Your opioid withdrawal timeline depends on whether you’re stopping a short-acting or long-acting opioid. With short-acting opioids, symptoms typically begin 6, 12 hours after your last dose, peak around days 2, 3, and last 5, 10 days. With long-acting opioids, onset is delayed to 1, 3 days, peaks between days 3, 8, and can last 10, 20+ days. Dose, duration, and route also shape your experience. Understanding each phase helps you know what’s coming next.
Key Takeaways
- Short-acting opioids trigger withdrawal 6, 12 hours after the last dose, while long-acting opioids delay onset to 1, 3 days.
- Early symptoms resemble a bad flu, including anxiety, restlessness, yawning, runny nose, watery eyes, sweating, and insomnia.
- Short-acting withdrawal peaks around days 2, 3 and lasts 5, 10 days total.
- Long-acting withdrawal peaks between days 3, 8 and can last 10, 20+ days, sometimes with delayed worsening.
- Peak symptoms include nausea, vomiting, diarrhea, cramping, muscle aches, and rapid heart rate, making medical supervision important.
What is the opioid withdrawal timeline
The opioid withdrawal timeline depends heavily on the type you’ve been using, because different opioids leave your body at different rates. If you’ve been using a short-acting opioid like heroin, morphine, or immediate-release oxycodone, symptoms often begin 6, 12 hours after your last dose, peak around days 2, 3, and ease within 5, 10 days. If you’ve been using a long-acting opioid like methadone or an extended-release formulation, onset is delayed, typically 1, 3 days, and symptoms peak later, around days 3, 8, sometimes lasting 10, 20 days or longer.
Your dose, duration of use, and route of administration also shape how quickly symptoms start and how intense they become. Understanding this timeline helps you anticipate the hardest phases and stay engaged with support long enough to recover.
What early opioid withdrawal symptoms are
Early opioid withdrawal symptoms feel a lot like the onset of a bad flu. In these early hours, you might experience anxiety, restlessness, and frequent yawning. You could also notice a runny nose, watery eyes, and sweating, along with trouble falling or staying asleep. For short-acting opioids like heroin or immediate-release oxycodone, these symptoms often begin 6, 12 hours after your last dose. With long-acting opioids like methadone, onset typically comes later, sometimes 1, 3 days out. These early signs tend to feel uncomfortable but manageable compared to what follows. As you move toward the peak, symptoms usually intensify rather than stay constant, so recognizing this early phase helps you prepare and seek support before things worsen.
How short-acting and long-acting opioids differ in timing
Short-acting and long-acting opioids differ in timing because of how long each drug stays in your body. Short-acting opioids like heroin, morphine, and immediate-release oxycodone or hydrocodone leave your system quickly, so you’ll usually notice symptoms within 6, 12 hours of your last dose. They peak around days 2, 3 and ease within 5, 10 days.
Long-acting opioids, including methadone and extended-release formulations, clear more slowly, delaying onset to 1, 3 days. Your symptoms tend to peak later, often around days 3, 8, and can last 10, 20 days or longer.
This delayed onset matters. If you’re stopping a long-acting opioid, you might feel fine at first, then worsen days later, so don’t assume you’ve avoided withdrawal too soon.
How the full timeline compares across opioids
The full timeline differs significantly across opioids. Short-acting opioids like heroin move fast: symptoms start within 6, 12 hours, peak around days 2, 3, and ease within 5, 10 days. Long-acting opioids like methadone stretch everything out, beginning 1, 3 days after your last dose, peaking around days 3, 8, and lasting 10, 20 days or longer.
| Phase | Short-Acting | Long-Acting |
|---|---|---|
| Onset | 6, 12 hours | 1, 3 days |
| Peak | Days 2, 3 | Days 3, 8 |
| Duration | 5, 10 days | 10, 20+ days |
Seeing these side by side helps you understand why long-acting withdrawal feels harder to anticipate. If you’re waiting for symptoms that seem delayed, you’re not imagining it. Your timeline simply depends on which opioid you used.
What the peak of withdrawal involves
The peak marks the most intense stretch of withdrawal, when symptoms intensify rather than hold steady. If you’ve used a short-acting opioid like heroin, you’ll likely hit the peak around days 2, 3. With long-acting opioids like methadone, the peak comes later, often between days 3 and 8. During this window, you may face nausea, vomiting, diarrhea, abdominal cramping, muscle aches, goosebumps, dilated pupils, and a rapid heart rate. Anxiety and sleep problems often persist too. Because this stage is so uncomfortable, it’s when relapse risk climbs. Medical supervision, hydration, and medications can ease your symptoms and help you stay in treatment until things improve.
Why medically supervised detox matters
Medically supervised detox matters because withdrawal symptoms intensify unpredictably, giving you a safer way to manage the hardest stretches. When you’re coming off short-acting opioids, symptoms can peak around days 2, 3, while long-acting opioids like methadone often peak later, between days 3, 8. Supervised care lets clinicians track your symptoms using tools like the COWS and respond as they escalate.
You’ll get support for dehydration, nausea, diarrhea, sleep problems, and muscle aches before they become dangerous. Medications for opioid withdrawal and opioid use disorder can ease your discomfort and help you stay in treatment. Supervision also matters because delayed onset with long-acting opioids can catch you off guard. If severe symptoms, chest pain, confusion, or suicidal thoughts appear, you’ll have immediate access to care.

Can I Detox From Opioids Safely at Home?
Detoxing at home isn’t the safest choice, especially with long-acting opioids like methadone, where symptoms peak later and last longer.
