Notice:

FDA Drug Safety Communication:

[Posted 4/13/2023]

  • As part of its ongoing efforts to address the nation's opioid crisis, FDA is requiring several updates to the prescribing information of opioid pain medicines. The changes are being made to provide additional guidance for safe use of these drugs while also recognizing the important benefits when used appropriately. The changes apply to both immediate-release (IR) and extended-release/long-acting preparations (ER/LA).
  • Updates to the IR opioids state that these drugs should not be used for an extended period unless the pain remains severe enough to require an opioid pain medicine and alternative treatment options are insufficient, and that many acute pain conditions treated in the outpatient setting require no more than a few days of an opioid pain medicine.
  • Updates to the ER/LA opioids recommend that these drugs be reserved for severe and persistent pain requiring an extended period of treatment with a daily opioid pain medicine and for which alternative treatment options are inadequate.
  • A new warning is being added about opioid-induced hyperalgesia (OIH) for both IR and ER/LA opioid pain medicines. This includes information describing the symptoms that differentiate OIH from opioid tolerance and withdrawal.
  • Information in the boxed warning for all IR and ER/LA opioid pain medicines will be updated and reordered to elevate the importance of warnings concerning life-threatening respiratory depression, and risks associated with using opioid pain medicines in conjunction with benzodiazepines or other medicines that depress the central nervous system (CNS).
  • Other changes will also be required in various other sections of the prescribing information to educate clinicians, patients, and caregivers about the risks of these drugs.

AUDIENCE: Dentistry, Anesthesiology, Patient, Health Professional, Pharmacy

ISSUE: The FDA is warning that dental problems have been reported with medicines containing buprenorphine that are dissolved in the mouth. The dental problems, including tooth decay, cavities, oral infections, and loss of teeth, can be serious and have been reported even in patients with no history of dental issues. Despite these risks, buprenorphine is an important treatment option for opioid use disorder (OUD) and pain, and the benefits of these medicines clearly outweigh the risks. The FDA is requiring a new warning about the risk of dental problems be added to the prescribing information and the patient Medication Guide (https://bit.ly/3FYER1g for all buprenorphine-containing medicines dissolved in the mouth.

BACKGROUND: Buprenorphine was approved in 2002 as a tablet to be administered under the tongue to treat OUD. In 2015, buprenorphine was approved as a film to be placed inside the cheek to treat pain. The buprenorphine medicines that are associated with dental problems are tablets and films dissolved under the tongue or placed against the inside of the cheek.

RECOMMENDATIONS:

    Patients
  • Continue taking your buprenorphine medicine as prescribed; do not suddenly stop taking it without first talking to your health care professional as it could lead to serious consequences. Suddenly stopping these medicines could cause you to become sick with withdrawal symptoms because your body has become used to the buprenorphine medicine, or to relapse to opioid misuse that could result in overdose and death.
  • Patients using buprenorphine medicines dissolved in the mouth should take extra steps to help lessen the risk of serious dental problems. After the medicine is completely dissolved, take a large sip of water, swish it gently around your teeth and gums, and swallow. You should wait at least 1 hour before brushing your teeth to avoid damage to your teeth and give your mouth a chance to return to its natural state.
  • Inform your health care professional if you have a history of tooth problems, including cavities. Schedule a dentist visit soon after starting this medicine and inform your dentist that you are taking buprenorphine, and schedule regular dental checkups while taking this medicine. Your dentist can customize a tooth decay prevention plan for you. Notify both your health care professional and your dentist immediately if you experience any problems with your teeth or gums.
    Health Professionals
  • Health care professionals should be aware the benefits of buprenorphine medicines clearly outweigh the risks and are an important tool to treat OUD. When combined with counseling and other behavioral therapies, this comprehensive https://www.samhsa.gov/medication-assisted-treatment approach is often the most effective way for treating OUD, and can help sustain recovery and prevent or reduce opioid overdose.
  • Ask patients about their oral health history prior to prescribing treatment with a transmucosal buprenorphine medicine. These serious dental problems have been reported even in patients with no history of dental issues, so refer them to a dentist as soon as possible after starting transmucosal buprenorphine. Counsel patients about the potential for dental problems and the importance of taking extra steps after the medicine has completely dissolved, including to gently rinse their teeth and gums with water and then swallow. Patients should be advised to wait at least 1 hour before brushing their teeth. Dentists treating someone taking a transmucosal buprenorphine product should perform a baseline dental evaluation and caries risk assessment, establish a dental caries preventive plan, and encourage regular dental checkups.

Throw away the foil packaging in the trash. Do not flush buprenorphine (Belbuca) down the toilet in the foil packages or cartons.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

In case of emergency/overdose

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

While using buprenorphine (Belbuca), you should talk to your doctor about having a rescue medication called naloxone readily available (e.g., home, office). Naloxone is used to reverse the life-threatening effects of an overdose. It works by blocking the effects of opiates to relieve dangerous symptoms caused by high levels of opiates in the blood. Your doctor may also prescribe you naloxone if you are living in a household where there are small children or someone who has abused street or prescription drugs. You should make sure that you and your family members, caregivers, or the people who spend time with you know how to recognize an overdose, how to use naloxone, and what to do until emergency medical help arrives. Your doctor or pharmacist will show you and your family members how to use the medication. Ask your pharmacist for the instructions or visit the manufacturer's website to get the instructions. If symptoms of an overdose occur, a friend or family member should give the first dose of naloxone, call 911 immediately, and stay with you and watch you closely until emergency medical help arrives. Your symptoms may return within a few minutes after you receive naloxone. If your symptoms return, the person should give you another dose of naloxone. Additional doses may be given every 2 to 3 minutes, if symptoms return before medical help arrives.

Symptoms of overdose may include the following:

  • slow or shallow breathing or difficulty breathing
  • extreme sleepiness or drowsiness
  • unable to respond or wake up
  • slow heartbeat
  • cold, clammy skin
  • muscle weakness
  • narrowing or widening of the pupils (black circles in the center of the eye)
  • unusual snoring

What other information should I know?

Keep all appointments with your doctor and laboratory. Your doctor may order certain lab tests to check your body's response to buprenorphine.

Before having any laboratory test (especially those that involve methylene blue), tell your doctor and the laboratory personnel that you are using buprenorphine.

Do not let anyone else use your medication. Buprenorphine (Belbuca) is a controlled substance. Prescriptions may be refilled only a limited number of times; ask your pharmacist if you have any questions.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
