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,
Transtec must not be used to treat withdrawal symptoms in drug-dependent persons.
Take special care with Transtec,
Also, please be aware of the following precautions:
Athletes should be aware that this medicine may cause a positive reaction to sports doping control tests.
Sleep-related breathing disorders
Transtec contains an active substance that belongs to the group of opioids. Opioids can cause sleep-related breathing disorders, for example central sleep apnea (shallow/pause of breathing during sleep) and sleep-related hypoxemia (low level of oxygen in the blood).
The risk of experiencing central sleep apnea is dependent on the dose of opioids. Your doctor may consider decreasing your total opioid dosage if you experience central sleep apnea.
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.
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.

Method of administration
Before applying the transdermal patch
Applying the transdermal patch:
Each transdermal patch is sealed in a sachet. Cut the child-re resistant sachet along the dotted line with scissors. Be careful not to damage the transdermal patches.
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
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.
