crohn's disease, maintenance
"My husband has only been taking Pentasa for a few days, but he has had terrible side effects since day one.  His Crohn's had become progressively worse over the years so his GI doctor prescribed Pentasa. He has chest pains, headaches, severe nausea and vomiting as well as loss of appetite.  I saw that one person had to lower his dose after 3 weeks, and I wonder if that was due to his experience of these effects also.  I know Pentasa has great potential, but how long will these effects last?"
