Overdose Information
Overdose Symptoms:
- Slowed or stopped breathing (respiratory depression)
- Extreme drowsiness, inability to wake up
- Pinpoint pupils
- Cold, clammy skin
- Limp muscles
- Bluish discoloration of lips or fingernails
- Loss of consciousness
- Coma
What to Do:
Seek immediate emergency medical attention. Call 911 or your local emergency number. Naloxone (Narcan) may be administered by trained personnel to reverse the effects of opioid overdose. Provide rescue breathing if necessary. Call 1-800-222-1222 (Poison Control) for additional guidance.
Drug Interactions
Major Interactions
- Benzodiazepines and other CNS depressants (e.g., other opioids, sedatives, hypnotics, general anesthetics, phenothiazines, tranquilizers, skeletal muscle relaxants, alcohol): Increased risk of profound sedation, respiratory depression, coma, and death.
- Monoamine Oxidase Inhibitors (MAOIs): Concomitant use or within 14 days of MAOI discontinuation can result in unpredictable, severe, or fatal reactions (e.g., serotonin syndrome, respiratory depression, coma).
Moderate Interactions
- Serotonergic drugs (e.g., SSRIs, SNRIs, TCAs, triptans, mirtazapine, tramadol, fentanyl, lithium, St. John's Wort): Risk of serotonin syndrome.
- Anticholinergic drugs (e.g., tricyclic antidepressants, antihistamines, antipsychotics, muscle relaxants): Increased risk of urinary retention and severe constipation.
- Diuretics: Opioids may reduce the efficacy of diuretics by causing release of antidiuretic hormone.
Minor Interactions
- Antihypertensives: May cause additive hypotensive effects.
Monitoring
Baseline Monitoring
Rationale: To establish baseline pain level and guide initial dosing.
Timing: Prior to first dose and regularly throughout therapy.
Rationale: To assess baseline respiratory function and identify risk for respiratory depression.
Timing: Prior to first dose.
Rationale: To assess baseline neurological status and identify risk for excessive sedation.
Timing: Prior to first dose.
Rationale: To assess baseline cardiovascular status.
Timing: Prior to first dose.
Rationale: To assess risk for opioid-induced constipation.
Timing: Prior to first dose.
Routine Monitoring
Frequency: Every 1-2 hours initially after parenteral administration, then every 4-6 hours or as clinically indicated.
Target: Patient-specific pain goal (e.g., 0-3/10 on a pain scale).
Action Threshold: Pain score above goal, requiring dose adjustment or rescue medication.
Frequency: Every 1-2 hours initially after parenteral administration, then every 4-6 hours or as clinically indicated.
Target: Typically >10-12 breaths/minute (adults), regular rhythm.
Action Threshold: Respiratory rate <10 breaths/minute, shallow breathing, or signs of hypoventilation (e.g., cyanosis, decreased SpO2).
Frequency: Every 1-2 hours initially after parenteral administration, then every 4-6 hours or as clinically indicated.
Target: Alert or mildly drowsy, easily aroused.
Action Threshold: Difficult to arouse, somnolent, or unarousable.
Frequency: Every 4-6 hours or as clinically indicated.
Target: Within patient's normal range.
Action Threshold: Significant hypotension or bradycardia.
Frequency: Daily
Target: Regular bowel movements (e.g., every 1-3 days).
Action Threshold: No bowel movement for >3 days, severe abdominal discomfort, or signs of ileus.
Symptom Monitoring
- Excessive sedation
- Respiratory depression (slow, shallow breathing)
- Pinpoint pupils (miosis)
- Dizziness
- Nausea/vomiting
- Constipation
- Pruritus
- Urinary retention
- Confusion
- Hypotension
Special Patient Groups
Pregnancy
Use during pregnancy is generally not recommended due to the risk of neonatal opioid withdrawal syndrome (NOWS) and potential for respiratory depression in the neonate. Use only if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
Hydromorphone is excreted into breast milk. While levels are generally low, there is a risk of sedation, respiratory depression, and withdrawal symptoms in the infant. Monitor infants for increased sleepiness, difficulty breathing, or limpness. Use with caution, or consider alternative analgesics.
Pediatric Use
Use with extreme caution, especially in infants and young children, due to increased sensitivity to respiratory depression. Dosing must be precise and based on weight. Not recommended for routine use in neonates.
Geriatric Use
Start with lower doses and titrate slowly due to increased sensitivity to opioid effects (e.g., respiratory depression, sedation, constipation) and potential for decreased renal/hepatic function. Monitor closely.
Clinical Information
Clinical Pearls
- Hydromorphone is 5-7 times more potent than morphine on a milligram-for-milligram basis when administered parenterally. Always double-check calculations to avoid overdose.
- Rapid onset and short duration make it suitable for acute pain management and titration.
- Patients with renal impairment are at higher risk for accumulation of hydromorphone-3-glucuronide (H3G), which can cause neuroexcitatory symptoms (e.g., myoclonus, delirium, seizures). Dose reduction is crucial.
- Always have naloxone readily available when administering hydromorphone, especially in opioid-naΓ―ve patients or during titration.
- Educate patients and caregivers about the signs of respiratory depression and overdose, and the importance of safe storage to prevent accidental ingestion.
- Proactive management of opioid-induced constipation (OIC) is essential from the start of therapy.
Alternative Therapies
- Morphine (parenteral)
- Fentanyl (parenteral)
- Oxycodone (parenteral, if available)
- Tramadol (parenteral, for less severe pain)
- Non-opioid analgesics (e.g., NSAIDs, acetaminophen) for mild to moderate pain or as adjuncts to opioids.
- Regional anesthesia/nerve blocks
- Patient-controlled analgesia (PCA) with hydromorphone or morphine.
