Hydromorphone is a potent opioid analgesic (brand name Dilaudid, among others). It’s used to treat moderate to severe pain and is available in several forms (oral immediate-release and extended-release tablets, oral solution, and injectable forms like IV, IM, or subcutaneous).
Key points:
- How it works: It binds to mu-opioid receptors in the brain to reduce the perception of pain.
- Potency: Hydromorphone is stronger per milligram than morphine. This means dosing is more sensitive and inappropriate dosing can quickly cause serious respiratory depression.
- Uses: Often used for severe pain, including after surgery or in cancer pain, and sometimes for opioid-tolerant patients who need strong analgesia.
- Forms and routes: Oral tablets or liquid; extended-release oral forms for longer-term pain; injections (IV/IM/subcutaneous) for quicker relief or in a hospital.
Safety and precautions:
- Critical risks: Respiratory depression, severe drowsiness, coma. The risk increases with alcohol, sedatives, or other opioids.
- Common adverse effects: Constipation, nausea, vomiting, dizziness, drowsiness, sweating, itching.
- Dependence and withdrawal: Can cause physical dependence and withdrawal symptoms if stopped abruptly after regular use.
- Contraindications: Known allergy to hydromorphone; severe respiratory impairment or acute/severe bronchial asthma without monitoring; other serious conditions that would be worsened by opioid effects.
- Special populations: Use in pregnancy requires weighing benefits and risks; discuss with a clinician. Breastfeeding while taking hydromorphone can pass to the infant.
Interactions:
- Avoid or use with caution with alcohol, benzodiazepines, other central nervous system depressants, or drugs that affect kidney/liver function.
- Certain drug interactions can increase sedation or respiratory depression.
Dosing:
- Dosing is highly individualized based on prior opioid exposure, pain severity, and liver/kidney function. It should be prescribed and adjusted by a healthcare professional.
- Do not adjust or start new regimens without medical advice. If you have a prescription, follow the label and your clinician’s instructions carefully.
