Summary
Dexamethasone raises blood glucose and can offset the glucose-lowering effect of glipizide. Glycemic control may deteriorate during steroid therapy, and hypoglycemia can occur when the steroid is reduced.
What this interaction means in plain words
Dexamethasone and Glipizide can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Dexamethasone belongs to Endocrine; Glipizide belongs to Endocrine.
Why it happens
Glucocorticoids increase gluconeogenesis and insulin resistance, opposing the effect of the sulfonylurea.
What to do
Monitor blood glucose regularly during dexamethasone treatment and adjust glipizide dosing as needed. Reduce doses again as the steroid is tapered to avoid hypoglycemia.
