Opioid Use After Surgery

Key takeaway

CDC says opioids have a role after invasive surgery with moderate to severe pain, and that postoperative opioid use is linked with a higher chance of long-term use, from under 1 percent to 13 percent in the studies it reviewed. Prescribed use is not the same as opioid use disorder. Do not stop the medicine on your own.

You came home with a bottle, the pain is still real, and you are afraid the prescription already means you have a problem. Severe pain after an invasive operation is one of the situations where CDC says an opioid can have an important role. Acute pain, in the 2022 CDC guideline, lasts less than a month and is often caused by injury, trauma, or a medical treatment such as surgery. The same guideline says opioids are not the first choice for many common acute problems, including minor surgery that usually causes only mild pain, such as a simple dental extraction. The distinction is the clinician's. Which pill, how many, and for how many days stay with that prescriber.

Needing pain medicine after surgery is not, by itself, opioid use disorder.

If breathing has slowed, you cannot wake someone, or lips are blue, call 911. For a mental health crisis, call or text 988.

What the guideline says about the prescription

CDC's recommendation for acute pain is that clinicians should maximize nonopioid care, both medicines such as acetaminophen or an NSAID and steps such as ice, heat, elevation, rest, immobilization, or exercise, as appropriate for the condition. They should consider an opioid only if the benefits are expected to outweigh the risks, and they should discuss those benefits and risks before prescribing.

When an opioid is warranted, CDC says clinicians should use an immediate-release opioid, at the lowest effective dose, and for no longer than the expected duration of pain severe enough to require opioids. Extended-release and long-acting opioids are not for acute pain. CDC also says many patients do not use all of the opioids prescribed after surgery, and that unused pills are a potential source of misuse and diversion. Do not keep a leftover bottle for the next injury. Do not share it.

The guideline is written for clinicians treating adults in outpatient settings. It does not apply to pain from sickle cell disease or cancer, or to palliative or end-of-life care. It does apply when someone is discharged from a hospital and still needs pain care. Recommendations are voluntary. CDC says they should not be applied as inflexible rules.

Doses stay with the prescriber. A milligram that is right for one operation can be wrong for another, and CDC's own examples are instructions to prescribers, not a chart for patients. If the pain is not controlled, call the surgeon or the prescriber. Do not add alcohol, a benzodiazepine, or someone else's pills to close the gap. CDC says clinicians should use particular caution when opioids and benzodiazepines are prescribed together.

Long-term use is a risk, not a verdict

CDC reviewed observational studies and reported that opioid use for postoperative pain was associated with a higher likelihood of long-term opioid use. Across those studies, the share of adults with new long-term opioid use after a short postoperative course ranged from under 1 percent to 13 percent. Higher dosage and a longer initial exposure were linked with higher odds of still using opioids later. Those figures describe study groups. They do not tell you your own chance, and they do not mean that everyone who fills a surgery prescription will still be taking it next year.

CDC also says that if opioids are continued for a month or more, prescribing for acute pain can quietly become long-term therapy just because the prescription was refilled without a new decision. Continuation at that point should be intentional: a discussion that benefits are likely to outweigh risks, inside a broader pain plan. The longer problem is the chronic pain guide. It is not a second surgery instruction.

Patients who already take long-term opioids and then have major surgery are a different case. CDC says any extra opioid should last only as long as the severe new pain requires it, and the dose should return to the person's baseline as soon as possible. That return is a clinician's taper. It is not a decision for the night you get home.

Dependence is not the same as opioid use disorder

NIDA separates three ideas that get collapsed into the word "addicted."

Dependence is the body adapting to a drug. Stop suddenly, and withdrawal can follow. NIDA says dependence often comes with addiction, but they are not equivalent. Withdrawal from opioids can include restlessness, muscle and bone pain, insomnia, diarrhea, vomiting, cold flashes, and involuntary leg movements. Those symptoms are a reason to call the prescriber. They are not proof of a use disorder, and they are not a reason to white-knuckle a cutoff.

Tolerance means the same dose does less. After surgery, a clinician has to sort tolerance from pain that is not yet controlled. NIDA says that distinction is difficult, which is why the prescriber should look at function, not only at the request for more medicine.

Addiction, in NIDA's wording, is compulsive seeking and use despite negative consequences. NIDA also says it is possible to develop a substance use disorder even when opioid medicine is taken as prescribed, and that the risk is higher when the medicine is misused. Misuse includes taking more than prescribed or taking it in a way other than prescribed. A single large dose can slow or stop breathing. Alcohol or sedatives make that more likely.

NIDA's heroin research report adds a boundary that matters after an operation: tolerance or withdrawal that occurs during medically supervised treatment is specifically excluded from an opioid use disorder diagnosis. Feeling shaky between prescribed doses is not, by itself, the disorder. The diagnosis and the medicines used to treat it are the prescription opioid guide. Do not use a webpage to label yourself.

NIDA says that when short-term medical use is properly managed, a few days of opioid pain medicine, for example after oral surgery, rarely leads to opioid use disorder. Regular use, several times a day for several weeks or longer, can lead to dependence and, in some cases, addiction. "Several weeks" is NIDA's description of a pattern. It is not permission to set your own end date, and it is not a rule that day 15 equals a disorder.

What to do if the use starts to worry you

CDC says that if signs of opioid use disorder are present, clinicians should address those concerns with the patient, offer or arrange medication treatment for people who meet criteria, and still treat the pain with nonopioid options as appropriate. Detoxification by itself, without medications for opioid use disorder, is not recommended, because the risks of returning to drug use, overdose, and overdose death go up. The medicines FDA has approved for opioid use disorder are buprenorphine, methadone, and naltrexone. They are described, without doses, on the medication guide. Methadone for this disorder comes from a certified opioid treatment program. Do not start any of them from a leftover surgery bottle.

Do not stop a prescribed opioid on your own to see whether you are hooked. CDC tells clinicians not to discontinue opioid therapy abruptly, and not to cut a higher dose rapidly, unless there are signs of a life-threatening problem such as impending overdose. The warning signs CDC gives clinicians include confusion, sedation, and slurred speech. If those are happening now, get emergency help. Do not treat them as a cue for a home taper. If you have been taking opioids around the clock for more than a few days, CDC says clinicians should include a taper when the medicine is stopped, so withdrawal is not left unmanaged. The pace is theirs.

Slowed or stopped breathing is an overdose, including from medicine that was prescribed. That emergency is the naloxone guide. CDC says clinicians should offer naloxone when the patient or someone in the household has overdose risk. Ask for it.

Care for opioid use disorder can be listed on FindTreatment.gov. A referral is for the days after you are medically stable. It does not replace the surgeon or the prescriber.

Call or text (800) 653-9376 if you want help finding care for opioid use that has outlasted the surgery, or if you are unsure what kind of program fits.

Common Questions

Does taking opioids after surgery mean I have an addiction?

No. NIDA says short-term medical use, such as a few days after oral surgery, rarely leads to opioid use disorder when it is managed properly. Dependence, which is the body adapting to the medicine, is not the same as addiction. A clinician diagnoses opioid use disorder.

How often does short-term use after surgery turn into long-term use?

CDC's 2022 guideline says observational studies link opioid use for postoperative pain with a higher likelihood of long-term opioid use. In the studies it reviewed, the share of adults with new long-term use after short-term postoperative opioids ranged from under 1 percent to 13 percent. That is a range across studies, not a personal prediction, and it is not a diagnosis.

Should I stop the pills once the worst pain fades?

Do not stop them on a schedule you found online. CDC tells clinicians not to discontinue opioid therapy abruptly, and not to rapidly cut a higher dose, unless there are signs of a life-threatening problem such as impending overdose. If you have been taking the medicine around the clock, ask the prescriber how to come off it. Call 911 for slowed breathing, confusion you cannot wake from, or blue lips.

When is postsurgical use a reason to ask about opioid use disorder?

CDC says clinicians should address concerns and offer or arrange medication treatment if signs of opioid use disorder are present. NIDA describes addiction as compulsive use despite harmful consequences, separate from needing a short course for pain. Using more than prescribed, craving, or trouble meeting obligations are reasons to call the prescriber. They are not a reason to quit alone to test yourself.

Are leftover surgery pills safe to save for the next injury?

CDC says opioids prescribed for surgery that go unused are a potential source for misuse and diversion. Do not save them for a later injury, and do not give them to someone else. Ask a pharmacist or the prescriber how to dispose of what you do not need. A later injury needs its own assessment.
