Summary

What this interaction means in plain words
Indapamide and Potassium acid 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

What to do
Monitor serum potassium and renal function periodically and adjust supplement dose to maintain normal levels.
