Interactions
Olanzapine may antagonise the effects of levodopa and dopamine agonists. Drugs that induce CYP1A2 or glucuronyl transferase enzymes e.g. omeprazole and rifampicin, may increase olanzapine clearance. Inhibitors of CYP1A2 may potentially inhibit olanzapine elimination. Carbamazepine may increase the clearance of olanzapine. Concomitant admin of activated charcoal reduced the oral bioavailability of olanzapine by 50-60%. Caution should be taken when olanzapine is administered with centrally acting drugs and alcohol.
