Consumer Medicine Information (CMI)

This leaflet provides important information about using SUBOXONE FILM. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using SUBOXONE FILM.

Where to find information in this leaflet:

1. Why am I using SUBOXONE FILM?

SUBOXONE FILM contains two active ingredients buprenorphine hydrochloride and naloxone hydrochloride dihydrate. Buprenorphine acts as a substitute for opioids and it helps withdrawal from opioids over a period of time. When taken sublingually (under the tongue) or buccally (inside the cheek) as prescribed, naloxone has no effect, as it is very poorly absorbed. However, if SUBOXONE FILM is injected, naloxone will act to block the effects of other opioids like heroin, methadone, morphine, oxycodone or codeine, leading to bad withdrawal symptoms. Therefore, naloxone is included in SUBOXONE FILM to discourage misuse by injection, as it can cause very bad withdrawal symptoms.

SUBOXONE FILM is used as part of a medical, social and psychological treatment program for patients dependent on opioids.

Ask your doctor or healthcare professional if you have any questions about why SUBOXONE FILM has been prescribed for you.

2. What should I know before I use SUBOXONE FILM?

Warnings

SUBOXONE FILM is only for adults and children over the age of 16 years. Your doctor will tell you how much SUBOXONE FILM to take and you should always follow medical advice.

Opioids can cause

• sleep apnoea (stopping breathing from time to time while sleeping) which can lead to low levels of oxygen in the blood. Tell your doctor if you have a history of sleep apnoea or if anyone notices you stop breathing from time to time whilst sleeping.

• a decreased level of hormones in the blood caused by a problem with the adrenal glands. The effects of these hormone changes may include nausea, vomiting, loss of appetite, feeling very tired and weak, feeling dizzy, or low blood pressure.

• an increased level of the hormone ‘prolactin’ and decreased level of sex hormones in the blood. you are allergic to buprenorphine or any of the ingredients listed at the end of this leaflet.

Tell your doctor if you notice any of these symptoms. You may need blood tests, and your doctor may tell you to stop using SUBOXONE FILM.

Do not use SUBOXONE FILM if:

• you are allergic to buprenorphine or to naloxone or to of the ingredients listed at the end of this leaflet.
• you are taking benzodiazepines unless they have been prescribed by your doctor.
• always check the ingredients to make sure you can use this medicine.
• you have serious problems with your liver, or if your doctor detects the development of a serious liver problem during treatment.
• you are under the age of 16 years.
• you have serious breathing problems.
• you are intoxicated due to CNS depressant medicines (e.g. tranquilisers, sedative/hypnotics, narcotic pain killers, anti-anxiety or antipsychotic medicines), alcohol or have delirium tremens (the ‘shakes’ and hallucinations).
• the package is torn, shows signs of tampering or the films do not look quite right.

Check with your doctor if you:

• have any other medical conditions such as asthma or other breathing problems, thyroid problems, prostate problems, problems with excess alcohol use, problems with drowsiness, Adrenal gland problems (e.g. Addison’s disease), Kyphoscoliosis (hunchback disease), low blood pressure, urination problems, kidney problems, liver problems,
• have head injuries or have a condition where you have increased pressure within your head
• have problems related to the biliary tract
• have a history of seizures or if you have severe mental problems or hallucinations (seeing or hearing things that are not really there).
• take any medicines for any other condition.

Some people have died from respiratory failure (inability to breathe) when using benzodiazepines (medicines used to treat anxiety or sleeping problems) at the same time as SUBOXONE FILM.

As SUBOXONE FILM contains naloxone, it is highly likely to produce strong opioid withdrawal symptoms if misused as an injection while you are still experiencing the effects of other opioids.

SUBOXONE FILM can cause withdrawal symptoms (dependence) if you

• take it less than six hours after you use a short acting opioid (such as morphine or heroin) or less than 24 hours after a long-acting opioid (such as morphine or heroin) or less than 24 hours after a long-acting opioid (such as methadone) when taken sublingually or buccally
• stop using the medicine too quickly. Withdrawal symptoms may be delayed in some cases.

SUBOXONE FILM may cause

• fatal respiratory failure in children who accidentally ingest it.
• drowsiness, which may be made worse if you also drink alcohol or take sedatives or anti-anxiety medicines. If you are drowsy, do not drive or operate machinery.
• your blood pressure to drop suddenly, causing you to feel dizzy if you get up too quickly from sitting or lying down.
• withdrawal symptoms if taken while still under the influence of another opioid.

SUBOXONE FILM is not intended for occasional use and should be taken only as prescribed.

Athletes should be aware that this medicine may cause a positive reaction to "anti-doping" tests.

The safety and effectiveness in patients over 65 years of age have not been established.

Your doctor may ask you to have additional blood tests to see if this medication is right for you.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

Use of SUBOXONE FILM or other opioids by the mother during pregnancy may result in withdrawal symptoms in the baby following birth, this is called Neonatal Abstinence Syndrome. Neonatal Abstinence Syndrome is a condition that includes disturbances to a newborn baby's nervous, gastro-intestinal and breathing systems. Not all babies who are exposed to SUBOXONE FILM in this way will have withdrawal symptoms. Talk to your doctor if you become pregnant or plan to become pregnant during treatment with SUBOXONE FILM. Your doctor will help you consider the risks and benefits of continued treatment and plan for monitoring your baby following birth. Due to the long duration of buprenorphine effect, your baby will be monitored for several days at the end of pregnancy for effects on breathing and for withdrawal symptoms.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with SUBOXONE FILM and affect how it works.

In particular, tell your doctor, nurse or pharmacist if you are taking any of the following medicines:

• medicines containing alcohol
• certain medicines for treating HIV/AIDS
• certain medicines for treating fungal and bacterial infections
• strong painkillers
• cough medicines containing opioid-related substances
• certain antidepressants including monoamine oxidase inhibitors
• certain medicines used to treat fits or epilepsy (anti-convulsants)
• sedating antihistamines
• sedatives
• alcohol
• anti-anxiety medicines
• certain medicines for high blood pressure
• antipsychotic medicines
• naltrexone
• other opioid medicines.

Tell your doctor if you are scheduled to have surgery using a general anesthetic.

Alcohol and certain other medicines (as listed above) may increase the sedative effects of buprenorphine which can make driving and operating machinery hazardous.

Some people have died when using sedatives (benzodiazepines) or other depressants, alcohol or other opioids at the same time as SUBOXONE FILM. You should not use benzodiazepines (medicines used to treat anxiety or sleep disorders) whilst you are taking SUBOXONE FILM unless they are prescribed by your doctor.

Do not drink alcohol or take medicines that contain alcohol whilst you are being treated with SUBOXONE FILM.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect SUBOXONE FILM.

• For patients who are still using short acting opioids such as heroin, morphine, oxycodone or codeine: when starting treatment, the dose of SUBOXONE FILM should be taken when the first signs of craving appear or at least 6 hours after your last use of opioid or when the first signs of craving appear.
• For patients receiving methadone: before beginning treatment with SUBOXONE FILM, your doctor will probably reduce your dose of methadone to the minimum daily dose that you can tolerate. The first dose of SUBOXONE FILM should preferably be taken at least 24 hours after your last dose of methadone or when the first signs of craving appear.

How to use SUBOXONE FILM

• Before touching the film, make sure your hands are dry. SUBOXONE FILM should be held between
  2 fingers by the outside edges of the film.
• The films are taken sublingually and/or buccally. This means that you place the film under your tongue and/ or inside either cheek and allow it to dissolve, which may take between 4 and 8 minutes. This is the only way the films should be taken. If you need to take two films, place them on opposite sides under your tongue or inside your cheeks and try not to have them overlap. If you are taking more than 2 films, place the next films under your tongue or inside your cheeks after the first two have dissolved.
• During your treatment, your doctor may increase your dose of SUBOXONE FILM up to a maximum daily dose of 32 mg, depending upon your response to treatment.
• After a period of successful treatment, your doctor may gradually reduce your dose.
• Depending on your condition, your dose may continue to be reduced under careful medical supervision, until it is stopped altogether.

DO NOT swallow, consume food or drink until the films are completely dissolved. The films will not work if you chew of swallow them whole. They are not designed to be split or broken.

DO NOT inject SUBOXONE FILM. Patients have died from injecting this medicine. Additionally, when injecting SUBOXONE FILM and also taking benzodiazepines (medicines used to treat anxiety or sleeping problems), people were even more likely to die.
