My Oncologist has taken me off Casodex temporarily. How long does the drug stay in my body, or how?

Casodex has a long half life of around 6 days. This means it takes 6 days to reduce the amount of drug in your body by half.

It is roughly going to take 4 to 6 weeks to clear out of your system (and longer if you have any liver problems)

You should talk with your doctor if you are experiencing bothersome side-effects.
