GENERIC NAME: BUPRENORPHINE - SUBLINGUAL (BUE-pre-NOR-feen)
BRAND NAME(S): Subutex
USES: Buprenorphine is used to treat dependence/addiction to narcotics (opioids). Buprenorphine belongs to a class of drugs called mixed narcotic agonist-antagonists. It helps prevent withdrawal symptoms caused by stopping other opiate-type narcotics. It is used as part of a complete treatment program for drug abuse (such as compliance monitoring, counseling, behavioral contract, lifestyle changes).
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using sublingual buprenorphine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Use this medication as directed by your doctor, usually once daily. Place the medication under your tongue for 5 to 10 minutes and let it dissolve completely. If you are prescribed more than one tablet each day, you may place all of the tablets under your tongue at once or place two tablets at a time under your tongue. Do not swallow or chew this medication. It will not work as well.Buprenorphine alone is usually used for the first 2 days after you have stopped all other narcotics. It is usually given in your doctor's office. Your doctor will then switch you to the combination buprenorphine/naloxone medication for maintenance treatment. The combination with naloxone works the same way as buprenorphine alone to prevent withdrawal symptoms. It is combined with naloxone to prevent misuse (injection) of the medication.Buprenorphine works best when the first dose is started after signs of narcotic withdrawal have begun or at least 4 hours after last narcotic use. Buprenorphine can cause withdrawal symptoms if started too soon after your last narcotic use. Follow your doctor's instructions for your treatment plan.The dosage is based on your medical condition and response to treatment. Do not increase your dose, take the medication more frequently, or take it for a longer time than prescribed. Properly stop the medication when so directed.Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each day.This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as restlessness, watering eyes, runny nose, nausea, sweating, muscle aches) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately.Do not inject ("shoot up") buprenorphine. Injecting it is dangerous and may cause severe withdrawal symptoms (see Side Effects section). Consult your doctor or pharmacist for more details.Tell your doctor immediately if you experience any withdrawal reactions.
SIDE EFFECTS: Drowsiness, dizziness, constipation, or headache may occur. If any of these effects persist or worsen, tell your doctor or pharmacist immediately.To prevent constipation, eat a diet adequate in fiber, drink plenty of water, and exercise. Consult your pharmacist for help in selecting a laxative (such as a stimulant type with stool softener).To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Severe (possibly fatal) breathing problems can occur if this medication is abused, injected, or mixed with other depressants (such as alcohol, benzodiazepines including diazepam, other narcotics).Tell your doctor right away if you have any serious side effects, including: mental/mood changes (such as agitation, confusion, hallucinations), stomach/abdominal pain.Get medical help right away if any of these rare but serious side effects occur: fainting, fast/irregular heartbeat, severe dizziness, slow/shallow breathing, unusual drowsiness/difficulty waking up.Although this medication is used to prevent withdrawal reactions, it may rarely cause narcotic withdrawal symptoms, including diarrhea, severe mental/mood changes (such as anxiety, irritability, trouble sleeping), muscle stiffness or shakiness. This is more likely when you first start treatment or if you have been using long-acting narcotics such as methadone. If such symptoms occur, notify your doctor or pharmacist immediately.This drug may rarely cause serious liver disease. Get medical help right away if you have any symptoms of liver damage, including: dark urine, persistent nausea/vomiting, yellowing eyes/skin, severe stomach/abdominal pain.A very serious allergic reaction to this drug is rare.

Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Avoid alcoholic beverages. Alcohol also increases your risk for breathing problems.Buprenorphine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using buprenorphine, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using buprenorphine safely.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Older adults may be more sensitive to the side effects of this drug, especially confusion, dizziness, drowsiness, slow/shallow breathing, and QT prolongation (see above).Before using this medication, women of childbearing age should talk with their doctor(s) about the risks and benefits. Tell your doctor if you are pregnant or if you plan to become pregnant. During pregnancy, this medication should be used only when clearly needed. It may slightly increase the risk of birth defects if used during the first two months of pregnancy. Also, using it for a long time or in high doses near the expected delivery date may harm the unborn baby. To lessen the risk, take the smallest effective dose for the shortest possible time. Tell the doctor right away if you notice any symptoms in your newborn baby such as slow/shallow breathing, irritability, abnormal/persistent crying, vomiting, or diarrhea.This drug passes into breast milk and may rarely have undesirable effects on a nursing infant. Tell the doctor immediately if your baby develops unusual sleepiness, difficulty feeding, or trouble breathing. Consult your doctor before breast-feeding.

Therefore, tell your doctor or pharmacist if you are taking other products such as alcohol, allergy or cough-and-cold products, anti-seizure drugs (such as phenobarbital), medicine for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants, other narcotics (such as hydrocodone, oxycodone), and psychiatric medicines (such as risperidone, amitriptyline, trazodone). Your medications or doses of your medications may need to be changed.Deaths have occurred when buprenorphine has been misused by injecting it ("shooting up"), especially when used in combination with benzodiazepines (such as diazepam) or other depressants such as alcohol or additional narcotics.

Drug addiction is a chronic disease that causes drug-seeking behavior and drug use despite negative consequences to the user and those around him. Though the initial decision to use drugs is voluntary, changes in the brain caused by repeated drug abuse can affect a person's self-control and ability to make the right decisions and increase the urge to take drugs. Drug abuse and addiction are preventable.
