Summary
Glucocorticoids raise blood glucose and can weaken the glucose-lowering effect of metformin. With inhaled or topical budesonide the systemic effect is usually small, but oral budesonide or high doses can matter in diabetic patients.
What this interaction means in plain words
Budesonide and Metformin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Budesonide belongs to Respiratory; Metformin belongs to Endocrine.
Why it happens
Pharmacodynamic antagonism: corticosteroids increase hepatic gluconeogenesis and insulin resistance, opposing metformin's actions.
What to do
Monitor blood glucose and HbA1c when budesonide is started, stopped or changed in dose in a diabetic patient. Adjust the antidiabetic regimen if control worsens.
What to ask your pharmacist
- Is there anything I should notice while taking both?
