Would Lomotil cause a false positve in drug screening for herion?

Believe it or not, anti-biotics can cause false/positives on drug tests, there are many drugs out there that are prescribed that can cause a person to fail a drug test... If you are taking a specific medication for a certain illness etc, I would let the screener know up front so that they can be aware of anything that may effect the reading of the results. By law they can not hold it against you if you are on a prescribed medication... Blaze22 good luck

Blaze is right! Lomotil contains a drug called atropine (drying agent) so better safe than sorry!

I have Crohn's Disease and I take high dose Lomotil.(8 per day) for diarrhea, as well as loperamide. I took a urinalysis drug test for employment. I received a call and was told my drug screening tested positive for Demerol.

I have NEVER taken Demerol or even heard the name before the test. I was told it is a very power pain reliever and is really only used in hospital setting. Also, that Demerol had fell out of favor for other pain medication.

I don't know if the false positive came from Lomotil, another medication or a combination of the medication I consume. Either way I couldn't explain the "Demerol" in my urine and my job offer was withdrawn. So far all I can find online about this issue is from people like myself who've had false positive and not much from the medical/ scientific community.

I was upset and embarrassed from this accusation and lost my job. I hope the scientific community finds out what causes these false positive, so no one else has to suffer the same fate.
