Summary
Thiazide-type diuretics can impair glucose tolerance and raise blood glucose, which works against the glucose-lowering action of exenatide. The effect is usually modest but may loosen glycemic control in people with diabetes.
What this interaction means in plain words
Chlorthalidone and Exenatide injectable 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
Pharmacodynamic antagonism: thiazide-induced reduction in insulin sensitivity and secretion, possibly via hypokalemia, opposes incretin-mediated glucose lowering.
What to do
Monitor blood glucose and HbA1c when chlorthalidone is started, stopped or its dose changed, and adjust antidiabetic therapy if needed. Keep potassium in the normal range.
