Quick summary

Opioid use disorder is a chronic, treatable condition affecting more than 6.1 million people aged 12 or older, per the FDA. Buprenorphine, methadone, and naltrexone reduce cravings and lower overdose risk, yet fewer than 1 in 5 people receive them. If someone is unresponsive after an overdose, call 911 and give naloxone.

Opioid use disorder is a chronic, treatable medical condition, and effective medications exist. Buprenorphine, methadone, and naltrexone reduce cravings and withdrawal and lower the risk of a fatal overdose. If someone is unresponsive or not breathing, call 911 and give naloxone immediately.

How common is opioid use disorder?

The FDA estimates that more than 6.1 million people aged 12 or older in the United States have an opioid use disorder. SAMHSA's 2023 National Survey on Drug Use and Health found that 8.9 million people misused opioids in the past year, including 8.6 million who misused prescription pain relievers and 660,000 who used heroin.

Fentanyl, a powerful synthetic opioid, is often mixed into other drugs without the user's knowledge, which makes any non-prescribed pill or powder especially risky.

Medications that treat opioid use disorder

NIDA reports that three FDA-approved medications help people stop or reduce opioid use by easing withdrawal and cravings without producing the intense high of opioid drugs:

  • Methadone is a long-acting opioid medication dispensed through approved opioid treatment programs. It has been used for more than 50 years.
  • Buprenorphine is a partial opioid agonist available as a daily tablet or film and as longer-acting injections or implants.
  • Naltrexone blocks opioid receptors entirely. It does not control withdrawal or cravings, and treatment usually starts only after a person has stopped opioids for 7 to 10 days.

A separate medicine, lofexidine, treats the acute symptoms of opioid withdrawal. NIDA notes that medications for opioid use disorder are safe and effective, including during pregnancy and breastfeeding, yet fewer than 1 in 5 people with the condition receive them.

What opioid withdrawal is like

Withdrawal begins hours after the last dose and can include muscle aches, nausea, sweating, anxiety, and insomnia. It is rarely life-threatening, but it is intensely uncomfortable and a common reason people return to use. Because tolerance drops during abstinence, returning to the same dose can cause a fatal overdose.

Do not go through severe withdrawal alone. Medically supervised withdrawal and medication can make the process safer and more tolerable.

How to respond to an overdose

If you suspect an opioid overdose:

  1. Call 911.
  2. Try to keep the person awake and breathing, and place them on their side if they are unconscious.
  3. Give naloxone if you have it, and stay until help arrives.

Naloxone reverses an opioid overdose and is available as a nasal spray or injection. FDA-approved nasal sprays can now be bought over the counter without a prescription. For a mental health crisis, call or text 988.

Frequently asked questions

What medications treat opioid use disorder?

The FDA has approved three medications: buprenorphine, methadone, and naltrexone. A fourth medicine, lofexidine, helps ease acute opioid withdrawal symptoms.

How do I respond to an opioid overdose?

Call 911, try to keep the person awake and breathing, and give naloxone if you have it. Naloxone is an overdose-reversal medicine available as a nasal spray or injection, and FDA-approved nasal sprays are sold over the counter.

Is opioid withdrawal dangerous?

Opioid withdrawal is very uncomfortable but rarely life-threatening by itself. The greater danger is returning to use after a period of abstinence, which lowers tolerance and raises the risk of a fatal overdose.

How many people have opioid use disorder?

The FDA estimates that more than 6.1 million people aged 12 or older have an opioid use disorder. SAMHSA's 2023 survey found that 8.9 million people misused opioids in the past year.

Can I get medication treatment for opioid use disorder?
