Summary
Corticosteroids cause insulin resistance and hyperglycemia, which can counteract the effect of pioglitazone. Systemic corticosteroid courses may require intensified antidiabetic therapy.
What this interaction means in plain words
Cortisone and Pioglitazone 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.
Why it happens
Glucocorticoids increase hepatic gluconeogenesis and insulin resistance, opposing pioglitazone's insulin-sensitizing action.
What to do
Monitor blood glucose closely during systemic cortisone therapy and increase the antidiabetic regimen if needed. Reduce doses again as the corticosteroid is tapered.
