How does this medication work? What will it do for me?

Buprenorphine belongs to the class of medications called opioid analgesics (pain relievers). Buprenorphine is only intended to treat persistent severe chronic (long-term) pain, when pain relief is needed around the clock and when other treatment options are no effective in controlling pain. This medication is not used to treat pain on an "as needed" basis.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

What form(s) does this medication come in?

How should I use this medication?

The dose of buprenorphine buccal film varies depending on the individual's pain and tolerance to side effects.

For people who have not been using opioid pain relievers, the recommended starting dose is 75 µg once or twice daily. This dose can then be gradually increased until pain is controlled and side effects are tolerable.

The starting dose for people who are currently taking opioids depends on the current daily dose of opioid.

The maximum daily dose of buprenorphine is 900 µg taken every 12 hours.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Keep the medication in its pouch until you are ready to use a dose. Wet the inside of your cheek, either with your tongue or by rinsing your mouth with water.

Using a clean, dry finger, press a film in place in the inside of the cheek for 5 seconds to ensure the contact of the buccal film and the inside of the cheek is complete. The yellow side of the film should go against the cheek. Leave the film in place until it has dissolved. Do not use the buprenorphine film if it is cut or damaged in any way. Do not chew or swallow the buprenorphine film.

It usually takes less than 30 minutes for the buccal film to dissolve. Avoid eating or drinking until the film is completely dissolved. Eating or drinking before the film has completely dissolved reduces the amount of medication that is absorbed and therefore, decreases the effectiveness of the medication.

It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Accidental exposure to the buprenorphine film may cause death or serious medical problems. Store this medication at room temperature in a safe place, protect it from light and moisture, and keep it out of the reach and sight of children.

Do not dispose of any unneeded medication in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Abdominal (stomach) conditions: Like other narcotic medications, buprenorphine may make the diagnosis of abdominal conditions more difficult or it may worsen these conditions. If you have a history of abdominal problems, such as constipation or slow movement of material through the digestive system, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Abnormal heart rhythms: This medication can cause an abnormal heart rhythm problem called QT prolongation. If you have a history of QT prolongation, slow or irregular heartbeat, irregular heart rhythm, heart failure, heart attack, heart disease, taking other medications known to cause QT prolongation, or a family history of sudden cardiac death at less than 50 years of age, discuss with your doctor how this medication may affect your medical condition, or how your medical condition may affect the dosing and effectiveness of this medication. Your doctor will perform tests at regular intervals to monitor for any changes in your heart rhythm.

Accidental use: When buprenorphine is used by anyone other than the person for whom it was prescribed, the effects of the medication may be fatal. Keep this medication out of sight and reach of children. Avoid removing the medication from its protective pouch until you are ready to use it.

Alcohol and other medications that cause drowsiness: Do not combine buprenorphine with alcohol or other medications (e.g., antidepressants, sleeping pills, anxiety medications) that cause drowsiness since additive drowsiness can occur and cause serious injury or death. Tell your doctor if you are using any of these other medications.

Blood pressure: Buprenorphine can cause decreases in blood pressure, especially when a person rises from a lying or sitting position (orthostatic hypotension). To minimize the feeling of dizziness or lightheadedness upon standing, get up slowly from a lying or sitting position. If you have a condition that increases your risk of low blood pressure (hypotension) such as certain heart conditions, cerebrovascular disease (e.g., strokes), are prone to dehydration, or are being treated with blood pressure medications, discuss with your doctor how this medication may affect your medical condition or medications you are taking and whether any special monitoring is needed.

Dependence and withdrawal: As with other opioid medications, physical dependence can occur when this medication is taken for long periods of time. This is not the same as addiction. Misuse of this medication is not usually a problem when it is used appropriately to treat pain. Consult your doctor if you have any questions.

It is important to tell your doctor if you or a family member have ever been dependent on or misused alcohol, prescription medications, or street drugs.

Drowsiness/reduced alertness: Buprenorphine may impair the mental or physical abilities needed for certain potentially hazardous activities such as driving a car or operating machinery. Avoid driving or operating heavy machinery until you have determined how this medication affects you.

Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.

If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.

Medical conditions: If you have addiction problems, Addison's disease, blood pressure problems, enlarged prostate, problems urinating, mental health problems (e.g., depression or hallucinations), reduced pituitary function, or reduced thyroid function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Mouth Sores: This medication is absorbed into the body more quickly if you have sores in your mouth, possibly resulting in an overdose. If you have mouth irritation or sores, do not use this medication.

Respiratory conditions: This medication affects breathing and may cause respiratory depression. If you experience difficulty breathing, including slow, shallow breathing, seek medical attention immediately. If you have breathing difficulties (e.g., asthma, chronic obstructive pulmonary disease [COPD], sleep apnea), are severely overweight, are taking medications that may affect breathing (e.g., codeine, morphine, oxycodone, anesthetic agents, haloperidol, phenobarbital), or are a senior, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Seizures: Buprenorphine can increase the risk of seizures, particularly if you have a seizure disorder. If you have a history of seizures, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Buprenorphine is not recommended for people with a seizure disorder that is being treated.

Stopping the medication: Stopping this medication suddenly may lead to withdrawal symptoms such as anxiety, sweating, difficulty sleeping, rigors, pain, nausea, tremors, diarrhea, difficulty breathing, goose bumps, or, rarely, hallucinations. If you are thinking of stopping the medication, check with your doctor first. This medication should be stopped gradually as recommended by your doctor.

Pregnancy: Taking this medication during pregnancy can harm the developing baby and cause a withdrawal syndrome in the baby after birth. Buprenorphine should not be used during pregnancy. If you become pregnant while using this medication, contact your doctor immediately.

Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are using buprenorphine buccal film, it may affect your baby. Women taking this medication should not breast-feed.

Children: The safety and effectiveness of using this medication have not been established for children.

Seniors: Seniors are at increased risk of experiencing side effects caused by this medication. Your doctor may recommend lower doses and increase the dose more gradually to avoid unnecessary side effects.
