Find out what dacarbazine is, how you have it and other important information about taking dacarbazine for melanoma.
Dacarbazine (also called DTIC) is a chemotherapy drug. You might have it as part of your treatment for:
- soft tissue sarcoma
- Hodgkin lymphoma
Dacarbazine belongs to a group of chemotherapy drugs called alkylating agents. It works by sticking to the cancer cell's DNA and damaging it.
The DNA is the genetic code that controls everything the cell does. If the DNA is damaged, the cancer cell cannot divide into 2 new cells.
How you have it
Dacarbazine is a yellow liquid that you have into your bloodstream. You might have it as a slow injection or as a drip. It can take up to an hour to have.
Into your bloodstream
You have the treatment through a drip into your arm or hand. A nurse puts a small tube (a cannula) into one of your veins and connects the drip to it.
You might need a central line. This is a long plastic tube that gives the drugs into a large vein, either in your chest or through a vein in your arm. It stays in while you’re having treatment, which may be for a few months.
When you have it
You can have dacarbazine alone or in combination with other chemotherapy drugs. Your treatment plan (regimen) will depend on the type, and the stage of your cancer.
You usually have dacarbazine as a course of several cycles of treatment. A cycle of treatment is the time between 1 round of treatment and the start of another. This is to allow your body to recover.
You have blood tests before and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
Cancer drugs can interact with some other medicines and herbal products. Tell your doctor or pharmacist about any medicines you are taking. This includes vitamins, herbal supplements and over the counter remedies.
Pregnancy and contraception
This treatment might harm a baby developing in the womb. It is important not to become pregnant or father a child while you're having treatment and for a few months afterwards. Talk to your doctor or nurse about effective contraception before starting treatment.
Don’t breastfeed during this treatment because the drug may come through into your breast milk.
You are more at risk of developing a blood clot during treatment. Drink plenty of fluids and keep moving to help prevent clots.
Always tell other doctors, nurses, pharmacists or dentists that you’re having this treatment if you need treatment for anything else, including teeth problems.
Don’t have immunisations with live vaccines while you’re having treatment and for up to 12 months afterwards. The length of time depends on the treatment you are having. Ask your doctor or pharmacist how long you should avoid live vaccinations.
In the UK, live vaccines include rubella, mumps, measles, BCG, yellow fever and the shingles vaccine (Zostavax).
- have other vaccines, but they might not give you as much protection as usual
- have the flu vaccine (as an injection)
Contact with others who have had immunisations - You can be in contact with other people who have had live vaccines as injections. Avoid close contact with people who have recently had live vaccines taken by mouth (oral vaccines) such as the oral typhoid vaccine.
If your immune system is severely weakened, you should avoid contact with children who have had the flu vaccine as a nasal spray. This is for 2 weeks following their vaccination.
Babies have the live rotavirus vaccine. The virus is in the baby’s poo for about 2 weeks and could make you ill if your immunity is low. Get someone else to change their nappies during this time if you can. If this isn't possible, wash your hands well after changing their nappy.
