Customer Question

I have an 84 year old pt that tested postive for meth and hasn't been exposed to any drugs. She failed twice with a urine test at the hospital. We are now dealing with adult protective services. Can any of her medication make her test positive like met for min and rantidine?

This is Dr. David

there are many medications which can cause false positives for methamphetamines.

I included an article which talks about this.

antihistamines and over the counter cold medications which contain Brompheniramine and Phenlpropanolamine and nasal inhaler decongestants can cause false meth positive urine tests

antidepressants such as Bupropion and Trazodone have been shown to be able to cause false positives

antipsychotic medications such as Chlorpromazine and Promethazine for nausea can cause false meth positive tests

Ranitidine for stomach acid can cause false positives.

with any urine positive result, they have to be confirmed by MS/GC confirmatory tests.

if she is taking ranitidine, her MS/GC confirmatory test will be negative for methamphetamines

Take a look at the article I included
