Hydromorphone Hydrochloride Showing Up on Drug Tests
Hydromorphone hydrochloride (Dilaudid) is an opioid that comes in both short-acting and long-acting formulations. The short-acting form of the drug starts to work within 30 minutes, reaching its peak effect within an hour. In contrast, the long-acting form starts to work within six hours and reaches peak effectiveness within nine hours.
However, even after its pain-relieving properties start to wear off, the drug may still show up on drug tests, including urine, blood, saliva and hair tests.

Half-Life of Hydromorphone Hydrochloride
The half-life of a medication is the time it takes for your body to break down half of the drug. Generally, it takes five half-lives for a drug to completely leave your system.
- The half-life of short-acting hydromorphone is 2–3 hours, meaning it can stay in your system for up to 15 hours.
- The half-life of long-acting hydromorphone is 8–15 hours, meaning it can remain in your system for just over three days.

Hydromorphone Hydrochloride Prescription Facts
Hydromorphone is a semi-synthetic opioid analgesic, meaning that it is partially man-made. The drug is prescribed to change the way your body feels and reacts to pain. It is prescribed for severe pain that can only be controlled with opioids.
As with any other prescription drug, hydromorphone hydrochloride carries a risk of side effects. These side effects can include:
- Dry mouth
As with other opioids, overdose is possible and potentially deadly. This is especially true if you take the drug with other central nervous system depressants, like alcohol or benzodiazepines.
Inform your doctor if you are experiencing any side effects from hydromorphone hydrochloride and avoid any medications or substances it interacts with, including alcohol, while it remains in your system. If you’re unsure about the safety of taking other medications or drinking alcohol after taking your prescription of hydromorphone hydrochloride, talk to your doctor.
Hydromorphone Hydrochloride Regulations
The U.S. Drug Enforcement Administration (DEA) has listed hydromorphone as a Schedule II controlled substance, meaning it has a high potential for abuse, dependence and addiction.
Most Commonly Abused Drugs Containing Hydromorphone Hydrochloride

How Hydromorphone Hydrochloride Affects the Brain and Body
Hydromorphone hydrochloride works in your brain to change the way your body feels pain. It works by binding to the brain’s mu-opioid receptors, reducing pain sensations.
Over time, your body can become physically dependent on hydromorphone. Physical dependence is not the same thing as addiction. Instead, it means that your body has come to expect the presence of hydromorphone. Therefore, if you abruptly stop taking hydromorphone, this may bring about uncomfortable withdrawal symptoms. Consult your doctor to receive assistance as needed while weaning off of this prescription.
Opioid addiction can happen to anyone, even if they’re used as prescribed. If you or a loved one is struggling with an addiction to hydromorphone or another opioid, addiction rehab treatment addresses the physical and psychological impacts of opioids to help you learn why you became addicted in the first place.
