There have been cases where the patch has stuck accidentally to another family member through close physical contact or sharing the same bed with the person wearing the patch. If the patch sticks accidentally to another person (especially a child), the medicine in the patch can pass through their skin and can cause serious side effects, such as breathing difficulties, with slow or weak breathing that can be fatal. If the patch sticks to another person's skin, it should be removed immediately and a doctor should be consulted.

Side effects and Durogesic Matrix
You can find a complete list of possible side effects in section 4.
Durogesic Matrix, like other opioids, can affect the normal production of hormones in your body, such as cortisol, prolactin, or sex hormones, especially if you have used Durogesic Matrix for a long time. The effects of these hormonal changes can include feeling unwell or uneasy (including nausea), loss of appetite, tiredness, weakness, dizziness, low blood pressure, infertility, or decreased sex drive. Additionally, female patients may experience changes in their menstrual cycle, while male patients may experience impotence or enlarged breasts. If you notice any of these signs, talk to your doctor.
When you are wearing the patch, do not expose it to direct heat, such as heat pads, electric blankets, hot water bottles, water beds, heat lamps, or sunlamps. Do not take a hot bath or shower, or use a sauna or hot tub. If you do, you may increase the amount of medicine released from the patch.
Long-term use and tolerance
This medicine contains fentanyl, an opioid. Repeated use of opioid painkillers can make the medicine less effective (your body gets used to it, which is known as tolerance). You may also become more sensitive to pain when you use Durogesic Matrix. This is known as hyperalgesia. Increasing the dose of the patches may continue to relieve pain for a while, but it can also be harmful. If you notice that the medicine is becoming less effective, talk to your doctor. Your doctor will decide whether it is best to increase your dose or gradually reduce your use of Durogesic Matrix.
Dependence and addiction
Repeated use of Durogesic Matrix can also lead to dependence, abuse, and addiction, which can result in a potentially life-threatening overdose. The risk of these side effects may be greater with higher doses and longer use. Dependence or addiction can lead to a feeling of losing control over the amount of medicine you need to use or how often you need to use it. You may feel that you need to keep using the medicine even if it is no longer relieving your pain.
The risk of dependence or addiction varies from person to person. The risk of becoming dependent on or addicted to Durogesic Matrix may be greater if:
If you notice any of the following symptoms while using Durogesic Matrix, it could be a sign of dependence or addiction.
If you notice any of these signs, talk to your doctor to determine the best course of treatment for you, when it is appropriate to stop the medicine, and how to do so safely.
Withdrawal symptoms when stopping Durogesic Matrix
Do not stop using this medicine suddenly. You may experience withdrawal symptoms such as restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling sick, diarrhea, loss of appetite, tremors, chills, or sweating. If you want to stop using this medicine, talk to your doctor first. Your doctor will tell you how to do it, usually by gradually reducing the dose.
Other medicines and Durogesic Matrix
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This includes medicines you have bought without a prescription and herbal medicines. You should also tell your pharmacist if you are using Durogesic Matrix when you buy any medicines from the pharmacy.
Your doctor will know which medicines can be taken safely with Durogesic Matrix. You may need to be closely monitored if you are taking any of the types of medicines listed below, or if you stop taking any of the types of medicines listed below, as this can affect the dose of Durogesic Matrix you need.
In particular, tell your doctor or pharmacist if you are taking:
Using Durogesic Matrix with antidepressants
The risk of side effects increases if you are taking medicines such as certain antidepressants. Durogesic Matrix can interact with these medicines, and you may experience changes in your mental state, such as agitation, seeing, feeling, hearing, or smelling things that are not there (hallucinations), and other effects, such as changes in blood pressure, rapid heartbeat, high body temperature, overactive reflexes, lack of coordination, muscle stiffness, nausea, vomiting, and diarrhea (these could be signs of serotonin syndrome). If used together, your doctor may want to monitor you closely to detect these side effects, especially when starting treatment or changing the dose of the medicine.
Using Durogesic Matrix with central nervous system depressants, including alcohol and some narcotic medicines
Using Durogesic Matrix with sedative medicines, such as benzodiazepines or related medicines, increases the risk of drowsiness, breathing difficulties (respiratory depression), coma, and can be life-threatening. For this reason, concomitant use should only be considered when other treatment options are not possible.
However, if your doctor prescribes Durogesic Matrix with sedative medicines, your doctor will limit the dose and duration of concomitant treatment.
Tell your doctor about all sedative medicines you are taking, and follow your doctor's dosage recommendations strictly. It may be useful to inform friends or family members so they are aware of the signs and symptoms mentioned above. Contact your doctor if you experience these symptoms.
Do not drink alcohol while using Durogesic Matrix, unless you have talked to your doctor first.
