Can You Get a False Positive Drug Test from Medications?

You go to the doctor for an ailment and he prescribes you a medication. You follow the directions carefully, are regimented to take your medication on time, and never miss a dose. Then your employer performs a random drug test for everyone in the office. Despite not using or abusing drugs, the results say that you’ve failed your drug test.

What happened?

You might be surprised to learn that false positive drug tests due to medication are becoming more common. A 2010 report shows the following medications have been known to cause false positive drug tests:

  • Brompheniramine
  • Bupropion
  • Chlorpromazine
  • Clomipramine
  • Dextromethorphan
  • Diphenhydramine
  • Doxylamine
  • Ibuprofen
  • Naproxen
  • Promethazine
  • Quetiapine
  • Quinolones (ofloxacin and gatifloxacin)
  • Ranitidine
  • Sertraline
  • Thioridazine
  • Trazodone
  • Venlafaxine
  • Verapamil

In 2018, another study discovered false positives from mexiletine, a drug given for the treatment of arrhythmia. As research probes deeper, more and more common medications are being attributed to so many false positive drug test results.
