Summary
Drospirenone has antimineralocorticoid activity and can raise serum potassium. Beta-blockers can modestly increase potassium by impairing cellular uptake, so hyperkalemia is possible in predisposed patients such as those with renal impairment.
What this interaction means in plain words
Betaxolol and Drospirenone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Betaxolol belongs to Cardiovascular; Drospirenone belongs to Endocrine.
Why it happens
Additive potassium-raising effects: drospirenone antagonises aldosterone and beta-blockade reduces cellular potassium uptake.
What to do
Usually no action is needed in healthy patients. Check serum potassium in those with renal impairment or other potassium-raising drugs.
What to ask your pharmacist
- Is there anything I should notice while taking both?
