Educational Pearls:

• Zyprexa (olanzapine) is a second generation antipsychotic with multiple other uses
• Excellent for treating nausea in patients undergoing chemotherapy or with THC hyperemesis syndrome
• Helps with the psychological and emotional aspect of pain
• Effective in treatment of headaches
• Can be given under the tongue
• Fewer incidences of dystonic reactions compared with first generation antipsychotics
• Patients using anti-dopaminergic should not receive antipsychotics because they also work on dopaminergic receptors
