Buprenorphine Transdermal Patch
(byoo pre nor' feen)
AUDIENCE: Family Practice, Psychiatry, Pain Management, Nursing, Endocrinology
ISSUE: FDA is warning about several safety issues with the entire class of opioid pain medicines. See the http://www.fda.gov/Drugs/DrugSafety/ucm489676.htm for a complete listing. These safety risks are potentially harmful interactions with numerous other medications, problems with the adrenal glands, and decreased sex hormone levels. We are requiring changes to the labels of all opioid drugs to warn about these risks.
BACKGROUND: Opioids are powerful prescription medicines that can help manage pain when other treatments and medicines are not able to provide enough pain relief (see List of Opioid Medicines in the http://www.fda.gov/Drugs/DrugSafety/ucm489676.htm ). However, opioids also carry serious risks, including of misuse and abuse, addiction, overdose, and death.
Prescription opioids are divided into two main categories – immediate-release (IR) products, usually intended for use every 4 to 6 hours; and extended release/long acting (ER/LA) products, intended to be taken once or twice a day, depending on the individual product and patient.
See the http://www.fda.gov/Drugs/DrugSafety/ucm489676.htm for additional information, including a listing of opioids, serotonergic medicines, and a data summary.
Health care professionals should discontinue opioid treatment and/or use of the other medicine if serotonin syndrome is suspected.
Health care professionals should perform diagnostic testing if adrenal insufficiency is suspected. If diagnosed, treat with corticosteroids and wean the patient off of the opioid, if appropriate. If the opioid can be discontinued, follow-up assessment of adrenal function should be performed to determine if treatment with corticosteroids can be discontinued.
Decreased sex hormone levels:
Health care professionals should conduct laboratory evaluation in patients presenting with such signs or symptoms.

Buprenorphine patches can be habit-forming. Do not apply more patches, apply the patches more often, or use the patches in a different way than prescribed by your doctor. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol; uses or has overused prescription medications; uses or has ever used street drugs; or has or has ever had depression or another mental illness. There is a greater risk that you will overuse buprenorphine patches if you have or have ever had any of these conditions.
Buprenorphine patches may cause serious or life-threatening breathing problems, especially during the first 72 hours of your treatment and any time that your dose is increased. Your doctor will monitor you carefully during your treatment. Tell your doctor if you have or have ever had breathing difficulties, asthma, chronic obstructive pulmonary disease (COPD; a group of diseases that affect the lungs and airways), or other lung disease. Your doctor may tell you not to use buprenorphine patches. Tell your doctor and pharmacist if you are taking atazanavir (Reyataz); benzodiazepines such as such as alprazolam (Xanax), chlordiazepoxide (Librium), clonazepam (Klonopin), diazepam (Diastat, Valium), estazolam, flurazepam, lorazepam (Ativan), oxazepam, temazepam (Restoril), triazolam (Halcion); medications for mental illness and nausea; other medications for pain; muscle relaxants; sedatives; sleeping pills; and tranquilizers. If you have any of the following symptoms, call your doctor immediately: difficulty breathing; extreme drowsiness with slow breathing; heartbeat that is slower than normal; cold clammy skin; difficulty thinking, talking, or walking normally; confusion; extreme tiredness; fainting; or loss of consciousness.
Do not allow anyone else to use your medication. Accidental exposure, especially in children, may result in serious harm or death. Store buprenorphine patches in a safe place so that no one else can use them accidentally or on purpose. Be especially careful to keep buprenorphine patches out of the reach of children. Keep track of how many patches are left so you will know if any are missing.
Tell your doctor if you are pregnant or plan to become pregnant. If you use buprenorphine patches regularly during your pregnancy, your baby may experience life-threatening withdrawal symptoms after birth. Tell your baby's doctor right away if your baby experiences any of the following symptoms: irritability, hyperactivity, abnormal sleep, high-pitched cry, uncontrollable shaking of a part of the body, vomiting, diarrhea, or failure to gain weight.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with buprenorphine patches and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
Talk to your doctor about the risks of using this medication.
WHY is this medicine prescribed?
Buprenorphine patches are used to relieve severe pain in people who are expected to need pain medication around the clock for a long time and who cannot be treated with other medications. It is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.
HOW should this medicine be used?
Transdermal buprenorphine comes as a patch to apply to the skin. The patch is usually applied to the skin once every 7 days. Change your patch at about the same time of day every time you change it. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Apply buprenorphine patches exactly as directed.
Your doctor may start you on a low dose buprenorphine patch and gradually increase your dose, not more often than once every 3 days. If this increase involves the use of two patches, remove your current patch and at the same time, place the two new patches next to each other at a new site. If your doctor tells you to use two patches, you should always change and apply them at the same time. Your doctor may decrease your dose if you experience side effects. Contact your doctor if the dose you are taking does not control your pain. Talk to your doctor about how you are feeling during your treatment with buprenorphine patches.
Buprenorphine skin patches are only for use on the skin. Do not place patches in your mouth or chew or swallow the patches.
Do not stop using buprenorphine patches without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop using buprenorphine patches you may have symptoms of withdrawal. Call your doctor if you experience any of these symptoms of withdrawal: restlessness, teary eyes, runny nose, yawning, sweating, chills, hair standing on end, muscle aches, large pupils (black circles in the center of the eyes), irritability, diarrhea, nausea, vomiting, anxiety, pain in the joints, weakness, fast heartbeat, or rapid breathing.
Do not use a buprenorphine patch that is cut, damaged, or changed in any way. If you use cut or damaged patches, you may receive most or all of the medication at once, instead of slowly over 7 days. This may cause serious problems, including overdose and death.
If your buprenorphine patch is exposed to extreme heat, it may release too much medication into your body at once. This can cause serious or life-threatening symptoms.Do not expose your patch or the skin around it to direct heat such as heating pads, electric blankets, heat lamps, saunas, hot tubs, and heated water beds. Do not take long, hot baths or sunbathe while you are wearing the patch.
You may bathe or shower while you are wearing a buprenorphine patch. If the patch falls off during these activities, dispose of it properly. Then dry your skin completely and apply a new patch. Leave the new patch in place for 7 days after you apply it.
You can apply a buprenorphine patch to your upper outer arms, upper chest, upper back, or the side of your chest. Choose an area of skin that is flat and hairless. Do not apply the patch to parts of the body that irritated, broken, cut, damaged, or changed in any way. If there is hair on the skin, use scissors to clip the hair as close to the skin as possible. Do not shave the area. Wait at least 3 weeks before applying a new patch to same site.
To apply the patch, follow these steps:
Are there OTHER USES for this medicine?
Buprenorphine should not be used to treat mild or moderate pain, short-term pain, or pain that can be controlled by medication that is taken as needed.
