They both show up on standard drug screens, benzos and amphetamines

And they won't be false positives. They are true positives as you are taking both those drugs. I suspect you'll have to provide prescriptions or bottles to prove you are supposed to be on those medications.

Thanks for the reponses. I plan to bring both bottles and a copy of each prescription to the test. However, that is not my question.

FYI, ritalin is not an amphetamine.

Ritalin:Amphetamine::Viagra:Nitroglycern

I have a prescriptions to take Clonazepam and Ritalin and a drug screen coming up before clinicals rotations. Two questions: First, are either of these drugs that they will be screening for? Second, could either one give me a false positive for something else, especially the Ritalin?

The Klonopin may or may not be detected; most UDS is targeted at those benzos that metabolize through oxazepam... clonazepam does not; but shares enough core structure similarity to trip an EMIT-based UDS positive.

Methylphenidate is classified as an amphetamine, as it shares a common phenylethylamine core structure as all amphetamines... it just has an MoA that's slightly different than "traditional" amphetamines.

That being said, the amphetamine assay is the sluttiest of the UDS components. Lots of OTCs can trip it positive; but Ritalin oughtn't cause the non-amphetamine assays to be positive.

PubMed search "a practical guide to urine drug screens" in the May Clinic Proceedings... this will outline the limitations of EMIT screens.

And remember, any positive UDS needs to be confirmed with GC/MS, which will definitively identify the agent in question. Bring your Rx bottles & a letter from the prescriber.

Cheers!

Does anyone know when Certiphi will contact you to schedule the drug screening? I have already completed the background check a couple weeks ago and I haven't heard anything back about the drug screening. I ask because I will be out the country for most of the summer, and am trying to take care of all the necessary requirements for the pharmacy program before I leave.

Please let me know as soon as possible! Thanks so much guys!

agree with above, either of those meds you mentioned may create positives on your uds. let them know ahead of time so positives are expected... it's better than having a positive that your school doesn't expect and then having to explain.
