Class: Biologic response modifier
- Powder for suspension, lyophilized 1 to 8 × 10 8 colony-forming units
- Powder for suspension, lyophilized 10.5 ± 8.7 × 10 8 colony-forming units
Bacille Calmette-Guérin (BCG) is a lyophilized preparation of an attenuated, live culture preparation of the BCG strain of Mycobacterium bovis used in carcinoma in situ of the urinary bladder and as prophylaxis of primary or recurrent stage Ta or T1 papillary tumors following TUR. Precise mechanism of action is unknown.
Indications and Usage
Treatment and prophylaxis of carcinoma in situ of the urinary bladder; prophylaxis of primary or recurrent stage Ta and/or T1 papillary tumors following transurethral resection TUR.
Local control of accessible tumor.
Immunosuppressed patients or persons with congenital or acquired immune deficiencies; patients with current symptoms or a previous history of systemic BCG reaction; persons with active tuberculosis; postpone treatment until resolution of a concurrent febrile illness, UTI, or gross hematuria; allow 14 days to elapse following biopsy, TUR, or traumatic catheterization.
Dosage and AdministrationCarcinoma In-Situ of the Urinary Bladder
Adults ( TheraCys )
Intravesical Each dose is administered intravesically via catheter once a wk for 6 wk followed by maintenance therapy consisting of 1 dose given at 3, 6, 12, 18, and 24 mo after initial treatment.Adults ( Tice BCG )
Intravesical Each dose is administered intravesically via catheter once a wk for 6 wk. This schedule may be repeated once if tumor remission is not achieved and if deemed clinically necessary; thereafter, administer 1 dose at approximately monthly intervals for at least 6 to 12 mo.
- The suspension is instilled into the bladder slowly by gravity flow, via the catheter. Do not force the flow.
- Reconstitute and dilute immediately prior to use. If there is a delay between reconstitution and administration, it must not exceed 2 h.
- Do not inject subcutaneously or IV.
- Patients should be instructed to increase fluid intake in order to flush the bladder following BCG treatment.
- Individuals mixing the agent should wear gloves and eye protection and avoid contact of BCG with broken skin.
- BCG should not be handled by persons with an immunological deficiency.
- After use of the product, place packaging and all equipment and materials used for installation in a container for biohazardous materials and disposed of according to local requirements.
- BCG should be retained in the bladder for 2 h before voiding.
- Disinfect urine voided during the 6 h period following installation with an equal volume of 5% hypochlorite solution (undiluted household bleach) and allow to stand for 15 min before flushing.
- Tice : Patients should not drink fluids for 4 h before treatment and should empty the bladder prior to BCG administration.
Keep BCG and any accompanying diluent refrigerated between 35° and 46°F. Use immediately after reconstitution and discard after 2 h. Do not expose the freeze-dried or reconstituted BCG to sunlight, direct or indirect. Keep exposure to artificial light to a minimum. Do not use any reconstituted product that exhibits flocculation or clumping that cannot be dispersed with gentle shaking. Do not use after expiration date printed on label.
Drug InteractionsAntimicrobial therapy
Antimicrobial therapy for other infections may interfere with the effectiveness of BCG therapy.Bone marrow depressants/immunosuppressants/radiation
May impair immune response to BCG.
Laboratory Test Interactions
May result in tuberculin skin reactivity.
Cardiac (unclassified), coagulopathy (less than 5%).
Malaise (40%); fatigue (7%); neurologic unclassified, pyuria (1%); dizziness, headache (less than 5%).
Skin rash (less than 5%).

Because BCG live contains live, attenuated mycobacteria, there is a risk of transmission. BCG infections have been reported in health care workers, primarily from exposures resulting from accidental needle sticks or skin lacerations during preparation of BCG for administration. Nosocomial infections have been reported in immunosuppressed patients receiving parenteral drugs that were prepared in areas in which BCG was prepared. BCG is capable of dissemination when administered intravesically. Death has occurred.
Monitor for the presence of symptoms and signs of toxicity after each treatment. Determine the tuberculin reactivity of patients by purified protein derivative testing before treatment is initiated.
Category C .
Safety and efficacy not established.
No overall difference in safety or efficacy was observed between older and younger patients.
Systemic adverse reactions (eg, malaise, fever, chills) of 1 to 2 days' duration may represent hypersensitivity reactions and can be treated with antihistamines.
Fever of 103°F or more, or acute localized inflammation persisting longer than 2 or 3 days suggest active infections and evaluation for serious infectious complications should be considered.
The acute, localized irritative toxicities of BCG may be accompanied by systemic manifestations consistent with flu-like syndrome.
Risk of occurrence may be increased in patients with small bladder capacity.
Immune deficiency syndromes
Administer with caution to persons at high risk for HIV infection. Do not vaccinate children with a family history of immune deficiency disease.
Infection of aneurysms and prosthetic devices
BCG infection of aneurysms and prosthetic devices (eg, arterial grafts, artificial joints, cardiac devices) have been reported following intravesical administration of BCG.
The vial stopper for TheraCys contains natural rubber latex that may cause allergic reactions.
Do not give intravesical BCG any sooner than 1 to 2 wk following TUR, biopsy, traumatic catheterization, or gross hematuria.
Do not use in the presence of a UTI because administration may increase the risk of disseminated BCG infection or increase the severity of bladder irritation.
Overdosage (eg, active local or systemic BCG infection) occurs if more than 1 amp/vial is given per instillation.
- Check with health care provider as soon as possible if there is an increase in existing symptoms, if symptoms persist even after receiving a number of treatments, or if any of the following symptoms develop: blood in urine, chills, cough, fever, flu-like symptoms, frequent urge to urinate, increased frequency of urination, increased tiredness/fatigue, joint pain, painful urination, skin rash.
- Notify health care provider immediately if a cough develops.
- Void in a seated position to avoid splashing of urine.
- Disinfect urine voided for 6 h after instillation with an equal volume of 5% sodium hypochlorite solution (undiluted household bleach); allow to disinfect for 15 min before flushing.
- Increase fluid intake to flush the bladder in the hours following BCG treatment. Patients may experience burning with the first void after treatment.
