Use of B‐complex vitamins and olfactory training for treating COVID‐19–related anosmia

Abstract

Abstract A 42‐year‐old male patient was diagnosed with coronavirus disease 2019. His symptoms improved 2 weeks after lopinavir therapy (800 mg/day). However, he was subsequently diagnosed with complete anosmia. Magnetic resonance brain imaging showed no abnormalities. We prescribed B‐complex vitamins and olfactory training. Forty days later, he recovered.
