Uses for buprenorphine/naloxone

Buprenorphine and naloxone sublingual tablet is used to treat opioid (narcotic) dependence or addiction. Buprenorphine and naloxone buccal film, sublingual film, or sublingual tablet is used for induction and maintenance treatment of opioid (narcotic) dependence. It should be used in patients who have already been treated with buprenorphine sublingual tablets.

When a narcotic medicine is used for a long time, it may become habit-forming, causing mental or physical dependence. Physical dependence may lead to withdrawal side effects if the narcotic is stopped suddenly. Severe withdrawal side effects can usually be prevented when a person is switched to buprenorphine and naloxone combination. It acts on the central nervous system (CNS) to help prevent the withdrawal side effects.

Buprenorphine/naloxone is available only with your doctor's prescription.

Before using buprenorphine/naloxone

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For buprenorphine/naloxone, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to buprenorphine/naloxone or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of buprenorphine and naloxone buccal film, sublingual film, or sublingual tablet in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of buprenorphine and naloxone combination in the elderly. However, elderly patients are more likely to have age-related kidney, liver, heart, or lung problems, which may require caution and an adjustment in the dose for patients receiving buprenorphine and naloxone combination.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking buprenorphine/naloxone, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Using buprenorphine/naloxone with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Clonidine
Yohimbine

Interactions with food/tobacco/alcohol

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Using buprenorphine/naloxone with any of the following is usually not recommended, but may be unavoidable in some cases. If used together, your doctor may change the dose or how often you use buprenorphine/naloxone, or give you special instructions about the use of food, alcohol, or tobacco.

Ethanol

Proper use of buprenorphine/naloxone

Take buprenorphine/naloxone exactly as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.

Buprenorphine/naloxone should come with a Medication Guide. Read and follow these instructions carefully. Ask your doctor if you have any questions.

If you are using the buccal film:

Use your tongue to wet the side of your cheek or rinse your mouth with water in the area where you will place the film.
Do not cut or tear the film. Hold the film on a clean, dry finger. If you are using Bunavail®, hold with the text (BN2, BN4, or BN6) facing up.
Place the side of the film against the inside of your cheek. If you are using Bunavail®, place with the text (BN2, BN4, or BN6) against the inside of your cheek.
Press the film and hold it there for 5 seconds.
Leave the film in place until it dissolves. Do not touch, move, chew, or swallow it.
If you must use more than one film, place the second film on the other side of your mouth. Do not place more than 2 buccal films to the inside of one cheek at a time.
Do not eat or drink anything until the film is completely dissolved.

If you are using the sublingual tablet:

Do not cut, crush, chew, or swallow it.
Place the tablet under the tongue until it is dissolved.
If you take 2 or more tablets at a time, place all of the tablets in different places under the tongue at the same time.
If this is uncomfortable, place 2 tablets at a time under the tongue and repeat the process until all the tablets have been taken.
Do not eat or drink anything until the tablets are completely dissolved.

If you are using the sublingual film:

Drink water before taking buprenorphine/naloxone to help moisten your mouth.
Place the film under the tongue until it is dissolved.
If you need to take an additional film, place the new film on the opposite side from the first film.
Do not eat or drink anything until the film is completely dissolved.
Do not cut, chew, swallow, or move the film after placing it under the tongue.

Check with your doctor first before changing dosage forms (eg, films, tablets) or dosage strengths. These forms are very different from each other.

Dosing

The dose of buprenorphine/naloxone will be different for different patients. Follow your doctor's orders or the directions on the label.

Missed dose

If you miss a dose of buprenorphine/naloxone, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

Storage

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Keep out of the reach of children.

Do not keep outdated medicine or medicine no longer needed.

Ask your healthcare professional how you should dispose of any medicine you do not use.

Drop off any unused narcotic medicine at a drug take-back location right away. If you do not have a drug take-back location near you, flush any unused narcotic medicine down the toilet. Check your local drug store and clinics for take-back locations. You can also check the DEA web site for locations. Here is the link to the FDA safe disposal of medicines website: www.fda.gov/drugs/resourcesforyou/consumers/buyingusingmedicinesafely/ensuringsafeuseofmedicine/safedisposalofmedicines/ucm186187.htm

Precautions while using buprenorphine/naloxone

It is very important that your doctor check your progress while you are using buprenorphine/naloxone. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. Blood tests may be needed to check for unwanted effects.

Do not use buprenorphine/naloxone if you have used an MAO inhibitor (MAOI) (eg, isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]) within the past 14 days.

It is against the law and dangerous for anyone else to use your medicine. Keep your unused films or tablets in a safe and secure place. People who are addicted to drugs might want to steal buprenorphine/naloxone.

Buprenorphine/naloxone may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

Using too much of buprenorphine/naloxone may cause an overdose, which can be life-threatening. Symptoms of an overdose include: blurred vision, confusion, difficult or trouble breathing, dizziness, faintness, or lightheadedness when getting up suddenly from a lying position or sitting position, irregular, fast or slow, or shallow breathing, pale or blue lips, fingernails, or skin, pinpoint pupils, sleepiness, sweating, unusual tiredness or weakness. In case of an overdose, call your doctor right away. Your doctor may also give naloxone to treat an overdose.

Buprenorphine/naloxone may cause sleep-related breathing problems (eg, sleep apnea, sleep-related hypoxemia). Your doctor may decrease your dose if you have sleep apnea (stop breathing for short periods during sleep) while using buprenorphine/naloxone.

Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are using buprenorphine/naloxone. Serious unwanted effects can occur if certain medicines are given together with buprenorphine and naloxone combination.

Buprenorphine/naloxone will add to the effects of alcohol and other CNS depressants. CNS depressants are medicines that slow down the nervous system, which may cause drowsiness or make you less alert. Some examples of CNS depressants are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicine, other prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. This effect may last for a few days after you stop using buprenorphine/naloxone. Check with your doctor before taking any of the medicines listed above while you are using buprenorphine/naloxone.

Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve the dizziness or lightheadedness.

Buprenorphine/naloxone may make you dizzy, drowsy, or lightheaded. Do not drive or do anything else that could be dangerous until you know how buprenorphine/naloxone affects you.

Using buprenorphine/naloxone while you are pregnant may cause neonatal opioid withdrawal syndrome in your newborn baby. Tell your doctor right away if your baby has an abnormal sleep pattern, diarrhea, a high-pitched cry, irritability, shakiness or tremors, weight loss, vomiting, or fails to gain weight.

Buprenorphine/naloxone may cause adrenal insufficiency. Check with your doctor right away if you have darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.

Buprenorphine/naloxone may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, hives, itching, hoarseness, trouble with breathing or swallowing, or any swelling of your hands, face, or mouth while you are using buprenorphine/naloxone.

Do not suddenly stop using it without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help reduce the possibility of withdrawal symptoms, including anxiety, fever, nausea, runny nose, stomach cramps, sweating, tremors, or trouble with sleeping.

Check with your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.

Using too much of buprenorphine/naloxone may cause infertility (unable to have children). Talk with your doctor before using buprenorphine/naloxone if you plan to have children.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
