1. what palexia is and what it is used for

The full name of your medicine is ‘PALEXIA 50 mg film-coated tablets’. It is referred to as ‘PALEXIA’ in the rest of this leaflet.

Tapentadol – the active substance in PALEXIA – is a strong painkiller which belongs to the class of opioids. PALEXIA is used in adults for the treatment of moderate to severe pain of recent onset that can only be adequately managed with an opioid painkiller.

2. what you need to know before you take palexia

Do not take PALEXIA

• if you are allergic to tapentadol or any of the other ingredients of this medicine (listed in section 6)
• if you have asthma or if your breathing is dangerously slow or shallow (respiratory depression, hypercapnia)
• if you have no bowel movement as shown by severe constipation and bloating which may be accompanied by pain or discomfort in the lower stomach
• if you have poisoning with alcohol, sleeping pills, pain relievers or medicines that affect mood and emotions (see ‘Other medicines and PALEXIA’).

Warnings and precautions

Talk to your doctor or pharmacist before taking PALEXIA if you:

• have slow or shallow breathing
• suffer from increased pressure in the brain or are not fully conscious
• have had a head injury or brain tumors
• suffer from liver or kidney problems (see ‘How to take PALEXIA’)
• suffer from a pancreatic disease including inflammation of the pancreas (pancreatitis) or disease of the bile duct (biliary tract disease)
• are taking PALEXIA with medicines referred to as mixed opioid agonist/ antagonists (e.g., pentazocine, nalbuphine) or partial mu-opioid agonists (e.g. buprenorphine)
• have a tendency towards epilepsy or fits or if you are taking other medicines known to increase the risk of seizures because the risk of a fit may increase
• have a tendency to abuse medicines or if you are dependent on medicines, as PALEXIA may lead to addiction. In this case, you should only take these tablets for । short periods of time and under strict medical supervision.

Sleep-related breathing disorders.

PALEXIA 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.

Other medicines and PALEXIA

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Your doctor will tell you which medicines are safe to take with PALEXIA.

• The risk of side effects increases if you are taking medicines which may cause convulsions (fits), such as certain antidepressants or antipsychotics. The risk of having a fit may increase if you take PALEXIA at the same time. Your doctor will tell you whether PALEXIA is suitable for you.
• Concomitant use of PALEXIA and sedative medicines such as benzodiazepines or related drugs (certain sleeping pills or tranquillizers (e.g. barbiturates) or pain relievers such as opioids, morphine and codeine (also as cough medicine), antipsychotics, H1-antihistamines, alcohol) increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible. However if your doctor does prescribe PALEXIA together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor. Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms
• If you are taking a type of medicine that affects serotonin levels (e.g. certain medicines to treat depression), speak to your doctor before taking PALEXIA as there have been cases of “serotonin syndrome”. Serotonin syndrome is a rare, but life-threatening condition. The signs include involuntary, rhythmic contractions of muscles, including the muscles that control movement of the eye, agitation, excessive sweating, tremor, exaggeration of reflexes, increased muscle tension and body temperature above 38°C. Your doctor can advise you on this.
• PALEXIA may not work as well if taken with opioid like medicines (e.g. those containing pentazocine, nalbuphine or buprenorphine). Tell your doctor if you are currently being treated with one of these medicines.
• Taking PALEXIA with products (e.g. rifampicin, phenobarbital or St John’s Wort) that affect the enzymes required to remove PALEXIA from the body, may affect how well PALEXIA works or may cause side effects. The effects may occur especially when the other medication is started or stopped.
• PALEXIA should not be taken together with monoamine oxidase inhibitors (MAOIs – certain medicines for the treatment of depression). Tell your doctor if you are taking or have taken MAO inhibitors during the last 14 days.

Please keep your doctor informed about all medicines you are taking.

Taking PALEXIA with food, drink and alcohol

Do not drink alcohol whilst you are taking PALEXIA, because some side effects such as drowsiness may be increased. You can take PALEXIA with or without food.

Pregnancy and breast-feeding

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.

Do not take PALEXIA:

• if you are pregnant, unless your doctor has instructed you to do so, if used over prolonged periods during pregnancy, tapentadol may lead to withdrawal symptoms in the newborn baby, which might be life-threatening for the newborn if not recognized and treated by a doctor.
• if you become pregnant during treatment with PALEXIA. Check with your doctor.
• during childbirth, as it could lead to dangerously slow or shallow breathing (respiratory depression) in the newborn
• if you are breast-feeding, as it may pass into the breast milk.

Driving and using machines

If you feel drowsy, dizzy, have blurred vision or a slow reaction time whilst taking PALEXIA, then do not drive, use tools or machinery.

Any such effects are more likely to occur when you start taking PALEXIA, when the dose of PALEXIA is changed, or when you drink alcohol or take tranquilizers.

Please ask your doctor before driving a car or using machinery.

PALEXIA contains lactose.

Lactose is a type of sugar. If you have been told by your doctor that you have an intolerance to some sugars, talk to your doctor before taking this medicine.

Unknown

• Delirium

In general, the likelihood of having suicidal thoughts and behaviour is increased in patients suffering from chronic pain. In addition, certain medicines for the treatment of depression (which have an impact on the neurotransmitter system in the brain) may increase this risk, especially at the beginning of treatment. Although tapentadol also affects neurotransmitters, data from human use of tapentadol do not provide evidence for an increased risk.
