12 per cent of all Canadian prescriptions of anti-psychotics were for children aged 8 or under, including three-year-olds.

Antipsychotics are being widely prescribed to children with behaviour and mood problems, with a significant proportion going to children under nine, new research shows.

Ninety-four per cent of 176 child psychiatrists in Canada surveyed are prescribing powerful drugs known as atypical antipsychotics for a variety of disorders and symptoms, including anxiety, attention-deficit hyperactivity disorder and "poor frustration tolerance."

While most prescriptions were for children 13 and older, a "surprising" number were for the very young: 12 per cent of all prescriptions were for children aged eight or under, including three-year-olds.

None of the drugs has been officially approved for use in children.

Risperidone (brand name Respirdal) was the most commonly prescribed atypical antipsychotic to children, followed by olanzapine (Zyprexa) and quetiapine (Seroquel).

All are in a different class from Ritalin, a stimulant used to treat attention deficit disorder in children.

Originally developed to treat schizophrenia and mania, so-called ATAs are now increasingly being used to treat non-psychotic disorders in adults, children and teens.

"These medications are currently being used off-label without clear guidelines for indications, dosing and monitoring," researchers report in the most recent issue of the Canadian Journal of Psychiatry.

"There is an urgent need for more data regarding safety and monitoring of these medications in children."

In the U.S., the number of visits to a doctor that ended with a patient under 20 being prescribed an anti-psychotic soared six-fold between 1993 and 2002.

The new Canadian survey can't answer just how many children or teens in Canada are on antipsychotics. But it shows prescribing by child psychiatrists and pediatricians who specialize in developmental problems is "ubiquitous."

"The trouble with a study like this is, it doesn't tell us whether that's a good thing or a bad thing. We just know it's happening," says lead author Dr. Tamison Doey, head of the division of child and adolescent psychiatry for the city of Windsor and an adjunct professor at the University of Western Ontario.

"Intuitively we all say, 'Geez, these are young kids to be on medicine."
