Celecoxib and Potassium, a caution.
Celecoxib can still affect kidney prostaglandins and potassium balance despite its COX-2 selectivity. Potassium supplements increase the potassium load and can contribute to hyperkalemia when renal excretion is reduced. The combination is most risky with kidney disease, dehydration, diabetes, older age, ACE inhibitors, ARBs, or potassium-sparing diuretics.

Caution
What is happening. Celecoxib can still affect kidney prostaglandins and potassium balance despite its COX-2 selectivity. Potassium supplements increase the potassium load and can contribute to hyperkalemia when renal excretion is reduced. The combination is most risky with kidney disease, dehydration, diabetes, older age, ACE inhibitors, ARBs, or potassium-sparing diuretics.
Mechanism. COX-2 inhibition in the kidney can reduce prostaglandin-mediated renin release and alter aldosterone-dependent potassium excretion. Supplemental potassium can then accumulate when renal reserve is limited.
Recommendation. Do not add potassium supplements to celecoxib without a reason and a monitoring plan. Check serum potassium and kidney function if you need both, and avoid celecoxib during dehydration unless your clinician advises otherwise.
