This medicine has been prescribed for you only. Do not pass it on to others. It may harm them,

6. Contents of the pack and other information

1. What Sevodyne is and what it is used for
Sevodyne contains 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.
Sevodyne should not be used to relieve acute pain.

2. What you need to know before you use Sevodyne
Do not use Sevodyne:
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, 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.
Sevodyne must not be used to treat symptoms associated with drug withdrawal.

Warnings and precautions
Talk to your doctor or pharmacist before using Sevodyne:
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 faint;
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 normal.
If you have recently had an operation, please speak to your doctor before using these patches.
Athletes should be aware that this medicine may cause a positive reaction to sports doping control tests.

Driving and using machines
Sevodyne 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 Sevodyne, or for 24 hours after removing the patch.
This 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.
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 Sevodyne
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 Sevodyne are available. Your doctor will decide which strength of Sevodyne
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 the Sevodyne 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 Sevodyne 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 Sevodyne. 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 Sevodyne may be affected and your doctor
will therefore check on you more closely.
Patients under 18 years of age
Sevodyne should not be used in patients below the age of 18 years.
Method of administration
Sevodyne transdermal patch is for transdermal use.
Sevodyne 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 accompanying illustrations). Ask for assistance if you cannot apply the patch yourself.

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

Upper arm






Other medicines and Sevodyne
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Sevodyne must not be used together with a type of medicine known as a monoamine oxidase inhibitor
(examples include tranylcypromide, 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 Sevodyne
may be reduced.
Sevodyne 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.
Sevodyne 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.
Sevodyne with alcohol
Alcohol may make some of the side effects worse and you may feel unwell if you drink alcohol whilst wearing
Sevodyne. Drinking alcohol whilst using Sevodyne may also affect your reaction time.

• The Sevodyne patch should be applied to a relatively hairless or nearly hairless skin site. If no suitable hair

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.
There is not sufficient experience regarding the use of buprenorphine in pregnant women. Therefore, you
should not use Sevodyne if you are pregnant or if you could become pregnant during treatment.
Buprenorphine, the active substance contained in the transdermal patch, may inhibit milk formation and
passes into the breast milk. Therefore, you should not use Sevodyne if you are breast-feeding.

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 Sevodyne (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 Sevodyne. Do not stop treatment without
consulting a doctor, because your pain may return and you may feel unwell (see also ‘If you stop using
Sevodyne’ below).
If you use more Sevodyne 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 Sevodyne
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 Sevodyne
If you stop using Sevodyne 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 Sevodyne 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 Sevodyne 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.
