Drug class: Narcotic analgesics
What is Belbuca?
Belbuca buccal films contain buprenorphine , an opioid medication. An opioid is sometimes called a narcotic .
Belbuca buccal films are for around-the-clock treatment of moderate to severe chronic pain that is not controlled by other medicines.
Belbuca is not for use on an as-needed basis for occasional pain.
The Belbuca buccal film is placed between the gum and cheek where it adheres to the moist buccal mucosa to deliver the medicine as the film dissolves.
Belbuca can slow or stop your breathing, and may be habit-forming. MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using Belbuca without a prescription.
Using Belbuca during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Fatal side effects can occur if you use Belbuca with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before using this medicine
You should not use Belbuca if you are allergic to buprenorphine, or if you have:
- severe asthma or trouble breathing, or a blockage in your stomach or intestines.
To make sure Belbuca is safe for you, tell your doctor if you have ever had:
- tooth problems, including a history of cavities;
- breathing problems, sleep apnea;
- kidney or liver disease (especially hepatitis B or C);

If you use Belbuca while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.
Buprenorphine can pass into breast milk and may harm a nursing baby. You should not breastfeed while you are using Belbuca.
Belbuca is not approved for use by anyone younger than 18 years old.
How should I use Belbuca?
Use Belbuca exactly as prescribed by your doctor. Follow all directions on your prescription label. Buprenorphine can slow or stop your breathing. Never use Belbuca in larger amounts, or for longer than prescribed. Tell your doctor if Belbuca seems to stop working as well in relieving your pain.
Buprenorphine may be habit-forming, even at regular doses. Never share Belbuca with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using Belbuca without a prescription. Selling or giving away Belbuca is against the law.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Place the Belbuca film against the inside of your cheek and hold it in place for 5 seconds. Once in place, the film will dissolve completely in about 30 minutes. Rinse your mouth with water after the medicine dissolves. Wait one hour after the film dissolves to brush your teeth to prevent damage to the teeth and gums. Do not chew the Belbuca film or swallow it whole.
Do not eat or drink anything until the Belbuca film has completely dissolved in your mouth.
You should receive regular dental checkups while using Belbuca.
While using Belbuca, you may need frequent blood tests to check your liver function.
If you need surgery , tell the surgeon ahead of time that you are using Belbuca.
Do not stop using Belbuca suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using buprenorphine.
Store at room temperature away from moisture and heat. Keep Belbuca in a place where a child cannot get to it. Keep track of your medicine. Buprenorphine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
Do not keep leftover opioid medication. Just one dose can cause death in someone using Belbuca accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, remove any unused films from the foil pack and flush the films down the toilet. Throw the empty foil pack into the trash.
