I suspect it could. Other medications like it have. These drug tests are not accurate, and many prescriptions and otc meds can cause false positives, not to mention food.

Yes absolutely ranitidine can cause a false positive for meth. i recently failed a urine test. Said i used meth. Not possible! I took 1 ranitidine 150mg about two and a half hours before my drug screen. The only other drugs i took were ibuprofen and rolaids. I really dislike all medication. Thankfully my employer allowed a confirmation test. A hair test proved my innocence. Still it cost me several hundred dollars in lost wages. Personally i will choose to suffer the unbearable stomach pain rather than risk my job again.

I am going to agree... I am 7 months pregnant and I have been taking ranitidine 2-3 daily because how bad my stomach burns and my docotors office just called me telling me I tested positive for methanphetmine !!! IMPOSSIBLE! But I also found this information on another website about it making her fail for meth too!!!
