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.
