Moxifloxacin-Induced Visual Hallucinations, Alterations in Mood and Behavior, and Hyperglycemia.

ABSTRACT

Visual hallucinations are sensory perceptions that occur without external stimuli. Moxifloxacin-induced visual hallucinations are very rarely reported (<0.1%). We describe a 66-year-old woman, without any known neuropsychiatric disorder or illicit drug abuse, who experienced complex visual hallucinations, mood, and behavioral alterations secondary to peroral 1 dose of moxifloxacin treatment that persisted for approximately 36 hours. In addition, a sudden increase in her blood glucose level was noted which also improved a few days after discontinuation of moxifloxacin treatment. Although very rare, it should be kept in mind that moxifloxacin may coincidentally induce neuropsychiatric adverse effects and hyperglycemia. Clinicians should be alert to recognize such uncommon offending adverse drug reactions.
