Key takeaway
Morphine withdrawal can bring muscle aches, nausea, diarrhea, insomnia, and intense cravings. It is rarely fatal by itself but drives relapse and overdose risk when people return to use. Call or text (800) 653-9376 for MOUD and detox help.

Morphine is a full opioid agonist. When regular use stops, the body reacts with a predictable withdrawal syndrome - miserable, relapse-driving, and safest when managed with a plan.
For overdose (slow breathing, blue lips, unresponsiveness), call 911 and give naloxone. Call or text 988 for a crisis.
Typical morphine withdrawal symptoms
- Flu-like chills, sweating, goosebumps, runny nose, yawning
- Muscle and bone aches
- Nausea, vomiting, diarrhea, stomach cramps
- Anxiety, restlessness, insomnia
- Intense cravings
Symptoms often start within roughly a day after the last dose, peak over the next several days, and then improve - though sleep and mood can lag.
Treatment that actually lowers risk
NIDA is clear that methadone and buprenorphine reduce mortality compared with no medication. Naltrexone is an option only after opioids have cleared.
Comfort medicines (anti-nausea, clonidine in some protocols, sleep support) can help symptoms but are not a substitute for MOUD when opioid use disorder is present.
Relapse and overdose warning
After even a short abstinence, tolerance drops. Returning to a prior morphine or fentanyl dose can be fatal. Naloxone access matters during any attempt to stop.
Next step
Search FindTreatment.gov for buprenorphine or OTP care, ask your clinician about induction timing, or call or text (800) 653-9376.

Common Questions
What are morphine withdrawal symptoms?
Common symptoms include yawning, runny nose, goosebumps, sweating, muscle aches, nausea, vomiting, diarrhea, anxiety, insomnia, and strong cravings. Severity tracks dose and duration of use.
How long does morphine withdrawal last?
Flu-like acute symptoms often begin within about a day of the last dose and peak in the first few days, then ease over about a week for many people. Sleep and mood symptoms can last longer.
Is morphine withdrawal deadly?
Uncomplicated opioid withdrawal is rarely fatal by itself, but dehydration, medical complications, and relapse to a lower-tolerance dose after abstinence can be dangerous. Seek care rather than white-knuckling alone if you are unstable.
What medications help?
Buprenorphine and methadone treat opioid withdrawal and reduce overdose risk. Naltrexone is an option only after opioids have fully cleared. Comfort meds alone are not a full MOUD plan.
Where can I start?
Call 911 for overdose (slow breathing, unresponsiveness) and give naloxone. Call or text 988 for a crisis. Search FindTreatment.gov for buprenorphine/OTP care or call or text (800) 653-9376.
