This preparation is not to be used as a vaccine against tuberculosis.

SII-ONCO-BCG (BCG LIVE USP) for intravesical instillation is a live lyophilized preparation derived from attenuated strain of Mycobacterium bovis (Bacillus Calmette Guerin).

Each vial contains :

Bacillus Calmette-Guerin strain : 40mg/ml
Between 1-19.2 x 108 Colony Forming Units (CFU)

For treatment of flat Urothelial Cell Carcinoma in Situ of urinary bladder and as adjunctive therapy following Transurethral resection of primary or relapsing superficial noninvasive papillary tumors that are limited to the bladder mucosa (stage Ta or T1).
Intravesical BCG Immunotherapy has been shown to reduce tumor recurrence and prevent progression.

Treatment should be started 2-3 weeks after performing TURBT. The treatment schedule is weekly repeated instillation with SII-ONCO-BCG (120 mg) during first 6 weeks, followed by 3 consecutive weekly instillations at 3 months, at 6 months and thereafter every 6 months upto 36 months. This means that a patient who stays tumor free after the initial resection will receive a total of 27 instillations in a period of three years.
The duration and frequency of maintenance treatment should be evaluated on the basis of tumor classification and clinical diagnosis.

Add 1 ml of a sterile isotonic preservative free saline (0.9 % NaCl) by means of a sterile syringe to the contents of 1 vial of SII-ONCO-BCG and allow stand for a few minutes. Then gently swirl the vial until a homogenous suspension is obtained (Caution: avoid forceful agitation). The above procedure may be repeated to reconstitute each subsequent vial/s used.

Transfer the reconstituted suspension from the vial/s into a 50 ml syringe. Rinse the empty vial/s with 1 ml each of sterile isotonic saline. Add the rinse fluid to the reconstituted suspension in the 50 ml syringe.
The above procedure may be repeated for each subsequent vial/s used.
Finally dilute the contents of the 50 ml syringe (by adding sterile physiological saline solution) up to a total volume of 50 ml. Mix the suspension carefully. The suspension is now ready for use.

Insert a catheter by aseptic technique through urethra into bladder and drain completely. Attach 50 ml syringe containing the prepared solution to the catheter and instill into bladder slowly by gravity where it should be retained for 2 hours. Patient should not ingest any fluid 4 hours before and 2 hours after instillation and should lie on their stomach for first 15 mins after instillation. Patient may have frequent position changes on either sides every 15 mins in order to distribute the medication properly throughout the bladder. Thereafter, the patient should be made to void the instilled contents in sitting position. If there is any bleeding or any other signs of traumatic injury, treatment should be postponed for at least 1 week.

Adverse effects are generally mild and transient. They appear to be directly related to cumulated CFU count of BCG administered in various instillations. Common side effects are:

  • Frequency, urgency of micturition and dysuria- these symptoms usually occur from 2nd or 3rd instillation onwards.

  • Cystitis and typical granulomatous inflammatory reactions which occur in the mucosa of urinary bladder may be an essential component of anti-tumour activity of the drug. The symptoms usually disappear within 2 days and do not require treatment. Cystitis may be more prolonged during maintenance treatment and if severe, Isoniazid 300 mg daily can be given with analgesics until symptoms disappear.

  • Malaise and low-medium grade fever and/ or a flu like syndrome. These symptoms usually occur after 4 hours of instillation and disappear within 24-48 hours.


  • Fever more than 39C. The fever resolves within 24-48 hours with antipyretics and fluids.

  • Systemic BCG infections due to traumatic catheterization, perforation of bladder or early BCG instillation after extensive TUR which may be manifested by pneumonitis, hepatitis or cytopenia. Patients with such symptoms should be treated with tuberculostatic drugs as per treatment schedules used. Triple drug therapy with or without Cycloserine for some weeks should be used.

  • Granulomatous Prostatitis.

  • Arthritis, Arthralgia, Haematuria, Orchitis, Transient urethral obstruction, Epididymitis or bladder contraction may occur.

SII-ONCO-BCG for intravesical instillation carcinoma in situ of bladder should not be used in:

  • Impaired immune response irrespective of whether this impairment is congenital or caused by disease, drugs or other therapy.

  • Positive HIV serology.

  • Pregnancy and lactation; safety of the mode of therapy in pregnant women, nursing mothers and children has not been evaluated.

  • Positive tuberculin reaction in conjunction with clinical evidence of existing active tuberculosis.

  • Urinary tract infections: treatment should be withheld till urine culture is negative and antibiotic therapy is stopped.

  • Trauma to urinary bladder.

  • A patient with fever needs careful evaluation before therapy is instituted.

  • On going treatment with antitubercular treatment.

SII-ONCO-BCG should not be administered intravenously, subcutaneously or intramuscularly.
The product is not intended for immunization.
The preparation contains live attenuated mycobacterium (BCG) and should be used with aseptic technique. All equipment, supplies and receptacles in contact with BCG should be handled and disposed off as biohazardous. Urine voided for 6 hours after instillation also needs to be properly disinfected.


  • Do not expose the contents to light before and after reconstitution. Use the vaccine immediately after reconstitution and discard unused portion.

  • Reconstitution, preparation and administration should be performed under aseptic conditions.

  • Before the first instillation Tuberculin test should be performed, in case positive, the drug is contraindicated only if there is an evidence of active tuberculosis infection.

  • Delay treatment in-patients who experience traumatic catheterization till mucosal damage has healed.

  • Adequate HIV assays are recommended in-patients who are at risk of HIV infection.

  • It is recommended to refrain from sexual intercourse for one week after instillation or use a condom.

SII-ONCO-BCG is sensitive to most antibiotics specially to anti-tubercular drugs like Streptomycin, Isoniazid, Ethambutol, Rifampicin and PAS (Para-amino Salicylic Acid). It is not known whether interactions occur during intra-vesical instillation of SII-ONCO-BCG or whether the interactions result in clinically relevant reduction of multiplication activity of SII-ONCO-BCG. Hence, it is not clear whether activity of SII-ONCO-BCG is influenced by concomitant therapy with antibiotics. If a patient is receiving antibiotics treatment then intra-vesical instillation should be postponed till completion of antibiotics treatment (also see the "Contraindications"). Studies on interaction with other drugs are not performed.

SII-ONCO-BCG should be stored in dark at +2 AND +8C. Do not expose the contents to light before and after reconstitution. Use immediately after reconstitution. Discard unused portion.

Do not exceed the expiry date stated on the external packing.
