MAJOR — Use With Caution
DANGEROUS — naltrexone blocks all opioid effects; precipitates withdrawal in dependent patients
Evidence level: STRONG
Naltrexone completely blocks the effects of hydrocodone. If you are physically dependent on opioids, naltrexone will cause immediate severe withdrawal.
Naltrexone is an opioid antagonist that blocks mu-opioid receptors. It blocks opioid analgesic effects and can precipitate severe withdrawal in opioid-dependent patients.
Must be opioid-free for 7-10 days before starting naltrexone. In emergencies requiring pain control, higher opioid doses may be needed to overcome blockade (specialist supervision only).
Take Hydrocodone exactly as prescribed — set alarms for scheduled doses. Naltrexone follows its normal schedule. Opioids slow GI transit, which can affect absorption of other medications. Take with food if nausea occurs. Never combine with alcohol.
Opioid physical dependence, recent opioid use within 7-10 days, need for pain management
Precipitated withdrawal (severe nausea, vomiting, diarrhea, muscle pain, anxiety), or complete loss of pain relief
Ensure adequate opioid washout period. Carry medical alert card stating naltrexone use.
Opioid combinations carry serious risks including respiratory depression. Talk to your pain management specialist about non-opioid alternatives: physical therapy, NSAIDs (if appropriate), nerve blocks, or non-sedating supplements like PEA (palmitoylethanolamide) or curcumin for inflammation.
