Summary
Thiazide diuretics can impair glucose tolerance and raise blood glucose, which may reduce the glycemic control achieved with nateglinide. The effect is dose-related and usually modest at low doses.
What this interaction means in plain words
Methyclothiazide and Nateglinide 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: thiazides cause hypokalemia and reduced insulin secretion and sensitivity, raising glucose.
What to do
Check blood glucose and potassium when the thiazide is started or its dose changed. Increase the antidiabetic therapy if glycemic control worsens.
