Hi My 12 year old son has been over the top silly for the last ten days or so, about the time that we switched to a new bottle of pills. Up 'til this point his medication regimen seems to have been working very well. Usually his small dose of Adderall seems to keep the silliness in check very well. But for the last ten days it is like he hasn't taken anything. (I watch him take his pills in the morning, he is medication compliant, so I am sure that is not the issue). I am wondering, has anyone ever heard of a bad batch of pills? Seems improbable, but at this point I am ready to believe that might be possible. thanks.
