1. What BuTrans are and what
they are used for
BuTrans 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, longlasting pain that requires the use of a
strong painkiller.
BuTrans should not be used to relieve
acute pain.
BuTrans 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 BuTrans
Do not
use BuTrans:

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,
moclobamide 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

BuTrans must not be used to treat
symptoms associated with drug
Warnings and precautions
Talk to your doctor, pharmacist or
nurse before using BuTrans:
 if you suffer from seizures, fits or
 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
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
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 BuTrans
Tell your doctor or pharmacist if you
are taking, have recently taken or
might take any other medicines.
 BuTrans 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
BuTrans may be reduced.

BuTrans 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
BuTrans 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

Using BuTrans with food, drink and
Alcohol may make some of the side
effects worse and you may feel unwell
if you drink alcohol whilst wearing
BuTrans. Drinking alcohol whilst using
BuTrans may also affect your reaction
Pregnancy breast-feeding and
You should not use BuTrans if you are
pregnant or are breast- feeding, think
you may be pregnant or are planning
to have a baby.
Ask your doctor or pharmacist for
advice before taking this medicine.
Driving and using machines
BuTrans 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 BuTrans, or for 24 hours
after removing the patch.
The medicine can affect your ability to
drive as it may make you sleepy or
 Do not drive while taking this
medicine until you know how it
affects you.
 It is an offence to drive while you
have this medicine in your body
over a specified limit unless you
have a defence (called the
‘statutory defence’).
 This defence applies when:
 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 and in the
information provided with the
 Please note that it is still an
offence to drive if you are unfit
because of the medicine (i.e. your
ability to drive is being affected).
Details regarding a new driving
offence concerning driving after drugs
have been taken in the UK may be
found here:
Talk to your doctor or pharmacist if
you are not sure whether it is safe for
you to drive while taking this

3. How to use BuTrans
Always use this medicine exactly as
your doctor or pharmacist has told
you. Check with your doctor or
pharmacist if you are not sure.
Three different strengths of BuTrans
are available. Your doctor will decide
which strength of BuTrans patch will
suit you best.
When people first start using BuTrans,
they often experience some nausea
and vomiting (see section 4). This
usually passes after the first week of

It's a good idea to book a follow-up
appointment with your doctor a week
or two after you first start using
BuTrans 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
Adults and elderly patients
Unless your doctor has told you
differently, attach one BuTrans 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 BuTrans
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.

The BuTrans 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.

Patients under 18 years of age
BuTrans should not be used in
patients below the age of 18 years.

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

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

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.

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

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.

Before applying the BuTrans 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.

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 BuTrans (see’ Warnings and
precautions' section).
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
 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
 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 BuTrans
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
BuTrans’ below).
If you feel that the effect of the
BuTrans patch is too weak or too
strong, talk to your doctor or

If you use more BuTrans than you
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 BuTrans
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 BuTrans
If you stop using BuTrans 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 BuTrans 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 BuTrans
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.

4. Possible side effects

reactions, although serious allergic
reactions are rare. Remove the patch
and tell your doctor immediately if you
get any sudden wheeziness,
difficulties in breathing, swelling of the
