Olanzapine (Zyprexa) and dental care
Olanzapine has strong anticholinergic effects that significantly reduce saliva flow. The combination of substantial weight gain (common with olanzapine), metabolic syndrome, and dry mouth raises both cavity risk and the practical difficulty of dental work (impressions, prosthetic fit). Tardive dyskinesia from long-term use can also affect jaw and tongue movements.
Never start, stop, or change a medication based on what you read here. Bring questions to your dentist, physician, pharmacist, or prescribing clinician.
