How should I take buprenorphine and naloxone?
Follow all directions on your prescription label. This medicine can slow or stop your breathing. Your doctor may occasionally change your dose. Never use buprenorphine and naloxone in larger amounts, or for longer than prescribed.

Selling or giving away buprenorphine and naloxone 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.
Use dry hands when handling the tablet or film. Drink a glass of water to moisten your mouth. Place the sublingual tablet or sublingual film under the tongue and allow it to dissolve. Place the buccal film in your mouth against the inside of your cheek and allow it to dissolve. Do not chew or cut a tablet or film, and do not swallow it whole.
If you switch between medicines containing buprenorphine, you may not use the same dose for each one. Follow all directions carefully.
Do not stop using buprenorphine and naloxone suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.
You will need frequent blood tests to check your liver function.
Any medical care provider who treats you should know that you are being treated for opioid addiction, and that you are taking buprenorphine and naloxone. Make sure your family members know how to provide this information in case they need to speak for you during an emergency.
Never crush or break a buprenorphine and naloxone pill to inhale the powder or mix it into a liquid to inject the drug into your vein. This practice has resulted in death.

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 this medicine 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.
