Ranitine (Zantac) causes false positive for methamphetimines

Postby forevermommy » Wed Jul 04, 2012 7:04 am

I and my daughter both tested positive for meth even though I have not had the drug. After much research I have discovered that Ranitidine is a metabolite of Zantac and now am in the process of getting doctors and scientists to write me statements in regards to this fact to present to court to get the immediate return of my two month old daughter.

Thanks for letting us know. There are a lot of substances that cause false positives. I should compile a list.

That is not completely true. According to this study, only 19% of those who take a HUGE amount of Zantac and are tested in their first or second urination after consuming that HUGE amount will test positive for meth.

There are a lot that cause positives for all sorts of stuff. If one doesn't have a prescription, then it's hard to fight. They usually automatically re-screen a test when there are positives.

Have yet to find anything that will give a false positive for meth. The tests are so specific that they are able to rule out something else causing it - when you get into such testing as hair & nail testing. Maybe in urine testing - but if you get into the hair & nail as I said - it is extremely unlikely to have a false positive. The only medication that I have found that MAY cause a false positive is a prescription medication for Parkinson's.

Incorrect. Ranitidine is the generic name. Zantac is the brand name. They are one and the same. This drug blocks H2 receptors in the stomach to prevent the overproduction of stomach acid and is used in gastric reflux etc.

"The interference of ranitidine with the monoclonal EMIT d.a.u. amphetamine/methamphetamine immunoassay (ME) was investigated. Urine specimens collected from 23 patients receiving 150-300 mg of ranitidine daily were found to contain 7-271 mg/L of the drug when analyzed by Remedi automated high pressure liquid chromatography. Only patient specimens and urine samples with ranitidine added at concentrations greater than 91 mg/L gave false positive ME results. Of the 63 patient urine samples analyzed by ME, 12 gave false positive results. All false positive results occurred in the first or second void after ingestion. No false positive results occurred with the polyclonal EMIT d.a.u. amphetamine or TDx amphetamine/methamphetamine II assays."

Re: Ranitine (Zantac) causes false positive for methamphetim

Postby messyjessy » Fri Feb 14, 2014 9:01 am

I have contacted the company that makes zantac in order to ask them about the false positive I received from taking it and they directed me to the pharmaceutical company. WHen I contacted them I got a letter stating that I was to call them back with a case number assigned to my request for information and when I did, they confirmed that YES rantidine does in FACT cause positive for amphetamines. This will not matter however to a judge or an attorney. At least it didnt for me.
