The number of children taking powerful antipsychotic drugs has nearly tripled over the last 10 to 15 years, according to recent research. The increase comes not because of an epidemic of schizophrenia or other forms of serious mental illness in children, but because doctors are increasingly prescribing the drugs to treat behavior problems, a use not approved by the Food and Drug Administration (FDA). And a disproportionate number of those prescriptions are written for poor and minority children, some as young as age 2.

Doctors are prescribing antipsychotics even though there’s minimal evidence that the drugs help kids for approved uses, much less the unapproved ones, such as behavioral problems. And to make matters worse, the little research there is suggests the drugs can cause troubling side effects, including weight gain, high cholesterol, and an increased risk of type-2 diabetes.
