How is thiotepa given?

Thiotepa is given as an infusion into a vein, or injected directly into the bladder or other body cavity. A healthcare provider will give you this injection.

When injected into the bladder, you will need to hold the medicine inside your bladder for 2 hours. Tell your caregivers if this causes you a great deal of discomfort. You may need to receive a smaller amount of the medicine to hold it comfortably in your bladder.

Thiotepa is usually given once every 1 to 4 weeks. Follow your doctor's dosing instructions very carefully.

Thiotepa can increase your risk of bleeding or infection. You will need frequent medical tests.

Thiotepa can be dangerous if it gets in your mouth, eyes, or nose, or on your skin. If this happens, wash your skin with soap and water or rinse your eyes with water.

Being treated with thiotepa may cause itching, blistering, peeling, or discoloration (especially in the skin folds of your groin, underarms, or neck). Bathe or shower and wash your skin with soap and water at least 2 times per day for at least 48 hours after each time you receive this medicine.

If you cover the skin with any bandaging, change the dressing and clean the covered skin at 2 times per day for 48 hours after each time you receive thiotepa.

Change your bed sheets every day during treatment.
