How is neutropenia related to schizophrenia? Clozapine is a second generation antipsychotic often administered when other antipsychotics are not affective. However, neutropenia is a potential side effect of clozapine use. Neutropenia can result in death and involves low levels of neutrophils; the white blood cells that help the body fight infection. What is the evidence for neutropenia? Moderate quality evidence suggests the incidence of mild neutropenia in people taking clozapine is around 3.8%, and the incidence of severe neutropenia is around 0.9%. Death from neutropenia is rare at around 0.013%. October 2020


What is polypharmacy? Medication combination treatment, also called polypharmacy, has been utilised in clinical practice for patients who are unresponsive or partially responsive to antipsychotic monotherapies. What is the evidence for polypharmacy? Moderate to high quality evidence finds a medium-sized improvement in overall symptoms, and a small improvement in clinical response, with antipsychotic polypharmacy vs. monotherapy. There is also less study discontinuation for any reason with antipsychotic polypharmacy. However, studies assessing rates of relapse after switching from polypharmacy to monotherapies found no differences in relapse rates and more study discontinuation with polypharmacy. Moderate quality evidence finds antipsychotic polypharmacy is most…


What is clozapine? Second generation antipsychotics (sometimes referred to as ‘atypical’ antipsychotics) such as clozapine are a newer class of antipsychotic medication than first generation ‘typical’ antipsychotics. Second generation antipsychotics are effective for the positive symptoms of schizophrenia. It is sometimes claimed that they are more effective than first generation antipsychotics in treating the negative symptoms of schizophrenia, although the evidence for this is weak. Negative symptoms include a lack of ordinary mental activities such as emotional expression, social engagement, thinking and motivation, whereas positive symptoms include the experiences of perceptual abnormalities (hallucinations) and fixed, false, irrational beliefs (delusions).
