The “dietary supplement” sold as OSR#1 is actually a toxic drug, with potentially serious side effects, the Food and Drug Administration has warned.

The product was the subject of a story published in the Times Health section a few months ago: Industrial chemical OSR#1 used as autism treatment

Here’s the latest article, on the warning letter from the agency: FDA warns maker of product used as alternative autism treatment

The story quotes Ellen Silbergeld, an environmental health expert at Johns Hopkins University, as saying: “An industrial chemical known to be toxic — his own incomplete testing indicates it is toxic. It has no record of any therapeutic aspect of it, and it is being marketed for use in children.”
