Drug Guide

Generic Name

Hydromorphone Hydrochloride

Brand Names Dilaudid-hp, Dilaudid, Palladone, Exalgo

Classification

Therapeutic: Analgesic, Opioid

Pharmacological: Opioid Receptor Agonist

FDA Approved Indications

  • Moderate to severe pain management

Mechanism of Action

Hydromorphone binds primarily to mu-opioid receptors in the central nervous system, altering the perception and response to pain.

Dosage and Administration

Adult: Typically, 2-4 mg orally every 4-6 hours as needed; IV dose varies based on clinical judgment.

Pediatric: Use is generally discouraged due to risk of respiratory depression.

Geriatric: Start at lower doses due to increased sensitivity; monitor closely.

Renal Impairment: Adjust dose considering reduced clearance; cautious use recommended.

Hepatic Impairment: Modify dose as hepatic metabolism is affected.

Pharmacokinetics

Absorption: Well absorbed orally; rapid onset when given parenterally.

Distribution: Widely distributed, crosses blood-brain barrier, crosses placenta.

Metabolism: Metabolized in the liver via conjugation to hydromorphone-3-glucuronide.

Excretion: Excreted primarily in urine.

Half Life: Approximately 2-3 hours.

Contraindications

  • Hypersensitivity to hydromorphone or any opioids.
  • Acute respiratory depression.
  • Severe asthma.

Precautions

  • Use with caution in patients with respiratory depression, head injury, increased intracranial pressure, multiple opioid use, or in elderly and patients with hepatic or renal impairment.
  • Pregnancy/Lactation: Use only if benefits outweigh risks; crosses placenta and is excreted in breast milk.

Adverse Reactions - Common

  • Drowsiness (Common)
  • Nausea (Common)
  • Constipation (Common)
  • Dizziness (Common)

Adverse Reactions - Serious

  • Respiratory depression (Serious)
  • Hypotension (Serious)
  • Addiction, overdose, death (Serious)

Drug-Drug Interactions

  • CNS depressants (benzodiazepines, alcohol)
  • MAO inhibitors
  • Other opioids

Drug-Food Interactions

  • Alcohol (increases sedation and respiratory depression)

Drug-Herb Interactions

N/A

Nursing Implications

Assessment: Assess pain level and respiratory status before and during therapy.

Diagnoses:

  • Acute pain
  • Risk for respiratory depression

Implementation: Administer drug as prescribed; monitor for adverse effects; use the lowest effective dose.

Evaluation: Evaluate pain relief and monitor for signs of toxicity or adverse reactions.

Patient/Family Teaching

  • Take medication exactly as prescribed.
  • Avoid alcohol and other CNS depressants.
  • Report signs of respiratory depression, excessive sedation, or allergic reactions.
  • Use caution when driving or operating machinery.

Special Considerations

Black Box Warnings:

  • Addiction, abuse, and codevelopment of overdose leading to death.
  • Risks related to use during pregnancy and in breastfeeding.
  • Respiratory depression risk.

Genetic Factors: Genetic variations may affect metabolism and response.

Lab Test Interference: May cause increase in liver enzymes, but generally no significant interference.

Overdose Management

Signs/Symptoms: Respiratory depression, pinpoint pupils, unconsciousness, cold/clammy skin.

Treatment: Administer opioid antagonist (naloxone), support airway, breathing, and circulation; provide symptomatic treatment.

Storage and Handling

Storage: Store at room temperature, away from light and moisture.

Stability: Stable under recommended storage conditions.

🛡️ 5 Critical Medication Safety Tips for Nurses

1

Triple-Check High-Risk Medications

Always have another nurse verify insulin, heparin, warfarin, and chemotherapy drugs. These "high-alert" medications cause the most serious errors. Check concentration, dose calculation, and pump settings twice.

2

Know Look-Alike, Sound-Alike Drugs

Common mix-ups: hydromorphone/morphine, Celebrex/Celexa, Zyprexa/Zyrtec. Always use BOTH generic and brand names, read labels twice, and use barcode scanning when available. One wrong letter can be fatal.

3

Assess Before AND After Giving Meds

Check vitals before cardiac meds, pain levels before analgesics, and blood glucose before insulin. Always reassess within 30 minutes to evaluate effectiveness and watch for adverse reactions.

4

Watch for Drug Interactions

Common dangerous combinations: warfarin + aspirin (bleeding), ACE inhibitors + potassium (hyperkalemia), digoxin + diuretics (toxicity). Always check drug interactions before administering new medications.

5

Educate Your Patients

Teach patients medication names, purposes, major side effects, and what to report. Informed patients catch errors and improve compliance. Always encourage questions - an educated patient is a safer patient.

⚡ Remember: When in doubt, don't give it out! It's always safer to double-check than regret later.
