Hi doctor,

My 17-year-old daughter has had psychosis for the past five weeks since she had dental surgery. She never had a psychotic episode during previous dental extractions. She is currently in a mental health facility and was on tablet Olanzapine for a few days. It was discontinued because she had an irregular heartbeat and low blood oxygen. She tested negative for drugs and alcohol during admission. She also has hypothyroidism and is taking the tablet Levothyroxine. In addition, she is currently taking the tablets Diazepam and Lorazepam. Kindly help.



Welcome to

I understand your concern. The tablet Olanzapine is one of the best antipsychotic drugs. Olanzapine does not cause low oxygen and irregular heartbeat. I suggest your daughter continue the tablet after consulting a physician, and if required the doctor might suggest another antipsychotic tablet like Risperidone (Benzisoxazole and Piperidine). I hope this helps you.

Thank you.
