Skin Cancer Home > DTIC-Dome Warnings and Precautions
Discuss your medical history with your healthcare provider before beginning treatment with DTIC-Dome. Although this can be an effective form of chemotherapy, it may not be the best option for people who have problems with their liver or kidneys. Safety precautions with DTIC-Dome also include warnings of serious drug interactions, allergic reactions, and dangerously low blood cell counts.
You should talk with your healthcare provider prior to receiving DTIC-Dome® (dacarbazine) if you have:
- Liver disease, such as hepatitis, cirrhosis, or liver failure
- Kidney disease, such as kidney failure (renal failure)
- Any allergies, including to foods, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant
You should also tell your healthcare provider about all other medications you are taking, including prescription and nonprescription medicines, vitamins, and herbal supplements.
Specific Precautions and Warnings for DTIC-Dome
Some warnings and precautions to be aware of prior to receiving this medication include the following:
- Like other chemotherapy medicines, DTIC-Dome can cause significant bone marrow depression, a condition in which the bone marrow does not make adequate amounts of blood cells. This can lead to serious problems, such as:
- Your blood cell counts will be monitored closely using blood tests throughout treatment. Your healthcare provider may recommend you miss a dose, or stop treatment altogether, if your blood cells counts become too low. Let your healthcare provider know if you have any signs of bone marrow depression, such as:
- Unusual bleeding or bruising
- Signs of infection, such as fever, chills, and aches and pains
- Signs of anemia, such as tiredness, shortness of breath, or paleness.
- This medication can cause liver damage. Although rare, the liver damage from DTIC-Dome has been reported to cause death. Let your healthcare provider know if you develop signs of liver problems, such as:
- Yellowing of the skin or whites of the eyes (jaundice)
- Dark urine
- Upper-right abdominal (stomach) pain.
- Some people may experience a life-threatening allergic reaction known as anaphylaxis after receiving DTIC-Dome. Let your healthcare provider know right away if you develop signs of an allergic reaction, such as:
- A rash
- Swelling of the mouth, face, or throat
- Difficulty breathing or swallowing.
- This medication can cause skin irritation and tissue damage if it leaks from the vein during administration and comes into contact with body tissue. Tell your healthcare provider right away if you experience pain, stinging, burning, redness, or swelling at your injection site. He or she may be able to relieve some of the pain by applying hot packs to the area.
- This drug caused cancer when given to rats and mice. It may increase the risk for developing other types of cancer in humans as well.
- People receiving DTIC-Dome may experience significant nausea and vomiting, especially with the first few doses. Vomiting may last 1 to 12 hours, but usually gets better after the first 1 to 2 days of treatment. Limiting the amount of food you consume for four to six hours before receiving your dose can help reduce this symptom. Let your healthcare provider know if you experience extreme or persistent nausea and vomiting, especially if you cannot keep down liquids, or if your symptoms persist for more than 12 hours.
- You may be more sensitive to the sun during treatment. Make sure to wear sunscreen and protective clothing, such as a long-sleeve shirt and hat, if you will be outside.
- DTIC-Dome may react with a number of other medications (see DTIC-Dome Drug Interactions).
- DTIC-Dome is a pregnancy Category C medication, which means it may not be safe for use during pregnancy (see DTIC-Dome and Pregnancy).
- It is not known whether DTIC-Dome passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to receiving the drug (see DTIC-Dome and Breastfeeding).
