Summary
Heparin can reduce aldosterone production, and potassium citrate supplies additional potassium. Together they may raise serum potassium, which is most relevant in patients with renal impairment, diabetes or other hyperkalemia risks.
What this interaction means in plain words
Heparin and Potassium citrate / citric acid can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Heparin suppresses adrenal aldosterone synthesis, reducing renal potassium excretion, while potassium citrate adds a potassium load.
What to do
Monitor serum potassium and renal function, especially with prolonged heparin therapy or at-risk patients. Reduce or stop the potassium supplement if potassium rises.
