Dilaudid (hydromorphone) is a powerful prescription opioid that is five times stronger than morphine. Similar to other pain relievers and opioids, Dilaudid causes sedation and a euphoric high. People who abuse Dilaudid may take the drug orally, crush the tablets into a fine powder for snorting, mix the powder into a solution for intravenous drug abuse, or mix the powder with sterile water for rectal administration (plugging).

These methods of abuse increase the rate at which the drug enters the bloodstream and produces effects. Rectal administration of Dilaudid is more common among people who have a substance use disorder, and those that have established addiction to other opiate medications. Plugging drugs may lead to higher and dangerous levels of bioavailability and blood concentration levels of the drug in a short period of time.

Furthermore, opioid prescription drugs, such as OxyContin, oxycodone, and Dilaudid are well-known for causing severe addiction in people who use them. Opioid abuse through methods such as plugging increases the risk for addiction, dependency, overdose, and other adverse effects.

What Is Plugging Dilaudid?

Plugging Dilaudid is the process of administering the drug through the rectum into the small intestine for faster and stronger effects. Plugging the drug leads to an increased level of the drug’s bioavailability and greater absorption in the body.

People who administer the medication anally will crush the drug into a fine powder to mix with sterile water. The solution is then injected into the body with the use of a syringe. This method of abuse has become increasingly popular for recreational abuse as a suppository. It is more dangerous than other methods of administration, as less of the drug is needed to produce strong effects.

Why People Plug Dilaudid

People who plug Dilaudid do so primarily to intensify and accelerate the drug’s effects compared to taking it orally. When Dilaudid is inserted rectally, it bypasses the digestive system and is absorbed directly into the bloodstream through rectal tissue, producing a faster and more intense high. Rectal administration has higher bioavailability than oral use, meaning more of the drug reaches the brain quickly, creating stronger euphoric effects.

Some individuals turn to plugging after developing tolerance to oral doses and finding that swallowing pills no longer produces desired effects. Others may have heard that rectal administration maximizes the high using a smaller amount of drug. People trying to hide drug use may choose this method because it doesn’t leave visible track marks like injection. Some who experience severe nausea from taking opioids orally may resort to plugging as an alternative.

Side Effects Of Plugging Dilaudid

Plugging Dilaudid may cause a range of severe side effects and health problems caused by improper anal administration and due to the drug itself.

People who plug Dilaudid may use unsterile syringes and high doses of the medication.

Plugging Dilaudid may cause the following side effects:

  • rectal infections and irritation
  • constipation
  • exposure to disease via contaminated syringe
  • overdose
  • death

Dilaudid may cause a wide range of short and long-term effects when administered rectally. These effects are similar to those of heroin, morphine, and fentanyl.

Short-term effects of Dilaudid abuse may include:

  • euphoria
  • relaxation
  • mood swings
  • drowsiness
  • nausea
  • vomiting
  • mental impairment and loss of coordination
  • slow heartbeat
  • respiratory depression or failure
  • changes in blood pressure

Long-term abuse of Dilaudid may cause chemical dependency, drug tolerance, addiction, brain damage, coma, respiratory failure, overdose, and death.

Dilaudid Overdose

When a person takes high doses of this medication, it can lead to a fatal opioid overdose. Combining Dilaudid with other prescription medications, such as other opioids, benzodiazepines, or alcohol may quickly lead to death.

If someone shows the following symptoms and signs after taking Dilaudid, emergency medical assistance is required:

  • difficulty breathing
  • loss of consciousness
  • weakness and confusion
  • constricted pupils
  • confusion
  • cold, clammy skin
  • coma

Dilaudid Addiction And Withdrawal

Dilaudid substance use leads to a release of endorphins and increased dopamine in the body, which causes a euphoric high and numbs pain. After habitual use, the body becomes reliant on these effects in order to regulate itself.

Once a person has a physical dependence on the medication, they will experience withdrawal symptoms when stopping the drug. Severe withdrawal symptoms may lead an individual to continue abusing the drug in order to avoid them. Like other opioid painkillers, Dilaudid addiction and its associated withdrawal symptoms can be potentially dangerous if not supervised and treated by medical professionals.

Symptoms of Dilaudid withdrawal may include:

  • excessive sweating
  • flu-like symptoms
  • insomnia
  • diarrhea
  • muscle pain
  • nausea and vomiting
  • depression

In severe cases of withdrawal, people may require intensive inpatient monitoring and medical support. Those who want to stop taking Dilaudid after becoming addicted to the drug should consult with a qualified healthcare provider.

Dilaudid Addiction Treatment

People who have become addicted to Dilaudid should seek medical advice and treatment from qualified medical professionals in a rehab setting. Medical supervision and treatment will ensure an individual can safely detox and achieve recovery. Dilaudid withdrawal symptoms may be severe. It is not recommended to stop drug use abruptly after chemical dependency is established, as a gradual tapering-down method may be required to safely detox from the drug.

Substance abuse treatment will provide necessary medical interventions, including medications such as naloxone or methadone, when appropriate and necessary. Each case is evaluated on an individual basis and treatment options are tailored for the individual’s unique needs. Without medical intervention and support, a person may remain at increased risk of overdose and adverse side effects.
