title: Intractable Acute Pain Related to Fluoroquinolone-Induced Peripheral Neuropathy.
abstract: Fluoroquinolones are widely prescribed antibiotics, used for various infectious etiologies. These antibiotics carry the possibility of the serious adverse effect of peripheral neuropathy, with a true incidence not known owing to its rare existence. Recently, the Food and Drug Administration (FDA) has required alterations to drug labels to highlight this adverse effect of fluoroquinolones. This is a case report of a single patient at an inpatient neurology service at an urban academic medical center in the United States. The patient is a 20-year-old male, with well-controlled type 1 diabetes mellitus, presenting with a short duration of bilateral lower extremity pain following a 10-day course of levofloxacin for suspected epididymitis. The patient was initially diagnosed with complex regional pain syndrome and treated with a variety of pain medications, including lidocaine infusions, hydromorphone, methadone, and ketamine infusions. After review of the patient's history and limited response to medical management, the patient's condition was reclassified as an adverse effect from fluoroquinolone treatment. Pain of unknown etiology can be perplexing, both for the physician and the patient. Reporting of similar incidents attributed to medication adverse effects will increase the awareness of this type of neuropathy, avoid future cases of misdiagnosis, and enable early detection and treatment.
