Drospirenone tends to retain potassium, whereas indapamide promotes potassium loss. The effects partly offset each other, so the net effect on potassium is unpredictable and usually small.
What this interaction means in plain words
Ethinyl estradiol-drospirenone and Indapamide 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
