s is intractable, newer drugs, immuno-suppressants (such as methotrexate,
remicade,
humira, cimzia etc.) can be prescribed. I have been on methotrexate for 7 yrs, the first 5 yrs on oral tablets, but for the last 2 yrs I have weekly injections (which I do at home) of 25 mg subcutaneously.
If you want current information on Crohn's (treatments, causes etc.) I would suggest you Google Mayo Clinic and put "Crohn's" into the search box.
