If you’re considering Suboxone for opioid use disorder treatment, understanding potential side effects is an important part of making an informed decision about your care. While Suboxone (buprenorphine/naloxone) is a safe and effective medication when used as prescribed, like all medications, it can cause side effects in some people.
At Porch Light Health, we believe in providing transparent, comprehensive information about all aspects of medication-assisted treatment (MAT). This guide will help you understand what side effects you might experience, how to manage them, and when to contact your healthcare provider.
Suboxone is a prescription medication approved by the U.S. Food and Drug Administration (FDA) that combines two active ingredients: buprenorphine and naloxone. Buprenorphine is a partial opioid agonist that helps reduce cravings and withdrawal symptoms without producing the intense euphoria associated with full opioid agonists like heroin or prescription painkillers. Naloxone is an opioid antagonist included to discourage misuse of the medication.
When taken as prescribed under the tongue (sublingually) or inside the cheek (buccally), Suboxone helps stabilize brain chemistry, allowing you to focus on recovery without the constant cycle of cravings and withdrawal. According to the Substance Abuse and Mental Health Services Administration (SAMHSA), this medication is most effective when combined with counseling and behavioral therapy as part of a comprehensive treatment approach.
Most people who take Suboxone experience few or no side effects, especially after the initial adjustment period. However, some common side effects may occur, particularly when you first start treatment or when your dose is adjusted.
Headaches are one of the most frequently reported side effects of Suboxone, particularly during the first few weeks of treatment. These headaches are typically mild to moderate and often improve as your body adjusts to the medication. Staying well-hydrated, maintaining regular sleep patterns, and managing stress can help reduce headache frequency and intensity.
If headaches persist or become severe, your healthcare provider may adjust your dosage or recommend over-the-counter pain relief options that are safe to use with Suboxone.
Nausea is another common side effect, especially when first starting Suboxone treatment. Some people also experience constipation, stomach pain, or vomiting. Because buprenorphine is an opioid (though a partial agonist), it can slow digestive function similar to other opioid medications.
To minimize digestive side effects:
Many people experience drowsiness, particularly during the first few weeks of Suboxone treatment. This sedative effect usually decreases as your body adjusts to the medication. However, it’s important to avoid driving or operating heavy machinery until you know how Suboxone affects you.
If persistent fatigue interferes with your daily activities, talk to your healthcare provider during your treatment journey about potentially adjusting your dosing schedule or evaluating other factors that might be contributing to tiredness.
While some people experience drowsiness, others report difficulty sleeping or insomnia. This paradoxical effect can be frustrating, but several strategies can help improve sleep quality during Suboxone treatment:
Excessive sweating, particularly night sweats, is a common side effect that many people experience during Suboxone treatment. While uncomfortable, this side effect typically improves over time. Wearing breathable, moisture-wicking fabrics, keeping your environment cool, and staying hydrated can help manage this symptom.
Because Suboxone dissolves under the tongue or inside the cheek, some people experience mouth-related side effects including:
Rotating the placement of the Suboxone film or tablet, practicing good oral hygiene, and staying hydrated can help minimize these effects. If you develop persistent mouth sores or severe irritation, contact your healthcare provider.
Some people report experiencing muscle aches, back pain, or general body discomfort during Suboxone treatment. These symptoms are usually mild and can often be managed with gentle stretching, regular movement, and over-the-counter pain relievers approved by your healthcare provider.
While rare, some side effects require immediate medical attention. It’s important to be aware of these potential complications so you can seek help if needed.
Suboxone has a “ceiling effect” for respiratory depression, meaning that beyond a certain dose, increasing the amount doesn’t significantly increase this risk. However, respiratory depression can still occur, particularly when:
Warning signs of respiratory depression include:
If you or someone you know experiences these symptoms, call 911 immediately. The National Institute on Drug Abuse (NIDA) emphasizes the importance of seeking immediate medical attention for respiratory symptoms.
Though uncommon, allergic reactions to Suboxone can occur. Seek immediate medical attention if you experience:
Suboxone is processed by the liver, and in rare cases, it can cause liver damage, particularly in people with existing liver conditions like Hepatitis C or those who take other medications that affect the liver. Your healthcare provider will typically monitor your liver function through blood tests, especially when starting treatment.
According to the National Library of Medicine, signs of liver problems include:
Long-term use of Suboxone may affect hormone levels, potentially leading to:
If you experience these symptoms, talk to your healthcare provider about hormone testing and potential treatment options. These effects don’t mean you should stop taking Suboxone—hormone issues can often be addressed while continuing your medication-assisted treatment.
One of the most uncomfortable side effects can occur if Suboxone is taken too soon after using full opioid agonists. Because buprenorphine is a partial agonist, it can displace full agonist opioids from receptors in the brain, causing sudden and severe withdrawal symptoms known as precipitated withdrawal.
This is why it’s crucial to follow your healthcare provider’s instructions carefully about when to take your first Suboxone dose. Typically, you need to be in mild to moderate withdrawal from other opioids before starting Suboxone. Your treatment team will guide you through this process during your intake to ensure a safe transition.
Understanding when side effects are most likely to occur can help you prepare and know what’s normal versus what requires medical attention.
During the initial period after starting Suboxone, you may experience:
These early side effects are typically your body’s initial response to the medication. Stay in close contact with your healthcare provider during this time.
As your body begins adjusting to Suboxone:
By the end of the first month:
After the initial adjustment period:
While you can’t always prevent side effects, several strategies can help minimize their impact on your daily life.
Taking Suboxone correctly is essential for both effectiveness and reducing side effects:
Simple lifestyle adjustments can significantly reduce side effects:
Open communication with your treatment providers is crucial. Be honest about:
At Porch Light Health, our treatment approach includes regular check-ins to monitor your progress and address any concerns. We believe that managing side effects effectively is an important part of successful long-term recovery.
Suboxone can interact with other medications and substances, potentially increasing side effect risk or affecting how well the medication works.
Benzodiazepines: Combining Suboxone with benzodiazepines (like Xanax, Valium, or Ativan) significantly increases the risk of respiratory depression, sedation, and overdose. The FDA has issued warnings about this dangerous combination. If you take benzodiazepines for anxiety or other conditions, talk to your healthcare provider about safer alternatives or careful monitoring.
Alcohol: Drinking alcohol while taking Suboxone increases the risk of dangerous side effects, including severe drowsiness, respiratory depression, and overdose. Avoid alcohol entirely during Suboxone treatment. If you’re struggling with alcohol use disorder, our team can help you address both conditions through integrated treatment.
Other Opioids: Taking other opioid medications or using illicit opioids like heroin or fentanyl while on Suboxone can lead to precipitated withdrawal or increased overdose risk. Always inform your healthcare providers that you’re taking Suboxone before they prescribe pain medications.
CNS Depressants: Other medications that slow the central nervous system (certain muscle relaxants, sleep medications, or antihistamines) may increase drowsiness and respiratory depression risk when combined with Suboxone.
Some medications can affect how your body processes Suboxone:
Always provide your healthcare provider with a complete list of all medications, supplements, and herbal products you take.
Understanding how Suboxone’s side effect profile compares to other medication-assisted treatment options can help you make an informed decision about your care.
Methadone is a full opioid agonist, while Suboxone contains a partial agonist. Key differences include:
At Porch Light Health, we offer both Suboxone and methadone treatment options through our clinics in Denver and Lakewood, allowing us to tailor medication-assisted treatment to your specific needs and circumstances.
Naltrexone is an opioid antagonist that works differently than Suboxone:
Sublocade and Brixadi are injectable forms of buprenorphine (the primary active ingredient in Suboxone):
Porch Light Health offers multiple MAT options, including Suboxone, naltrexone, Sublocade, and Brixadi, and we’ve recently expanded to include methadone treatment. Your treatment team will help you find the medication that best fits your recovery goals and lifestyle.
Certain groups may experience side effects differently or require special monitoring during Suboxone treatment.
Suboxone is generally considered safe during pregnancy and is often the preferred MAT option for pregnant individuals with opioid use disorder. According to the American College of Obstetricians and Gynecologists (ACOG), continuing MAT during pregnancy is significantly safer than returning to opioid use. However:
Older adults may be more sensitive to Suboxone’s effects:
Because Suboxone is processed by the liver, people with liver conditions require:
If you have co-occurring mental health conditions:
Porch Light Health specializes in treating co-occurring disorders through dual diagnosis treatment, providing comprehensive care that addresses both substance use and mental health needs.
While many side effects improve on their own, certain situations require prompt medical attention. Contact your healthcare provider if you experience:

Several common myths about Suboxone can create unnecessary fear or prevent people from seeking effective treatment.
Myth: “Suboxone just replaces one addiction with another.”
Reality: Suboxone is a prescribed medication used to treat a medical condition. When taken as prescribed, it doesn’t produce euphoria or impairment. According to SAMHSA, it allows your brain chemistry to stabilize, enabling you to engage in recovery work and rebuild your life.
Myth: “Suboxone side effects are worse than withdrawal.”
Reality: While Suboxone can cause side effects, they’re typically mild and temporary. Opioid use disorder withdrawal, on the other hand, can be extremely uncomfortable and often leads people back to opioid use. Most people find Suboxone side effects far more manageable than withdrawal or active addiction.
Myth: “You’ll be on Suboxone forever and never be able to stop.”
Reality: Many people successfully taper off Suboxone when they’re ready. However, for some people, long-term maintenance is the most effective approach. There’s no shame in taking medication long-term to manage a chronic condition—just as people take medication for diabetes or high blood pressure indefinitely.
Myth: “Natural or rapid detox is better than Suboxone.”
Reality: Rapid detox methods carry significant risks and have high relapse rates. Medication-assisted treatment like Suboxone, combined with counseling and support, has the highest success rates for long-term recovery from opioid use disorder.
Myth: “Side effects mean the medication isn’t working or isn’t right for you.”
Reality: Side effects don’t indicate whether Suboxone is effective. Many people experience side effects during the adjustment period but find Suboxone highly effective for managing cravings and supporting recovery. If side effects are problematic, dose adjustments or switching to a different formulation (like Sublocade or Brixadi) may help.
Medication-assisted treatment is most effective when combined with counseling and behavioral therapy. This integrated approach can also help manage side effects:
At Porch Light Health, we believe in treating the whole person, not just prescribing medication. Our comprehensive approach combines effective medication-assisted treatment with behavioral therapy and ongoing support to give you the best chance at lasting recovery.
Experiencing side effects doesn’t mean you should discontinue Suboxone or that medication-assisted treatment isn’t right for you. Most side effects are temporary, manageable, and far outweighed by the benefits of effective treatment for opioid use disorder.
Thousands of people successfully use Suboxone to break free from opioid addiction, rebuild their lives, and achieve long-term recovery. With proper medical supervision, open communication with your treatment team, and a comprehensive approach to recovery, you can minimize side effects while maximizing the effectiveness of your treatment.
