Get a new doctor. There is no comparision between the side effects of a topical rectal med and a systemic oral med. Common side effects of Uceris include headache, nausea, abdominal pain, fatigue, flatulence, bloating, acne, urinary tract infection, joint pain, constipation, insomnia, sleep disorders, depression, decreased blood cortisol, adrenal insufficiency, and high blood sugar (hyperglycemia, another name for diabetes).
