What to do when a 12 year old girl is under medication for autism but her hallucinations are not under control?

Hello doctor,

My daughter is 12 years old, and she always showed a great deal of anxiety started having a lot of school refusal during 5th grade, so we took her to see a psychiatrist who ultimately diagnosed her with high functioning autism and started her on a Lexapro. School refusal continued, but we managed the school year. When she started 6th grade, she admitted to her school psychologist that she had been hearing voices for about a year. The voices were a group of teens about her age, and they were all very negative.

We sought treatment again with another doctor who put her on Risperidone, which failed to control the voices, so she was switched to Seroquel, which also failed after a month. We had a move to another state, so we had to change doctors. The move did not go well with our doctor, and she ended up with a suicide attempt and four acute hospital stays and one long term stay.

Her hallucinations are now fully engulfing her days, and they are tactile, visual, olfactory, and audio. She also admitted to an early suicide attempt while she was 10. Her new doctor has tried Abilify, Latuda, high dose Seroquel, and high dose Zyprexa. All have failed. She had also tried depression medications like Trintellix, Wellbutrin, Lexapro, Cymbalta, and Zoloft. Nothing has worked for more than two months.

Her current doctor is not willing to try another medication and is telling her to live with her hallucinations. My daughter is 13 and has very little quality of life. In our place, there are minimal resources here, even being well insured and willing to pay out of pocket. I am looking for advice on what to do next. Do I travel out of state, do I visit another type of doctor?

It is also important to say that she has been diagnosed with schizophrenia. My husband nor I have any family history of schizophrenia going back about five generations, although I do have mental illness frequently on mine (depression and bipolar). I had a completely healthy pregnancy, and she was born on her due date without complications. She was big at 8lbs 9ounce and 21inches.
