Hypokalemia-Induced Rhabdomyolysis From Budesonide Therapy in Crohn's Disease

We present a 71-year-old white man with active ileocolonic Crohn's disease, recently started on budesonide therapy, who presented with extreme weakness and muscle aches. He was diagnosed with hypokalemia-induced rhabdomyolysis, 3 weeks after starting budesonide therapy. His symptoms and laboratory values improved with budesonide discontinuation and appropriate fluid and electrolyte replacement. This is only the second case of hypokalemia-induced rhabdomyolysis secondary to budesonide.
