Quick Answer: Suboxone side effects in women commonly include nausea, constipation, headaches, sweating, and sleep disturbances. Some women also experience concerns about menstrual changes, sexual health, or long-term medication use, although these effects can be influenced by previous opioid exposure and other health factors.
Comprehensive Addiction Treatment Designed for Women
Starting Suboxone can bring relief from opioid cravings and withdrawal, but it may also introduce physical changes you weren’t expecting. You might feel nauseated, struggle with constipation, or notice that your sleep or menstrual cycle seems different.
Suboxone contains buprenorphine and naloxone and is used to treat opioid use disorder. Buprenorphine helps reduce cravings and withdrawal symptoms, while naloxone is included to discourage certain forms of misuse. The side effects discussed here generally apply to buprenorphine-naloxone products, including dissolvable films and tablets.
What Symptoms Are Common When Starting Suboxone?
Most Suboxone side effects in women appear early, including digestive discomfort, headaches, sweating, and changes in sleep or alertness. Many ease as your body adjusts to treatment, while a few may require ongoing attention.
Common side effects include:
- Nausea and vomiting: Stomach discomfort that may be more noticeable when you first start treatment.
- Constipation: Slower bowel movements that can continue even after other symptoms improve.
- Headaches and sweating: Head discomfort or increased perspiration during the day or night.
- Drowsiness and dizziness: Feeling unusually tired, lightheaded, or less alert.
- Sleep disturbances: Difficulty falling asleep, staying asleep, or feeling rested.
- Mouth irritation: Numbness, redness, or soreness where you place a dissolvable film or tablet.
Is It a Suboxone Side Effect or Opioid Withdrawal?
Suboxone side effects and opioid withdrawal can feel similar, especially during the first days of treatment. Nausea, sweating, and sleep problems can occur with either, but when symptoms begin and how quickly they develop can offer important clues.
Suboxone Side Effects
Nausea, headaches, constipation, dizziness, or drowsiness may appear after starting Suboxone treatment. Some of these medication-related side effects improve as your body adjusts.
Opioid Withdrawal
Sweating, chills, body aches, diarrhea, and restlessness can occur as other opioids leave your system or when withdrawal isn’t adequately controlled.
Precipitated Withdrawal
Precipitated withdrawal is a sudden worsening of opioid withdrawal symptoms after taking buprenorphine. Starting Suboxone too early can rapidly intensify symptoms, including vomiting, diarrhea, chills, body aches, and severe restlessness. This can be especially relevant when transitioning from fentanyl or methadone.
These symptoms can overlap, so timing alone cannot confirm what’s happening. If you feel significantly worse after taking Suboxone, contact your treatment provider promptly. They can assess your symptoms and help you manage treatment safely.
Can Suboxone Affect Your Menstrual Cycle?
The link between Suboxone and menstrual cycle changes is complicated because hormonal shifts often begin long before a woman starts treatment. Some women notice missed periods, irregular bleeding, or changes in sexual desire during opioid recovery, but these symptoms aren’t necessarily caused by Suboxone itself.
There is an important distinction between buprenorphine and some other opioids. A 2024 Endocrine Society scientific statement found that buprenorphine appears to have milder effects on the hormonal system than certain full opioid agonists. This suggests that women receiving Suboxone may experience different hormonal effects from those associated with some prescription painkillers or other opioids, although research specifically focused on menstruation during Suboxone treatment remains limited.
If your periods remain irregular, stop unexpectedly, or become unusually heavy, a healthcare professional can help evaluate possible causes.
Is Suboxone Safe During Pregnancy or Breastfeeding?
Buprenorphine is an established treatment for opioid use disorder during pregnancy, and staying on effective treatment usually protects both mother and baby. Stopping without medical guidance raises the risk of returning to opioid use. Some babies may have neonatal opioid withdrawal after birth, which healthcare teams can monitor and treat.
Older guidance favored Subutex, a buprenorphine-only formulation, over Suboxone, but recent research shows similar or better outcomes with the combination, and both are now accepted options. Your obstetric and addiction care teams can help you choose.
Breastfeeding is often supported for women who are stable on treatment. Since buprenorphine passes into breast milk, let your baby’s provider know and watch for unusual sleepiness, feeding difficulties, or breathing problems.
What Are the Long-Term Side Effects of Suboxone?
The long-term side effects of Suboxone may include ongoing constipation, fatigue, and dental problems linked to formulations that dissolve in the mouth. Less common concerns include liver problems and adrenal insufficiency, when the body doesn’t make enough of the hormones that help regulate stress and other functions.
Some women take Suboxone for months, others for years, and for some treatment continues indefinitely. There’s no universal point when staying on medication becomes the wrong choice.
Your body can become physically dependent on buprenorphine during prescribed treatment, so stopping suddenly may cause withdrawal. That isn’t the same as compulsive opioid use, and it doesn’t mean your recovery has failed. Stopping treatment can also raise the risk of relapse and overdose, especially once your tolerance to other opioids has dropped.
The right plan depends on how well Suboxone controls cravings, whether side effects are manageable, and what keeps you stable. If you’re exploring other options, our guides to naltrexone and methadone offer more context, though any switch should happen with medical guidance.
Can Suboxone Cause Dental Problems?
Yes. Suboxone films and tablets that dissolve in the mouth have been linked to cavities, tooth decay, oral infections, and even tooth loss, sometimes in people with no prior history of dental problems.
The FDA recommends several precautions to help protect your teeth while taking buprenorphine:
- Let the medication dissolve completely under your tongue or against the inside of your cheek, as prescribed.
- Rinse your mouth with water. Take a large sip, gently swish it around your teeth and gums, and swallow.
- Wait at least one hour before brushing to help protect your teeth.
- Keep up with dental appointments and let your dentist know you’re taking buprenorphine.
When Are Suboxone Side Effects Dangerous?
Most Suboxone side effects in women are manageable, but certain symptoms can signal a serious reaction or medication interaction. Breathing problems are especially concerning when buprenorphine is combined with alcohol, benzodiazepines, other opioids, or medications that cause sedation.
Seek medical attention for warning signs such as:
- Slow or difficult breathing: A possible sign of dangerous respiratory depression.
- Extreme drowsiness or unresponsiveness: Difficulty staying awake or responding normally.
- Yellowing skin or eyes: Possible signs of liver injury, particularly with dark urine or persistent abdominal discomfort.
- Severe weakness, dizziness, or persistent vomiting: Symptoms that may indicate adrenal insufficiency or another medical problem.
- Swelling of the face, lips, or throat: May indicate a severe allergic reaction.
Call 911 immediately for suspected overdose, breathing difficulties, unresponsiveness, or a severe allergic reaction. If an opioid overdose is suspected, administer emergency naloxone when available while waiting for help. The naloxone included in Suboxone does not replace emergency overdose reversal medication.
Alcohol and sedating medications can increase Suboxone side effects in women and can also elevate the risk of serious complications. However, women already taking prescribed benzodiazepines should not abruptly discontinue them or assume they must stop Suboxone. A clinician can review the combination, manage the risks, and maintain access to appropriate treatment.
How Can Fullbrook Support Women During Opioid Recovery?
Suboxone can quiet cravings and withdrawal, but Suboxone side effects in women are rarely the whole story of recovery. Anxiety, depression, difficult relationships, and past experiences of trauma can continue to affect how you feel, even when the physical symptoms of opioid withdrawal are under control.
Opioids can become a way to cope for some women with experiences that were painful or difficult to process. Understanding the connection between trauma and addiction can help make sense of those patterns without judgment.
The Fullbrook Center’s women-only approach brings together treatment for co-occurring mental health and substance use conditions and trauma-focused addiction therapy. We provide a supportive setting where women can work through emotional difficulties, develop coping skills, and build greater stability in recovery.
If you’re currently taking Suboxone, medication continuity and your individual medical needs should be discussed before entering a new treatment setting. Our admissions team can help you explore whether Fullbrook is an appropriate fit and what questions need to be addressed with your prescribing clinician.
FAQs About Suboxone Side Effects in Women
Does Suboxone cause weight gain in women?
Weight changes can occur during Suboxone treatment, but weight gain isn’t a well-established direct effect of the medication. Changes in appetite, nutrition, physical activity, and overall health during recovery may also influence weight. Unexpected changes are worth discussing with your clinician.
Can you take Suboxone with antidepressants like Zoloft or Prozac?
Some women take Suboxone alongside antidepressants for depression or anxiety, but the combination requires medical review. Certain antidepressants, including Zoloft and Prozac, may interact with buprenorphine and rarely contribute to serotonin syndrome. Tell your prescriber about new agitation, mood changes, unusual sweating, tremors, or other concerning symptoms. Seek emergency care for high fever, confusion, and muscle rigidity.
Can I get pregnant while taking Suboxone?
Yes, and sometimes more easily than expected. If your periods stopped or became irregular during active opioid use, your cycle and fertility may start to return once you’re stable on treatment. If you’re not planning a pregnancy, it’s worth talking about birth control with your clinician early on.
What if I need surgery or a c-section while on Suboxone?
Let your surgical or obstetric team know as early as possible. Many women continue buprenorphine through surgery or delivery, and your care teams can plan pain relief together so you stay comfortable without disrupting your recovery.
Will Suboxone show up on a drug test?
Standard opioid screens often don’t detect buprenorphine, so it usually takes a specific test to identify it. If you’re being tested for work, court, or a treatment program, let them know you’re taking a prescribed medication so they interpret the results correctly.
