Budesonide
ulcerative colitis
"GI doctors diagnosed me with  IBS-D .  None of the medications prescribed produced a solution.  I was hit by repeated attacks of incontinence  (diarrhea).   
My present GI doctor diagnosed me with microscopic colitis, for which he prescribed budesonide.  It worked
 I have been using it successfully for about a year and a half.   It is an off-label drug.  not yet OK'd by the FDA for colitis. It has been ok'd for use for asthma for about 10 years but has not been ok'd for microscopic colitis.  
Therefore, I pay just under $400.00 a month for a medication that is generic placed on "Tier 4" in Medicare D.  In 2016 I was billed just under $200.00 for the same quantity .No other drugs are effective. This one is too expensive"
