Summary
Olanzapine can cause hyperglycemia, insulin resistance and weight gain, which oppose the glucose-lowering effect of exenatide. Glycemic control may be worse than expected in patients treated with both.
What this interaction means in plain words
Exenatide injectable and Olanzapine 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
Pharmacodynamic antagonism, as olanzapine worsens glucose metabolism while exenatide lowers glucose.
What to do
Monitor blood glucose and HbA1c regularly and adjust antidiabetic therapy as needed. Consider a lower metabolic-risk antipsychotic if control is poor.
