There are quite a list of them. Search for “failed drug screen for amphetamines” and you will find compiled lists everywhere. The previous answer is totally incorrect. I failed one for taking Mucinex, a cold med, over the counter! They tested further and I was proven right!

EMSAM, Selegiline (sp) will. Especially if you start wearing it 24 hours and previously wore it for only partial days, which since it's burned through so fast, will look even worse.

So can Zantac + Phenergan, along with Mucinex.

Rantanadine which is generic Zantac. Just happened to my husband so his sample had to b sent to a lab and he has to wait another week to go to work!! He's never done drugs in his life!!

Benzedrex can, I just recieved a false positive. They will hopefully catch the mistake in the lab.

Propylhexedrine is the drug name, I think.

Did the lab clear it up

It is 100% without a doubt your Adderal. Methamphetamines is the same thing as Amphetamines.

Okay, m2matRN, I gotta call ya on this one. They are not the same thing! That"s like saying Xanax and Valium are the same thing. Huge difference. Same family, yes, they are both in the benzodiazapine family, but completely different. For example, you are part of a family, but probably very different from your brother or sister, right? As of date, there are hundreds of OTC drugs like Afrin, Vicks Formula 44 , Prozac, Prilosec, Zantac, etc. I could go on and on.

Theraflu cold and sinus will cause falsely for amphetime

I am new, so please be kind. I am a lab tech and performed drug testing for several years. This was before I was ran over by a truck, crushing my back and pelvis. Since my injuries, my opinion has changed drastically about pain meds. I am ashamed to admit I believed everyone that came to the ER, with back pain just wanted drugs. Now I understand how much a back injury can hurt. There is no way to describe it accurately enough.

No "medication" causes methamphetamine to show up on a drug screen.

Well I just read several articles that several things will cause a false positive. Such as, I had a bad cold and used alot of nasal spray with phenylephrine and tested pos. for methamphetamine but not amphetamine. First of all, my body is extremely pure from all drugs and will always be that way. I have never even been tempted. But to test positive for methamphetamine and know in your deepest heart true to god and the worshiping of my body I am puzzled about my results. I believe with how much I studied this once I got my test it can be true. I just don't know why amphetamine came up negative. I thought that Meth would fall under that catagory. If you find new info, can you please help me with the truth. I live in a very small town, didn't even have a clean catch ua and they still went by those results, yet they declined when I asked them to test my blood. Now why would that be, especially when I have a very neg. relationship with the (male) nurse who took my sample. PLS HELP even though your answer was against what I'm telling you. GOD BLESS!

I'm trying to answer using my cell phone. When I get my PC back from the repair shop, I will post some articles I have bookmarked on this very subject. It basically states that so many different factors can cause false positives. In one study, 30% of test subjects showed positive for amphetamine when no drugs were present at all. I believe you when you said it should not have been positive. I will definately post the articles for you when I get my pc back. I am sorry for assuming the worst. chris

I went to my doctor today and tested positive for methadone and I have never in my life even SEEN meth. This is the SECOND time I tested positive for drugs when I do not use them. The first time I tested positive I was so upset I cried. My doctor sent a sample to Birmingham Alabama and had it retested with another kind of of test and it came back negative. How many people have lost jobs over this kind of test? How many people have lost their children over a false drug test? How many people have went to jail because of a false drug test? Please know that if someone tells you they do not use drugs but test positive anyway, keep in mind not every test is right, and if your a doctor, keep in mind that every test is not gospel, and every patient who does test positive and tells you the test is WRONG, just MAYBE they are telling the truth as I am living proof that all tests are not right, and people do deserve another test.Does anyone else think something should be done about improving these so called "accurate testing methods"?

Chris that was big of u..cause i for 1 havebeen testung positive & im not using and im a god fearing woman.its humilating & im really trying to figure outn why god is taking me through this & letting me suffer.

Ally39 10 Nov 2011

ChristineATU I hope you still look at this page I am hoping you still have those articles about the false positive. I have been trying different diets and drinks but nothing that i need a prescription for so why did my test come back positive for amphetamine? if anyone knows why please help of course the doctor said if it is there i took it. that is not true

marksgrahamjr 8 Aug 2013

That's not true. Desoxyn, a adhd medication, will test positive for methamphetamine.

Fred2113 15 Jan 2018

When you have a false positive, you demand that they send it to the lab and confirm it. They are legally obligated to do so if you request it. The lab doesn't make mistakes. If it's false they'll tell you it's false. I did this with my state probation officer. I'm on felony probation so I would've gone to jail for a positive but I told them it had to be a false positive and I wanted to send it off. I was vindicated.

CatherineAC 3 April 2018

You are absolutely INCORRECT! Maybe you should do some research before giving others your opinion instead of actual facts

Ericplc 23 Jan 2019

Desoxyn shows positive for methamphetamines.

Nbjefferson 25 Feb 2019

Yes, I would like answer on how I tested positive and I don’t do drugs. I’m need help

Mbowman168 1 Nov 2019

No. You are incorrect. Adderall and other like medications and over the counter medications can show up on the dip or initial lab screen. The labs do an immunoassy test that picks up emzymes/proteins. Amphetamine and methamphetamine like mda/meme are classed or grouped together. ONLY on a confirmation test will the lab separate the class of drugs to show the true drug. Some states require confirmation. Many, many more do not.

shiftace816 1 March 2023

I just have to point out that is incorrect. Phenylephrine is a stereo isomer of methamphetamines. Meaning that they contain the exact same molecules and the same number too. They are just reversed.. free discount card
