Thiotepa is used to treat cancer. It works by slowing or stopping the growth of cancer cells. Thiotepa is often given into the bladder to treat bladder cancer.
This medication is given by injection into a vein by a health care professional, usually once a week or as directed by your doctor. Sometimes, thiotepa is injected directly into the tumor. Tell your doctor or nurse right away if you experience pain, burning, or redness at the injection site.
For treatment of bladder cancer, thiotepa is usually given into the bladder through a tube (catheter). Your doctor may direct you to limit fluids for 8 to 12 hours before the medication is given. The solution is usually left in place for 2 hours and then drained out through the bladder tube. Your doctor may direct you to change positions every 15 minutes while the solution is in your bladder to make sure the solution treats all parts of your bladder.
The dosage and how often the medication is given is based on your medical condition and response to treatment. Your doctor will do blood tests (complete blood count) to find the right dose for you. Your next dose may need to be rescheduled if your white blood cell count or platelets are too low.

Pain/redness at the injection site, dizziness, headache, blurred vision, fever, nausea, vomiting, stomach/abdominal pain, or loss of appetite may occur. Changes in diet such as eating several small meals or limiting activity may help lessen some of these effects. In some cases, drug treatment may be necessary to prevent or relieve nausea and vomiting. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Temporary hair loss is another common side effect. Normal hair growth should return after treatment has ended.
