1. What TRANSTEC is and what it is used for
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.
2. What you need to know before you use TRANSTEC
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 “Taking other medicines”);
– 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 consumption);
– if you are pregnant.
Transtec must not be used to treat withdrawal symptoms in drug-dependent persons.
Take special care with 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.
Athletes should be aware that this medicine may cause a positive reaction to sports doping control tests.
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 medicines.
– 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 weeks.
– 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).
Using 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.
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.
The 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 while you have this medicine in your body over a specified limit unless you have a defence (called the
• 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 medicine.
• 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).

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 TRANSTEC
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.
Always use Transtec exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
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. The following table
shows you when to change your patch
patch in evening of
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.
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.
Method of administration
Before applying the transdermal patch
– 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
– 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:
Each transdermal patch is sealed in a sachet. Just before use, open the sachet by tearing at the notch.
Take out the transdermal patch.
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.
Stick the transdermal patch onto the area of skin you have chosen and remove the remaining foil.
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.
How long will you use the patch for
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 stop using Transtec
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.
