If you were taking <span title="hydrocodone,xanax,phenergan">hydrocodone,xanax,phenerg...</span> and sinus tablets,can test show falsepositive for hydromorphone

Question

I had a test show positive for hydromorphone,but I had not taken this drug what could cause this if not the prescriptions i was taking?

Answer 1

Why not? When you are taking that many different drugs anything could be possible, especially since hydrocodone and hydromorphone are both opioids

Answer 2

a test would be positive for &quot;opiates&quot; both hydrocodone (basically vicoden/lortab) and hydromorphone (dilaudid) are opiates. xanax would be positive for benzos.
