Metronidazole induced Reversible Cerebellar Ataxia in a patient of multiple liver abscesses: a case report

Abstract

Metronidazole is a frequently used antibiotic for the treatment of anaerobic bacterial and protozoal infections. The drug has few adverse reactions, most commonly nausea, dry mouth, vomiting, and diarrhea. Neurologic toxicity is rare and has included peripheral neuropathy, headache, dizziness, syncope, vertigo, and confusion. Cerebellar toxicity is a reported, although very unusual, manifestation of metronidazole therapy. We are reporting a case of this very rare side effect, i.e. Reversible Cerebellar toxicity, in a patient who was on prolonged metronidazole therapy for multiple liver abscesses.
