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
are going to have an operation, or have just had an
operation, please tell the doctor at the hospital that you are taking these tablets. Your doctor may adjust your treatment. These tablets should not be used for short-term pain after an operation owing to the increased risk of dependence and breathlessness.
Tolerance, dependence and addiction
This medicine contains tapentadol, which is an opioid. It can cause dependence and/or addiction.
This medicine contains tapentadol which is an opioid medicine. Repeated use of opioid may result in the drug being less effective (you become accustomed to it, known as tolerance). Repeated use of LUPAXIS can also lead to dependence, abuse and addiction which may result in life-threatening overdose. The risk of these side effects can increase with a higher dose and longer duration of use.
Dependence or addiction can make you feel that you are no longer in control of how much medicine you need to take or how often you need to take it.
The risk of becoming dependent or addicted varies from person to person. You may have a greater risk of becoming dependent on or addicted to LUPAXIS if:
you or anyone in your family have ever abused or been
dependent on alcohol, prescription medicines or illegal drugs (“addiction”).
- you are a smoker.
you have ever had problems with your mood (depression,
anxiety or a personality disorder) or have been treated by a psychiatrist for other mental illnesses.
If you notice any of the following signs whilst taking LUPAXIS, it could be a sign that you have become dependent or addicted:
You need to take the medicine for longer than advised by
your doctor.
- You need to take more than the recommended dose.
You might feel that you need to carry on taking your
medicine, even when it doesn’t help to relieve your pain.
You are using the medicine for reasons other than
prescribed, for instance, ‘to stay calm’ or ‘help you sleep’
You have made repeated, unsuccessful attempts to quit or
control the use of the medicine.
When you stop taking the medicine you feel unwell,
and you feel better once taking the medicine again (‘withdrawal effects’).
If you notice any of these signs, speak to your doctor to discuss the best treatment pathway for you, including when it is appropriate to stop and how to stop safely (see section 3, If you stop taking LUPAXIS).
Children and adolescents
Children and adolescents 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 6 years.
Sleep-related breathing disorders
LUPAXIS 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.
Other medicines and LUPAXIS
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 Tapentadol.
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 Tapentadol at the same time. Your doctor will tell you whether Tapentadol is suitable for you.
Concomitant use of LUPAXIS and sedative medicines such
as benzodiazepines or related drugs (certain sleeping pills
or tranquillisers (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 LUPAXIS 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 LUPAXIS 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 oC. Your doctor can advise you on this
- Taking LUPAXIS together with other types of medicines referred to as mixed mu-opioid agonist/antagonists (e.g. pentazocine, nalbuphine) or partial mu-opioid agonists (e.g., buprenorphine) has not been studied. It is possible that LUPAXIS will not work as well if given together with one of these medicines. Tell your doctor in case you are currently treated with one of these medicines.
Taking LUPAXIS together with strong inhibitors or inducers
(e.g. rifampicin, phenobarbital, St John’s Wort) of certain enzymes that are necessary to eliminate LUPAXIS from your body, may influence how well tapentadol works or may cause side effects, especially when this other medication is started or stopped. Please keep your doctor informed about all medicines you are taking.
- LUPAXIS should not be taken together with monoamine oxidase inhibitors (certain medicines for the treatment of depression). Tell your doctor if you are taking MAO inhibitors or have taken these during the last 14 days. If you use LUPAXIS together with the below medicines that have anticholinergic effects the risk of side effects may be increased:
- medicines to treat depression.
medicines used to treat allergies, travel sickness or nausea
(antihistamines or antiemetics).
- medicines to treat psychiatric disorders (antipsychotics or neuroleptics);
- muscle relaxants.
- medicines to treat Parkinson’s disease.
LUPAXIS with food, drink and alcohol
Do not drink alcohol whilst you are taking LUPAXIS, because some side effects such as drowsiness may be increased. Food does not influence the effect of this medicine.
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 this tablets:
- if you are pregnant, unless your doctor has instructed you to do so, if used over prolonged periods during pregnancy, LUPAXIS 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
- during childbirth, because it could lead to dangerously slow or shallow breathing (respiratory depression) in the newborn
- during breast-feeding, because tapentadol may be excreted in the breast milk
Driving and using machines
LUPAXIS may cause drowsiness, dizziness and blurred vision and may impair your reactions. This may especially happen when you start taking LUPAXIS , when your doctor changes your dosage or when you drink alcohol or take tranquilizers. Please ask your doctor whether it is permitted to drive a car or use machines.
The medicine can affect your ability to drive.
- Do not drive while taking this medicine until you know how this medicine affects you.
- It may be an offence to drive if your ability to drive safely is affected.

3. How to take LUPAXIS
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
Before starting treatment and regularly during treatment, your doctor will discuss with you what you may expect from using LUPAXIS, when and how long you need to take it, when to contact your doctor, and when you need to stop it (see also“If you stop taking LUPAXIS” below).
Your doctor will adjust the dose according to the intensity of your pain and your individual pain sensitivity. In general, the lowest pain-relieving dose should be taken.
Adults
The usual dose is 1 tablet every 12 hours.
Total daily doses of Tapentadol greater than 500 mg tapentadol are not recommended.
Your doctor may prescribe a different, more appropriate dose or interval of dosing ,schedule 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.
Elderly patients
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. Liver or kidney disease (insufficiency)
Patients with severe liver problems should not take these tablets. If you have moderate problems, your doctor will recommend a different dosage regimen. In case of mild liver problems, a dosage adjustment is not required.
Patients with severe kidney problems should not take these tablets. In case of mild or moderate kidney problems, a dosage adjustment is not required.
Use in children and adolescents
The dose of LUPAXIS for children and adolescents aged 6 years to less than 18 years is dependent on age and body weight. The correct dose will be determined by your doctor. A total dose of 500 mg per day, i.e. 250 mg given every 12 hours should not be exceeded.
Children and adolescents with kidney or liver problems should not take these tablets.
LUPAXIS is not suitable for children below the age of 6 years. How should you take LUPAXIS
LUPAXIS is for oral use.
Always swallow the tablets whole, with sufficient liquid. Don’t chew it, break it or crush it – this could lead to overdosing, because the drug will be released into your body too quickly. You may take the tablets on an empty stomach or with meals. The empty shell of the tablet may not be digested completely and thus be seen in stool. This should not worry you, since the medicine (active substance) of the tablet has already been absorbed in your body and what you see is just the empty shell.

If you stop taking LUPAXIS
If you interrupt or stop treatment too soon, your pain is likely to return. If you wish to stop treatment, please tell your doctor first before stopping treatment.
