Summary
Ephedrine can shift potassium into cells through beta-2 adrenergic stimulation, causing a small transient fall in serum potassium, which is the opposite of the effect of potassium supplementation. The net clinical effect is usually small and unpredictable.
What this interaction means in plain words
Ephedrine and Potassium citrate have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Ephedrine belongs to Cardiovascular; Potassium citrate belongs to Gastrointestinal Tract.
Why it happens
Beta-adrenergic stimulation promotes cellular potassium uptake via Na+/K+-ATPase, partly offsetting potassium supplementation.
What to do
No routine change is needed; check serum potassium if large or repeated sympathomimetic doses are given with potassium therapy.
