You should not take PALEXIA® IR during childbirth because it could lead to dangerously slow or shallow breathing (respiratory depression) in the newborn.

Your doctor will discuss the risks and benefits of using PALEXIA® IR.

There is a risk of abuse or addiction with pain medicines such as PALEXIA® IR. If you have abused drugs in the past, you may have a higher chance of developing abuse or addiction again while using PALEXIA® IR.

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. 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

Depending on the medical condition for which you require PALEXIA® IR, your doctor may tell you to take it for only a day or two or longer, up to a few months or more.

Take the tablets every day for as long as your doctor tells you to. If you stop taking PALEXIA® IR too soon, your pain is likely to return.

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)

Immediately telephone your doctor or the Poison
s Information Centre (131 126) or go to accident and emergency at your nearest hospital, if you think that you or anyone else may have taken too much PALEXIA® IR. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.

If you take too many PALEXIA® IR tablets, this may result in vomiting, pin-point pupils, fast heartbeat, difficulty breathing or stopping breathing, drop in blood pressure , epileptic fits, convulsion, disturbed consciousness, collapse or loss of consciousness (coma). If you experience any of these, seek urgent medical attention.
