Bacillus Calmette-Guerin (BCG)

Brand Names

TheraCys® BCG, TICE® BCG (There may be other names for this medication.)

How is BCG Administered?

Before receiving BCG, you should avoid drinking fluids for 4 hours before treatment. Empty your bladder before treatment begins. Limit how much you drink for 6-10 hours before each treatment, and for 2 hours after each treatment. Otherwise, drink plenty of water.

BCG is given by intravesicular infusion. This means that the BCG is placed directly into your bladder through a catheter (a thin, flexible tube) that is inserted into the bladder through your urethra. The catheter is clamped to keep the medication in the bladder. You may be asked to change positions so that the BCG will reach all areas of the bladder. After about 2 hours, (your doctor will set your schedule), the clamp is removed and the BCG will drain out of your bladder. The catheter is removed. Treatments are usually given once a week for 6 weeks, then once a month for 6-12 months.
