Wiil Ranitidine Produce A False Positive For Methamphetimines In Hair Follicle Test And Where Is The Proof? (Page 6) (Top voted first)

While I was pregnant I was prescribed to take ranitidine for heartburn. After my child was born I took a urine test that came up negative. Cps sent these sample off and said I tested positive for meth. I submitted to a hair test on my child and a nail test on myself. The results were positive for meth. The Metabolites were very low in both of us but the amphetimine levels were high, but I had ephedrine during the c section. Will ranitidine cause a false positive in a hair test and where is the documented proof? They have taken my newborn away from me its five days now without touching or seeing her. I am desperate to get my baby back. If a doctor responds please be willing to submit documentation in writing. Thank you to anyone with the answer.

Hey, your links were useless. One does not even exist, the other wants you to register and jump through hoops and still i cant find the research you mention.

How did this all work out? I ended up testing positive AGAIN from a dr urine test about 9 yrs after it happened at a job. That made me do more research and realize it was the Zantac bc I am prescribed 800mg/daily for my stomach, FROM THAT VERY DOCTOR! I'm working on an editorial to submit to the New York Times, and other national sites.

Although, I somewhat agree, my gcms test came back positive also. But I take around 1000mg of Zantac daily after having gastric bypass surgery and have for a decade, so maybe it was built up in my system bc others were cleared after gcms testing. I did hair follicle to clear my name and it happened twice, around a decade ago also and Oct 2016.

I feel I need to clarify some facts regarding the Ranitidine (Zantac) causing false positives. Recently I've dealt with a situation where I had to warn my employer about possible urinalysis false positive for amphetamines because I took Zantac coincidentally for the first time a couple days before my drug screen. YOU WILL most likely experience a false positive for amphetamines, not just methamphetamines but all other amphetamines if you take 100mg or more of Zantac 2 to 3 days before your drug screen WHEN an instant drug screen is utilized. For example, the little urine cups with the test strip built in, or when the provider of the test uses a dip stick or other same day or instant test methods. KEEP IN MIND, IF your urine will be sent to an offsite professional drug screening lab, 95% of the time the urine will actually be processed through a thorough laser or light refraction test inside an automatic machine that is pre-calibrated to test for a very long list of controlled or semi controller substances. When urine is tested using this lab method, you will not receive a false positive because you ingested Zantac. The test is very detailed and specific for each individual substance it tests for so a false positive is extremely unlikely. ALTHOUGH, I have heard many stories of these labs cutting corners and just using simple cheap dip sticks for the urine if the lab knows the test is simply a screen for employment to check for heroin, methamphetamine, cocaine, thc, etc...

If your employer or whoever does not purchase the high-end results test printout then there's a chance your urine will not get the high tech thorough test and you may end up with a false positive. There's also a few other substances like poppy seeds, because if you happen to eat poppy seeds from a place that gets organic unwashed seeds, the opiate level on the seeds can vary greatly throughout a bag of seeds... Also certain anti-diarrhea OTC medicine can give you a false positive for opiates. Hope this helps everybody! Remember, once you fail a drug test for a new job, is very hard to get a retest for many large corporations for safety and fraud issues and that first impression is hard to forget.. It'll always be in the back of your boss's head that you might really be on drugs. Also for court, often they just accept the first test result and trust the lab, making it very hard to talk them into giving a continuance and retest. The court wants you to fail usually.. They want you to plead guilty and pay the fine or end up losing your kid so the state gets to sell your kid via adoption and they get a lot of money for spitting out kids. Ever wonder why it seems CPS or family services are so eager to take your child and come up with any reason as an excuse to put your child in a foster home and adopt it out? Its all about money.

When the test is conducted in a lab using a laser or light retracting process, the machine is calibrated extremely precisely to give a reading on 20 to 30 various controlled substances or medicines. In that case a false positive for amphetamines via ingredients in Zantac should not happen unless there's a serious issue with the machine testing the urine. The only definite way to get a false positive from Zantac within the 2-4 day window is by using an instant urinalysis test kit or dip stick test. Those are designed to change color in a few different places from a chemical reaction due to certain drug substances being present in the urine.. Same concept as a pH test strip. It's very simple and not very reliable or precise. It's good enough for a quick test to hire a new employee, to make sure in the spot, they aren't a drug user but as I've said in so many ways above, you really shouldn't have anything to worry about if your urine is being sent to a blood and or urinalysis laboratory. That is unless they decide to be cheap and cut corners and test your urine with a simple test strip (which they've been known to do) if the customer doesn't order a detailed report on what's in the urine. Only a cheap and very unprofessional lab would do such things for customers who pay premium prices to have the urine sent and tested.. Good day

Re: mrs call (# 10)

I take drug tests for my doctor and almost always fail for methamphetamine from taking zantac. They always give me a mouth swab and I pass... so maybe ask for that. I hope this helps you.

Re: childless in tn (# 2)

I've been taking Zantac 150 for months and was recently trying to get a job, but I failed a drug test. They said I was on the this drug and I've never even seen it in my life. I don't mess with drugs of any kind. Not only did I fail this drug test, it goes on my work records. It's time for us as Americans to step up and do something about this Zantac 150 or 175 if you ask me for my opinion.

Our experts in this field need to be humble enough to recognize that technology will continue to advance, and an open mind could mean literally the difference between a child being thrown into the system. These are people's lives we are talking about. Going through that was one of the most traumatic experiences of my life.
