• suffer from increased pressure in the brain or are not fully conscious.
• have had a head injury or brain tumours.
• 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 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 this medicine for short periods of time and under strict medical supervision.
• or anyone in your family have ever abused or been dependent on alcohol, prescription medicines or illegal drugs (“addiction”).
• are a smoker.
• have ever had problems with your mood (depression, anxiety or a personality disorder) or have been treated by a psychiatrist for other mental illnesses.

This medicine contains tapentadol which is an opioid medicine. Repeated use of opioid painkillers may result in the drug being less effective (you become accustomed to it). It may also lead to dependence and abuse which may result in life-threatening overdose. If you have concern that you may become dependent on PALEXIA it is important that you consult your doctor. Use (even at therapeutic doses) may lead to physical dependence, which may result in you suffering withdrawal effects and a recurrence of your problems if you suddenly stop taking this medicine treatment.

Children with obesity should be monitored closely and the recommended maximum dose should not be exceeded.

Do not give this medicine to children below the age of 2 years or a body weight of less than 16 kg.

Sleep-related breathing disorders

PALEXIA can cause sleep-related breathing disorders such as sleep apnoea (breathing pauses during sleep) and sleep related hypoxemia (low oxygen level in the blood). The symptoms can include breathing pauses during sleep, night awakening due to shortness of breath, difficulties to maintain sleep or excessive drowsiness during the day. If you or another person observe these symptoms, contact your doctor. A dose reduction may be considered by your doctor.

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.
  The concomitant use of opioids and drugs used to treat epilepsy, nerve pain or anxiety (gabapentin and pregabalin) increases the risk of opioid overdose, respiratory depression and may be life-threatening.
  Please tell your doctor if you are taking gabapentin or pregabalin or any sedative medicines, 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.

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

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 this medicine:

• 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.

Use of PALEXIA is not recommended:

• during childbirth, as it could lead to dangerously slow or shallow breathing (respiratory depression) in the newborn
• if you are breast-feeding, as tapentadol may pass into the breast milk.

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.

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 if this medicine affects your ability to drive.
• However, you would not be committing an offence if:
  • 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 or in the information provided with the medicine and
  • It was not affecting your ability to drive safely

Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

PALEXIA is for oral use.

You may take the oral solution with or without food.

Use a dosing pipette and the adaptor provided in the pack to take the exact volume of the solution from the bottle as prescribed by your doctor. The volume corresponds to the prescribed dose.

• The bottle has a child resistant screw cap. To remove the cap, push it down and turn it anti-clockwise (Fig. 1). After the cap is removed, peel off the safety seal from the top of the bottle. If the safety seal is damaged, do not use this medicine and talk to your pharmacist.

• Place the bottle on a stable flat surface. Open the plastic bag containing the dosing pipette / adaptor at the perforated end and remove the dosing pipette (A) with the attached adaptor (B). Plug the adaptor with the dosing pipette firmly into the neck of the bottle (Fig 2).

• To fill the dosing pipette, turn the bottle upside down. Whilst holding the dosing pipette in place, gently pull the plunger (C) down to the line that matches the dose prescribed by your doctor (See section "How to take PALEXIA”). Do not remove the dosing pipette at this point! (Fig 3)

• Turn the bottle upright and then carefully remove the dosing pipette from the bottle. After you have removed the dosing pipette, carefully check that you have taken the right amount of the solution. The adaptor (B) that was previously attached to the dosing pipette should now remain in the bottle (Fig. 4).

• Take your medicine by placing the dosing pipette into your mouth and gently pressing the plunger. Press the plunger fully to ensure all solution is dispensed. If you prefer, you can dilute the medicine in a glass of water or a non-alcoholic drink before you take it; in this case drink the whole glass to ensure that you have taken the correct dose of medicine (Fig.5)
• Leave the adaptor in the bottle. Replace the cap and tightly close the bottle. Store the bottle in an upright position. After use, rinse the dosing pipette with water and allow it to dry. When you take your medicine the next time, place the dosing pipette into the adaptor in the neck of the bottle and follow the instructions above.

Do not take this medicine for longer than your doctor has told you.

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.

No Additional side effects were observed in children and adolescents.
