Do you have any of the pills left? You could get the leftovers tested. But I would ask your pediatrician. I would guess you probably don't need to be specifically concerned.
Yeah, I replied to another commenter, but I have some of the syrup left over and I'm sending it to be tested. Turns out the folks who discovered this have publicly-available testing. I'm thinking that the limited duration is a good thing. Fingers crossed.
