1. What Butec patches are and what they are used for

Butec patches contain the active ingredient buprenorphine which belongs to a group of medicines called strong analgesics or ‘painkillers’.

They have been prescribed for you by your doctor to relieve moderate, long-lasting pain that requires the use of a strong painkiller.

Butec patches should not be used to relieve acute pain.

Butec 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 Butec patches

Do not use Butec 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 tranylcypromide, phenelzine, isocarboxazid, modobamide and linezolid), or you have taken this type of medicine in the last two

•    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.

Butec patches must not be used to

treat symptoms associated with drug

withdrawal.

War nings and precautions

Talk to your doctor, pharmacist or nurse

before using Butec patches:

•    if you suffer from seizures, fits or convulsions;

•    if you 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;

•    if you are feeling light-headed or

•    if you have severe liver problems;

•    if you have ever been addicted to drugs or alcohol;

•    if you have a high temperature, as this may lead to larger quantities of the active ingredient being absorbed into the blood than nonnal.

Children and adolescents

Do not give this medicine to children

below 18 years.

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

*    Butec patches must not be used together with a type of medicine known as a monoamine oxidase inhibitor (examples include tranylcypromide, phenelzine, isocarboxazid, moclobamide and linezolid), or if you have taken this type of medicine in the last two

*    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 Butec patches may be reduced.

*    Butec 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.

* Butee 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 Butee 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 Butee patches. Drinking alcohol whilst using Butee patches may also affect your reaction time.

3. How to use Butee patches

Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist

Three different strengths of Butee patches are available. Your doctor will decide which strength of Butee patch 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, rqr to a maximum total dose of 40 micrograms hour.

Adults and elderly patients Unless your doctor has told you differently, attach one Butee patch (as described in detail below) and change it eveiy 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 Butee 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 Butee 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 Butee patch may be affected and your doctor will therefore check on you more closely. Before applying the Butee patch • Choose an area of non-initated, 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.

•    Ihe Butee 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

•    Ihe 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 ofthe patch is covered with a silvery protective foil. Carefully peel off half the foil. Tty 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. Mike 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. Rovided that you have applied the patch conectly, 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 Butee 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 ihe 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 lime of

Duration of treatment

Your doctor will tell you how long you should be treated with the 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 patches” below).

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

If you use more Butec 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 breaking difficulties or lose consciousness and may need emergency treatment in hospital. When seeking medical attention make sure that you take Ihis leaflet and any remaining patches with you to show to the doctor. If you forget to apply the Butec 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 Butec patches If you stop using Butec patches too soon or you interrupt your treataent 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 wilh 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 Butec patches 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 Butec patch is maintained for some time after removal of Ihe patch. You should not start another opioid analgesic (strong painkiller) within 24 hours after removal of the patch.
