How does this medication work? What will it do for me?
Bacillus Calmette-Guérin (BCG) belongs to the group of cancer-fighting medications known as antineoplastics. BCG is thought to treat cancer in the bladder by stimulating the body’s own defense system to attack the cancer cells.
Your doctor may have suggested this medication for conditions other than the ones listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
What form(s) does this medication come in?
Each vial of freeze-dried preparation contains 1 to 8×108 CFU of TICE BCG which is equivalent to approximately 50 mg wet weight.
How should I use this medication?
BCG is always administered under direct supervision of a doctor. It is added to a solution that is instilled into the bladder through a catheter (tube). Before the fluid is instilled into your bladder, you will be asked to empty your bladder completely. The solution containing BCG should be held in your bladder for 2 hours.
When an instillation of BCG is finished, you should be sitting down to empty your bladder. To prevent bladder problems, you will need to drink extra fluids for several hours after each treatment so that more urine is passed. Make sure to empty your bladder as frequently as possible.
Because BCG is a live bacteria, it can cause infection. It is therefore important to disinfect any urine passed in the first 6 hours after treatment with 2 cups of undiluted household bleach. Allow the urine to sit with the bleach for 15 minutes in the toilet before flushing it.
This procedure is usually repeated once a week for 6 weeks, with additional instillations occurring at the 8th and 12th week, and then once a month for a year.
Many things can affect the dose and schedule of medication that a person needs, such as body weight, other medical conditions, and other medications. Your doctor may decide on a schedule different than the one listed here.
It is important to use this medication exactly as prescribed by your doctor.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

- have an active tuberculosis infection
- have current active infection

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Handling of urine: Because BCG contains live mycobacteria, your urine may also contain the live bacteria. You should use appropriate infection control procedures to protect others from infection. This is especially true if you are living with someone who has reduced immunity (e.g., on chemotherapy).
For up to 6 hours after therapy, you should urinate while sitting to minimize the risk of splashing urine. Also, you should disinfect with 2 cups of household bleach for 15 minutes before flushing.
Systemic BCG reaction: Although rare, a systemic granulomatous illness have been reported subsequent to exposure to BCG. Let your doctor know immediately if you develop a fever. Although rare, the reaction is much more likely to occur if BCG is administered within 14 days of biopsy, TUR, or traumatic bladder catheterization (associated with hematuria).
Pregnancy: BCG has not been studied for use by pregnant people. Tell your doctor immediately if you become pregnant during treatment. BCG should be used during pregnancy only if the benefits outweigh the risks.
Breast-feeding: It is not known whether BCG passes into breast milk. You should not breast-feed while receiving BCG treatment due to risk of potential harm to the infant.
What other drugs could interact with this medication?
There may be an interaction between bacillus Calmette-Guérin and any of the following:
- antibiotics (e.g., amoxicillin, azithromycin, ciprofloxacin)
- iodinated contrast agents
- medications that suppress the immune system:
- corticosteroids (e.g., dexamethasone, hydrocortisone, prednisone)
- medications used to treat conditions such as cancer, inflammatory bowel disease, multiple sclerosis, psoriasis, rheumatoid arthritis, or medications used after a transplant
If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:
- stop taking one of the medications,
- change one of the medications to another,
- change how you are taking one or both of the medications, or
- leave everything as is.
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
