Thiotepa
About Thiotepa
Thiotepa is an injectable prescription medicine used to treat certain types of cancer, including breast and ovarian cancers. It is also used to prepare patients for bone marrow or stem cell transplants by clearing out existing bone marrow cells to make room for healthy new donor cells.
Because Thiotepa is given as an injection or infusion, your healthcare team will schedule and administer your doses at specific intervals. While you do not need to worry about taking it with food, staying well-hydrated before and after each session is very important. Making simple lifestyle adjustments, such as getting plenty of rest and eating small, frequent meals, can help your body cope with the treatment.
While receiving this medicine, you may experience common side effects like nausea, vomiting, or temporary hair loss. However, you must contact your doctor immediately if you face serious side effects, such as a fever, chills, or unusual bleeding and bruising.
Before starting treatment, talk to your doctor if you have kidney disease, liver damage, or a history of heart problems. Do not take this medicine if you have had a severe allergic reaction to it in the past, have severely reduced bone marrow function, or have previously developed aplastic anemia (a rare but serious failure of the bone marrow to produce blood cells) after receiving Thiotepa or a similar medicine. Tell your doctor if you are receiving other treatments that suppress the bone marrow, such as certain chemotherapy medicines.
Thiotepa can interact with live vaccines and other treatments that weaken your immune system, which can increase your risk of severe infections. You should also consult your doctor if you are pregnant, planning to become pregnant, or breastfeeding, as this medicine can harm an unborn baby.

- Check the Solution: Ensure your nurse inspects the liquid before injection; it should be clear and free of visible floating particles.
- Monitor the Injection Site: Tell your healthcare team immediately if you feel any burning, pain, or swelling where the needle is inserted, as the medicine must not leak into surrounding tissues.
- Avoid Live Vaccines: Do not receive any live vaccines (such as MMR or chickenpox vaccines) during your treatment, as your weakened immune system may not be able to handle them.
- Use Reliable Birth Control: Both men and women must use highly effective birth control during treatment and for at least 6 months after the final dose, or for as long as advised by their treating doctor, to prevent pregnancy.
- Keep Up with Monitoring: Attend all scheduled blood tests so your doctor can monitor your blood cell counts, liver function, and kidney function. In certain patients, your doctor may also check blood (serum) Thiotepa levels to ensure safe and effective dosing.
Drug Interactions
- Other chemotherapy medicines: Combining Thiotepa with other cancer treatments can increase the risk of severe bone marrow suppression and dangerously low blood counts.
- Live vaccines: May cause severe infections because Thiotepa lowers your body's ability to fight off viruses or bacteria.
- Medicines that affect liver enzymes: Some medications can change how your body processes Thiotepa, which may increase the level of the medicine in your blood and lead to more side effects.

Patients Concern
Disease/Condition Glossary
Graft rejection: It is a condition in which a transplant recipient's immune system attacks the transplanted organ or tissue. Symptoms include a decrease in organ function, general discomfort, flu-like symptoms, and uneasiness.
Bone marrow transplantation: A bone marrow transplant is a procedure to replace damaged or diseased bone marrow with healthy bone marrow stem cells.
Breast cancer: It is a type of cancer that develops in the breast when the breast cells begin to grow abnormally. Symptoms of breast cancer include a lump in the breast or tissue thickening which feels different than the normal surrounding tissues, breast pain, redness, swelling, nipple discharge other than breast milk, bloody discharge, unexplained change in shape, size or appearance of the breast, peeling, flaking or scaling of the skin, and a lump or swelling under the arm.
Ovarian Cancer: Ovarian cancer occurs when abnormal cells grow and multiply in the ovaries and fallopian tubes. Signs and symptoms include pain, swelling, or a feeling of pressure in the pelvis or abdomen, frequent or sudden urge to urinate, feeling full or trouble eating, a lump in the pelvic area, gas, bloating, or constipation.
Bladder cancer: It is the growth of tumours in the bladder lining. The most common symptom of bladder cancer is blood in the urine.
Serosal cavity neoplastic disease: Serosal cavity neoplastic disease is the presence of cancer cells in a serosal cavity. A serous cavity, also known as the peritoneal cavity, pleural cavity, or pericardial cavity, is a cavity that is lined with a serous membrane that secretes a lubricating fluid which reduces friction from muscle movement.
Malignant effusions caused by cancerous tumours: It is a condition when fluid collects in the lungs or around the heart caused by cancer cells growing in the pleural space. Symptoms include dry cough, pain, shortness of breath, and a feeling of tightness or chest heaviness.
FAQs
