Dilaudid is the brand name for hydromorphone, a powerful prescription opioid used to treat severe and chronic pain. It is chemically similar to morphine but significantly more potent, and like other opioids it carries a high potential for misuse, dependence, and addiction, which is why it is classified as a Schedule II controlled substance by the DEA and why medical professionals routinely monitor its use through drug testing.

Dilaudid can be detected through several types of drug screens, each with a different detection window. Urine testing is the most common method and can identify Dilaudid use for up to four days after the last dose, while blood tests have the shortest window at around 24 hours. Saliva tests can detect use within minutes and up to 48 hours after ingestion, and hair follicle tests have the longest detection window, identifying use for up to 90 days.

What Is Dilaudid?

Dilaudid is a common brand name for the drug hydromorphone. This comes in the form of a tablet or oral solution. The extended-release formulation of hydromorphone is Exalgo.

Chemically, hydromorphone is similar to opioid analgesics like:

  • morphine
  • oxycodone
  • hydrocodone
  • codeine
  • oxymorphone
  • the synthetic opioid fentanyl

Hydromorphone is a central nervous system depressant that binds to the body’s opioid receptors and can provide pain relief. This makes it an effective pain medication to treat severe pain and chronic pain.

Why Do People Get Screened For Dilaudid Use?

Dilaudid is classified by the U.S. Drug Enforcement Administration (DEA) as a schedule II controlled substance. This means it has a high potential for abuse and addiction.

This is, in part, due to the addictive nature of some of its side effects.

Short-term side effects of Dilaudid can include:

  • dry mouth
  • happiness
  • relaxation
  • constipation
  • lightheadedness
  • drowsiness
  • slow breathing

Doctors may test patients for opioid use as a preventative strategy in order to prevent opioid abuse and addiction.

Urine Tests For Dilaudid Use

Urine screenings are the most common type of testing method. Urine tests can detect Dilaudid use for up to four days after your last dose.

Blood Tests For Dilaudid Use

Blood samples have the shortest detection window. Dilaudid remains in the blood for up to 24 hours, or one day after use.

Saliva Tests For Dilaudid Use

Oral fluid tests, such as saliva tests, can detect drug use the fastest. Saliva tests can detect Dilaudid use in as little as a few minutes and for up to two days after ingestion.

Hair Tests For Dilaudid Use

Through an analysis of hair follicles pulled from the head or body, hair tests can detect Dilaudid use for up to 90 days after last use.

Factors That Can Affect How Long Dilaudid Stays In Your System

Not everybody processes drugs the same way. The amount of time it takes for Dilaudid to leave the body can depend on a wide range of personal and genetic factors.

Factors that can affect Dilaudid detection times include:

  • frequency of use
  • amount of drug used
  • polydrug abuse (taking multiple drugs)
  • metabolic rate
  • overall health status
  • older age

Taking higher doses of Dilaudid over time, or developing physical dependence, can extend the average detection window. This is because you’re likely taking more than the average person. This can also increase the risk of developing an addiction to Dilaudid. Without treatment, Dilaudid addiction can develop into a life-threatening drug problem.

How To Get Dilaudid Out Of Your System

Stopping Dilaudid is the only way to get it out of your system. For some people, however, this isn’t as simple as it sounds. Becoming physically dependent on or addicted to Dilaudid can make it very difficult to stop taking it. This can trigger uncomfortable withdrawal symptoms, such as diarrhea and vomiting.

If you’re addicted to Dilaudid, the safest way to stop using it is to seek professional help through a drug detox program.

Find Treatment For Dilaudid Addiction

If you or a loved one has been abusing Dilaudid, getting it out of your system through detox is only the first step towards recovery. Most people with substance abuse or addiction need the additional support and structure that can be found within a drug rehab program.

Treatment programs for Dilaudid addiction may include:

  • inpatient rehab programs
  • counseling
  • group therapy
  • family therapy
  • dual diagnosis treatment
  • Narcotics Anonymous (NA) groups
  • medication-assisted treatment (e.g. methadone maintenance, buprenorphine)
  • outpatient rehab programs

Recovering from opioid addiction is possible. For more information about Dilaudid detox or to find an addiction treatment center, browse our directory or reach out to the Substance Abuse and Mental Health Services Administration (SAMHSA).
