Theracys intravesical Warnings

This medication contains live bacteria that have been weakened to decrease the chances of causing an illness. However, this medication has rarely caused very serious, possibly fatal infections. Tell your doctor right away if you develop any signs of infection (e.g., high/persistent fever).

Theracys intravesical Uses

This medication is used to treat a certain type of bladder cancer (carcinoma in situ-CIS) and prevent it from returning. It is also used to prevent another type of bladder cancer (papillary tumor) from returning after surgery to remove it. This medication works by causing the body's defense system (immune system) to become more active.

This form of the medication is not used to prevent tuberculosis.

How to use Theracys intravesical

This medication is given into the bladder through a tube (catheter) by a health care professional as directed by your doctor. This medication is usually given weekly for the first 6 weeks and then less often thereafter as directed by your doctor.

Do not drink any fluids for 4 hours before treatment. The medication is left in the bladder for up to 2 hours and then released by urinating. Follow your doctor's instructions carefully. There may be some burning pain when you first urinate. Since the urine contains live bacteria that may infect you or others, you must sit down to urinate for 6 hours after treatment to avoid splashing of the urine. After each time you urinate during this 6-hour period, pour household bleach (about the same amount of bleach as the amount of urine) into the toilet, then wait 15 minutes before flushing. Always wash your hands afterward. Talk to your doctor about other important things you must do to prevent infection.

Drink plenty of fluids after your first urination unless otherwise directed by your doctor. Doing so helps clear the medication from your body.

Nausea, vomiting, loss of appetite, or diarrhea may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
