It's difficult to give a definite answer. It depends on how fast you metabolize the drug, how long you've been taking them, mg's, etc. I copied some information for you. When you have the drug screen, bring the prescription bottle with you and let them know you've been prescribed this medication. If not, then the following article (in my comment) may be of interest to you.

"The major route of elimination is via the kidneys where most of the drug and metabolites are excreted. Some of the drug is metabolized to phendimetrazine and phendimetrazine-N-oxide. The average half-life of elimination when studied under controlled conditions is about 3.7 hours for both the extended-release and immediate release forms. The absorption half-life of the drug from the immediate release 35 mg Phendimetrazine Tablets is appreciably more rapid than the absorption rate of the drug from the extended-release formulation"

False positives

Laboratory slip-ups are to blame for many of the mistaken test results. But even perfect labs running perfect tests will also find many false positives.

False positives are caused by:

1) Nasal decongestants such as Dristan, Neosynephren, Vicks Nasal Spray, and Sudafed, which cause false positives for amphetamines.

2)Poppy seeds like those on a dinner roll, which cause false positives for opiates. Even the highest-quality test currently available, the GCMS test, still confuses poppy seeds with heroin.

3)Pain relievers such as Advil, Nuprin, Midol, Trendar, or any medicine containing Ibuprofin cause false positives for marijuana.

4)Antibiotics such as amoxicillin or ampicillin cause false positives for cocaine.
