[BCG Live (Intravesical)]



TheraCys®, BCG Live (Intravesical) contains live, attenuated mycobacteria. Because of the potential risk for transmission, prepare, handle, and dispose of TheraCys as a biohazard material.

BCG is capable of dissemination when administered by the intravesical route. Serious infections, including fatal infections, have been reported in patients receiving Intravesical BCG.


TheraCys, BCG Live (Intravesical) is a freeze-dried preparation made from the Connaught strain of Bacillus Calmette and Guérin, which is an attenuated strain of Mycobacterium bovis.

The BCG organisms in the product are grown on media containing potatoes, glycerine, asparagine, citric acid, potassium phosphate, magnesium sulfate, ferric ammonium citrate, calcium chloride, copper sulfate, and zinc sulfate. Monosodium glutamate is added to the BCG organisms prior to freeze-drying.

Each vial of TheraCys contains 81 mg of freeze-dried BCG. The freeze-dried BCG does not contain any preservative.

One dose of TheraCys consists of one 81mg vial of freeze-dried BCG reconstituted and diluted in 50 mL sterile, preservative-free saline.

The BCG organisms from the vial are viable. In vitro potency is determined by an assay of live BCG organisms based on the number of colonies observed when grown on solid medium. The reconstituted product contains 10.5 ± 8.7 x 108 colony-forming units (CFU) per vial.
