Betamethasone belongs to Endocrine; Insulin degludec belongs to Endocrine.
Why it happens
Glucocorticoids increase hepatic gluconeogenesis and reduce peripheral insulin sensitivity, antagonizing insulin.
What to do
Monitor blood glucose more frequently during steroid therapy and increase insulin doses as needed. Reduce the insulin dose again as the corticosteroid is tapered to avoid hypoglycemia.
