How Long Does Opioid Withdrawal Last? A Complete Timeline
Quick Answer: Opioid withdrawal commonly lasts about 3–5 days for short-acting opioids, while withdrawal from longer-acting opioids may last 10 days or longer. The exact timeline depends on the opioid used, how long and how frequently it was taken, the amount used, and individual health factors.

What Is Opioid Withdrawal?
Opioid withdrawal is the collection of physical and psychological symptoms that can develop when someone who has become physically dependent on opioids suddenly stops or significantly reduces their use.
Opioids can include heroin, fentanyl, oxycodone, hydrocodone, morphine, methadone, and other prescription or illicit substances.
Withdrawal occurs because the body has adapted to the presence of opioids. When the drug is removed, the nervous system needs time to adjust, producing symptoms such as anxiety, muscle aches, sweating, nausea, diarrhea, insomnia, and cravings.
What Is the Opioid Withdrawal Timeline?
How long do opioid withdrawal symptoms last? It depends on the individual, but there are some trends we can observe.
The opioid withdrawal symptoms timeline typically begins within hours to about a day after the last dose, becomes most intense during the first several days, and gradually improves afterward. Short- and long-acting opioids can produce noticeably different timelines.
6–24 Hours After the Last Dose
Early withdrawal symptoms may begin within approximately 12 hours for short-acting opioids such as heroin and oxycodone.
Early symptoms can include:
- Anxiety or restlessness
- Muscle aches
- Sweating
- Runny nose
- Watery eyes
- Yawning
- Difficulty sleeping
Symptoms may initially feel similar to anxiety, a cold, or the flu before becoming more noticeable.
24–48 Hours
Withdrawal from short-acting opioids often reaches its greatest intensity within 24–48 hours after the last use.
Symptoms during this stage can include nausea, vomiting, diarrhea, abdominal cramps, dilated pupils, goosebumps, worsening muscle pain, insomnia, and strong opioid cravings. Maintaining hydration can also become difficult when vomiting or diarrhea is significant.
Days 3–5
Acute withdrawal from short-acting opioids generally begins improving within 3–5 days.
Physical symptoms such as gastrointestinal distress, sweating, and body aches may decrease, although sleep problems, fatigue, anxiety, and cravings can continue. Improvement doesn’t necessarily mean the risk of returning to opioid use has passed.
Days 5–10 and Beyond
Long-acting opioids can produce a later and longer withdrawal period. Methadone withdrawal, for example, may begin within roughly 30 hours of the last exposure and continue for up to 10 days.
Some people continue experiencing sleep disturbances, low mood, anxiety, low energy, or cravings after the most intense physical symptoms resolve. Recovery timelines vary considerably between individuals.
What Affects How Long Opioid Withdrawal Lasts?
Several factors can change how long opioid withdrawal lasts and how severe symptoms become. The specific opioid is especially important because short-acting substances generally produce earlier withdrawal than long-acting ones.
Other factors include:
- Length and frequency of opioid use
- Typical dose
- Method of use
- Degree of physical dependence
- Use of multiple substances
- Physical health
- Mental health conditions
- Previous withdrawal experiences
Because these factors interact, two people using the same opioid may experience substantially different withdrawal symptoms and timelines.
Is Opioid Withdrawal Dangerous?
Opioid withdrawal is generally not considered life-threatening by itself, but complications and relapse can create serious risks. Severe vomiting and diarrhea can cause dehydration and electrolyte problems, while returning to opioid use after detox can lead to overdose because tolerance may have decreased.
For that reason, attempting withdrawal without professional guidance may not be the safest approach. Medical monitoring can help assess symptoms, address complications, and determine which treatments are appropriate.
How Is Opioid Withdrawal Treated?
Opioid withdrawal can be treated with medical monitoring, symptom management, supportive care, and, when clinically appropriate, medications. The specific approach should be based on the individual’s opioid use, withdrawal severity, health history, and broader treatment needs.
At Monterey Bay Recovery, our drug detox program provides structured medical support for people withdrawing from substances, including opioids. Our medical team monitors each person’s progress and may use medication-assisted approaches when clinically appropriate to help manage withdrawal symptoms and cravings.

FAQs: How Long Does Opioid Withdrawal Last?
Can opioid withdrawal symptoms come and go?
Yes. Withdrawal symptoms don’t always improve in a perfectly steady pattern. A person may feel better for a period and then notice certain symptoms, such as anxiety, sleep problems, or cravings, return temporarily.
Does tapering opioids change how long withdrawal lasts?
It can. A medically supervised taper may reduce the intensity of withdrawal by lowering the opioid dose gradually, but the overall process may take longer than stopping suddenly.
Does medication affect the opioid withdrawal timeline?
Yes. Medications used during opioid withdrawal can change how symptoms develop and how manageable they feel. The exact opioid withdrawal symptoms and timeline depend on the medication used, the opioid involved, and the treatment plan.
When should I be concerned that opioid withdrawal is lasting too long?
You should seek medical guidance if symptoms are severe, worsening, or lasting longer than expected. Persistent vomiting, dehydration, significant mood changes, or difficulty functioning may require professional evaluation.
Can opioid withdrawal start again after symptoms improve?
Some symptoms can reappear after the acute phase, especially sleep disturbances, anxiety, low mood, fatigue, or cravings. This doesn’t necessarily mean acute withdrawal has restarted, but it may be part of the longer recovery process.
