Weeks before his death, Gabriel Myers, the 7-year-old Broward boy who hanged himself in the shower of his foster home, had been prescribed a powerful mind-altering drug linked by federal regulators to an increased risk of suicide in children.

In all, Gabriel had been prescribed four psychiatric drugs, two or three of which he was taking at the time of his death, said Jack Moss, Broward chief of the state Department of Children & Families. Moss said he is not sure which medications the boy was taking because Margate police took the foster home’s medication log as part of an investigation into Gabriel’s death last week.

Three of the psychotropic drugs carry U.S. Food and Drug Administration ”black box” label warnings for children’s safety, the strongest advisory the federal agency issues. Three of the medications are not approved for use with young children, though they are widely prescribed to youngsters ”off label” — meaning doctors can prescribe the drug even if not formally approved for that use.
