Abstract
This case report outlines a very rare case of glipizide‑induced severe proximal myopathy in a 61‑year‑old diabetic man. After taking 10 mg glipizide for 5 months, diabetes was well controlled but the patient presented with progressive proximal muscle weakness in all the four limbs. Clinical examination and relevant investigations suggested it to be a case of proximal myopathy and might be drug induced. De‑challenge was done and was treated resulting in reversal of the diseased state. After 3 more months, controlled re‑challenge was done and there was recurrence of proximal muscle weakness. There were no evidences of any other possible metabolic, infective, organic or other pathologic causes giving rise to that condition and Naranjo adverse drug reaction probability scale suggested that it was “probable” that glipizide was responsible for the development of myopathy in this patient.
