Summary
Beta-blockers such as atenolol can slightly reduce cellular potassium uptake, and potassium phosphate supplements add a potassium load. Hyperkalemia is uncommon in patients with normal renal function but is more likely with renal impairment.
What this interaction means in plain words
Atenolol 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
Impaired beta-2 mediated cellular potassium uptake combined with added exogenous potassium.
What to do
Check serum potassium and renal function periodically, particularly in patients with kidney disease or taking other potassium-raising drugs.
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?
