Reformed user of opiates. On medicines. Tested positive for opiates. False positive caused by medicines?

My daughter is a reformed user of opiates. She went into a rehab and is now at a sober living environment.. She is on naltrexone 50mg, mirtazapine 45mg, baclofen 20mg, and synthroid 50 mcg. she is also OTC meds like Centrum, iron and stacker 3 w/o effedra. Today she went to donate blood and tested positive for opiates. Is it possible that any of the aforementioned meds could give a false positive?

Psychiatrist 's  Response

Hello and welcome to Healthcare Magic. Thanks for your query.

Usually, drug screens are specific for specific drugs and the chances of false positives are very minimal. None of of the prescription or OTC medication which she is taking is known to cause a false positive test for opiates.

So, it is unlikely that the positive drug test is due to any of these medication. I would suggest that she has a review / re-evaluation with her treating psychiatrist to check for the possibility of a relapse of her drug use.

Wish you all the best.
