Injection route(Solution)

Use of buprenorphine hydrochloride increases the risk of opioid addiction, abuse, or misuse, which may cause overdose or death. Assess the risk prior to therapy and monitor for signs of addiction, abuse, or misuse during therapy. Serious, life-threatening, or fatal respiratory depression may occur, particularly at treatment initiation and with dose increases. Monitor for signs of respiratory depression during treatment. Prolonged use during pregnancy may result in neonatal opioid withdrawal syndrome, which may be life-threatening if unnoticed and untreated. If prolonged use is required in a pregnant woman, advise the patient of the risk to the fetus. Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for patients with inadequate alternative treatment options. Limit dosages and durations to the minimum required, and follow patients for signs and symptoms of respiratory depression and sedation .

Uses of This Medicine:

Buprenorphine injection is used to relieve moderate to severe pain. It is also used in patients who have received treatment with an oral form of buprenorphine that is placed under the tongue or inside the cheek for 7 days, followed by an adjustment in the dose for at least 7 days.

Buprenorphine belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.

When a narcotic medicine is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.

Buprenorphine injection and Buprenex® are available only with your doctor's prescription. Brixadi™ and Sublocade® injection is available only under a restricted distribution program called Brixadi™ REMS (Risk Evaluation and Mitigation Strategy) Program and Sublocade® REMS Program.

Before Using This Medicine:

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 this medicine, the following should be considered:

Allergies—

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.

Children—

Appropriate studies have not been performed on the relationship of age to the effects of Brixadi™ and Sublocade® injection in the pediatric population. Safety and efficacy have not been established.

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of buprenorphine injection and Buprenex® in children 2 to 12 years of age. However, safety and efficacy have not been established in children younger than 2 years of age.

Older adults—

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of buprenorphine injection in the elderly. However, elderly patients may be more sensitive to the effects of this medicine than younger adults, and 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 injection.

Breast-feeding—

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.

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.

Proper Use of This Medicine:

A nurse or other trained health professional will give you or your child this medicine. This medicine is given as a shot under your skin, into a muscle, or into a vein.

It is very important that you understand the requirements of the Brixadi™ and Sublocade® REMS program, and become familiar with the Brixadi™ and Sublocade® medication guide. Read and follow these instructions carefully. Ask your doctor if you have any questions. Ask your pharmacist for the medication guide if you do not have one.

Your doctor will give you a few doses of this medicine until your condition improves, and then switch you or your child to an oral medicine that works the same way. If you have any concerns about this, talk to your doctor.

Precautions While Using This Medicine:

It is very important that your doctor check the progress of you or your child while receiving this medicine, especially within the first 24 to 72 hours of treatment. This will allow your doctor to see if the medicine is working properly and to decide if you or your child should continue to take it.

Do not use this medicine if you are using or have used an MAO inhibitor (eg, Eldepryl®, Marplan®, Nardil®, or Parnate®) within the past 14 days.

This medicine may be habit-forming. If you or your child feels that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

Using narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you or your child to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.

Symptoms of an overdose include: drowsiness, extreme dizziness or weakness, irregular, fast or slow, or shallow breathing, pale or blue lips, fingernails, or skin, pinpoint pupils, relaxed and calm, slow heartbeat or breathing, seizures, sleepiness, trouble breathing, or cold, clammy skin. Tell your doctor right away if you notice these symptoms. Your doctor may also give naloxone to treat an overdose.

This medicine 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 this medicine.

This medicine will add to the effects of alcohol and other CNS depressants (medicines that can make you drowsy or 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. Check with your doctor before taking any of the other medicines listed above while you or your child is receiving this medicine.

This medicine may make you dizzy, drowsy, confused, or disoriented. Do not drive do anything else that could be dangerous until you know how this medicine affects you.

If you or your child has been receiving this medicine regularly for several days, do not suddenly stop receiving it without first checking with your doctor. You or your child may be directed to slowly reduce the amount you are using before stopping treatment completely to lessen the chance of withdrawal side effects (eg, stomach cramps, fever, runny nose, anxiety, or restlessness).

This medicine may increase your risk for serious injection site reactions. Check with your doctor right away if you have bleeding, blistering, burning, coldness, discoloration of skin, feeling of pressure, hives, infection, inflammation, itching, lumps, numbness, pain, rash, redness, scarring, soreness, stinging, swelling, tenderness, tingling, ulceration, or warmth at the injection site.

Using this medicine while you are pregnant may cause neonatal withdrawal syndrome in your newborn babies. 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.

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. These may be symptoms of adrenal gland problems.

Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you or anyone in your family has ever had a heart rhythm problem such as QT prolongation.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you or your child are receiving this medicine.

Check with your doctor right away if you have dark urine, general tiredness and weakness, light-colored stools, nausea and vomiting, upper right stomach pain, and yellow eyes and skin. These may be symptoms of liver problems.

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 this medicine may cause infertility (unable to have children). Talk with your doctor before using this medicine if you plan to have children.

Make sure any doctor or dentist who treats you knows that you have been using Sublocade® injection within the last 6 months.

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.
