Antipsychotic drugs do not have a hallucinogenic effect. The reason for hallucinations and talking nonsense after taking antipsychotic drugs may be that schizophrenia is not under control or complicated by other brain diseases. The symptoms of schizophrenia do not disappear immediately after taking the medication, but need to insist on taking the medication for a long time before it will gradually take effect. Antipsychotic drugs should be taken according to the principle of early, sufficient dosage and full course of treatment. Commonly used antipsychotic drugs include methylphenidate, aripiprazole, olanzapine and others. In general, as long as the medication is used in accordance with the doctor’s instructions, the condition will gradually stabilize and improve. The important thing is to have confidence in yourself and pay attention to your mood and daily diet and living. If the psychotic symptoms have been controlled, sudden hallucinations and nonsense, speech disorders, shouting, impulsive injury and destruction of some abnormal manifestations should be considered other brain diseases, such as organic brain diseases, hepatic encephalopathy and so on. At this time, timely consultation should be made. Antipsychotic drugs should be used under the guidance of a physician.
