Can certain over the counter medications or prescription medications cause a false positive for Methamphetamine in a blood test?

Hi. The rantadine (zantac) will cause you to test positive for methamphetamine. My mother is also prescribed to rantadine and had a similar incident. I'm sorry this happened to you but do a little research and I hope this helped u as much as possible. God bless.

Yes it did help thanks for the reply since I made that post I did do a little research and found infact zantac does cause false positives for meth I wasn't sure the first test I failed what caused it some say red bull energy drinks can cause it too an I had a red bull the morning of my first test so the 2nd test I didn't have red bull an came back positive I knew it was 1 of the other 3 then I guess I should of not stopped after researching red bull but researched them all then I would of knew not to take any of them prior to the test but I thought red bull was my smoking gun turns out I was wrong it must have been the zantac all along iv heard dyphenhydromine that's in unisom can cause it but I'm leaning more towards the zantac iv done got a page from Wikipedia printed out about it and I will use it along with the blood test as my defense an even take a hair test if it comes down 2 it

I'm sorry this happened to you! After my*positive meth* test I went back in and talked to my Dr and had about 100 pages of people saying it was zantac/rantidine... He said your not on it... I pulled it out of my purse with his name on refilled few days before... Oh well no that cannot cause false positive... I said I want a lab request to get blood drawn. He wouldn't give it to me! So I went to walk in clinic where I got lab paper had blood drawn and what do you know NO meth and did hair test and samething it was clean! My dr is 30 min ferry ride away! Went backver with my results n showed him and the hair shows ip to 3months... I said so help me god if you pull this s*** again and don't try and help me clear my name I'm contact the media I'm gonna write to the paper! He looked at me funny.... I said without even asking me you were ready to cut me off of my meds which I cannot get out of bed with... I've got 9/3yr old kids n am single mother! I was going to use my dr test for court but cannot do so now! :( what's funny is they NEVER take credit or own their mistakes!!!

I'm drug free probation is what I need to get off my fine is just about paid I haven't did drugs or got in trouble in years idk what else to do other than what iv already done this system is a joke an needs fixing bad but I'm gonna let the hair speak volumes for me when I pass that what they gonna say next I'm David Copperfield an made the meth disappear from my hair? lol smh

To everyone wondering in may 2013 I was on a few things and got clean but method was never one of them I've been accused 3 times of this and I was insulted and angry. I have however been taking zantac aka ranitidine since I was 15 and it does indeed show as false positive in urine tests. I highly suggest prilosec aka omaprazol which is what I switched to and I've passed every urine test since then with flying colors

Thanks for the tip yea I'm researching a new alternative for heartburn that won't interfere with any test and I'll check more into prilosec its just a wonder zantac hasn't been sued over this by now or maybe they have they just been sweeping it under the rug so it won't effect there sales smh

I got a question for anybody who knows anything about a hair test how does it work? like does it go back 90days from the day the. hair was collected? or does it take a certain amount of time to get in your hair after you take a drug? the reason I ask is on the 6th I tested positive for meth and also tested positive on the 20th 4days ago I took a hair test yesterday I got my results everything came back negative so when I report to probation Monday and show them my results are they gonna say something to try and debunk my hair test the way they did my blood test and say something like it didn't have enough time to get in my hair so this doesn't prove you wasn't on meth those 2days I failed there urine test? or does my hair test prove beyond the shadow of a doubt that meth was not in my system during the time there test said I was positive? and prove that there test did in fact give me a false positive for meth both times and there is no debunking my hair test? thanks to anybody who can help answer this question for me

I take most of the medicines you mentioned and as of today am in the exact same position! my pain management doctor told me I tested positive for Meth and I absolutely DO NOT do Meth! he is sending my urine to the lab. I am freaking out as my world will crumble around me and I will not be able to move due to chronic pain, if for some reason the lab says Meth is present. I am at a total loss for words!!!

hey if you go to pain management and have a legal prescription of any narcotics then give them the complete list of everything you have took or taking even over the counter meds tell them everything an if you truly have never did meth and you know it was a false positive due too a crossover reaction drug you are taking then your test should come back fine like mine did the good news is the urine test they are gonna do is gonna be different from the one you failed they will look specifically for meth and break it down more so if meth is not there ur fine the bad news is idk what all there testing for if u have abused the drugs u was given than a special test can tell and more than likely they will cut u off ur meds and a hair test wouldn't do ya any good either only make matters worse if that's the case cuz it goes back 90days an u would be knee deep in s*** then but if u haven't abused ur meds an haven't did meth or anything illegal then a hair test is ur ticket out if the urine test comes back positive but if u are guilty then its best just too face the music not trying too scare ya just telln ya like it is hope this helps an best of luck god bless

I tried replying but my post is under review but bottom line on what I said is if you haven't abused your meds an haven't did any meth or did anything else other than what you was prescribed an the urine test comes back positive for meth and you know. for a fact its wrong then request a hair test if you are truly innocent then the hair test will be your best friend and bail you out of this situation easily but if you are guilty and you know you did something you wasn't supposed too do than the hair test can be your worst enemy an you would be far better off just dodging the hair test and just face the music head on cuz the hair test can tell them everything you have did in the last 90days an how often you did them so if your guilty u don't wanna give them that kind of insight you would more than likely get cut off from ur meds immediately but if u got nothing to hide than the hair test is the ticket an also tell them everything u have took or taking but hopefully ur urine test will come back fine an u won't have to consider a hair test not trying to scare u jus telln ya like it is hope this helps best of luck an god bless

My dr said had to have few clean before we change/up my med.. well I've had 3 clean tests... I'm single mom with no support system.. had to take extra mess yesterday in order to get up n feed NY son...oh well call someone to help you was my Dr's response.. I said look if I don't have that Lil boy I have no reason to suffer n go thru that pain.. my gramp gave me hydromorph.. to get me thru.. they tried to cause huge problems cause of that.. I said my son's only thing that matters n I have been telling you since before Xmas break that I'm not getting 4-6 hours out of my 12 hour caps... I jumped thru every hoop n done everything he's asked and have yet to get any help.. I'm spending 3-4 days week in bed only getting up to feed my boy.. now seems like each time go in he's got some excuse to not change my mess. my quality of life is fading fast... I'd rather go thru labor twice in day then deal with the pain that I do... each test has been clean since..
Any suggestions?

sorry to hear the situation your in and the only suggestion I could give ya is try too find a new doctor that might understand your situation better and I wouldn't recommend taking anything illegally for your pain no matter who it comes from because over half those law people are heartless and could careless about your situation and then if you get caught with something your not prescribed it will cost a bunch of money turn into a big deal and you will have a mark on your record and will be cut off from your meds or worse so like I said your best bet is too try an find a new doctor an explain what's going on

Over the counter zantac for heartburn aka ranitidine I know for a fact will cause you too test positive for meth and I'm sure there is more simple over the counter or prescription meds that will also cause you too test positive even though you have never touched the drug in your life an meth is the most common false positive what I would do if I was you is research everything you have taken and you should be able to figure out what's causing you too test positive that's what iv had too do I proved my innocence thru blood an hair not a trace of any drug came back the whole test was negative so that quickly debunked what they was trying to say I did zantac was my problem if ur taking that for heartburn then its more than likely ur problem too

what drugs will show a afalse reading of methodone in your urine

To be honest I'm not really sure what OTC or prescription meds that would cause a false positive for methadone if you have gotten a false positive for that specific drug then I would do a lil research on the subject an see where it leads but if I'm not mistaken I think methadone would fall under the opiate category in a urine test for instance if you was to take a Percocet or a vicodin the Percocet is oxycodon and the vicodin is hydrocodone the urine test wouldn't be able to determine which one you took all it would. know is opiates was in your system now a more advanced test like blood and hair is able to distinguish the two but if you have never taken methadone and got a false positive for it then chances are the test you took was a regular urine test if thats the case then you probably need to look more into "what causes false positives for opiates" and see if anything simple that you have eaten or taken sticks out at you there is simple things like poppy seeds off a muffin or bagel that can give you a false positive for opiates

Don't think anyone's test for methodone unless it's been in your system at some point... there's pot, amphetamines, methamphetamine, opiates, cocaine... that's the mail 5 test in drs office. some do 7/11... it depends what your doctors looking for.. and if they do it in Dr office or lab would make difference... I've been tested for like 10-15 years and never tested for methodone...
