1. What Durogesic Matrix is and what it is used for

This medicine is called Durogesic Matrix

The patches help to relieve very strong and long-lasting pain:

• in adults who need long-term pain relief
• in children over 2 years of age who are already using opioid medicines and need long-term pain relief.

Durogesic Matrix contains a medicine called fentanyl. It belongs to a group of strong pain-relieving medicines called opioids.

2. What you need to know before you use Durogesic Matrix

Do not use Durogesic Matrix

• If you are allergic to fentanyl or any of the other ingredients of this medicine (listed in section 6)
• If you have pain that is not persistent, such as acute pain or pain after an operation
• If you have breathing difficulties, with slow or shallow breathing

Do not use this medicine if you or your child are in any of these situations. If you are not sure, consult your doctor or pharmacist before using Durogesic Matrix.

Warnings and precautions

• Durogesic Matrix can have serious life-threatening side effects in people who are not using opioids regularly.
• Durogesic Matrix is a medicine that can be life-threatening to children, even if the patches have been used. Be aware that a sticky patch (used or unused) can be tempting to a child, and if it sticks to the child's skin or if the child puts it in their mouth, it can be fatal.
• Keep this medicine in a safe place out of the reach of other people, see section 5 for more information.

If the patch sticks to another person

The patch should only be used on the skin of the person it has been prescribed for. There have been cases where the patch has stuck 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 shallow breathing that can be life-threatening. If the patch sticks to another person's skin, it should be removed immediately and a doctor should be consulted.

Be careful with Durogesic Matrix

Consult your doctor or pharmacist beforeusing this medicine if you are in any of the following situations. Your doctor will need to keep a closer check on you:

• If you have ever had breathing problems or lung disease.
• If you have ever had heart, liver or kidney problems, or low blood pressure.
• If you have ever had a brain tumour.
• If you have ever had persistent headaches or a head injury.
• If you are elderly, as you may be more sensitive to the effects of this medicine.
• If you have a condition called "myasthenia gravis", where your muscles are weak and tire easily.

If you have any of these conditions (or if you are not sure), consult your doctor or pharmacist before using Durogesic Matrix.

Tell your doctor while you are using the patch if you have breathing problems while you are sleeping.Opioids like Durogesic Matrix can cause sleep-related breathing disorders such as sleep apnoea (breathing pauses while you are asleep) and sleep-related low oxygen levels in the blood. Talk to your doctor if you, your partner or carer notice any of the following symptoms:

• breathing pauses while you are asleep
• waking up during the night feeling short of breath
• difficulty staying asleep
• excessive drowsiness during the day.

Your doctor may decide to change the dose.

Tell your doctor while you are using the patch if you notice any change in your pain.If you:

• feel that the patch is no longer relieving your pain
• have an increase in your pain
• notice a change in the way you feel pain (for example, you feel pain in a different part of your body)
• feel pain even when there is no reason for it (for example, when you touch something that shouldn't hurt)

Do not change the dose yourself. Your doctor may decide to change the dose or switch to a different treatment.

Side effects and Durogesic Matrix

• Durogesic Matrix can make you feel extremely drowsy and can slow down your breathing. In rare cases, these breathing problems can be life-threatening or even fatal, especially in people who have not used strong opioid painkillers like Durogesic Matrix or morphine before. If you, or your partner or carer, notice that you are unusually drowsy, with slow or shallow breathing:

• remove the patch;
• call a doctor or go to the nearest hospital immediately;
• try to keep the person awake and talking as much as possible.

• If you have a fever while using Durogesic Matrix, talk to your doctor. This can increase the amount of medicine that passes through your skin.
• Durogesic Matrix can cause constipation; talk to your doctor or pharmacist for advice on how to prevent or relieve constipation.

You can find a list of all 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, hot water bottles, electric blankets, heated water beds, heat lamps or saunas. Do not take a hot bath or shower, and do not use a hot tub or whirlpool. If you do, you may get too much medicine.

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 better for you to increase the 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 be life-threatening. The risk of these side effects may be higher with higher doses and longer use. Dependence or addiction can lead to a feeling of loss of 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 higher if:

• You or a member of your family have abused alcohol, prescription medicines or illegal drugs ("addiction").
• You smoke.
• You have ever had mental problems (depression, anxiety or personality disorders) or have received treatment from a psychiatrist for other mental illnesses.

If you notice any of the following symptoms while using Durogesic Matrix, it could be a sign of dependence or addiction.

• You need to use the medicine for longer than your doctor has prescribed.

• You need to use a higher dose than recommended.

• You are using the medicine for reasons other than those prescribed, for example, "to feel calm" or "to help you sleep".
• You have tried to stop using the medicine but couldn't.
• You feel unwell when you stop using the medicine, and you feel better once you start using it again ("withdrawal symptoms").

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 it safely.

Withdrawal symptoms when stopping Durogesic Matrix

Do not stop using this medicine suddenly. You may get withdrawal symptoms such as restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling sick or being sick, diarrhoea, loss of appetite, shaking, 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 so that any unpleasant withdrawal effects are minimised.

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 following medicines (or if you stop taking any of the following medicines), as this can affect the dose of Durogesic Matrix that you need.

In particular, tell your doctor or pharmacist if you are taking:

• Other pain-relieving medicines, such as other opioids (e.g. buprenorphine, nalbuphine or pentazocine) and some pain-relieving medicines for nerve pain (gabapentin and pregabalin).
• Medicines to help you sleep (such as temazepam, zaleplon or zolpidem).
• Medicines to calm you (tranquillisers, such as alprazolam, clonazepam, diazepam, hydroxyzine or lorazepam) and medicines for mental health conditions (antipsychotics, such as aripiprazole, haloperidol, olanzapine, risperidone or phenothiazines).
• Medicines to relax your muscles (such as cyclobenzaprine or diazepam).
• Certain medicines for depression called SSRIs or SNRIs (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline or venlafaxine) – see below for more information.
• Certain medicines for depression or Parkinson's disease called MAOIs (such as isocarboxazid, phenelzine, selegiline or tranylcypromine). You should not use Durogesic Matrix in the 14 days after stopping these medicines – see below for more information.
• Certain antihistamines, especially those that make you drowsy (such as chlorphenamine, clemastine, cyproheptadine, diphenhydramine or hydroxyzine).
• Certain antibiotics used to treat infections (such as erythromycin or clarithromycin).
• Medicines used to treat fungal infections (such as itraconazole, ketoconazole, fluconazole or voriconazole).
• Medicines used to treat HIV infection (such as ritonavir).
• Medicines used to treat irregular heartbeats (such as amiodarone, diltiazem or verapamil).
• Medicines used to treat tuberculosis (such as rifampicin).
• Certain medicines used to treat epilepsy (such as carbamazepine, phenobarbital or phenytoin).
• Certain medicines used to treat nausea or vomiting (such as phenothiazines).
• Certain medicines used to treat heartburn or stomach ulcers (such as cimetidine).
• Certain medicines used to treat angina (chest pain) or high blood pressure (such as nicardipine).
• Certain medicines used to treat blood cancer (such as idelalisib).

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 diarrhoea (these could be signs of a condition called serotonin syndrome). If they are used together, your doctor may want to keep a close eye on you to watch for these side effects, especially when starting treatment or when the dose of the medicine is changed.

Using Durogesic Matrix with central nervous system depressants, including alcohol and some narcotics

Taking 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 carefully. 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.

Use in athletes

Athletes are informed that this medicine contains a component that may result in a positive doping test.

Operations

If you think you are going to have an anaesthetic, tell your doctor or dentist that you are using Durogesic Matrix.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Durogesic Matrix should not be used during pregnancy, unless you have discussed it with your doctor.

Durogesic Matrix should not be used during labour, as the medicine can affect the breathing of the newborn baby.

Long-term use of Durogesic Matrix during pregnancy may cause withdrawal symptoms in your newborn baby, such as high-pitched crying, irritability, hyperactivity, convulsions, poor feeding and diarrhoea, which can be life-threatening if not recognised and treated. Talk to your doctor immediately if you think your baby may have withdrawal symptoms.

Do not use Durogesic Matrix if you are breastfeeding. You should not breastfeed for 3 days after removing the Durogesic Matrix patch. This is because the medicine can pass into breast milk.

Driving and using machines

Durogesic Matrix can affect your ability to drive or use machines or tools, as it may make you feel drowsy or dizzy. If this happens, do not drive or use machines or tools. Do not drive while using this medicine until you know how it affects you.

Talk to your doctor or pharmacist if you are unsure whether it is safe for you to drive while using this medicine.
