Quick answer: Suboxone contains buprenorphine, a long-acting partial opioid agonist, plus naloxone. The FDA label says stopping it abruptly or tapering too fast causes opioid withdrawal that is typically milder than withdrawal from full opioids such as heroin or oxycodone, and may be delayed in onset. Common symptoms are anxiety, aches, sweating, runny nose, yawning, insomnia, stomach cramps and diarrhea. Buprenorphine’s half-life is 24 to 42 hours, so symptoms can take longer to appear than with short-acting opioids. Do not stop on your own. The label recommends a gradual taper planned with your prescriber, and there is no maximum length of time someone can safely stay on treatment.
Call 911 or go to an emergency room if you or someone with you:
- Is very drowsy, cannot be woken, or is breathing slowly or not at all (give naloxone if you have it)
- Cannot keep fluids down because of vomiting or diarrhea, or shows signs of dehydration such as dizziness or very little urine
- Has chest pain, fainting, or confusion
- Is thinking about suicide: call or text 988 (Suicide & Crisis Lifeline)
After withdrawal, tolerance drops. Using the amount you used before can cause an overdose.
What is Suboxone, and why does stopping it cause withdrawal?
Suboxone is a sublingual film that combines buprenorphine and naloxone. It is one of the FDA-approved medications for opioid use disorder (OUD), used to stop withdrawal and cravings so people can stabilize and recover.
Buprenorphine is a partial opioid agonist. It binds tightly to the brain’s mu-opioid receptors and activates them less than full opioids like heroin, fentanyl or oxycodone do. Taken every day, it still produces physical dependence of the opioid type. That is expected with long-term treatment and is not the same thing as addiction. When the medication is stopped suddenly or reduced too quickly, the body has to readjust, and that readjustment is withdrawal.
The naloxone in Suboxone is there for misuse. Taken under the tongue as directed, it has little effect. The label explains that if the film is dissolved and injected, the naloxone is likely to cause withdrawal in someone dependent on opioids.
How Suboxone withdrawal compares with other opioids
The FDA label describes buprenorphine withdrawal as typically milder than withdrawal from full agonists and notes that it may be delayed in onset. A big reason is how slowly the drug leaves the body.
| Opioid | What the sources say about withdrawal |
|---|---|
| Heroin | Symptoms usually begin within about 12 hours of the last use (MedlinePlus). |
| Methadone | Symptoms usually begin within about 30 hours of the last dose (MedlinePlus). |
| Buprenorphine (Suboxone) | Mean elimination half-life of 24 to 42 hours. Withdrawal is typically milder than with full agonists and may be delayed in onset (FDA label). |
A general rule in pharmacology is that a drug is mostly cleared after about five half-lives. For buprenorphine that works out to roughly five to nine days, which is why Suboxone withdrawal tends to build gradually rather than hit within hours.
Suboxone withdrawal symptoms
Suboxone withdrawal is opioid withdrawal, so the symptoms are the same kind. MedlinePlus groups opioid withdrawal symptoms into early and later stages:
| Stage | Common symptoms |
|---|---|
| Early | Anxiety, agitation, muscle aches, watery eyes, runny nose, sweating, yawning, trouble sleeping |
| Later | Stomach cramps, diarrhea, nausea, vomiting, dilated pupils, goosebumps |
Cravings are often the hardest part. For someone who was taking Suboxone for opioid use disorder, cravings during or after withdrawal are a warning sign, not a personal failure.
What affects how long and how hard withdrawal is
There is no single Suboxone withdrawal timeline that fits everyone. The label does not give a fixed duration. These factors shape the experience:
- Dose: higher daily doses generally mean more dependence to unwind
- Length of treatment: months or years on the medication versus a short course
- Taper speed: the label links withdrawal to abrupt discontinuation or a rapid taper
- Other substances: alcohol, benzodiazepines or other opioids complicate withdrawal and raise risk
- Physical and mental health: pain conditions, anxiety, depression and poor sleep can all make symptoms feel worse
- Support: a stable home and a plan for what comes next make a real difference
Is Suboxone withdrawal dangerous?
MedlinePlus describes opioid withdrawal as painful but usually not life-threatening. The real dangers are:
- Dehydration: vomiting and diarrhea can cause dehydration and electrolyte problems
- Relapse and overdose: withdrawal lowers tolerance, so a person who returns to opioids can overdose on a much smaller amount than they used before. MedlinePlus notes that most opioid overdose deaths occur in people who have just detoxed. With fentanyl in much of the street supply, this risk is serious.
- Mental health: low mood, anxiety and poor sleep can be intense. If you have thoughts of suicide, call or text 988.
Should you stop Suboxone at all?
This is a decision to make with your prescriber, not alone. The FDA label states that there is no maximum recommended duration of maintenance treatment and that some patients may need treatment indefinitely. It also tells prescribers to warn patients about the potential for relapse after stopping medication-assisted treatment.
Some people do decide to come off Suboxone once they are stable. If that is your goal, the label’s guidance is clear: taper gradually rather than stopping all at once. Your prescriber can set the pace and slow down if symptoms or cravings become too strong. This article does not give a taper schedule, because the right plan depends on your dose, history and health.

When medically supervised detox makes sense
Many people taper with their own prescriber as outpatients. A supervised setting is usually the safer choice if:
- You are using Suboxone that was not prescribed to you, or taking more than prescribed
- You also use fentanyl, heroin, pain pills, alcohol or benzodiazepines
- Previous attempts to stop ended in relapse
- You have depression, anxiety, or thoughts of suicide
- You have significant medical conditions or are pregnant
- Home is not a stable or supportive place to go through withdrawal
In medical detox, physicians manage withdrawal symptoms, monitor hydration and vital signs, and treat sleep, nausea and anxiety. Just as important, a good program plans what happens after detox, including whether continuing or restarting medication is the safer path.

Frequently asked questions
How long does Suboxone withdrawal last?
It varies from person to person, and the FDA label does not give a fixed duration. Buprenorphine has a half-life of 24 to 42 hours, so symptoms tend to start later and build more gradually than with short-acting opioids. Dose, length of treatment and how quickly the medication is reduced all change how long it lasts.
Is Suboxone withdrawal worse than heroin or fentanyl withdrawal?
Usually not. The FDA label says withdrawal from buprenorphine is typically milder than withdrawal from full opioid agonists, and may be delayed in onset. It can still be very uncomfortable, especially after high doses or long-term use.
Can you die from Suboxone withdrawal?
Opioid withdrawal is usually not life-threatening, but severe vomiting and diarrhea can cause dangerous dehydration. The biggest risk is relapse: tolerance drops during withdrawal, so returning to opioids can cause a fatal overdose.
Should I taper off Suboxone or quit cold turkey?
The FDA label recommends a gradual taper rather than stopping abruptly. Work out the plan with your prescriber, who can adjust the pace if withdrawal or cravings become too strong.
Does insurance cover detox from Suboxone or opioids?
Many insurance plans cover medically necessary detox. Coverage depends on your plan. Our admissions team can check your benefits immediately at (844) 798-0516.
