Azathioprine advice?

[viajera]

Hi all! I'm new to this site, and also immunosuppressants. My doctor just prescribed Azathioprine for active Crohn's, and as I am planning to return to Spain (from the US) for another school year, and won't be in the US with my regular doctor, it makes me kind of nervous.

Also, I'm trying to figure out how much these medications will cost (also Uceris and Fosamax), since my insurance there doesn't cover prescriptions.

I'm particularly concerned about catching every bug that comes along, since I was already doing that last year when I wasn't on this medication. And I've read about lymphoma and other cancers...!

Any advice would be greatly appreciated!
