Your doctor or a health care provider will administer this medicine. When used to protect against TB, it is injected into the skin. Keep the vaccination area dry for 24 hours after receiving the vaccine, and keep the area clean until you cannot tell the vaccination area from the skin around it.
When used for bladder cancer, the medicine flows into your bladder through a tube or catheter. Avoid drinking fluids for 4 hours before your treatment. You should empty your bladder before treatment. During the first hour after the medication is infused, you will lie on your stomach, back, and sides for 15 minutes each. Then you will stand, but you should keep the medication in your bladder for another hour. If you cannot keep the medication in your bladder for the entire 2 hours, tell your health care provider. At the end of 2 hours you will empty your bladder in a seated manner for safety reasons. Your urine should be disinfected for 6 hours after the medication is administered. Pour a similar amount of undiluted bleach in the toilet after you urinate. Let it stand for 15 minutes before flushing.
Various dosing schedules may be used. Your doctor will schedule your treatment. Ask your doctor to explain any directions you do not understand.
When the vaccine is given to protect against TB, it usually is given only one time but may be repeated if there is not a good response in 2-3 months. Response is measured by a TB skin test.
