How Antipsychotic Medication May Save Lives
For patients suffering the chronic, debilitating symptoms of schizophrenia, antipsychotic medication is a critical component of treatment-and may literally be life-saving.
COMMENTARY
One way anti-psychiatry groups trivialize psychosis and marginalize psychiatry is by emphasizing the adverse effects of antipsychotic medications while
But even many psychiatrists may not realize that APs reduce the risk of suicide in patients with schizophrenia.
To back up a bit: an estimated
“Risk factors with a strong association with later suicide included being young, male, and with a high level of education. Illness-related risk factors were important predictors, with number of prior suicide attempts, depressive symptoms, active hallucinations and delusions, and the presence of insight all having a strong evidential basis. A family history of suicide and co-morbid substance misuse were also positively associated with later suicide. The only consistent protective factor for suicide was delivery of and adherence to effective treatment.”8 [italics added].
This last point, of course, is crucial. Indeed, the
“. . . efforts at prevention should focus on optimizing adherence to medication, and possible earlier use of clozapine, as the only antipsychotic medication with demonstrated efficacy . . . for the management of suicidality in schizophrenia.”8
Indeed, the first FDA-approved medication with an anti-suicide indication was clozapine for schizophrenia. The regulatory approval in 2003 was largely based on the International Suicide Prevention Trial (InterSePT), a randomized trial that compared clozapine with olanzapine in patients with schizophrenia and schizoaffective disorder who were at high risk for suicide.9 Suicidal behavior (measured by suicide attempts, hospitalizations, and rescue interventions) was significantly decreased in patients treated with clozapine, which is associated with a substantially lower risk of suicide than any other antipsychotic.10
There is little question that, for patients suffering the chronic, debilitating symptoms of schizophrenia, antipsychotic medication is a critical component of treatment-and may literally be life-saving.
But while clozapine provides the best evidence of anti-suicidal properties in schizophrenia, there is accumulating evidence that antipsychotic medication in general is associated with decreased risk of suicide in this population. For example,
Consistent with these data, Herings and Erkins12 studied drug refill patterns in patients believed to have schizophrenia. They found a 4-fold increased risk for attempting suicide among patients who interrupted their use of olanzapine or risperidone for at least 30 days.
Recently,
Analysis of this study by Dr. Bernard Carroll shows that for the group with no antipsychotic exposure, the suicide rate was 183 per 100,000 person years. In the medium-plus-high dosage AP groups, the combined rate fell to 129 suicides per 100,000 person years-roughly a 30% reduction from the no-medication group (B. Carroll MD, personal communication, 3/27/16). Moreover, if we make the reasonable assumption that patients receiving the highest doses of AP were probably the most severely impaired-and thus, at highest risk for suicide-these findings are all the more impressive.
Of course, in non-randomized, observational studies, there is always the potential for “selection bias” and/or “reversed causality.” For example, it is possible that patients who become suicidal-for whatever reason-stop taking their antipsychotic, rather than becoming suicidal because they stopped the medication. However, the apparent dose-response seen in the Tiihonen et al data-ie, suicide rates declined as medication dose increased-plausibly suggests that medication was actually
Multi-modal treatment
It would be incorrect to infer from this brief review that the optimal treatment of schizophrenia is simply a matter of giving patients antipsychotic medication. Persons with schizophrenia have lives beyond their symptoms. They often require and benefit from a range of adjunctive psychosocial services, including assertive community treatment, supported employment, cognitive behavioral therapy, family-based services, skills training, psychosocial interventions for alcohol and substance use disorders, and psychosocial interventions for weight management.15
But there is little question that, for patients suffering the chronic, debilitating symptoms of schizophrenia, antipsychotic medication is a critical component of treatment-and may literally be life-saving.
