No Vicodin will not turn into or show up as hydromorphone in a drug screening, but it can show up as hydrocodone instead.

This is because Vicodin is the brand name of a product that contains hydrocodone, which is a synthetic opiate derived from codeine and thebaine. Therefore if you are on a course of Vicodin then you could test positive for opiates.

On the other hand Hydromorphone is derived from another opiate- morphine. Vicodin does not contain hydromorphone.

Vicodin turns into hydromorphone?
The reason vicodin can cause false positives is because the presence of hydrocodone, which is one of the substances tested for in a urine screening.

Here are the substances tested for in the standard ten panel screening:

  • Amphetamines (including methamphetamine).
  • Barbiturates.
  • Benzodiazepines.
  • Cannabinoids (THC).
  • Cocaine.
  • Methadone.
  • Methaqualone.
  • Opiates (codeine, morphine, heroin, oxycodone, vicodin)
  • Phencyclidine.
  • Propoxyphene.
Any prescription medication that contains a form of any of the above substances will trigger a false positive result on a drug screening.
