What PALEXIA® IR is used for
PALEXIA® (tapentadol) IR is used to relieve severe pain. This strong pain reliever belongs to a group of medicines known as opioid analgesics.
This medicine is available only with a doctor’s prescription.
Your doctor may have prescribed PALEXIA® IR for another reason.
Ask your doctor if you have any questions about why PALEXIA® IR has been prescribed for you.
Before you take PALEXIA® IR
When you must not take it
You must not take PALEXIA® IR if you:
- are allergic to tapentadol or any of the ingredients listed at the end of this leaflet. Signs of allergic reaction may include a skin rash, itching, shortness of breath or swelling of the face, lips or tongue
- have asthma or if your breathing is dangerously slow or shallow (respiratory depression, hypercapnia)
- have paralysis of the gut
- have acute poisoning with alcohol, sleeping pills, pain relievers or other psychotropic medicines (medicines that affect mood and emotions)
- are taking medicine for depression containing a monoamine oxidase inhibitor (MAOI) medicine (such as Nardil, Parnate) or have taken a MAOI within the last 14 days. Ask your doctor or pharmacist if any of your medicines is an MAOI.
Do not take PALEXIA® IR if the packaging is torn or shows signs of tampering or the tablets do not look quite right.
Do not take PALEXIA® IR if the expiry date on the pack has passed.
You should only start taking PALEXIA® IR under direct supervision of your doctor due to the following risks:
You can become addicted to PALEXIA® IR even if you take it exactly as prescribed. PALEXIA® IR may become habit forming causing mental and physical dependence. If abused it may become less able to reduce pain.
As with all other opioid containing products, your body may become used to you taking PALEXIA® IR. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking PALEXIA® IR suddenly, so it is important to take it exactly as directed by your doctor.
Tolerance to PALEXIA® IR may develop, which means that the effect of the medicine may decrease. If this happens, more may be needed to maintain the same effect.
Continue taking your medicine for as long as your doctor tells you. If you stop having this medicine suddenly, your pain may worsen and you may experience some or all of the following withdrawal symptoms:
- nervousness, restlessness, agitation, trouble sleeping or anxiety
- body aches, weakness or stomach cramps
- loss of appetite, nausea, vomiting or diarrhoea
- increased heart rate, breathing rate or pupil size
- watery eyes, runny nose, chills or yawning
- increased sweating.
If you are not sure whether you should start taking this medicine, talk to your doctor.
Before you start to take it
Tell your doctor if you:
- have slow or shallow breathing
- have sleep-related breathing disorders
- suffer from increased pressure in the brain or disturbed consciousness up to coma
- have had a head injury or a brain tumour
- have had an epileptic fit or seizure or if you have an increased risk of having epileptic fits or seizures
- suffer from a liver or kidney disease
- suffer from a pancreatic or biliary tract disease including pancreatitis
- are breastfeeding
- are pregnant, or planning to become pregnant
- have an addiction or history of abuse of alcohol, opioids or other drugs
- have been told that you have an intolerance to some sugars. Lactose is an ingredient in these tablets.
Tell your doctor if you are pregnant or planning to become pregnant. You should not take PALEXIA® IR during pregnancy unless your doctor has told you to do so. Taking PALEXIA® IR during pregnancy may lead to withdrawal symptoms in the newborn baby. You should not take PALEXIA® IR during labour as it can cause breathing problems and signs of withdrawal in the newborn. Your doctor will discuss the risks and benefits of using PALEXIA® IR.
Tell your doctor if you are breastfeeding. You should not take PALEXIA® IR if you are breastfeeding as it may pass into your breast milk.
Taking other medicines
Tell your doctor if you are using any other medicines, including any that you buy without a prescription from a pharmacy, supermarket or health food shop.
Some medicines and PALEXIA® IR may interfere with each other. These medicines include:
- medicines for depression, sleeplessness or mental conditions such as selective serotonin reuptake inhibitors (SSRI’s), serotonin-norephinephrine reuptake inhibitors (SNRI’s), tricyclic anti-depressants (TCAs), monoamine oxidase inhibitor (MAOIs) and triptans
- other pain relievers such as morphine or codeine
- some cough medicines
- general anaesthetics such as propofol or midazolam (examples are Propofol™ or Midazolam™)
- medicines that slow the brain activity (central nervous system (CNS) depressants or phenothiazines). These medicines can be used to treat anxiety, muscle tension, pain, insomnia, acute stress reactions, panic attacks or seizure disorders such as sleeping pills, tranquilizers, hypnotics or sedatives (examples are Stelazine™, Largactil™, Valium™, Temaze™, or Xanax™).
Taking these medicines with PALEXIA® IR may increase the risk of possible side effects (see Side Effects). Your breathing may become seriously slow or shallow (respiratory depression) and your blood pressure may decrease. Your consciousness may be decreased, you may feel drowsier or feel that you might faint. If this happens tell your doctor.
Do not take PALEXIA® IR with alcohol. Some side effects such as drowsiness may be increased.
Other medications can also interfere with PALEXIA® IR and make you feel drowsy (see Warning information at the start of this document). Ask your doctor or pharmacist for more information.
How to take PALEXIA® IR
You should only start taking PALEXIA® IR under the direct supervision of your doctor.
Your doctor will tell you how much you should take, when and how often. It is important that you take this medicine as directed by your doctor.
If you are unsure ask your doctor or pharmacist.
How much to take
The usual dose is 1 tablet every 4 to 6 hours.
Your doctor may prescribe a different, more appropriate dose or interval of dosing, if this is necessary for you.
If you feel that the effect of these tablets is too strong or too weak, talk to your doctor or pharmacist.
PALEXIA® IR is not suitable for children and adolescents below the age of 18 years.
In elderly patients (above 65 years) usually no dose adjustment is necessary. However, the excretion of tapentadol may be delayed in some patients of this age group. If this applies to you, your doctor may recommend a different dosage regimen.
Patients with severe liver problems should not take these tablets. If you have moderate problems, your doctor will recommend a different dosage regimen.
Patients with severe kidney problems should not take these tablets.
Carefully follow all directions given to you by your doctor and pharmacist. These directions may differ from the information in this leaflet.
When and how should you take the tablets
PALEXIA® IR tablets should be swallowed whole with water. They may be taken, before, with, or after food.
Do not chew, divide or break the tablets. Chewing, dividing or breaking the tablets will release the medicine quickly and side effects may then occur.
How long to take it
This differs between individuals depending on how severe your pain is, how you respond to PALEXIA® IR and the cause of your pain. Ask your doctor for advice on how long you need to take PALEXIA® IR.
Carefully follow all directions given to you by your doctor and pharmacist. These directions may differ from the information contained in this leaflet.
If you forget to take it
If you forget to take a dose, you can take it as soon as you remember. The next dose should be taken after four or six hours, or as prescribed by your doctor.
Do not take a double dose to make up for the dose that you missed.
If you take too much (overdose)
If you or someone else receive too much (overdose), and experience one or more of the symptoms below, call triple zero (000) for an ambulance. Keep the person awake by talking to them or gently shaking them every now and then. You should follow the above steps even if someone other than you have accidentally used PALEXIA® IR that was prescribed for you. If someone takes an overdose, they may experience one or more of the following symptoms:
- Slow, unusual or difficult breathing
- Drowsiness, dizziness or unconsciousness
- Slow or weak heartbeat
- Nausea or vomiting
- Convulsions or fits
If you think you or someone else may have taken too much PALEXIA® IR, you should immediately:
- phone the Poisons Information Centre (by calling 13 11 26), or

You should do this even if there are no signs of discomfort or poisoning.
When seeking medical attention, take this leaflet and remaining medicine with you to show the doctor. Also tell them about any other medicines or alcohol which have been taken.
