Rare case report of moxifloxacin-induced persistent hiccups

Moxifloxacin is a broad-spectrum antimicrobial agent that is commonly used in clinical practice. Here we report an unusual case of a patient with persistent hiccups caused by moxifloxacin. A man aged in his 40s was treated with moxifloxacin for tuberculous pleurisy. Hiccups occurred 2 hours after intravenous injection of moxifloxacin and lasted into evening. On the second day after injection, hiccups occurred again and made it difficult for him to fall asleep. The clinician ruled out gastrointestinal disease, nervous system disease, electrolyte disturbance and other factors. On assessing causality of the adverse drug reaction, the Naranjo scale for moxifloxacin was six, indicating a probable relationship of hiccups with moxifloxacin. Hiccups stopped 2 min after intramuscular injection of metoclopramide. To our knowledge, this is the first case report about moxifloxacin-induced persistent hiccups. Clinicians should be aware of the rare adverse reaction.
