Welcome to Bladder Cancer Canada, the site that no one wants to belong to. I’m sorry to learn of your Dad’s situation. This is a tough one. I have done BCG treatments but haven’t taken Enbrel. Lots of drugs interact with BCG. Hopefully you will hear from someone soon.
I have to ask – was there any discussion with your Dad’s doctor about another similar drug that could be taken temporarily as a substitute for the short time that he would be undergoing BCG? Hopefully the substitute wouldn’t interact. Failing that, is it safe for your Dad to stop taking Enbrel for a short period of time?
Just trying to think outside the box….Maybe call the Bladder Cancer Canada toll free number and ask if you can connect with Jack Moon and BCC’s Medical Advisory Board. Just maybe they may know of something. (((((HUGS)))))
