This is just crazy, the same thing just happened to me two days ago. I go to pain management for chronic back and neck pain. Fentanyl 50mg and oxycodone 5mg. Been taking both for about 9 years. And It's the same for me, I have never even seen methamphetamine let alone tried it. But my last urine test came back positive for methamphetamine. How?!? There is no way because I can’t stand the people on it where I live and never have I physically seen it. So how is this possible? I never knew sudafed was in methamphetamine until today. And I took sudafed two days before my test. My doctor never asked if I might have taken something like that or anything. He just accused me of doing methamphetamine. So now I guess I go back in ten days for a meeting. Idk why, I really don’t want to be accused of something I don’t do but with the problems with fentanyl these days I’ll never get it back anywhere else. So I’m going to have to go back. It’s like they're the big drug dealers now. And we gotta do what they say.

I recently went for a drug screen and tested positive for methamphetamine. I don't use that drug. I'm 25 weeks preggo and I have been taking meds for my cold (dimatapp Vick inhaler). I'm also on high blood pressure pills as well as tylenol with codeine. How is it possible?

How long would you have to take the OTC drugs to test positive to show up on a blood test. Thanks

I was told that there is no test for "Methamphetamine". The only test available is an Amphetamine test. So, if someone tests positive for amphetamines does that mean it is positive for Methamphetamine? This person was taking Phentermine and not following the prescription guidelines; she finished a 30 count bottle in about 2 weeks. Would that affect the results?

Being that she is on Phentermine, yes she can get a false positive for meth. Phentermine is a type of Amphetamine.

I do urine drug screens all day and I hear everything from "someone must have put meth in my milk", to "someone spiked my cigarette". Yeah no! A screening has the potential to give you a false positive for just about anything, however; once confirmation testing has been ordered the process used breaks the drug down to the smallest molecule, basically the finger print to the molecule. Labs are pretty darn sophisticated. Nowadays they have the ability to distinguish Sudafed from Methamphetamines. Wellbutrin, like so many claim, is why methamphetamines is in their urine drug screen is just the criminal mind working over time. Sorry, but if the lab detects meth after confirmation has been done, you did meth!

It's very hard to take methamphetamine and lie about it due to the fact if used for a long period of time their features are the telltale sign. Such things as having a sunken in face, tooth rot, weight loss, are just a few. Before I would accuse someone of lying I would take a look at some of the physical changes that cannot be hidden before I made any opinion. I myself use to take methamphetamine once a week with a friend, it was kind of a ritual I guess. But I have been clean for over a year and just took a hair follicle test and tested positive for methamphetamine?? I take Wellbutrin, Proventil Asthma inhaler, along with the inhaler that has a steroid in it, Ibuprofen, Adderall, and Metoprolol for high blood pressure. Anyone of these on the research I'm doing can test positive for methamphetamine. Well, I'm not sure of the Metoprolol, but being a high blood pressure medication which is one thing I've heard that can cause a false positive. The testing Agency can do one of two types of testing for methamphetamine. It's sad but just for monetary reasons alone, these agencies ruin peoples lives just to gain a larger profit margin. if the lab chooses to do the cheaper of the two from which is what happened to me while I had to submit to a 12 panel hair follicle test. They rarely use the one that can go deeper and determine the medications that you take that may be causing a test to show up as methamphetamine? I was just taking my last test out of 4 separate tests 90 days apart so I could have my kids on the days our divorce decree says.. And there was no way in hell I would chance doing methamphetamine on my last test that I had to pay $400.00 dollars for each test. Then, sure enough, it showed positive for methamphetamine. I haven't even seen methamphetamine in over a year. Now I'm back at square one having to do the 4 tests all over again. Sounds like they know how to make money because the court specifically states I have to go to a certain testing agency.

The amitriptyline almost killed me. I was falling all over the place losing my balance and everything!!! Literally falling on my face in the middle of the night. I was scared but was hoping it would get better and that maybe the effects were just too strong at first but nope it got much worse. That stuff is HORRIBLE and I wouldn't recommend it to ANYONE!

Zantac does show up as Methamphetamine on a drug test, I work at a Family practice and we do regular drug screens on patients, and Zantac shows up on the drug screen. Just let the lab know all meds you take.

Well you should believe him, because I'm on probation and just 5 days ago my probation officer drug tested me with a urine drug screen & I am 8 and a half months pregnant and the only medicine I take is Tums for my my heartburn, and I dropped dirty for both methamphetamine and amphetamines. Tums is the only medicine I have taken during my pregnancy; so yes I should believe him because I'm also a living proof that Tums will show up positive for both!

aspirin, omeprazole, vicks inhaler, zantac 150mg. The rantidine causes it; i failed for methamphetamine and i have most certainly not used methamphetamine... I also take benzadrex and trazodone will do it as well... That's bs too cause im in a custody battle. I wouldn't risk that for nothing. My dr.'s office said i failed for methamphetamine. I'm on adderall and i made them send it back for further testing! I'm even gonna offer a hair follicle test! Good luck to you. I hope this helps!
