No, Bactrim, an antibiotic, will not give a false positive reading for Benzos.

Yes it does. It caused a false positive for me. So i went to my probation officer and Took a lab test which came out negative for Benzos but positive for Bactrim. So In theory It obviously causes a false negative for Benzo for standardized Drug Tests.

I am so glad I found this answer. I have to take random urine test for my pain management and I have been on Bactrim DS for 2 weeks now and have 2 more weeks to go and my drug test showed today that I was positive for Benzo's. I have never taken any type of Benzo's. So, now I am calling my family dr. and have her do a drug screen and not a standardized Drug test. I was so upset that I was being falsely accused of taking meds. that I don't even know or have.

The same thing happened to me last week I took a drug test for my parole officer and it came up positive for benzos and I know that I haven't taken any. I've been trying to find out why for the last week and worrying cause I thought I was gonna go back to jail for something I didn't do. I've been taking Bactrim DS for the last 2 weeks now I'm gonna contact him and ask if bactrim was found in my lab results.

Yes Yes Yes I just spent 3 weeks in jail for taking bactrim. I know it was the bactrim because I haven't taken anything else. So please if you have to drug test DO NOT take bactrim.

I just took a drug test today for my po and it was a dip test. I am taking Bactrim for a UTI and my urine test came back for benzos not once but twice. My po is sending it to the lab. I have not used anything but bactrim so yes it can cause a false positive.
