Patient leaflet - Dacarbazine 100 mg powder for solution for injection/infusion
1. What Dacarbazine is and what it is used for
Dacarbazine belongs to the group of medicines known as cytostatic agents. These agents influence the growth of cancer cells.
Dacarbazine has been prescribed by your doctor for the treatment of cancer, such as:
- advanced malignant melanoma (skin cancer)
- Hodgkin’s disease (cancer of the lymphatic tissue)
- soft tissue sarcoma (cancer of muscles, fat, fibrous tissue, blood vessels or other supporting tissue of the body).
Dacarbazine can be used in combination with other cytostatic agents.
2. What you need to know before you are given Dacarbazine
You will not be given Dacarbazine if:
- you are allergic to dacarbazine or any of the other ingredients of this medicine (listed in section 6)
- the number of white blood cells and/or platelets in your blood is too low (leukopenia and/or thrombocytopenia)
- you have a severe liver or kidney disease
- you are pregnant or breast-feeding.
Warnings and precautions
Talk to your doctor or pharmacist before you are given Dacarbazine.
Before each administration you will have blood tests to check that you have enough blood cells to receive this medicine. Your liver and kidney function will also be monitored.
You should not have a live vaccine if you are having Dacarbazine. This is because Dacarbazine may weaken your immune system and make you more likely to catch a serious infection.
You should not use fotemustine if you are being treated with Dacarbazine.
Other medicines and Dacarbazine
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
It is not advisable to use any medical treatment without telling your doctor as there may be interactions between Dacarbazine and other medicines.
In particular, tell your doctor or pharmacist if you are using or are being treated with any of the following:
- Radiation treatment or other medicines to reduce tumour growth (chemotherapy). Using these medicines with Dacarbazine can increase the damage to your bone marrow
- Other medicines that are metabolised by a system of liver enzymes called cytochrome P450
- Methoxypsoralen (for skin problems such as psoriasis and eczema) – Having Dacarbazine with methoxypsoralen can make you more sensitive to sunlight (photosensitisation)
Phenytoin (used to treat seizures) – Using Dacarbazine and phenytoin at the same time may make it more likely for you to have fits (convulsions)
- Cyclosporine or tacrolimus (used to lower the body’s immune reactions) – These medicines may weaken your immune system
- Fotemustine (used for treatment of skin cancer) – Using Dacarbazine and fotemustine at the same time may lead to damage to your lungs
- Medicines that can cause liver damage, e.g. diazepam (used to treat anxiety, muscle spasms and convulsions), imipramine (used to treat symptoms of depression), ketoconazole (used to treat fungal infections), carbamazepine (used to prevent fits, modify some types of pain or to control mood disorders) should be avoided during chemotherapy
- Anticoagulants (medicines used to prevent formation of blood clots) – Your doctor will decide whether these medicines will be given to you and will check the clotting tendency of your blood.
You should not have a live vaccine if you are having Dacarbazine and during 3 months following completion of treatment with Dacarbazine. This is because Dacarbazine may weaken your immune system and make you more likely to catch a serious infection.
You may have a ‘killed’ or inactivated vaccine if you are having Dacarbazine.
Dacarbazine with alcohol
During chemotherapy you should not drink alcohol.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine. The medicine could harm your unborn baby.
Do not use dacarbazine if you are pregnant, think you may be pregnant or are planning to have a baby.
Do not breast-feed while you are being treated with Dacarbazine.
Women of childbearing potential/contraception in men and women If you are a woman and wish to become pregnant, you should talk to your doctor as he or she can refer you to a specialist before the planned start of treatment and after treatment.
If you are a man, you are advised to seek advice on sperm preservation before the planned start of treatment.
Women of childbearing potential should use effective contraceptive measures while being treated with dacarbazine and for 6 months following completion of treatment. Men should use effective contraceptive measures and not father a child while being treated with dacarbazine and for 3 months following completion of treatment.
Driving and using machines
Your ability to drive or operate machines may be influenced because of central nervous side effects (effects on the brain and nerves) or feeling sick and being sick; but there is no reason why you cannot drive or use machines between courses of therapy with this medicine unless you feel dizzy or unsure of yourself.
3. How to use Dacarbazine
This medicine will be given to you under the direction of a doctor specialised in oncology (cancer treatment) or haematology (the study of diseases of the blood). You will be monitored regularly, during and after your treatment, for any signs of side effects.
Dacarbazine is a substance sensitive to light exposure.
The doctor or nurse giving you this medicine will make sure that dacarbazine will be protected from exposure to daylight during administration.
How much Dacarbazine you will be given
Your doctor will calculate the dose you will be given.
This will depend on the type of cancer you have and how advanced it is, your body surface area (m²), blood counts and other anticancer medicines or treatments you are currently having. The treating physician will also decide individually how long this medicine will be given to you.
Your doctor may change the dose and frequency of dosing depending on your blood test results, your general condition, further therapies and your response to this medicine. If you have any questions about your treatment, ask your doctor, nurse or pharmacist.
Skin cancer (metastatic malignant melanoma)
The usual dose is 200 – 250 mg per m² body surface area, once a day. You are given this dose 5 days in a row, every 3 weeks. It will be given as a fast injection into your vein or as a slow infusion into your vein lasting 15 – 30 minutes. Alternatively, you can be given one larger dose of 850 mg per m² body surface area, every 3 weeks. This will be given as a slow infusion into your vein.
Cancer of the lymphatic tissue (Hodgkin’s disease)
The usual dose is 375 mg per m² body surface area, every 15 days. You will also be given medicines called doxorubicin, bleomycin and vinblastine (this combination is called the ABVD regimen). It will be given as a slow infusion into the vein.
Cancer of muscles, fat, fibrous tissue, blood vessels or other supporting tissue of the body (soft tissue sarcoma)
The usual dose is 250 mg per m² body surface area, once a day. You are given this dose 5 days in a row, every 3 weeks. It will be given as a slow infusion into the vein lasting 15 – 30 minutes.
You will also be given a medicine called doxorubicin (this combination is called the ADIC regimen).
Patients with kidney or liver problems
If you have either mild or moderate kidney or liver problems, you do not usually need to have less of this medicine. If you have both kidney and liver problems, your body will take longer to use the medicine and remove it from your system. Your doctor may give you less of this medicine.
Use in children
No special recommendations for the use of this medicine in children can be given to your doctor until further data become available.
If you have been given more Dacarbazine than you should
If you have been given too much Dacarbazine, this may cause a severe decline in your blood cells. It may lead to a complete loss of function of your bone marrow. Possible symptoms include signs of infections, bruising due to an increased bleeding tendency or fatigue. This can be delayed by up to 2 weeks.
If you think you have been given too much Dacarbazine, tell your doctor or nurse straight away. The number of blood cells will be checked and supportive measures such as transfusions may be required.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
