Hello friend, thanks for reaching out here for help. Trust your doctor's treatment. Glad that your sister is improving. Suitation and symptom vary patient to patients and doctors prescribe medications based this analysis. Treatment for schizophrenia
provide good results with the combination of both medications and psychotherapy
. Be positive. Instead of worrying about medication, get her to focus more on non medicine treatment plan like changes in lifestyle routines, few mindsets changes techniques or psychotherapy, excersise routines etc to further improve the recovery for long term. Feel free reach me online or Lybrate
chat for further evaluation and recommendation. Be positive. She will be alright soon.
