Summary
Diclofenac may impair renal potassium elimination, and with potassium citrate this can lead to hyperkalemia. Risk is higher in older patients and those with reduced kidney function.
What this interaction means in plain words
Diclofenac and Potassium citrate 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.
Diclofenac belongs to Musculoskeletal; Potassium citrate belongs to Gastrointestinal Tract.
Why it happens
Inhibition of renal prostaglandin synthesis lowers renin and aldosterone and reduces potassium excretion, adding to the supplemental potassium load.
What to do
Check serum potassium and creatinine at baseline and after starting the combination. Lower the potassium dose or stop the NSAID if potassium rises.
