Customer Question
Hello. I am taking...

Hello. I am taking a drug screening for work tomorrow. I took a zantac 150 on Thursday night. Should I be concerned about a false positive?

Doctor's Assistant: Is this a time sensitive issue? What type of specimen are they testing?

It is a urine specimen

Doctor's Assistant: Anything else in your medical history you think the doctor should know?

I don't think so. I only take OTC meds PRN. Only other prescribed Rx is birth control.

Doctor: Dr.Anil, Doctor replied 7 months ago

I understand your concern.

Well as you describe, The half-life of ranitidine (Zantac) is about 3 hours, so half of it is out of your system in 3 hours, leaving half and it gets completely get rid off from your system between 18-24 hours.

Zantac can indeed cause false positive screening tests for amphetamines in routine drug urine test. If the test was confirmed with GC/MS however, this false positive would be eliminated.

Chances of passing your urine drug test are very high as you'll undergo a test on Monday and most likely your Zantac would be eliminated from the system by Saturday.

Let me know if you have any further query so we can discuss it thoroughly in every aspect.
