What is the most important information I should know about BCG (Theracys)?
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.
