Summary
Drospirenone has antimineralocorticoid activity and can raise serum potassium. Beta-blockers such as carvedilol can modestly reduce cellular potassium uptake, so hyperkalemia risk may be slightly increased, mainly in patients with renal impairment or other potassium-raising drugs.
What this interaction means in plain words
Carvedilol 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.
Carvedilol belongs to Cardiovascular; Drospirenone belongs to Endocrine.
Why it happens
Additive potassium retention from drospirenone and impaired beta-adrenergic cellular potassium uptake from carvedilol.
What to do
Check serum potassium in at-risk patients, such as those with renal impairment or on ACE inhibitors, during the first cycle of drospirenone.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
