Antipsychotics may increase the risk of death in young people, research finds

Young adults and children who are recommended high-dose antipsychotic medicines are at high risk of unexpected death. Although other medications to treat their conditions are available. The study was conducted at Vanderbilt University Medical Center and published in JAMA Psychiatry.

Youth having age between 5 to 24 years beginning antipsychotic treatment when received prescriptions higher than 50 mg chlorpromazine equivalents had a 3.5-fold increased risk for sudden death.

“Antipsychotics have possibly life-threatening metabolic, cardiovascular, and other adverse effects, though, in kids and adolescents, these effects are often related with an overdose of medication, and lethal consequences are rare,” Wayne A. Ray, Ph.D., from Vanderbilt University School of Medicine, and colleagues wrote.

“However, there is less information from controlled researches of the association of antipsychotics with death in younger people.”

In this survey, Ray and colleagues compared the unexpected death risk among youth and children who started therapy with antipsychotic vs. control prescriptions.

They used the records from Medicaid enrollees aged 5 to 24 years in Tennessee. These participants had no diagnosis of a severe somatic disorder, psychoses, Tourette syndrome or chronic tic disorder.

Participants were separated into three groups;

  • A higher-dose group (those receiving dosages higher than 50 mg chlorpromazine equivalents)
  • Lower-dose group (participants receiving dosages 50 mg or lesser chlorpromazine equivalents)
  • A control group (those getting ADHD medication, mood stabilizers or antidepressants)

What the study found?

The scientists measured deaths during 1-year while out of a hospital or within 7 days post-hospital admission. Secondary results involved unexpected deaths not because of overdose and death as a result of cardiovascular or metabolic causes.

There were 189,361 members in the control group, 30,120 in the higher-dose group and 28,377 in the lower-dose group.

Children and adolescents in the higher-dose group had an 80% increased threat for death. It was attributable to a more than three times larger risk for unexpected deaths (adjusted HR = 3.51; 95% CI, 1.54-7.96), according to the outcomes.

The unadjusted occurrence of demise in the higher-dose group was 146.2 per 100,000 person-years. This was significantly more than that in the control group rate of 54.5 per 100,000 population.

The researchers reported no increase in the risk for death due to suicide or injuries. The risk remained high for unexpected deaths not because of overdose (HR = 3.5; 95% CI, 1.35-9.11). And death rate associated with cardiovascular and metabolic causes (HR = 4.29; 95% CI, 1.33-13.89). The research showed no considerably increased risk related to antipsychotic doses of 50 mg or lower.

“The study discoveries appear to strengthen existing strategies for improving the consequences of antipsychotic treatment in children and youths,” Ray and associates wrote.

These strategies include;

  • restricting to indications for which there is a good indication of efficiency
  • a suitable trial of alternatives comprising psychosocial interventions when probable,
  • cardiometabolic valuation before therapy and monitoring after therapy
  • limiting treatment to the lowest dose and shortest extent possible.

Due to the commonness of some syndromes for which antipsychotics are suggested off-label, like for ADHD, and the number of medicines for directed, and off-label use is increasing, concerns about sudden deaths are also likely to grow, Barbara Geller wrote in a comment. He is an MD, from the department of psychiatry, Washington University in St Louis.

“These outcomes heighten the already increased attention about recommending antipsychotics to adolescents and children and emphasize to consider situational triggers of psychopathology to avoid medicating the environment,” Geller wrote.
