What is Bcg?
BCG (Bacillus Calmette and Guérin) is made using the organisms of a bacteria.
This medication is injected directly into the bladder, where it causes inflammation and increases certain white blood cells known as natural killer cells. These killer cells act to destroy invading cells such as tumor cells in the bladder.
BCG is used to treat bladder cancer that is localized (has not spread to other parts of the body).
BCG may also be used for other purposes not listed in this medication guide.
What is the most important information I should know about Bcg?
You should not be treated with this medication if you are allergic to BCG, or if you have tuberculosis, a fever, a bladder infection, blood in your urine, or a weak immune system (caused by certain drugs or disease such as AIDS, leukemia, or lymphoma).
You should also not receive BCG if you have had a bladder biopsy, surgery, or catheter within the past 14 days.
Before you receive BCG, tell your doctor if you are allergic to latex rubber, or if you have myasthenia gravis, a pacemaker or other artificial heart device, an artificial joint or other prosthetic, or any type of infection (including HIV).
Also tell your doctor if you have ever had tuberculosis, bypass surgery, or an aneurysm (dilated blood vessel), or if you currently need to have an organ transplant (kidney, liver, heart, etc).
Your doctor may ask you to drink extra fluids for several hours after your BCG treatment to help flush out your bladder. Follow your doctor’s instructions about the type and amount of liquids you should drink.
Call your doctor right away if you have a fever after receiving BCG, especially if the fever lasts for several hours or longer.
Antibiotics can make BCG less effective and should be avoided during your treatment with BCG. If you have an infection that must be treated with an antibiotic, you may need to stop receiving BCG for a short time. Follow your doctor’s instructions and be sure to tell any other doctor who treats you that you are receiving BCG.

Bcg Dosage
How should I take Bcg?
BCG is a freeze-dried product that is mixed with saline and other diluents (liquids) in an amount equal to approximately 8 ounces. This liquid mixture is injected directly into the bladder using a catheter inserted into the urethra (the tube for passing urine out of your bladder). You will receive this medication in a clinic or hospital setting.
This medication is usually given once every week for 6 weeks, and then given every 3 to 6 months for up to 2 years. Follow your doctor’s instructions about your specific dosing schedule.
After BCG is placed into the bladder, you will need hold the medication in your bladder as long as possible up to 2 hours. During that time you may be encouraged to lie down or stay relaxed.
For at least 6 hours after you are treated with BCG, your urine will still contain some of the medication and the bacteria it is made from. To prevent the spread of this bacteria, use a toilet rather than a urinal, and sit on the toilet while urinating.
Before you flush the toilet, disinfect the urine with household bleach in an amount that is approximately equal to how much you have urinated. Pour the bleach into the toilet in which you urinated, let it stand for 15 minutes and then flush.
Your doctor may ask you to drink extra fluids for several hours after your BCG treatment to help flush out your bladder. Follow your doctor’s instructions about the type and amount of liquids you should drink.
Call your doctor right away if you have a fever after receiving BCG, especially if the fever lasts for several hours or longer.
Being treated with BCG can cause you to have unusual results with certain medical tests. Tell any doctor who treats you that you are using BCG.
What happens if I overdose on Bcg?
Seek emergency medical attention if you think you have received too much of this medicine.
Overdose symptoms may include signs of an infection, such as fever, chills, body aches, weakness, or other flu symptoms.
What happens if I miss a dose of Bcg?
