What Can Causes False Positive Result For Amphetamines On A Urinalysis?

I just received a false positive for Amphetamines on a urinalysis. I do not take any prescription medications. In the past week I have taken Aleve, Benedryl, and some DayQuill about a week ago. Will any of these medications or any specific foods cause a false positive for Amphetamines?
