What is Suboxone?

Suboxone (buprenorphine and naloxone) film is used for opioid dependence to reduce opioid cravings and withdrawal symptoms.

Buprenorphine is a partial opioid agonist that helps to reduce dependency, and naloxone blocks the effects of opioid medication, including pain relief or feelings of well-being that can lead to opioid abuse.

Suboxone sublingual films are used as a single daily dose.

Films should be placed under the tongue (sublingual administration) or inside the left or right cheek (buccal administration). Film should be allowed to completely dissolve.

Suboxone should be used as part of a complete treatment plan that includes counseling and psychosocial support.

Suboxone is not for use as a pain medication.

How should I take Suboxone?

Use Suboxone exactly as prescribed by your doctor. Follow the directions on your prescription label and read all medication guides. Never use Suboxone in larger amounts or for longer than prescribed. Tell your doctor if you feel an increased urge to use more of this medicine.

Before taking a Suboxone sublingual film, drink water to moisten your mouth. This helps the film dissolve more easily. Place one film on the inside of your right or left cheek. If your doctor tells you to take 2 films at a time, place the other film on the inside of the opposite cheek. Keep the films in place until they have completely dissolved. If your doctor tells you to take a third film, place it on the inside of your right or left cheek after the first 2 films have dissolved.

While the medicine is dissolving, do not chew or swallow it because the medicine will not work as well. Talking while the medicine is dissolving can also affect how well it is absorbed.

Suboxone sublingual tablets should be placed under the tongue until they dissolve.

Never share Suboxone with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medicine in a place where others cannot get to it. Selling or giving away Suboxone is against the law.

Rinse your mouth with water after the Suboxone tablet dissolves. Wait one hour after the medicine dissolves to brush your teeth to prevent damage to the teeth and gums. You should receive regular dental checkups while using Suboxone.

If you switch between medicines containing buprenorphine, you may not use the same dose for each one. Follow all directions carefully.

Do not stop using Suboxone suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.

You will need frequent blood tests to check your liver function.

All your medical care providers should know that you are being treated for opioid addiction, and that you take Suboxone. Make sure your family members know how to provide this information in case they need to speak for you during an emergency.

Never crush or break a Suboxone sublingual tablet to inhale the powder or mix it into a liquid to inject the drug into your vein. This practice has resulted in death.

Store Suboxone at room temperature, away from moisture and heat. Store the films in the foil pouch. Discard an empty pouch in a place children and pets cannot get to.

Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.

Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, remove any unused films from the foil pack and flush the films down the toilet. Throw the empty foil pack into the trash.

Warnings

Suboxone can cause serious and life-threatening breathing problems, especially if you take or use certain other medicines or drugs.

Ask your healthcare provider about medicines like naloxone or nalmefene that can be used in an emergency to reverse opioid overdose, including accidental use of Suboxone sublingual film by a child. If naloxone or nalmefene is given, you must call 911 or get emergency medical help right away to treat an overdose or accidental use of an opioid.

Suboxone may cause serious and life-threatening breathing problems. Get emergency help right away if you:

  • feel faint
  • feel dizzy
  • are confused
  • feel sleepy or uncoordinated
  • have blurred vision
  • have slurred speech
  • are breathing slower than normal
  • cannot think well or clearly

Do not take Suboxone with certain medicines. Taking Suboxone with other opioid medicines, benzodiazepines, gabapentinoids (gabapentin or pregabalin), alcohol, or other central nervous system depressants (including street drugs) can cause severe drowsiness, decreased awareness, breathing problems, coma, and death.

Do not inject (“shoot-up”) this medicine. Injecting Suboxone may cause life-threatening infections and other serious health problems. Injecting Suboxone may cause sudden, serious withdrawal symptoms such as pain, cramps, vomiting, diarrhea, anxiety, sleep problems, and cravings.

Do not switch from Suboxone sublingual film to other medicines that contain buprenorphine without talking with your healthcare provider. The amount of buprenorphine in a dose of Suboxone sublingual film is not the same as in other medicines that contain buprenorphine. Your healthcare provider will prescribe a starting dose of Suboxone sublingual film that may be different than other buprenorphine containing medicines you may have been taking.

Do not stop taking this medicine suddenly. You could become sick and have withdrawal symptoms because your body has become used to the medicine (physical dependence). Physical dependence is not the same as drug addiction.

In an emergency, have family members tell emergency department staff that you are physically dependent on an opioid and are being treated with this medicine.

Never give anyone else your Suboxone sublingual film. They could die from taking it. Selling or giving away Suboxone is against the law.

Store this medicine securely, out of sight and reach of children, and in a location not accessible by others, including visitors to the home.

Before taking this medicine

You should not use Suboxone if you are allergic to buprenorphine or naloxone (Narcan).

To make sure Suboxone is safe for you, tell your doctor if you have ever had:

  • tooth problems, including a history of cavities;
  • breathing problems, sleep apnea;
  • enlarged prostate, urination problems;
  • liver or kidney disease;
  • abnormal curvature of the spine that affects breathing;
  • problems with your gallbladder, adrenal gland, or thyroid;
  • a head injury, brain tumor, or seizures; or
  • alcoholism, drug addiction, or mental health problems.

If you use Suboxone while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on opioids may need medical treatment for several weeks.

Tell your healthcare provider if you are breastfeeding or plan to breastfeed. Suboxone can pass into your breast milk and harm your baby. Talk to your healthcare provider about the best way to feed your baby if you take this medicine. Monitor your baby for increased drowsiness and breathing problems if you breastfeed during treatment with Suboxone.

Suboxone side effects

Get emergency medical help if you have signs of an allergic reaction to Suboxone: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Suboxone can slow or stop your breathing, and death may occur. A person caring for you should give naloxone and/or seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.

Call your doctor at once or seek emergency medical attention if you have:

  • any problems with your teeth or gums;
  • weak or shallow breathing, breathing that stops during sleep;
  • a light-headed feeling, like you might pass out;
  • confusion, loss of coordination, extreme weakness;
  • blurred vision, slurred speech;
  • liver problems - upper stomach pain, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
  • high levels of serotonin in the body - agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, diarrhea;
  • low cortisol levels - nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness; or
  • opioid withdrawal symptoms - shivering, goose bumps, increased sweating, feeling hot or cold, runny nose, watery eyes, diarrhea, muscle pain.

Serious breathing problems may be more likely in older adults and those who are debilitated or have wasting syndrome or chronic breathing disorders.

Common Suboxone side effects may include:

  • dizziness, drowsiness, blurred vision, feeling drunk, trouble concentrating;
  • withdrawal symptoms;
  • tongue pain, redness or numbness inside your mouth;
  • nausea, vomiting, constipation;
  • headache, back pain;

Dosing information

Usual Adult Dose for Opiate Dependence - Induction:

INDUCTION: For those Dependent on Heroin or Other Short-acting Opioid Products:-INITIAL DOSES should begin when objective signs of moderate opioid withdrawal appear and not less than 6 hours after the patient last used opioids to avoid precipitating an opioid withdrawal syndrome:Suboxone Sublingual Film:Day 1: up to 8 mg/2 mg sublingually; administer as an initial dose of 2 mg/0.5 mg or 4 mg/1 mg with titration in 2 or 4 mg increments of buprenorphine at approximately 2-hour intervalsDay 2: 16 mg/4 mg sublingually as a single doseComments:-Patients dependent on heroin or other short-acting opioid products may be inducted with combination buprenorphine/naloxone or buprenorphine monotherapy; to avoid precipitating withdrawal during induction, initiation should occur when clear signs of withdrawal are evident, preferably when moderate objective signs of opioid withdrawal appear, and no sooner than 6 hours after last use of heroin or other short-acting opioid.-Suboxone sublingual tablets are not indicated for induction therapy; Suboxone sublingual film for sublingual or buccal use should only be administered sublingually for induction to minimize exposure to naloxone.-For patient's dependent on methadone or long-acting opioid products, buprenorphine monotherapy should be used during the induction phase as naloxone may be absorbed in small amounts and could precipitate or prolong withdrawal during induction.-Maintenance treatment begins on day 3.Use: For the treatment of opioid dependence as part of a complete treatment plan to include counseling and psychosocial support.

Usual Adult Dose for Opiate Dependence - Maintenance:

MAINTENANCE Treatment:-Doses of buprenorphine/naloxone should be adjusted to a level that holds the patient in treatment and suppresses opioid withdrawal signs and symptoms; doses should be titrated to clinical effectiveness as rapidly as possible as gradual titration may lead to higher drop-out rates.SUBOXONE Sublingual Film and Sublingual Tablets:-Progressively adjust in increments/decrements of 2 mg/0.5 mg or 4 mg/1 mg to a level that holds the patient in treatment and suppresses opioid withdrawal signs and symptoms-Recommended target dose: 16 mg/4 mg sublingually (film, tablet) or buccally (film) once a day; dose range 4 mg/1 mg to 24 mg/6 mg-Maximum dose: 24 mg/6 mg per dayComments:-Following induction, maintenance therapy is provided to hold a patient in treatment and suppress opioid withdrawal signs and symptoms; there is no maximum recommended duration for maintenance treatment and some patients may require treatment indefinitely.-There are multiple buprenorphine/naloxone products available for maintenance treatment; these products are not bioequivalent and dose adjustments may be necessary when switching products; e.g., Zubsolv 4.2 mg/0.7 mg buccal film provides equivalent buprenorphine exposure as Suboxone 8 mg/2 mg sublingual tablet.Use: For the treatment of opioid dependence as part of a complete treatment plan to include counseling and psychosocial support.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An opioid overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include severe drowsiness, pinpoint pupils, slow breathing, or no breathing.

Keep an overdose rescue medicine on hand

Talk to your doctor about overdose rescue medicine: Patients and caregivers should learn about medicines that can reverse an opioid overdose, such as naloxone or nalmefene.Keep overdose rescue medicine available: It is important to have access to one of these medicines, especially if you have a higher risk of overdose. This includes people who take other medicines that can cause drowsiness, have a history of opioid use disorder, or have had an opioid overdose before. It is also important if there are children or others in the home who could accidentally use the medicine.Pain treatment should still be considered: Having risk factors for overdose does not mean pain should go untreated. Your doctor can help manage your pain while also taking steps to reduce risk.Know how to get it: Ask your doctor or pharmacist about ways to get an overdose rescue medicine. It may be available by prescription, over the counter, or through a community program.These medicines are not all the same: Overdose rescue medicines can differ in how they are given, how strong they are, who can use them, and how long they last. Your doctor or pharmacist should help you choose the right one and explain how to use it.

Do not drink alcohol or take prescription or over-the-counter medicines that contain alcohol. Dangerous side effects, loss of consciousness, or death could occur.

Avoid driving or operating machinery until you know how this medicine will affect you. Dizziness or severe drowsiness can cause falls, accidents, or severe injuries.

What other drugs will affect Suboxone?

You may have breathing problems or withdrawal symptoms if you start or stop taking certain other medicines. Tell your doctor if you also use an antibiotic, antifungal medication, heart or blood pressure medication, seizure medication, or medicine to treat HIV or hepatitis C.

Opioid medication can interact with many other drugs and cause dangerous side effects or death. Be sure your doctor knows if you also use:

  • cold or allergy medicines, bronchodilator asthma/COPD medication, or a diuretic ("water pill");
  • medicines for motion sickness, irritable bowel syndrome, or overactive bladder;
  • other opioids - opioid pain medicine or prescription cough medicine;
  • a sedative like Valium - diazepam, alprazolam, lorazepam, Xanax, Klonopin, Ativan, and others;
  • drugs that make you sleepy or slow your breathing - a sleeping pill, muscle relaxer, medicine to treat mood disorders or mental illness; or
  • drugs that affect serotonin levels in your body - a stimulant, or medicine for depression, Parkinson's disease, migraine headaches, serious infections, or nausea and vomiting.

This list is not complete. Other drugs may interact with buprenorphine and naloxone, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here.

Common questions about Suboxone

How long does Suboxone stay in your system?

Does Suboxone show up on a drug test?
Suboxone will only show up on a drug test if the panel specifically tests for buprenorphine or its metabolites, or for naloxone. Suboxone will not cause false positives for other opioids. Continue reading
How long does Suboxone withdrawal last?
Withdrawal symptoms typically last for approximately one month, although this may vary depending on the duration of use, the dosage of Suboxone, alcohol use, and presence of medical conditions including other mental health disorders. Physical symptoms (such as nausea, vomiting, headaches) of withdrawal commonly begin within 24 hours after the last dose and last for approximately 10 days. These are generally worse in the first 72 hours. Continue reading
What happens if you take opiates on Suboxone?
If you use opiates while on Suboxone (a combination of buprenorphine and naloxone), the strong effects or “high” of the opiates will be dulled or blocked. Continue reading
How long should you wait before taking Suboxone?
You typically have to wait 12-24 hours after last using short acting opioids before you start taking Suboxone as a treatment for opioid use disorder. The exact length of time depends on the type of opioid used. Continue reading
Does Suboxone help with pain?
Suboxone (buprenorphine and naloxone) can help relieve pain for some people, but it is not approved by the U.S. Food and Drug Administration (FDA) to treat pain. It is approved only to treat opioid use disorder (opioid addiction). Doctors sometimes prescribe Suboxone off-label for pain, mainly in people who also have opioid use disorder. On its own, it is usually not the best choice for pain. Continue reading
How long does it take for Suboxone to start working?
Suboxone starts to work quickly—about 20 to 60 minutes after you take the first dose. The medication should reach peak effect around 100 minutes (1 hour and 40 minutes) after you take the first dose. Dosages may be increased until they effectively reduce withdrawal symptoms. Most people feel much better at the end of the first day. Continue reading
Subutex vs Suboxone: What's the difference between them?
Both Subutex and Suboxone contain buprenorphine, a medication that can help people beat opioid addiction by minimizing withdrawal symptoms and easing cravings. Both Subutex and Suboxone are taken once a day and can be either given by a healthcare professional or taken home for at-home use. But there are differences between them. Continue reading
