Will taking prescription meds, such as Benedryl or Claratin......?
cause a false positive for amphetimines and barbiturits in a pediatric patient, and if so, how long will it cause it to appear in the blood when tested?

Benadryl is not a presciption med. But both Benadryl and Claratin are fat-soluable and that means they will linger in your system. They are both "downers" which means that they may show traces of Barbituates, but not "uppers"- Amphetamines. Those are easily explained. Millions of people take those medications. Your pediatric patient has hopefully had some professional do the prescribing. If you are giving a child Benadryl, they had better be seriously allergic to something. You would be better off removing that "something".
Benadryl and claratin are both fine... Ephedrine or pseudoephedrine might cause problems though (I'm not 100% sure on that)
They should allow a retest if you've got a good excuse for the false positive.
Drug testing is immoral.
neither benedryl or claritin are prescription drugs, and neither of them are amphetimine or barbiturate, so, no, they would not cause a false positive.
they are antihistamines, and those stay in the blood stream for approximately 48 hours.
