We report a case of tongue auto-amputation in a mentally retarded patient after a flupenthixol injection. Four days after flupenthixol administration, the patient developed orolingual dyskinetic movements involving mainly tongue biting and protrusion. Self-mutilation in this case may be secondary to flupenthixol induced acute atypical orolingual dyskinesia in the face of mental retardation.
