Summary
Beta-blockers can modestly raise serum potassium by impairing cellular potassium uptake, and potassium phosphate supplements add a potassium load. The risk is greater in renal impairment or with other hyperkalemia-promoting drugs.
What this interaction means in plain words
Potassium acid and Timolol 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
Beta-2 blockade reduces cellular potassium uptake, adding to the potassium supplied by the supplement.
What to do
Check serum potassium periodically, especially in patients with renal impairment or on ACE inhibitors or potassium-sparing diuretics. Adjust supplement dose accordingly.
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?
