Medications used under the care of a medical professional are an important part of the treatment for opioid use disorder. The newest form of medication treatment is called Medication-Assisted Treatment (MAT).
MAT combines specific medications (methadone, buprenorphine, or naltrexone) with counseling and short-term therapies focused on changing patterns of thinking and taking positive action. These medications are safe to use short or long-term.
The main goal of MAT is to help people stay in recovery and prevent opioid overdose. It is used to block the “high” from opioids, reduce cravings and help the brain and body heal.
Medications can be used to lessen withdrawal symptoms, prevent relapse, and treat both addiction and related mental health issues.

What They Do
- Ease withdrawal: One reason people keep taking opioids is to avoid the discomfort of withdrawal. Medications help ease withdrawal symptoms during detox. But detox is only the first step. If you do not receive treatment and support after detox you are more likely to start using opioids again.
- Prevent relapse: Medications can be used to decrease cravings and help your brain and body return to normal after stopping drug use. Each drug, such as heroin and prescription opioid drugs, is treated by a specific medication. If you use more than one drug you need treatment for each of the drugs you use.
- Help with other mental health problems: Medications can help treat depression or anxiety, which can contribute to opioid addiction.

Do They Work?
Strong evidence shows that methadone, buprenorphine, and naltrexone all reduce opioid use and help people stay in treatment.
Buprenorphine and methadone do not produce a "high" and lessen withdrawal symptoms and cravings. People can live normally while taking them. They can work, go to school, and take part in other forms of treatment and support to help their recovery.
If the goal is to wean off the maintenance medication, it should be done slowly while working with a treatment provider. It may take months or even years for brain circuits to recover from long-term drug use. These medications provide the support that is needed during this time. In cases of serious and long-term opioid use, a person may need these supports indefinitely.
BUPRENORPHINE
Buprenorphine was approved by the FDA in 2002 as a new treatment for opioid addiction. It is the first approved narcotic drug for addiction that can be prescribed by doctors in their offices. Since 2002 it has been available as a tablet and since 2010 as a film put under the tongue. In 2016 the FDA approved a 6-month buprenorphine implant and in 2017 a once-a-month buprenorphine injection. Both are available to patients stabilized on buprenorphine, so daily doses are not needed.
Different Forms:
- Bunavail (buprenorphine and naloxone): a small rectangular film you place inside your cheek, where it dissolves. It contains the drugs buprenorphine and naloxone.
- Buprenex: a form of buprenorphine that is injected.
- Butrans: a medicated adhesive patch that is placed on the skin containing buprenorphine. Use these patches exactly as directed by your doctor.
- Subutex: buprenorphine in tablet form that is dissolved under the tongue.
- Zubsolv (buprenorphine and naloxone): tablets that you dissolve under your tongue.
- Sublocade: a once-a-month injection of buprenorphine. Patients must be started on Zubsolv or Subutex before taking Sublocade.
What it does: Buprenorphine has major advantages over methadone or naltrexone. It is more effective at reducing drug cravings than naltrexone. While methadone is usually prescribed daily, buprenorphine is only needed every other day and there is a lower risk of overdose compared to methadone. Subutex is used in the first few days a person starts treatment.
How it works: Opioids attach to receptors in the brain, but they are not a perfect fit. Buprenorphine stimulates these opiate receptors but not strongly enough to produce the “high” that opioids would. Because of this it helps to ease withdrawal symptoms and drug cravings. If a user tries to take another opioid such as heroin while taking buprenorphine, there will be no effect.
Side effects: Headaches, flu-like symptoms, dizziness, constipation, upset stomach, sleep problems.
Note: It can cause dependence and withdrawal symptoms when stopped.

Sixteen studies of buprenorphine maintenance treatment (BMT) show it helps people stay in treatment and reduces illegal opioid use. BMT has a lower risk of side effects events than methadone and may improve the health of mother and baby during pregnancy compared with no medication-assisted treatment. Thomas CP 2014
NIDA's Clinical Trials Network Prescription Opioid Addiction Treatment Study (POATS)
In this large study on prescription opioid addiction, more than 600 outpatients received Suboxone and brief medical management. About 49% of patients reduced prescription painkiller abuse during 12-weeks of Suboxone treatment. This success rate dropped to 8.6% once Suboxone was no longer used. "The study suggests that patients addicted to prescription opioid painkillers can be successfully treated in primary care settings using Suboxone," said NIDA Director Nora D. Volkow, M.D. November, 2011.

METHADONE
What it does: Methadone is a long acting medicine that reduces cravings and blocks the effect of opioids. It prevents withdrawal symptoms in people who are now in a treatment program.
How it works: It turns on opioid receptors in the brain – but it does it more slowly than other opioids so it doesn’t produce a high. This lets you slowly detox without withdrawal symptoms or cravings. Because its effects last between 24 and 36 hours, most people can take just one daily dose.
Side effects: Drowsiness, weakness, nausea, constipation, headache, loss of appetite.
For a more complete list of side effects visit this NIH page.
Availability: Physician prescription. Methadone is not available through a local pharmacy. Patients must visit a special outpatient treatment provider or clinic. Click here for a list of methadone clinics by state.

In this large review, methadone was found to be better than buprenorphine in helping people stay in treatment, and as effective as buprenorphine in preventing illegal opioid use. Mattick RF 2014
See the National Institute of Drug Abuse research report “Medications to Treat Opioid Use Disorder". The report covers research on methadone, buprenorphine and naltrexone as treatments for opioid use disorder.
NALTREXONE (ReVia®, Vivitrol®, Depade®)
What it does: Naltrexone blocks opioid receptors in the brain from being turned on. Instead of controlling withdrawal and cravings, it prevents any opioid drug from producing a high.
How it works: It blocks the part of your brain that feels pleasure when taking opioids. Because of this you do not feel the rush, high or pain relief that opioids bring. It also decreases the desire to take opioids.
Naltrexone can be taken by mouth once a day or every other day, has few side effects and is not addicting. It is part of a complete treatment program including counseling or psychotherapy, lifestyle changes and social support.
Side effects: nausea and vomiting, stomach pain, headache, dizziness, sadness, nervousness, sleepiness, diarrhea or constipation
Some people have had trouble staying on Naltrexone because of its side effects. But in 2010 an injectable, long-acting form of naltrexone (called Vivitrol®) was approved by the FDA for treating opioid addiction. The effects of Vivitrol® last for weeks, making it a good choice for people who cannot easily access healthcare or who have a hard time taking their medications regularly.

Medication-benefit studies have shown that, if taken as intended, naltrexone does increase the chance of sobriety and decreases risk of overdose.
In this study, patients receiving Vivitrol with psychosocial support after detox had a higher number weeks without using opioids. Vivitrol significantly reduced opioid craving and helped patients stay in treatment longer. Syed 2013
In one review of studies, naltrexone decreased opioid use in people that continued to take the medication. Contingency management, a type of behavioral therapy that rewards people for positive behavior, is a promising method of increasing continued medication use. Johansson B.A. 2006
A six-month study of 250 patients found that 90% of those who received a monthly injection of naltrexone (called Vivitrol) stayed off opioids, compared with 35% of those who took a placebo. Krupitsky E 2011

New Medication Approaches
Recent approaches to heroin and opioid addiction include new medications, combinations of medications, and new ways to take them.
Comparing Naltrexone and Suboxone
The National Institute on Drug Abuse compared two medications to prevent relapse. Suboxone (a combination of buprenorphine and naloxone) was given daily as a film put under the tongue. Naltrexone (Vivitrol) was given as a monthly injection. To take Vivitrol you must have first fully detoxed, but some people have a hard time doing that. This makes Suboxone easier to use.
The study showed that if you can’t use Vivitrol because you couldn’t complete detox you can now start treatment with Suboxone instead - and get the same good results. Suboxone is also much less expensive than Vivitrol, which costs $1,000 per injection.
Implantable Buprenorphine (Probuphine)
In May 2016 the FDA approved the use of Probuphine, a form of buprenorphine that is implanted in the arm. It provides a constant, low-level dose of buprenorphine for six months in patients who are already stable on low-to-moderate doses of the pill or film placed under the tongue. Because the medication is implanted under the skin, you don’t have to remember to take it or visit a clinic every day. In a study of Probuphine, 63% of patients showed no opioid use during the six months of treatment.
Monthly Sublocade Injection
Sublocade is a once-a-month injection of buprenorphine approved by the FDA in 2017. Buprenorphine reduces opioid withdrawal symptoms and the desire to use opioids. In order to have a Sublocade injection you must have been on a stable dose of buprenorphine for at least seven days.
Sublocade was studied in 850 adults with opioid addiction. Patients taking the Sublocade injection had more drug-free weeks compared to those who took a fake pill that has no actual effect (called a placebo). The most common side effects were constipation, nausea, vomiting, headache, drowsiness and injection-site pain.
Reversing an Opioid Overdose
Naloxone quickly restores normal breathing when a person is overdosing on heroin or prescription opioids. Many states allow you to get naloxone from a pharmacist without bringing in a prescription from a doctor. This was done to help family, friends, and other potential bystanders of overdose save lives.
It is available as a prefilled auto-injection device (EVZIO) or as a prepackaged nasal spray (NARCAN Nasal Spray). Visit NIDA’s Naloxone Resources webpage to learn more.
