Talked with a local pharmacist here in Atlanta but was told "probably not" - it is important. In fact, there were several other medications that were new to this particular client. Could any of these cause "positive" drug screen for methamphetamine. The others include: Metformin HCL - 1000 mg, Glipizide - 10 mg and lastly, Naproxen - 500 mg.
This is critical for this client's background check, etc.

Yes
I was told by my pharmacist that yes, absolutely, ranitidine (Zantac) can cause a false positive for methamphetamine. It just happened to me, this week, when my employer gave me a random UA. And, I've most certainly never used meth!
YES!!! in higher doses such as your 150mg or my 300mg. i just learned that myself after coming up positive for meth at my methadone clinic. i thought they were setting me up until i researched it. hopefully now that i can prove that, i can get back my take-home doses that i lost because of this. and hopefully this helps you. i'm googling "ranitidine false positive methamphetamine" & saving every useful page i can find. GOOD LUCK!!!
Just a word of warning. I had to do a drug test for my new job this morning. I took 3 Zantac extra strength a couple hrs before my appointment cause I had really bad heart burn. I failed my drug test. I explained to the lady what I took. The lady at the clinic said it’s a false positive for meth. Apparently there was 1 other guy the day before had the same reading. If you get random drug test at work let them no right away or you could have a very bad day.
