    Urine testing.

    I have a two part question, I am currently taking Nortriptyline daily, and I am aware that Flexeril is a relative of Nortriptyline in the antidepressant category. Can Nortriptyline show a false positive for Cyclobenzaprine, the active ingredient in Flexeril? I tested positive for Cyclobenzaprine and did take it daily for 7 years, the test was 7 months after quitting the drug, can't possibly be showing that long can it? Thank you in advance.
