Thiotepa: High-Dose for Stem Cell Transplant (Generic Name)
Other Names: Tepandina®
About This Drug
Thiotepa is used to treat cancer in patients who are getting a blood or bone marrow transplant. This drug is given in the vein (IV).
Possible Side Effects (More Common)
- Bone marrow depression. This is a decrease in the number of white blood cells, red blood cells, and platelets. This may raise your risk of infection, make you tired and weak (fatigue), and raise your risk of bleeding.
- Nausea and throwing up (vomiting)
- Loose bowel movements (diarrhea) that may last for a few days
- Soreness of the mouth and throat. You may have red areas, white patches, or sores that hurt.
- Hair loss: Hair loss is often complete scalp hair loss and can involve loss of eyebrows, eyelashes, and pubic hair. You may notice this a few days or weeks after treatment has started.
Possible Side Effects (Less Common)
- Changes in your liver function. Your doctor will check your liver function as needed.
- Effects on the heart: This drug can weaken the heart and lower heart function. Your heart function will be checked as needed. You may have trouble catching your breath, mainly during activities. You may also have trouble breathing while lying down, and have swelling in your ankles.
While you are getting this drug in your vein (IV), you may have a reaction to the drug. Your nurse will check you closely for these signs: fever or shaking chills, flushing, facial swelling, feeling dizzy, headache, trouble breathing, rash, itching, chest tightness, or chest pain. Tell your nurse right away if you have any of these while getting the drug in your IV.
Treating Side Effects
- Drink 6-8 cups of fluids each day unless your doctor has told you to limit your fluid intake due to some other health problem. A cup is 8 ounces of fluid. If you throw up or have loose bowel movements you should drink more fluids so that you do not become dehydrated (lack water in the body due to losing too much fluid).
- Ask your doctor or nurse about medicine that is available to help stop or lessen the loose bowel movements.
- Mouth care is very important. Your mouth care should consist of routine, gentle cleaning of your teeth or dentures and rinsing your mouth with a mixture of 1/2 teaspoon of salt in 8 ounces of water or ½ teaspoon of baking soda in 8 ounces of water. This should be done at least after each meal and at bedtime.
- If you get a rash do not put anything on it unless your doctor or nurse says you may. Keep the area around the rash clean and dry. Ask your doctor for medicine if the rash bothers you.
