ingredients of this medicine (listed in section 6)
• have breathing problems
• are addicted to drugs
• are taking a type of medicine known as a

Reletrans if you:
• recently drunk a lot of alcohol
• suffer from seizures, fits or convulsions
• have a severe headache or feel sick due to a

• Reletrans must not be used together with a
type of medicine known as a monoamine oxidase
(MAO) 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 Reletrans may be reduced.
• Reletrans 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.
• Reletrans 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 which could be fatal in case of
overdose. Tell your doctor if you are taking this
Reletrans with alcohol
Alcohol may make some of the side effects worse
and you may feel unwell if you drink alcohol whilst
using Reletrans. Drinking alcohol whilst using
Reletrans may also affect your reaction time.

How to use Reletrans
Always use this medicine exactly as your doctor
has told you. Check with your doctor or
pharmacist if you are not sure.
Different strengths of Reletrans are available.
Your doctor will decide which strength of
Reletrans will suit you best.
During treatment, your doctor may change the
transdermal patch you use to a smaller or larger
one if necessary, or tell you to use a combination
of up to two patches. You should not apply
more than two transdermal patches at the
same time up to a maximum total dose of
If you feel that the effect of the buprenorphine
transdermal patch is too weak or too strong,
talk to your doctor or pharmacist.
Unless your doctor has told you differently, attach
one Reletrans transdermal 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 transdermal patch,
strictly follow the doctor’s instructions, otherwise
you will not fully benefit from treatment with the
buprenorphine patch. The transdermal 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 liver disease
In patients with liver disease, the effects and
period of action of the buprenorphine transdermal
patch may be affected and your doctor will
therefore check on you more closely.
Use in children and adolescents
Reletrans transdermal patches should not be
used in patients below the age of 18 years.
Method of administration
Reletrans transdermal patch is for transdermal use.
The transdermal patches act through the skin.
After application, buprenorphine passes through
the skin into the blood.
Before applying Reletrans
• 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 transdermal patch yourself.
• The buprenorphine transdermal 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 transdermal patch from sticking properly.
Applying the transdermal patch
Step 1: Each transdermal patch is sealed in a
sachet. Just before use, open the sachet by tearing
where indicated. Take out the transdermal patch.
Continued on next page >>
For use in adults
Do not use the transdermal patch if the sachet
seal is broken.
Step 2: The sticky side of the transdermal patch
is covered with a transparent foil. Carefully peel
off half 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
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 transdermal patch for seven
days. Provided that you have applied the
transdermal patch correctly, there is little risk of it
coming off. If the edges of the transdermal 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 transdermal 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
transdermal patch from sticking properly. If you
have a high temperature this may alter the effects
of Reletrans (see “Warnings and precautions”
In the unlikely event that your transdermal 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 transdermal patch.
Use the empty sachet to dispose of the old
transdermal 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 transdermal patch to
the same site for 3-4 weeks.
• Remember to change your transdermal 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 Reletrans. Do not stop treatment
without consulting a doctor, because your pain
may return and you may feel unwell (see also
“If you stop using Reletrans” below).
If you use more Reletrans than you should
As soon as you discover that you have used more
transdermal patches than you should, remove all
transdermal 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 transdermal patches
with you to show to the doctor.
If you forget to apply Reletrans
Stick a new transdermal 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 transdermal patch, your
pain may return. In this case, please contact your
Do not apply additional transdermal patches to
make up for the forgotten application.
If you stop using Reletrans
If you stop using Reletrans 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 Reletrans 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 Reletrans is
maintained for some time after removal of the
transdermal patch. You should not start another
opioid analgesic (strong painkiller) within
24 hours after removal of the transdermal patch.
If you have any further questions on the use of
this medicine, ask your doctor or pharmacist.
