Olanzapine-Induced Tardive Oculogyric Crisis Associated With Paroxysmal Psychiatric Symptoms: A Diagnostic Dilemma

We describe a rare presentation of olanzapine-induced tardive oculogyric crisis and discuss its phenomenology as well as management. Oculogyric crisis may present with stereotypic psychiatric symptoms and mistaken by clinicians for exacerbation of psychosis.

Conclusion: This case highlights the need for clinicians to be vigilant for such unusual adverse effects during antipsychotic treatment and differentiate them from relapse of primary illness.
