• – Keep this leaflet. You may need to read it again.

• – If you have any further questions, ask your doctor, pharmacist or nurse.

• – This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if their signs of illness are the same as yours.

• 2. What you need to know before you use Rebrikel patches

• 3. How to use Rebrikel patches

• 4. Possible side effects

• 1. WHAT REBRIKEL PATCHES ARE AND WHAT THEY ARE USED FOR

This medicine has been prescribed for you for the relief of moderate, long-lasting pain that requires the use of a strong painkiller.

It contains the active ingredient buprenorphine which belongs to a class of medicines called opioids, which are ‘pain relievers’.

This medicine has been prescribed to you and should not be given to anyone else.

Opioids can cause addiction and you may get withdrawal symptoms if you stop taking it suddenly. Your prescriber should have explained how long you will be taking it for and when it is appropriate to stop, how to do this safely.

Rebrikel patches should not be used to relieve acute pain.

Rebrikel patches act through the skin. After application, buprenorphine passes through the skin into the blood. Each patch lasts for seven days.

2. what you need to know before you use rebrikel patches

Do not use Rebrikel patches :

• if you are allergic to buprenorphine or any of the other ingredients of this medicine (listed in section 6) if you have breathing problems;
• if you are addicted to drugs;
• if you are taking a type of medicine known as a monoamine oxidase inhibitor (examples include

tranylcypromine, phenelzine, isocarboxazid, moclobemide and linezolid), or you have taken this type of medicine in the last two weeks;

• if you suffer from myasthenia gravis (a condition in which the muscles become weak);
• if you have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating upon stopping taking alcohol.

Rebrikel patches must not be used to treat symptoms associated with drug withdrawal.

Warning and precautions

Talk to your doctor, pharmacist or nurse before using Rebrikel patches if you:

• suffer from seizures, fits or convulsions;
• have a severe headache or feel sick due to a head injury or increased pressure in your skull (for instance due to brain disease). This is because the patches may make symptoms worse or hide the extent of a head injury;
• are feeling light-headed or faint;
• have severe liver problems;
• have a high temperature, as this may lead to larger quantities of the active ingredient being absorbed into the blood than normal;
• have depression or other conditions that are treated with antidepressants. The use of these medicines together with Rebrikel patches can lead to serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Rebrikel patches”);
• are or have ever been addicted to opioids, alcohol, prescription medicines, or illegal drugs;
• have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating, when you have stopped taking alcohol or drugs;
• feel you need to use more Rebrikel patches to get the same level of pain relief, this may mean you are becoming tolerant to the effects of this medicine or are becoming addicted to it. Speak to your prescriber who will discuss your treatment and may change your dose or switch you to an alternative pain reliever.

Taking this medicine regularly, particularly for a long time, can lead to addiction. Your prescriber should have explained how long you will be taking it for and when it is appropriate to stop, how to do this safely.

Rarely, increasing the dose of this medicine can make you more sensitive to pain. If this happens, you need to speak to your prescriber about your treatment.

Addiction can cause withdrawal symptoms when you stop taking this medicine. Withdrawal symptoms can include restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling or being sick, diarrhoea, loss of appetite, shaking, shivering or sweating. Your prescriber will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop taking the medicine suddenly as you will be more likely to experience withdrawal symptoms.

Opioids should only be used by those they are prescribed for. Do not give your medicine to anyone else. Taking higher doses or more frequent doses of opioid, may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death.

Sleep-related breathing disorders.

Buprenophine can cause sleep-related breathing disorders such as sleep apnoea (breathing pauses during sleep) and sleep related hypoxemia (low oxygen level in the blood). The symptoms can include breathing pauses during sleep, night awakening due to shortness of breath, difficulties to maintain sleep or excessive drowsiness during the day. If you or another person observe these symptoms, contact your doctor. A dose reduction may be considered by your doctor.

If you have recently had an operation, please speak to your doctor before using these patches.

Children and adolescents

Do not give this medicine to children below 18 years.

Other medicines and Rebrikel patches

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

• Rebrikel patches must not be used together with a type of medicine known as a monoamine oxidase inhibitor (examples include tranylcypromine, phenelzine, isocarboxazid, moclobemide and linezolid), or if you have taken this type of medicine in the last two weeks.
• If you take some medicines such as phenobarbital or phenytoin (medicines commonly used to treat seizures, fits or convulsions), carbamazepine (a medicine to treat seizures, fits or convulsions and certain pain conditions), or rifampicin (a medicine to treat tuberculosis) the effects of Rebrikel patches may be reduced.
• Rebrikel patches may make some people feel drowsy, sick or faint or make them breathe more slowly or weakly. These side effects may be made worse if other medicines that produce the same effects are taken at the same time. These include certain medicines to treat pain, depression, anxiety, psychiatric or mental disorders, medicines to help you sleep, medicines to treat high blood pressure such as clonidine, other opioids (which may be found in painkillers or certain cough mixtures e.g. morphine, dextropropoxyphene, codeine, dextromethorphan, noscapine), antihistamines which make you drowsy, or anaesthetics such as halothane.
• Anti-depressants such as moclobemide, tranylcypromine, citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, duloxetine, venlafaxine, amitriptyline, doxepine, or trimipramine. These medicines may interact with Rebrikel patches and you may experience symptoms such as involuntary, rhythmic contractions of muscles, including the muscles that control movement of the eye, agitation, hallucinations, coma, excessive sweating, tremor, exaggeration of reflexes, increased muscle tension, body temperature above 38°C. Contact your doctor when experiencing such symptoms.
• Rebrikel patches must be used with caution if you are also taking benzodiazepines (medicines used to treat anxiety or to help you sleep). This combination may cause serious breathing problems.

Using Rebrikel patches with food, drink and alcohol

Alcohol may make some of the side effects worse and you may feel unwell if you drink alcohol whilst wearing Rebrikel patches. Drinking alcohol whilst using Rebrikel patches may also affect your reaction time.

Pregnancy, breast-feeding and fertility

Do not use Rebrikel patches if you are pregnant or think you might be pregnant unless you have discussed this with your prescriber and the benefits of treatment are considered to outweigh the potential harm to the baby.

If you use Rebrikel patches during pregnancy, your baby may become dependent and experience withdrawal symptoms after the birth which may need to be treated.

Do not use Rebrikel patches while you are breast-feeding as buprenorphine passes into breast milk and will affect your baby.

Driving and using machines

Rebrikel patches may affect your reactions to such an extent that you may not react adequately or quickly enough in the event of unexpected or sudden occurrences. This applies particularly:

• at the beginning of treatment;
• if you are taking medicines to treat anxiety or help you sleep;
• if your dose is increased.

If you are affected (e.g. feel dizzy, drowsy or have blurred vision), you should not drive or operate machinery whilst using Rebrikel patches, or for 24 hours after removing the patch.

The medicine can affect your ability to drive as it may make you sleepy or dizzy.

• Do not drive while taking this medicine until you know how it affects you.
• It is an offence to drive if this medicine affects your ability to drive.
• However, you would not be committing an offence if:
• The medicine has been prescribed to treat a medical or dental problem and
• You have taken it according to the instructions given by the prescriber or in the information provided with the medicine and
• It was not affecting your ability to drive safely

Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

3. how to use rebrikel patches

Your prescriber should have discussed with you, how long the course of Rebrikel patches will last. They will arrange a plan for stopping treatment. This will outline how to gradually reduce the dose and stop taking the medicine.

Always use Rebrikel patches exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Three different strengths of Rebrikel patches are available. Your doctor will decide which strength of Rebrikel patch will suit you best. When people first start using Rebrikel patches, they often experience some nausea and vomiting (see section 4). This usually passes after the first week of treatment. It’s a good idea to book a follow-up appointment with your doctor a week or two after you first start using Rebrikel patches to ensure that you are taking the correct dose and to manage any side effects. During treatment, your doctor may change the patch you use to a smaller or larger one if necessary. Do not cut or divide the patch or use a higher dose than recommended. You should not apply more than two patches at the same time, up to a maximum total dose of 40 micrograms/hour.

Adults and elderly patients

Unless your doctor has told you differently, attach one Rebrikel patch (as described in detail below) and change it every seventh day, preferably at the same time of day. Your doctor may wish to adjust the dose after 3–7 days until the correct level of pain control has been found. If your doctor has advised you to take other painkillers in addition to the patch, strictly follow the doctor’s instruc­tions, otherwise you will not fully benefit from treatment with the Rebrikel patch. The patch should be worn for 3 full days before increasing the dose, this is when the maximum effect of a given dose is established.

Patients under 18 years of age

Rebrikel patches should not be used in patients below the age of 18 years.

Patients with kidney disease/dialysis patients

In patients with kidney disease, no change in dose is necessary.

Patients with liver disease

In patients with liver disease, the effects and period of action of the Rebrikel patch may be affected and your doctor will therefore check on you more closely.

Before applying the Rebrikel patch

Choose an area of non-irritated, intact skin on your upper arm, outer arm, upper chest, upper back or side of the chest. (See illustrations below). Ask for assistance if you cannot apply the patch yourself.

The Rebrikel patch should be applied to a relatively hairless or nearly hairless skin site. If no suitable hair free sites are available the hairs should be cut off with a pair of scissors. Do not shave them off. Avoid skin which is red, irritated or has any other blemishes, for instance large scars.

The area of skin you choose must be dry and clean. If necessary, wash it with cold or lukewarm water. Do not use soap, alcohol, oil, lotions or other detergents. After a hot bath or shower, wait until your skin is completely dry and cool. Do not apply lotion, cream or ointment to the chosen area. This might prevent your patch from sticking properly.

Applying the patch

Step 1: Each patch is sealed in a pouch. Just before use, open the pouch by tearing where indicated. Take out the patch. Do not use the patch if the pouch seal is broken.

Step 2: The sticky side of the patch is covered with a silvery protective foil. Carefully peel off half the foil. Try not to touch the sticky part of the patch.

Step 3: Stick the patch on to the area of skin you have chosen and remove the remaining foil. Step 4: Press the patch against your skin with the palm of your hand and count slowly to 30. Make sure that the whole patch is in contact with your skin, especially at the edges.

Wearing the patch

You should wear the patch for seven days. Provided that you have applied the patch correctly, there is little risk of it coming off. If the edges of the patch begin to peel off, they may be taped down with a suitable skin tape.

You may shower, bathe or swim whilst wearing it.

Do not expose the patch to extreme heat (e.g. heating pads, electric blanket, heat lamps, sauna, hot tubs, heated water beds, hot water bottle, etc) as this may lead to larger quantities of the active ingredient being absorbed into the blood than normal. External heat may also prevent the patch from sticking properly. If you have a high temperature this may alter the effects of Rebrikel patches (see “Take special care” section above). In the unlikely event that your patch falls off before it needs changing, do not use the same patch again. Stick a new one on straight away (see “Changing the patch” below).

Changing the patch

• Take the old patch off.
• Fold it in half with the sticky side inwards.
• Open and take out a new patch. Use the empty pouch to dispose of the old patch. Now discard the pouch safely.
• Even used patches contain some active ingredient that may harm children or animals, so make sure your used patches are always kept out of the sight and reach of them.
• Stick a new patch on a different appropriate skin site (as described above). You should not apply a new patch to the same site for 3–4 weeks.
• Remember to change your patch at the same time of day. It is important that you make a note of the time of day.

Duration of treatment

Your doctor will tell you how long you should be treated with the Rebrikel patch. Do not stop treatment without consulting a doctor, because your pain may return and you may feel unwell (see also “If you stop using Rebrikel patches” below).

If you feel that the effect of the Rebrikel patch is too weak or too strong, talk to your doctor or pharmacist.

If you use more Rebrikel patches than you should

As soon as you discover that you have used more patches than you should, remove all patches and call your doctor or hospital straight away. People who have taken an overdose may feel very sleepy and sick. They may also have breathing difficulties or lose consciousness and may need emergency treatment in hospital. When seeking medical attention make sure that you take this leaflet and any remaining patches with you to show to the doctor.

If you forget to apply the Rebrikel patch

Stick a new patch on as soon as you remember. Also make a note of the date, as your usual day of changing may now be different. If you are very late changing your patch, your pain may return. In this case, please contact your doctor.

Do not apply additional patches to make up for the forgotten application.

If you stop using Rebrikel patches

Do not suddenly stop taking this medicine. If you want to stop taking this medicine, discuss this with your prescriber first. They will tell you how to do this, usually by reducing the dose gradually so that any unpleasant withdrawal effects are kept to a minimum. Withdrawal symptoms such as restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling or being sick, diarrhoea, shaking, shivering or sweating may occur if you suddenly stop taking this medicine.

If you stop using Rebrikel patches too soon or you interrupt your treatment your pain may return. If you wish to stop treatment please consult your doctor. They will tell you what can be done and whether you can be treated with other medicines.

The pain relieving effect of Rebrikel patch is maintained for some time after removal of the patch. You should not start another opioid analgesic (strong painkiller) within 24 hours after removal of the patch.

If you have any further questions on the use of this product, ask your doctor or pharmacist.

How do I know if I am addicted?

If you notice any of the following signs whilst using Rebrikel patches, it could be a sign that you have become addicted.

• – You need to take the medicine for longer than advised by the prescriber

• – You feel you need to use more than the recommended dose

• – You are using the medicine for reasons other than prescribed

• – When you stop taking the medicine you feel unwell, and you feel better once taking the medicine again

If you notice any of these signs, it is important you talk to your prescriber.
