TheraCys

Generic Name:BCG Vaccine

TheraCys is a prescribed medication used commonly known as BCG vaccine. 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 or immune system to become more active. This form of the medication is not used to prevent tuberculosis. This medication is injected directly into the bladder, where it causes inflammation and increases certain white blood cells known as natural killer cells. These killer cells act to destroy invading cells such as tumor cells in the bladder.

How to Use TheraCys BCG Injections

  • This medication is given into the bladder through a tube (catheter) as directed by your doctor. Do not give this medication by injection.
  • 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.
  • 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.
