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&#039;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?"
