My 23 year old son has been in rehab twice in the past two years and was released from the last treatment center 3 months ago. His drugs of choice were hydrocodone, oxycontin, methamphetamine, and marijuana. He has started to fall into old patterns that make his wife and I concerned that he may be using again. He maintains that he is clean, and has agreed to take a 12 screen urine drug test. My question is if his prescribed medications (doxepin as a sleep aid, clonazapam for anxiety, and zoloft for depression) will show up on the screen and if so, under what categories (ie: opiates, barbituates, etc.)?
The zoloft won't show up, but the clonazepam and sleep medicine will. But he should be ok if he was prescribed those meds.
The clonazapam will probably show up as a benzodiazipine and the doxepin as a sedative. I'm not absolutely sure but this is my best guess. Good luck.
I wish people would stop posting things without prior knowledge. Clonazepam is a benzo, and will definitely show up. Any drug that ends with PAM is in a benzo class. Zoloft, otherwise known as sertraline has proven to show a false positive for benzos in researched studies. But the clonazepam would already show anyways. Doxepin is known as a hypnotic by working on H1 receptors, which is histamine. It is a tricyclic antidepressant, but is used off label for insomnia (similar to trazodone). However, since its a hypnotic and not a sedative, there should be no concerns with false positives.
"Nearly all TCAs can cause false-positive UDS results. Amitriptyline, desipramine, doxepin, and imipramine have been reported to cause false-positive results for LSD,3 and desipramine and doxepin have additionally been reported to cause false-positive results for amphetamines."
"Doses of sertraline (Zoloft) exceeding 150 mg/day could lead to false positive benzodiazepine urine drug screens."
I would have the urine screen performed at a laboratory that is aware of the prescription medications he is taking. Take the prescription bottles to the screening.
