Driving and using machines


Transtec may make you feel dizzy or drowsy or experience blurred or double vision and 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,
• when your dosage is changed,
• when you switch to Transtec from another pain reliever,
• if you also use other medicines that act on the brain,
• if you drink alcohol.
If you are affected, you should not drive or operate machinery whilst using Transtec. This
applies also at the end of treatment with Transtec. Do not drive or operate machinery for at
least 24 hours after the patch has been removed. Discuss with your doctor or pharmacist if you
are unsure about anything.

Transtec is an analgesic (a pain-relieving medicine) intended to relieve moderate to severe
cancer pain and severe pain that has not responded to other types of painkillers. Transtec acts
through the skin. When the transdermal patch is applied to the skin, the active substance
buprenorphine passes through the skin into the blood. Buprenorphine is an opioid (strong pain
reliever), which reduces pain by acting on the central nervous system (specific nerve cells in the
spinal cord and in the brain). The effect of the transdermal patch lasts for up to four days.
Transtec is not suitable for the treatment of acute (short-lasting) pain.



Do not use Transtec:

if you are allergic to buprenorphine or any of the other ingredients of this medicine (listed in
section 6);
• if you are dependent on strong pain relievers (opioids);
• if you suffer from a disease in which you have or may have great difficulty breathing;
• if you are taking monoamine oxidase (MAO) inhibitors (certain medicines used to treat
depression) or you have taken this type of medicine in the last two weeks (see “Other
medicines and Transtec”);
• if you suffer from myasthenia gravis (a certain type of severe muscle weakness);
• if you suffer from delirium tremens (confusion and trembling caused by abstinence from
alcohol following habitual excessive drinking or occurring during an episode of heavy alcohol
• if you are pregnant.
Transtec must not be used to treat withdrawal symptoms in drug-dependent persons.


Always use this medicine exactly as your doctor has told you. Check with your doctor or
pharmacist if you are not sure.
Transtec is available in three strengths: Transtec 35 micrograms/h transdermal patch, Transtec
52.5 micrograms/h transdermal patch and Transtec 70 micrograms/h transdermal patch.
The choice of which strength of Transtec will suit you best will be made by your doctor. During
treatment your doctor may change which transdermal patch you use to a smaller or larger one
if necessary.
The recommended dose is:


Unless your doctor has told you differently, attach one Transtec transdermal patch (as described
in detail below) and change it after 4 days at the latest. For convenience of use, you can change
the transdermal patch twice a week at the same days, e.g. always on Monday mornings and
Thursday evenings. To help you remember when to change your transdermal patch, you should
make a note on the calendar on the outer packaging. If your doctor has advised you to take
other pain relievers in addition to the transdermal patch, strictly follow the doctor’s instructions,
otherwise you will not fully benefit from treatment with Transtec.

Use in children and adolescents

Transtec should not be used in persons below the age of 18 years, because no experience has
so far been gained in this age group.

Elderly patients

No dosage adjustment is needed for elderly patients.

Patients with kidney disease/dialysis patients

In patients with kidney disease and in dialysis patients, no dosage adjustment is necessary.

Patients with liver disease

In patients with liver disease, the intensity and duration of action of Transtec may be affected.
If this applies to you, your doctor will check on you more closely.

Warnings and precautions

Method of administration
Before applying the transdermal patch

Talk to your doctor or pharmacist before using Transtec:
• if you have recently drunk a lot of alcohol;
• if you suffer from seizures or convulsions (fits);
• if your consciousness is disturbed (feeling light-headed or faint) for an unknown reason;
• if you are in a state of shock (cold sweat might be a sign of it);
• if the pressure in your skull is increased (for instance after head injury or in brain disease),
and artificial respiration is not possible;
• if you have difficulty breathing or are taking other medicines that may make you breathe
more slowly or weakly (see “Other medicines and Transtec”);
• if your liver does not work properly;
• if you are inclined to abuse medicines or drugs.

Also, please be aware of the following precautions:
• Some people may become dependent on strong pain relievers such as Transtec when they
use them over a long period of time. They may have withdrawal effects when they stop
using them (see “If you stop using Transtec”).
• Fever and external heat may lead to larger quantities of buprenorphine in the blood than
normal. Also, external heat may prevent the transdermal patch from sticking properly.
Therefore, do not expose yourself to external heat (e.g. sauna, infra-red lamps, electric
blankets, hot water bottles) and consult your doctor if you have fever.

Choose an area of skin which is flat,
clean and hairless on your upper body,
preferably on the chest below the
collar-bone or on the upper part of the
back (see adjacent illustrations).
Call assistance if you cannot apply the
transdermal patch yourself.
If the chosen area has hairs, cut them 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 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 at the notch. Take out the transdermal patch.

Athletes should be aware that this medicine may cause a positive reaction to sports doping
control tests.
Step 2:
The sticky side of the transdermal patch is covered with a silvery protective
foil. Carefully peel off half the foil. Try not to touch the sticky part of the
transdermal patch.

Children and adolescents

Transtec should not be used in persons below the age of 18 years, because no experience has
so far been gained in this age group.

Other medicines and Transtec

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other
• Transtec must not be used together with monoamine oxidase (MAO) inhibitors (certain
medicines used to treat depression), or if you have taken this type of medicine for the last 2
• Transtec may make some people feel drowsy, sick, or faint or make them breathe more
slowly or weakly. These side effects may be intensified if other medicines that may produce
the same effects are taken at the same time. These other medicines include other strong
pain relievers (opioids), certain sleeping pills, anaesthetics, and medicines used to treat
certain psychological diseases such as tranquillizers, anti-depressants, and neuroleptics.
• If Transtec is used together with some medicines, the effects of the transdermal patch may
be increased. These medicines include e.g. certain anti-infectives/anti-fungals (e.g.
containing erythromycin or ketoconazole) or HIV medicines (e.g. containing ritonavir)
• If Transtec is used together with other medicines, the effects of the transdermal patch may
be reduced. These medicines include certain products, e.g. dexamethasone; medicines to
treat epilepsy (e.g. containing carbamazepine, or phenytoin) or medicines for tuberculosis
(e.g. rifampicin).

Transtec with food, drink and alcohol

You should not drink alcohol while using Transtec. Alcohol may intensify certain side effects of
the transdermal patch and you may feel unwell. Drinking grapefruit juice may intensify the
effects of Transtec.

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 taking this medicine.
There is not sufficient experience regarding the use of Transtec in pregnant women. Therefore
do not use Transtec if you are pregnant.
Buprenorphine, the active substance contained in the transdermal patch, inhibits milk formation
and passes into the breast milk. Therefore, do not use Transtec if you are breast-feeding.

Step 3:
Stick the transdermal patch onto 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 for
about 30 seconds. Make sure that the whole transdermal patch is in contact
with your skin, especially at the edges.

Wearing the transdermal patch

You may wear the transdermal patch for up to 4 days. Provided that you have applied the
transdermal patch correctly, there is little risk of it coming off. You may shower, bathe or swim
while wearing it. However, do not expose the transdermal patch to extreme heat (e.g. sauna
baths, infra-red lamps, electric blankets, hot water bottles).
In the unlikely event that your transdermal patch falls off before it needs changing, do not use
the same transdermal 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.
Throw it away carefully, out of the sight and reach of children.
Stick a new transdermal patch on a different skin site (as described above). Wait at least
one week before using the same site again.

Duration of treatment

Your doctor will tell you how long you may use Transtec. Do not stop using Transtec on your
own account, because pain may return and you may feel unwell (see also “If you stop using
Transtec” below).
If you have the impression that the effect of the Transtec transdermal patch is too weak or too
strong, tell your doctor or pharmacist.

If you use more Transtec than you should

If this happens there may be signs of an overdose of the substance buprenorphine. An overdose
may intensify the side effects of buprenorphine such as drowsiness, nausea, and vomiting. You
may get pin-point pupils and breathing may become slow and weak. You may also get
cardiovascular collapse.
As soon as you discover that you have used more transdermal patches than you should, remove
the excess transdermal patches and talk to a doctor or pharmacist.

If you forget to use Transtec

If you forget an application, stick a new transdermal patch on as soon as you remember. You
will then need to change your routine, e.g. if you usually apply your transdermal patches on
Mondays and Thursdays, but you forget and don't stick on a new transdermal patch until
Wednesday, you will need to change your transdermal patches on Wednesdays and Saturdays
from then on. Make a note of the new pair of days on the calendar on the outer packaging. If
you are very late changing your transdermal patch, pain may return. In this case please contact
your doctor.
Never apply twice the number of transdermal patches to make up for the forgotten application!
If you interrupt or finish using Transtec too soon, pain may return. If you wish to stop use on
account of unpleasant side effects, please consult your doctor. He/she will tell you what can be
done and whether you can be treated with other medicines.
Some people may experience withdrawal-effects when they have used strong pain relievers for
a long time and stop using them. The risk of having effects after you stop using Transtec is very
low. However, if you feel agitated, anxious, nervous or shaky, if you are overactive, have
difficulty sleeping or digestion problems, tell your doctor.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
