Bed rest is required during the onset of the disease. 2. Medication: For mild to moderate abdominal pain, acetaminophen, ibuprofen and other non-steroidal anti-inflammatory drugs (NSAIDs) should be used as prescribed by the doctor. For severe abdominal pain, glucocorticoids such as dexamethasone and methylprednisolone should be used as prescribed by the doctor. If these medications are not effective, immunosuppressants such as azathioprine and cyclosporine should be added or switched.
