Methadone Withdrawal Symptoms: What to Expect and How to Taper Safely

Methadone withdrawal symptoms can start when you lower your dose or stop after taking it regularly. It often feels like a bad flu: aches, restlessness, sweating, an upset stomach, and poor sleep. Because methadone stays in your body a long time, symptoms build more slowly than with heroin or fentanyl, and they can last longer. The biggest risk comes afterward: once your tolerance drops, going back to opioids can cause an overdose. Below, we’ll cover what to expect, how a safe taper works, and how to protect yourself.

Why Methadone Withdrawal Is Different

Methadone is a long-acting opioid. It’s used to treat opioid use disorder, and sometimes for pain. The FDA label for Dolophine (methadone) puts its elimination half-life at 8 to 59 hours. That long, steady presence is what makes it useful in treatment. It also shapes withdrawal.

Because methadone stays in your body so long, withdrawal usually starts later and lasts longer than heroin withdrawal. According to MedlinePlus, symptoms usually begin within 12 hours of the last heroin use but within 30 hours of the last methadone dose. Here’s a general comparison:

Common Methadone Withdrawal Symptoms

Common withdrawal symptoms include:

• Restlessness and yawning
• Watery eyes and runny nose
• Sweating and chills
• Muscle aches and enlarged pupils

Other symptoms can develop too:

• Irritability and anxiety
• Back pain, joint pain, and weakness
• Stomach cramps, nausea, vomiting, and diarrhea
• Poor appetite and trouble sleeping
• Higher blood pressure, faster breathing, and a faster heart rate

Opioid withdrawal can be very uncomfortable, but it is not life-threatening on its own. It still carries real risks, though, including dehydration from vomiting and diarrhea, and what happens if you return to opioids.

The Real Danger: Losing Your Tolerance

Withdrawal fades, but your tolerance fades with it. Anyone who hasn’t taken opioids for more than 5 days may no longer be tolerant. After a taper or an abrupt stop, a dose you used to handle can slow your breathing enough to kill you.

The risk of relapse after stopping methadone maintenance is also high. And with fentanyl so common in the drug supply, a relapse can be especially dangerous. In Ohio, methadone was involved in 110 unintentional overdose deaths in 2023, while fentanyl and its analogs were involved in 78% of all overdose deaths in the state, according to the Ohio Department of Health’s 2023 overdose report.

If you’re tapering, or you’ve recently stopped:

• Keep naloxone (Narcan) where you and the people around you can reach it. It’s worth talking about naloxone access with your prescriber whenever methadone is started or renewed.
• Tell someone you trust that your tolerance is lower now.
• Have a plan for cravings before they hit.

How to Taper Off Methadone Safely

Stopping methadone suddenly is not recommended. For people on methadone maintenance, the recommended pace is specific: dose reductions should generally be less than 10% of the maintenance dose, with 10 to 14 days between each reduction.

At that pace, a full taper usually takes months. A safe taper:

• Is planned with your opioid treatment program (OTP), where methadone for opioid use disorder is dispensed
• Moves in small steps, with room to pause or slow down if symptoms get hard to manage
• Comes with counseling and a relapse-prevention plan
• Answers the question “Is now the right time?” first. Stopping maintenance carries a high risk of relapse, so that’s a decision to make with your provider.

When to Get Extra Support

Consider more support than your usual clinic visits if:

• You’ve tried to taper before and relapsed
• You’re thinking about stopping on your own
• You also use alcohol, benzodiazepines, or stimulants
• You’re dealing with depression, anxiety, or trauma alongside opioid use
