What’s the Difference Between Methadone and Suboxone?

Clinical Reviewer

Suboxone and methadone are two different medications that are both used to treat opioid use disorder.

Is Suboxone the same as methadone?

No, but they share many similarities in treating the same condition, opioid use disorder.

What is the difference between methadone and Suboxone?

Even though both help people with opioid use disorder, they are different medications.

Methadone is only dispensed at a methadone clinic.

Because it’s a full-agonist opioid, methadone is tightly regulated. Patients must report to a methadone clinic to get their dose dispensed to them. After several months of success, patients take home more methadone dosage over time and the requirement for check-ins end up similar to Suboxone eventually.

Suboxone can be filled at the pharmacy like any other medication, but pharmacies too often refuse to provide Suboxone. A Suboxone clinic can dispense onsite.

Suboxone is usually the first choice.

Suboxone is usually the first choice for opioid use disorder because it’s people are less likely to abuse it and the naloxone blocker prevents overdose in case they do. However, methadone has been successfully treating opioid addiction for years and is a good option if you’ve already had success with it. Some switch to methadone if they haven’t been successful with Suboxone or want the extra daily accountability.

Suboxone vs. Methadone FAQs

No, they are different medications with different ingredients. 

  1. Methadone only has one ingredient, methadone hydrochloride. 
  2. Suboxone is a combination of two medications, buprenorphine and naloxone.
It could be said that methadone is stronger since the medication fully activates the opioid receptor while Suboxone only partially activates it. Though, both medications satisfy the brain’s craving for opioids.  

Suboxone and methadone have similar side effects, including:

  • Constipation 
  • Nausea and vomiting
  • Drowsiness and fatigue
  • Dilated pupils
  • Insomnia
  • Sweating
  • Respiratory distress
  • Double-vision

The biggest difference is that Suboxone doesn’t cause the feel-good, euphoric feelings of traditional opioids. It’s less intense than heroin or fentanyl, but you can get high off of methadone, which is why it’s given only at a clinic.

Methadone and Suboxone are equally effective at treating opioid use disorder, though one study showed individuals on low doses of Suboxone (6 mg or less) are less likely to stay in treatment compared those taking methadone.

Can you take methadone and Suboxone together?

No, you have to choose either Suboxone or methadone. Combining both medications is dangerous because both are opioids and because Suboxone contains naloxone, an opioid blocker.

This combination could cause an opioid / methadone overdose, but will more likely lead to severe precipitated withdrawal symptoms.

Combining Suboxone with methadone will not give you a high or relief, but will likely cause you to feel absolutely terrible including 10/10 body pain and vomiting.

Should you switch from methadone to Suboxone?

If a patient is successfully treating their opioid addiction with methadone, there is no need to switch to Suboxone. But, if they continue to relapse or are non-compliant with the methadone program, Suboxone may be a better fit.

How To Switch From Methadone To Suboxone

A patient’s methadone dose should be tapered down to 30mg before starting Suboxone and Suboxone shouldn’t be taken until at least 24 hours after the last dose of methadone.
Those on a low methadone dosage can usually transition without noticing an increase in symptoms or cravings. In one study, all 25 out of 25 participants transitioned successfully.
That said, withdrawals often lead to relapse, so the switch should be carefully coordinated by your doctor(s). 

Should you switch from Suboxone to methadone?

It’s not as common to switch from Suboxone to methadone, but can be a good option when patient’s aren’t successful on Suboxone

How To Switch From Suboxone To Methadone

Switching from Suboxone to methadone is easier because methadone does not have an opioid blocker. Methadone should be started 24 hours after the last dose of Suboxone. The initial dose of methadone will be adjusted based on the patient’s last Suboxone dose.

  1. I have been on Suboxone for about 6 years taking a little bit of a strip daily now. I got some methadone to get off subs. Will this work?

    1. If your goal is to get off medications, keep tapering down instead. Don’t just stop taking Suboxone but have patience. No need to get methadone involved when it sounds like you’re almost there! The end of the tapering process can be difficult when it comes to Suboxone. It is helpful to speak with your Suboxone treatment provider about being prescribed temporary medications to use as needed for any withdrawal symptoms that develop after completely stopping it. Since methadone itself is an opioid, it can cover up the withdrawals from Suboxone but they will return when you stop taking the methadone too.

  2. I have been on Suboxone for 1 month, but I want to go back to the methadone program because I don’t like the way I feel on Suboxone. Is that possible? And how long do I have to wait to take the methadone?

    1. Yes, you can switch back. Methadone can be started 24 hours after the last dose of Suboxone. The initial dose of methadone should be adjusted based on your last Suboxone dose. Your methadone program will explain in more detail.

      That said, you may want to talk to your Suboxone provider before making the switch. It might be that you’re not at your ideal dosage of Suboxone yet or your body just needs more time to adjust.

    2. I just changed back to methadone from Suboxone. I had to restart methadone dosing, but getting back to it. Good luck!

    3. Im on 310 mg methadone and still using fentanyl meth and occasional benzo use but i’m finally about stable and wondering how much longer i can expect to keep raising my dose?

  3. Can I have methadone even though I’ve been on 32mg of Suboxone for about 6 mths? If I only have 25ml of methadone will I go into instant withdrawal?!

    1. You won’t go into withdrawal, but that’s a really high amount of Suboxone. You’d be at high risk of an overdose by adding methadone on top. Please don’t do it!

      Instant withdrawals, known as “precipitated withdrawals” occur in the opposite scenario of taking Suboxone when your body is already physically dependent on opioids (including methadone).

  4. I’m on 34 mg of methadone. I’m switching to Suboxone and I have been clean for 9 years. How much Suboxone should I need?

    1. You will need to be in moderate withdrawal from methadone before you can start Suboxone. Otherwise, you may go into precipitated withdrawal (instant 10/10 opiate withdrawal). You may want to consider tapering off the methadone slowly then discuss naltrexone/Vivitrol with your provider as it will block opiate cravings but you will not become dependent on it.

      If you do go to Suboxone, there’s no equivalent dose of methadone to Suboxone. You’ll just need to find the dose that prevents withdrawal symptoms and minimizes cravings.

  5. My program will NOT let me go back on the methadone from the Suboxone that the jail put me. I’m 64 with a lot of chronic pain. I don’t know what to do.

    1. So sorry to hear that! Did they give you any reason for not being able to switch? Are there any other methadone programs near you?
