This is Dr. David

many medications can cause false positive for methadone in the urine

cold medications containing diphenhydramine or benadryl or doxylamine can cause false positives for methadone.

mirtazapine is a tetracyclic antidepressant, similar to a tricyclic antidepressant clomipramine which can cause false positive for methadone.

all screening tests have to be verified by a confirmatory MS/GC confirmatory test

if you are not using methadone, your confirmatory test will be negative.

I included an article which talks about medications which cause false positive results in the urine
