ABSTRACT Carbonic anhydrase inhibitors can cause nephrolithiasis. We studied 20 patients receiving long-term carbonic anhydrase inhibitor treatment for periodic paralysis and myotonia. Three patients on acetazolamide (15%) developed renal calculi. Extracorporeal lithotripsy successfully removed a renal calculus in one patient and surgery removed a staghorn calculus in another, permitting continued treatment. Renal function remained normal in all patients. Nephrolithiasis is a complication of acetazolamide but does not preclude its use.
