Summary
Thiazide diuretics can impair glucose tolerance and may partly offset the glucose-lowering effect of exenatide. Glycemic control may worsen after thiazide initiation or dose increase.
What this interaction means in plain words
Exenatide injectable and Hydrochlorothiazide have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Thiazide-induced reduction in insulin sensitivity and secretion (partly via hypokalemia) antagonizes incretin-mediated glucose lowering.
What to do
Monitor blood glucose and HbA1c when starting, stopping or changing the thiazide dose, and adjust antidiabetic therapy if needed.
