1. What is Detimedac and what is it used for

Dacarbazine, the active substance in Detimedac, belongs to a group of cytotoxic medicines. These medicines affect the development of cancer cells.
Detimedac is used to treat cancers such as:

• advanced malignant melanoma (skin cancer)
• Hodgkin's disease (malignant lymphoma)
• soft tissue sarcoma (malignant tumor of muscle tissue, fat tissue, fibrous tissue, blood vessels or other supporting tissues). Detimedac may be used in combination with other cytotoxic medicines.

2. Important information before taking Detimedac

When not to take Detimedac

leukopeniaand/or thrombocytopenia);liver or kidney disease;pregnant or breastfeeding;

Warnings and precautions

Before starting treatment with Detimedac, the patient should discuss it with their doctor or pharmacist.
Before each administration of Detimedac, a blood test is performed to assess whether the patient's blood cell count is sufficient to administer Detimedac. The liver and kidney function are also evaluated.

Detimedac and other medicines

The patient should inform their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
It is not recommended to take any therapeutic treatment without first informing the doctor, as there may be interactions between Detimedac and other medicines.
In particular, the patient should inform their doctor or pharmacist if they are being treated with any of the following therapies:

• Radiation therapy or other medicines used to inhibit the growth of cancer tumors (chemotherapy). The use of these medicines with Detimedac may increase the harmful effect on the bone marrow.
• Other medicines metabolized by the liver enzyme system called cytochrome P450.
• Methoxsalen - used in skin diseases such as psoriasis and eczema. The use of Detimedac with methoxsalen may increase sensitivity to sunlight (phototoxicity).
• Phenytoin - concurrent use of Detimedac and phenytoin increases the risk of seizures (convulsions).
• Cyclosporine or tacrolimus - these medicines may weaken the immune system.
• Fotemustine - Detimedac should not be used until at least one week after administration of fotemustine, to avoid lung damage.

During chemotherapy, the patient should avoid taking medicines that may damage the liver (e.g., diazepam, imipramine, ketokonazole, or carbamazepine).
The doctor will decide whether the patient should take medicines that improve blood circulation and will check the patient's blood clotting.
Vaccination recommendations vary depending on the type of vaccine:

• Yellow fever vaccine - the patient should not be given the yellow fever vaccine while being treated with Detimedac.
• Live vaccines - the patient should not be given live vaccines while being treated with Detimedac, as Detimedac may lower immunity and increase the patient's susceptibility to severe infections.
• Inactivated vaccines - the patient may be given inactivated vaccines while being treated with Detimedac.

Detimedac with food, drink, and alcohol

The patient should not consume alcohol during chemotherapy.

Pregnancy, breastfeeding, and fertility

Detimedac should not be administered if the patient is pregnant, suspects they may be pregnant, or plans to have a child.
The patient should not breastfeed during treatment with Detimedac.
During treatment with Detimedac, the patient should use effective contraception. Men should continue to use effective contraception for at least 6 months after the end of treatment with Detimedac.

Driving and using machines

Dacarbazine may affect the patient's ability to drive and use machines due to the possibility of side effects on the central nervous system (affecting the brain and spinal cord) or the possibility of nausea and vomiting; however, there is no reason to stop driving or using machines between treatment cycles, unless the patient has dizziness and feels unsteady.

3. How to take Detimedac

This medicine should always be taken according to the doctor's instructions, a specialist in oncology or hematology (the field of blood diseases), with equipment that allows for regular monitoring of all clinical symptoms during and after treatment.
Dacarbazine is a light-sensitive substance. The doctor or nurse responsible for administering the medicine will ensure that dacarbazine is administered with protection from daylight. .

Administration of Detimedac

Detimedac will be administered by a doctor or nurse through intravenous infusion (in intravenous infusion) - the infusion will last from 20 to 30 minutes.
Detimedac 500 mg and Detimedac 1000 mg powder should be dissolved in 50 ml of water for injection just before administration. The resulting solution should be diluted in 200-300 ml of isotonic sodium chloride solution or 5% glucose solution.

Dose of Detimedac

The doctor will determine the dose to be administered to the patient. The dose depends on the type of cancer and the stage of the disease, body surface area (m²), blood morphology results, and other anticancer medicines or therapies used at the same time. The treating doctor will determine the duration of treatment with this medicine for each patient.
The doctor may change the dose and frequency of administrationbased on blood test results, the patient's overall condition, other therapies, and the patient's response to Detimedac. If the patient has any questions about treatment, they should consult their doctor, pharmacist, or nurse.
Metastatic melanoma
The recommended dose is 200-250 mg per m² of body surface area, once a day. This dose is administered for 5 days in a row every 3 weeks. The medicine is administered as a rapid intravenous injection or slow intravenous infusion lasting 15-30 minutes.
Another option is to administer a single large dose of 850-1000 mg per m² of body surface area once every 3 weeks. This dose will be administered as a slow intravenous infusion.
Hodgkin's lymphoma
The recommended dose is 375 mg per m² of body surface area, every 15 days. The patient will also receive doxorubicin, bleomycin, and vinblastine (this combination of medicines is called the ABVD regimen). This dose will be administered as a slow intravenous infusion.
Soft tissue sarcoma
The recommended dose is 250 mg per m² of body surface area, once a day. This dose is administered for 5 days in a row every 3 weeks. The medicine is administered as a slow intravenous infusion lasting 15-30 minutes.
The patient will also receive doxorubicin (this combination is called the ADIC regimen).

Patients with kidney or liver disorders

In patients with mild or moderate kidney or liver disorders, it is usually not necessary to reduce the dose of this medicine. In patients with disorders of both kidneys and liver, the metabolism and excretion of the medicine will take longer. The doctor may recommend a lower dose for the patient.

Elderly patients

There are no special recommendations for the use of this medicine in elderly patients.

Use in children

Until additional data are available, there are no recommendations for the use of dacarbazine in children.

Administration of a higher than recommended dose of Detimedac

The patient should immediately inform their doctor or nurse if they think they have been given a higher dose of Detimedac than recommended.

• In case of suspected overdose, the patient's blood cell count will be checked, and corrective measures may be taken, such as blood transfusion.
• Overdose can cause severe bone marrow damage (toxicity). It may lead to complete loss of bone marrow function (aplastic anemia). It may occur as a delayed reaction, even after two weeks.

If the patient has any further doubts about the use of this medicine, they should consult their doctor or pharmacist.

Information intended for healthcare professionals only:
Dacarbazine is an anticancer medicine. Before starting treatment, local guidelines for handling cytotoxic medicines should be consulted.
Containers containing dacarbazine should only be opened by trained personnel; as with other cytotoxic medicines, exposure of personnel to the medicine should be avoided.
Exposure to cytotoxic medicines should be avoided during pregnancy. The infusion solution should be prepared in a designated area; appropriate procedures should be performed over a washable tray or a single-use, absorbent paper covered with a protective film against permeation.
Appropriate protective eyewear, single-use gloves, face masks, and single-use aprons should be used.
Syringes and infusion sets should be assembled carefully to avoid leakage (it is recommended to use "luer lock" tips).
After completion of work, each surface that may have been contaminated should be carefully cleaned, and hands and face should be washed.
In case of spillage, personnel should wear single-use gloves, face masks, protective eyewear, and single-use aprons, and remove the spilled substance using absorbent material available for this purpose on site. The work surface should then be cleaned, and contaminated material should be placed in a special bag or container for cytotoxic waste or sealed for incineration.
Prepared solutions should be protected from light during administration (using light-protective infusion sets).
