Thiotepa belongs to a group of medicines known as cytotoxic agents and is used alone, or in

3. How you will be given Thiotepa

given as eyedrops, or mixed with a gel for application to the skin or instilled into the bladder
through a catheter inserted into the urethra (the tube through which urine is passed).
The dose of Thiotepa and how it is given to you will depend on your condition and your

may need to be repeated at intervals over a period of weeks or months.
You may be given Thiotepa with other drugs or in addition to surgery.
