Managing Lactose Intolerance in Patients Taking Prednisone

Introduction to Prednisone Therapy

The American Society of Clinical Oncology notes that prednisone can cause gastrointestinal symptoms including nausea, abdominal discomfort, and altered bowel habits, independent of lactose content 1, 2

When bowel edema is present, the European Society for Medical Oncology recommends administering intravenous methylprednisolone rather than oral prednisone, as bowel edema significantly impairs gastrointestinal absorption of oral medications 3
The American Gastroenterological Association suggests providing gastric protection with proton pump inhibitors when prednisone is used for more than 4 weeks 2

For patients with inflammatory bowel disease requiring prednisone, the European Society for Clinical Nutrition and Metabolism prioritizes IV methylprednisolone 60 mg every 24 hours or IV hydrocortisone 100 mg four times daily, rather than oral prednisone, to bypass concerns about both lactose content and impaired absorption 3
The same society recommends providing IV fluid and electrolyte replacement, including at least 60 mmol/day of potassium supplementation, for these patients 3
