1. what busiete is and what it is used for

Busiete contains the active ingredient buprenorphine which belongs to a group of medicines called strong analgesics or ‘painkillers’. It has been prescribed for you by your doctor to relieve moderate, long-lasting pain that requires the use of a strong painkiller.

Busiete should not be used to relieve acute pain.

2. what you need to know before you use busiete are allergic to buprenorphine or any of the other ingredients of this medicine (listed in section 6)

• have breathing problems
• are addicted to drugs
• 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
• suffer from myasthenia gravis (a condition in which the muscles become weak)
• have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating upon stopping taking alcohol.

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

Warnings and precautions

Talk to your doctor or pharmacist before using Busiete 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 ever been addicted to drugs or alcohol
• have a high temperature, as this may lead to larger quantities of the active ingredient being absorbed into the blood than normal.
• if you have depression or other conditions that are treated with antidepressants.

The use of these medicines together with Busiete can lead to serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Busiete”).

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

Sleep-related breathing disorders

Busiete 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.

Athletes should be aware that this medicine may cause a positive reaction to sports doping control tests.

Children and adolescents

Do not give this medicine to children and adolescents below 18 years.

Other medicines and Busiete

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

Some medicines may increase the side effects of Busiete and may sometimes cause very serious reactions. Do not take any other medicines whilst using Busiete without first talking to your doctor, especially:

Anti-depressants such as moclobemide, tranylcypromine, citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, duloxetine, venlafaxine, amitriptyline, doxepine, or trimipramine. These medicines may interact with Busiete 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.

Busiete 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 Busiete may be reduced.

Busiete 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.

Concomitant use of Busiete and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be lifethreatening. Because of this, concomitant use should only be considered when other treatment options are not possible.

However if your doctor does prescribe Busiete together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor.

Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.

Busiete with alcohol

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

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Pregnancy

There is not sufficient experience regarding the use of buprenorphine in pregnant women. Therefore you should not use Busiete if you are pregnant or if you could become pregnant during treatment.

Breast-feeding

Buprenorphine, the active substance contained in the transdermal patch, may inhibit milk formation and passes into the breast milk. Therefore, you should not use Busiete if you are breast-feeding.

Driving and using machines

Busiete 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 Busiete, or for 24 hours after removing the patch.

Busiete 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 busiete

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

Different strengths of Busiete are available. Your doctor will decide which strength of Busiete will suit you best.

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.

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

Adults and elderly patients

Unless your doctor has told you differently, attach one Busiete 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 Busiete. 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 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 Busiete may be affected and your doctor will therefore check on you more closely.

Patients under 18 years of age

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

Method of administration

Busiete is for transdermal use.

Busiete acts through the skin. After application, buprenorphine passes through the skin into the blood.

Before applying the transdermal 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 beside). Ask for assistance if you cannot apply the patch yourself.

or

• Busiete 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 transdermal patch

• Step 1: Each transdermal patch is sealed in a sachet. Just before use, cut the sachet along the sealed edge with scissors. Take out the transdermal patch. Do not use the patch if the sachet seal is broken.
• Step 2: The sticky side of the transdermal patch is covered with a transparent protective foil. Carefully peel off one part of the foil. Try not to touch the sticky part of the transdermal patch.
• Step 3: Stick the transdermal patch on to the area of skin you have chosen and remove the remaining foil.
• Step 4: Press the transdermal patch against your skin with the palm of your hand and count slowly to 30. Make sure that the whole transdermal patch is in contact with your skin, especially at the edges.

Wearing the transdermal 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 Busiete (see “Warnings and precautions” 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 transdermal patch” below).

Changing the transdermal patch

• Take the old transdermal patch off.
• Fold it in half with the sticky side inwards.
• Open and take out a new patch. Use the empty sachet to dispose of the old patch. Now discard the sachet safely.
• Stick a new transdermal 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 Busiete. Do not stop treatment without consulting a doctor, because your pain may return and you may feel unwell (see also “If you stop using Busiete” below).

If you use more Busiete 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 use Busiete

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 Busiete

If you stop using Busiete 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.

Some people may have side effects when they have used strong painkillers for a long time and stop using them. The risk of having effects after stopping Busiete is very low. However, if you feel agitated, anxious, nervous or shaky, if you are overactive, have difficulty sleeping or digestive problems, tell your doctor.

The pain relieving effect of Busiete 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 medicine, ask your doctor or pharmacist.
