Some antipsychotic medications are ziprasidone, olanzapine, aripiprazole, risperidone and quetiapine, according to MedicineNet. These prescription medications are part of a class of drugs called atypical antipsychotics, which have fewer side effects than the drugs used to treat psychotic disorders in the 1950s to 1980s.Continue Reading
Clozapine is another atypical antipsychotic, but doctors avoid using clozapine because it can cause a serious blood disorder, notes MedicineNet. However, doctors still prescribe clozapine to patients who do not respond to other atypical antipsychotics.
Doctors use antipsychotics to treat mania, hallucinations and delusions of bipolar disorder in addition to conditions such as schizophrenia. These medications also include lurasidone and asenapine.
If a patient has severe side effects on an atypical antipsychotic medication or does not respond to it, a doctor may prescribe older, typical antipsychotic medications, according to the University of Maryland Medical Center. These medications include perphenazine, haloperidol, chlorpromazine, fluphenazine and thioridazine. These first-generation antipsychotic medications can cause nerve, muscle and coordination side effects in up to 70 percent of patients.
Some doctors prefer to prescribe first-generation antipsychotic medications because they are less expensive, notes the University of Maryland Medical Center. Atypical antipsychotic medication can cause weight gain, which can lead to heart disease and diabetes, while typical antipsychotics have a lower risk for weight gain. Atypical antipsychotics carry a lower risk of causing involuntary movements, poor coordination, and nerve and muscle side effects, but these side effects are possible.Learn more about Medications & Vitamins
