Do I need to worry if my 3 yr old soon to b 4 in aug, 38lbs.....could have possibly taken 9 pills of synthroid 88. Called poison control and they said not to worry that he will b very hyperactive and moody for nxt 4 days. But my wife is still concerned even though we were told it will b ok after it works out of his system. What symptoms should we look for for the worst case scenario? Not sure if he took that many or not....that s the impression we are getting sence he threw away one of the packages and we can t find it now. That was earlier this morning not sure exactly what time.....but Definately over 9 hrs ago.
