Synergy
What is happening. Prednisone can promote potassium loss or potassium shifts in susceptible patients, especially at higher systemic doses, prolonged use, or when combined with other hypokalemia risks.
Mechanism. Prednisone activates mineralocorticoid receptors in the distal nephron, increasing ENaC-mediated sodium reabsorption and ROMK-mediated potassium secretion. This exchange leads to net potassium loss in the urine. Higher prednisone doses have greater mineralocorticoid activity.
Recommendation. Monitor potassium when prednisone is high dose, prolonged, or combined with diuretics, vomiting, diarrhea, or heart-rhythm risk. Increase dietary potassium only if appropriate and use supplements only if labs/prescriber guidance support it.
