How is thiotepa given?
Thiotepa is injected into a vein through an IV, 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.
If any of this medicine accidentally gets on your skin, wash it thoroughly with soap and warm water.
Thiotepa is usually given once every 1 to 4 weeks. Follow your doctor's dosing instructions very carefully.
Thiotepa can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often during treatment and for at least 3 weeks after you stop receiving thiotepa. Your cancer treatments may be delayed based on the results of these tests.
What happens if I miss a dose?
