Summary

Naproxen can reduce renal potassium excretion and may cause hyperkalemia, especially in patients with impaired kidney function. Combined with potassium citrate, the risk of significant potassium elevation is increased.

What this interaction means in plain words

Naproxen 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.

Naproxen belongs to Musculoskeletal; Potassium citrate belongs to Gastrointestinal Tract.

Evidence level: Moderate

Why it happens

NSAID inhibition of prostaglandin synthesis lowers renin-aldosterone activity and renal perfusion, decreasing potassium excretion.

What to do

Monitor serum potassium and renal function at the start and during therapy, particularly in older patients or those with CKD. Reduce the potassium dose or discontinue the NSAID if hyperkalemia occurs.

What to ask your pharmacist
