasing hormone (GnRH) analogues. One of its actions is to reduce the production of sex hormones in the body.
Long-term administration of triptorelin, after initial stimulation, leads to inhibition of gonadotropin secretion, which in turn leads to inhibition of gonadal function (testes or ovaries).
Prostate cancer with metastases
Administration of a single dose of the medicine may initially increase testosterone levels. Continued treatment leads to a decrease in steroid hormone levels within 2-3 weeks to a level equivalent to castration. This condition depends on the duration of treatment.
Infertility in women
Long-term treatment with the preparation leads to inhibition of gonadotropin secretion. This treatment improves the course of folliculogenesis, increasing the number of maturing follicles, which leads to an increased number of pregnancies per cycle.
Indications for use of Diphereline 0.1 mg

• Prostate cancer with metastases Initial treatment before using a prolonged-release form. Patients who have not previously undergone other hormone therapy respond better to triptorelin treatment.
• Infertility in women Adjunctive treatment in combination with gonadotropin administration (hMG, FSH, hCG) to induce ovulation, in preparation for in vitro fertilization and embryo transfer to the uterus.

2. Important information before using Diphereline 0.1 mg

When not to use Diphereline 0.1 mg

• In case of hypersensitivity (allergy) to triptorelin, gonadorelin (GnRH), other GnRH analogues or any of the other ingredients of Diphereline 0.1 mg
• In case of pregnancy or breastfeeding

Warnings and precautions

Before starting treatment with Diphereline 0.1 mg, discuss it with your doctor or pharmacist.
During treatment with Diphereline 0.1 mg, a pituitary tumor (benign tumor) may be revealed, which the patient was not aware of. Symptoms include sudden headache, vomiting, vision disturbances, and eye muscle paralysis.
There have been reports of depression, including severe depression, in patients taking Diphereline 0.1 mg. If depressive moods occur while taking Diphereline 0.1 mg, inform your doctor.
In adults, long-term treatment with triptorelin may cause bone weakness (osteoporosis) associated with an increased risk of bone fractures. Inform your doctor if you have any of the following risk factors, as your doctor may recommend taking bisphosphonates (medicines used to treat osteoporosis) to treat bone loss.
Risk factors may include:

• osteoporosis in the patient or their immediate family;
• alcohol abuse, smoking, malnutrition;
• long-term use of medicines that can cause bone loss, such as those used to treat epilepsy or corticosteroids (such as hydrocortisone, prednisolone).

If seizures occur, inform your doctor immediately. Seizures have been reported in patients taking triptorelin or similar medicines. They occurred in patients with previously diagnosed epilepsy or without it.
Men
At the beginning of treatment, an increase in testosterone levels in the body is observed. This may cause worsening of symptoms related to the tumor. In such a case, contact your doctor. Your doctor may prescribe an additional medicine (anti-androgen) to prevent worsening of these symptoms.
If the patient experiences urinary retention or spinal cord compression due to tumor spread, the doctor will closely monitor the patient during the first few weeks of treatment. In case of difficulty urinating, bone pain, lower limb weakness, or tingling, contact your doctor immediately, who will assess the patient's condition and initiate appropriate treatment.
Triptorelin does not induce further reduction of testosterone levels in patients after orchiectomy (testicle removal).
Results of diagnostic tests of gonadal pituitary and reproductive organ function performed during or after treatment with Diphereline 0.1 mg may be misleading.
Inform your doctor if you have heart or blood vessel disease, including arrhythmias (abnormal heart rhythm) or if you are taking medicines used to treat arrhythmias. The risk of arrhythmias may be increased during treatment with Diphereline 0.1 mg.
Medicines that lower testosterone levels may cause changes in the ECG related to arrhythmias (prolongation of the QT interval).
Inform your doctor if you have diabetes and/or heart disease.
Women
During treatment for infertility, gonadotropins in combination with Diphereline 0.1 mg may cause ovarian enlargement or hyperstimulation, which may cause pelvic and/or abdominal pain and breathing difficulties. In such a case, consult your doctor immediately.

Other medicines and Diphereline 0.1 mg

Tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take.
Men:
Diphereline 0.1 mg may affect the action of other medicines used to treat arrhythmias (e.g., quinidine, procainamide, amiodarone, sotalol) or may increase the risk of arrhythmias when taken with other medicines (e.g., methadone used to treat pain and as part of detoxification in case of drug addiction), moxifloxacin (antibiotic), antipsychotic medicines used to treat severe mental illnesses).

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor before using this medicine.
It must be confirmed that the patient is not pregnant before prescribing Diphereline 0.1 mg.
Diphereline 0.1 mg must not be used during pregnancy and breastfeeding.

Driving and using machines

During treatment, dizziness, fatigue, or vision problems, such as blurred vision, may occur. These symptoms may be side effects of treatment or the underlying disease. If any of these side effects occur, do not drive or operate any machines.

Diphereline 0.1 mg contains sodium

The medicine contains less than 1 mmol (23 mg) of sodium per dose, which means the medicine is considered "sodium-free".

3. How to use Diphereline 0.1 mg

Infertility in women
Administer subcutaneously one dose of the medicine (0.1 mg) per day from the second day of the cycle. After achieving decreased pituitary sensitivity (i.e., around the 15th day from the start of treatment), gonadotropin stimulation is started and continued while administering triptorelin until the day before the scheduled day of hCG administration (chorionic gonadotropin).
Method of preparation of the medicine:
Transfer the solvent to the vial containing the powder. Shake until completely dissolved and administer immediately.
Used syringes should be disposed of in a suitable container for sharp objects. Any remaining medicine should be disposed of.
