Buprenorphine side effects can include headache, nausea, vomiting, constipation, sweating, and insomnia. How long these effects last varies from person to person. If you have severe breathing problems or cannot wake up, call 911 or go to the nearest emergency room now. For suicidal thoughts, call or text 988.
This guide covers US buprenorphine products for opioid use disorder, like Suboxone. It offers general info, not personal medical advice. We are a treatment directory, not a provider. Talk with your prescriber about your specific needs.
What This Guide Covers: Suboxone and Other Buprenorphine Products
This guide focuses on buprenorphine side effects for oral Suboxone products used in buprenorphine treatment for opioid use disorder. It does not cover every medicine that contains buprenorphine.
Buprenorphine is a medication used to treat opioid use disorder.[1] However, the specific side effects you experience depend on the product form and how it is used. Do not apply side effect lists from pain products to Suboxone, or vice versa.
| Product/Form | General Labeled Use | Why Side Effects Differ |
|---|---|---|
| Transdermal buprenorphine patch | Pain management | Designed for chronic pain, not addiction treatment. Side effects may vary by dose and duration. |
If you have questions about beginning treatment, see our guide on starting Suboxone safely. This article focuses on human treatment in the United States and does not address veterinary use or international formulations.
Buprenorphine Side Effects Common With Suboxone
Suboxone has two active ingredients: buprenorphine and naloxone.[2] The FDA label lists effects often seen with this medicine. These include headache, nausea, vomiting, constipation, sweating, insomnia, withdrawal symptoms, pain, and swelling in the hands or feet.[2]

These numbers come from product labels and studies. They do not predict your personal risk. Your body reacts differently than others.
| Possible Effect | What It Might Feel Like |
|---|---|
| Headache | A dull or throbbing pain in your head |
| Nausea or Vomiting | Feeling sick to your stomach or throwing up |
| Constipation | Infrequent or hard bowel movements |
| Sweating | Perspiring a lot, even when cool |
| Insomnia | Trouble falling asleep or staying asleep |
| Withdrawal Symptoms | Flu-like aches, anxiety, or restlessness |
| Pain | Discomfort in muscles or joints |
| Peripheral Edema | Swelling in hands, ankles, or feet |
This list shows possible effects from the FDA label.[2] Not everyone gets these side effects. Talk to your prescriber if you notice new symptoms. They can help you manage them safely.
How Long Do Buprenorphine Side Effects Last?
There is no single timeline for how long buprenorphine side effects last. Every person’s body reacts differently, and the length of time you feel a symptom depends on many factors. Because of this, doctors cannot promise that effects will fade by a specific date or week.
It is also important to know that some side effects can look like withdrawal. For example, nausea, sweating, and restlessness can happen as medication effects, but they are also common signs of opioid withdrawal.[3] This overlap makes it hard to guess the cause on your own.
Notice a symptom
Pay attention to what you are feeling and when it started.
Record details
Write down the symptom, how it changes throughout the day, and any recent changes in your health or other medications.
Contact your prescriber
Reach out if the symptom gets worse, sticks around, or makes it hard to do your daily activities.
Follow their assessment
Your clinician will review your notes to determine the best next step for your care.
This process is not a promise that side effects will resolve on a set schedule. It is a way to gather clear information so you and your provider can make safe decisions together. If you are unsure whether a feeling is a side effect or something else, ask your doctor rather than waiting to see if it goes away.
Which Symptoms Need Urgent Medical Attention?
Most buprenorphine side effects are manageable. But a few need quick action. Knowing the difference helps you stay safe.
| Symptom Pattern | Next Step |
|---|---|
| Worsening or persistent non-emergency effects | Contact your prescriber to discuss your symptoms and adjust your plan if needed. |
| New tooth pain, cavities, or other dental changes | Contact your dentist and your prescriber promptly. |
If you are unsure if it is an overdose, seek emergency care. It is safer to check. You can learn more about recognizing overdose signs in our guide on recognizing overdose signs.
Sleepiness, Sedation, and Immediate Safety
You may feel sleepy or dizzy. These are possible buprenorphine side effects.[5] They can make it hard to stay alert. Be careful when driving or using heavy machines. Wait until you know how your body reacts.
Know the difference between normal tiredness and danger. If you are hard to wake up, call 911 now. If your breathing is slow or shallow, go to the nearest emergency room right away. Do not wait for symptoms to get worse.
Mixing Suboxone with alcohol or benzodiazepines raises risks. It can cause deep sedation and breathing problems.[6] This mix can lead to coma or death.[6] Do not stop or change any prescribed medicine on your own. Always talk with your doctor first.
If sleepiness lasts for days, call your prescriber. They can help adjust your plan safely.
Physical Dependence Is Not the Same as Addiction
Many people worry about getting dependent on their medicine. It helps to know that physical dependence and addiction are different. This knowledge can lower your fear. It also helps you talk with your care team.
| Feature | Physical Dependence | Opioid Use Disorder |
|---|---|---|
| What it is | Your body gets used to the medicine. | A condition where you lose control over use. |
| How it happens | It can happen when you take medicine as prescribed. | It involves using despite harm to your life. |
| Meaning | It is a normal body reaction, not addiction.[7] | It is a medical issue that needs care. |
Your body can get used to an opioid medicine over time. This can happen even if you take it exactly as told.[8] This does not mean you are addicted. The FDA says physical dependence is not the same as drug addiction.[7]
But be careful. If your body is used to the medicine, stopping suddenly can cause withdrawal.[9] Do not stop or change your dose on your own. Talk to your prescriber if you have worries. They can help you stay safe. You can also learn more about these terms in our guide on medication-assisted treatment explained.
What to Do if You Notice Side Effects
Most side effects are manageable. But you should not ignore them. Talk with your prescriber or pharmacist about any new symptoms.
If you have seizures, severe confusion, or hallucinations, call 911 or go to the emergency room now. Also go if you have a high fever, a racing heart during withdrawal, or signs of an overdose. Call or text 988 for suicidal thoughts.
What to Tell the Prescriber
Your ticks are saved on this device only.
If you have questions about using the film form of buprenorphine, check your prescription label. Read the official product instructions too. Your pharmacist can also walk you through the steps safely.

What Should I Do Next?
This self-check is for information only and isn't a diagnosis.
Naloxone can temporarily reverse an opioid overdose.[11] You still need emergency medical care after a suspected overdose.[11] Staying in buprenorphine treatment and recovery support helps your care team respond quickly if issues arise.

Frequently Asked Questions
What are the common side effects of Suboxone?
Common side effects include headache, nausea, vomiting, constipation, sweating, and insomnia. These reactions often fade as your body adjusts. If a symptom feels unusual or lasts a long time, talk with your clinician. They can help check if the medicine is the cause.
How long do buprenorphine side effects last?
There is no single timeline that fits everyone. Some effects go away quickly. Others take longer to settle. This guide does not promise a specific number of days. If symptoms are getting worse or hurting your daily life, call your prescriber. Do not wait for an arbitrary deadline.
Does Suboxone make you nod off?
Sleepiness can happen with buprenorphine treatment. If drowsiness is ongoing or gets in the way of your day, ask your prescriber for advice. Do not drive or use heavy equipment if you feel sleepy or impaired. If someone is hard to wake up or has slow, shallow breathing, get emergency help now.
Can buprenorphine medicines dissolved in the mouth cause dental problems?
Yes, some buprenorphine medicines dissolved in the mouth can cause dental issues like cavities and gum disease. This warning does not apply to every form of buprenorphine. The FDA says to rinse your mouth with water after the medicine dissolves.[12] Swallow the rinse and wait at least one hour before brushing teeth.[12] Tell your dentist about the medicine so they can help prevent problems.
Is buprenorphine addictive?
Physical dependence is different from opioid use disorder. Having a tolerance does not mean you have an addiction problem. The US Drug Enforcement Administration classifies buprenorphine as a Schedule III controlled substance.[13] This status reflects its regulatory standing and potential for abuse. It is not a diagnosis of addiction for people using it as prescribed.
