📚 Opioid Withdrawal — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Opioid withdrawal results from stopping or reducing opioids in a dependent person, producing intensely uncomfortable but rarely life-threatening symptoms (in contrast to alcohol or benzodiazepine withdrawal). Symptoms resemble a severe flu. Management includes comfort medications, clonidine, and medication-assisted treatment with methadone or buprenorphine.
GI symptoms include nausea, vomiting, abdominal cramping, and diarrhea.
Other signs are dilated pupils (mydriasis), piloerection (gooseflesh), restlessness, and insomnia.
Opioid withdrawal is extremely distressing but rarely directly fatal in healthy adults.
Dehydration from vomiting and diarrhea is the main physical danger.
Clonidine reduces autonomic symptoms; methadone and buprenorphine ease withdrawal and craving.

Nursing priorities
What to do, in order
Assess withdrawal severity (e.g., COWS scale) and monitor hydration and vital signs.
Administer prescribed comfort medications: clonidine, antiemetics, antidiarrheals, and analgesics.
Provide medication-assisted treatment such as methadone or buprenorphine as ordered.
Replace fluids and electrolytes lost to vomiting and diarrhea.
Offer emotional support and connect the client to recovery and counseling resources.
🚩
Red flags — report now
Escalate immediately
Severe vomiting and diarrhea can cause dangerous dehydration and electrolyte loss requiring prompt fluids.
Buprenorphine given too early can precipitate acute withdrawal - confirm appropriate timing.
Pregnant clients in opioid withdrawal risk fetal harm and need specialized management.
Naloxone reversal can trigger sudden severe withdrawal and must be monitored.

Labs & values
Numbers to know
Potassium 3.5-5.0 mEq/L (monitor with vomiting/diarrhea)
Sodium 135-145 mEq/L (monitor for dehydration)

Patient teaching
What patients must know
Withdrawal is temporary; medication-assisted treatment greatly reduces discomfort and relapse.
Stay hydrated and use prescribed comfort medications as directed.
Reduced tolerance after detox makes relapse overdose deadly; carry naloxone and engage support.
