Contents of the package leaflet

PALEXIA 100 mg is used for the treatment of moderate to severe acute pain in adults, which can only be adequately treated with an opioid analgesic.
Do not take PALEXIA 100 mg:
Warnings and precautions
Consult your doctor or pharmacist before starting to take PALEXIA 100 mg:
This medication contains tapentadol, which is an opioid medication. Repeated use of opioid analgesics can reduce their effectiveness (you may get used to it). It can also lead to dependence and abuse, which can result in a potentially fatal overdose. It is essential that you inform your doctor if you think you may have developed dependence on PALEXIA 100 mg. Its use (even at therapeutic doses) can cause physical dependence, which may cause you to experience withdrawal symptoms and a recurrence of your problems if you stop taking this medication abruptly.
PALEXIA 100 mg can cause physical and psychological addiction. If you have a tendency to abuse medications or have medication dependence, you should only take these tablets for short periods under strict medical supervision.
Sleep-related respiratory disorders
PALEXIA 100 mg may cause sleep-related respiratory disorders such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). Symptoms may include pauses in breathing during sleep, nighttime awakenings due to difficulty breathing, difficulty maintaining sleep, or excessive daytime sleepiness. If you or someone else observes these symptoms, consult your doctor. Your doctor may consider reducing the dose.
Taking PALEXIA 100 mg with other medications
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medication.
The risk of side effects increases if you are taking medications that can cause seizures (attacks), such as certain antidepressants or antipsychotics. The risk of seizures increases if you take PALEXIA 100 mg simultaneously with these medications. Your doctor will tell you if PALEXIA 100 mg is suitable for you.
The concomitant use of PALEXIA 100 mg and sedative medications such as benzodiazepines or related medications (certain sleeping pills or tranquilizers [e.g., barbiturates] or analgesics like opioids, morphine, and codeine [also as a cough medication], antipsychotics, antihistamines H1, alcohol) increases the risk of drowsiness, respiratory difficulties (respiratory depression), coma, and can be potentially fatal. Due to this, concomitant use should only be considered when other treatment options are not possible.
However, if your doctor prescribes PALEXIA 100 mg with sedative medications, they will limit the dose and duration of concomitant treatment.
The concomitant use of opioids and medications used to treat epilepsy, nerve pain, or anxiety (gabapentin and pregabalin) increases the risk of opioid overdose, respiratory depression, and can be potentially fatal.
Tell your doctor if you are taking gabapentin or pregabalin or any other sedative medication, and follow your doctor's dosage recommendation to the letter. It may be helpful to inform your friends and family about the signs and symptoms mentioned above. Tell your doctor if you experience any of these symptoms.
If you are taking a type of medication that affects serotonin levels (e.g., certain medications for treating depression), talk to your doctor before taking PALEXIA 100 mg, as there have been cases of "serotonin syndrome". Serotonin syndrome is a rare but potentially life-threatening disorder. Symptoms can include involuntary rhythmic muscle contractions, including muscles that control eye movement, agitation, excessive sweating, tremors, exaggerated reflexes, increased muscle tension, and body temperature above 38°C. Your doctor can provide you with additional information.
The concomitant administration of PALEXIA 100 mg with other types of medications called mixed opioid agonist/antagonists (e.g., pentazocine, nalbuphine) or partial agonists of opioid μ receptors (e.g., buprenorphine) has not been studied. It is possible that PALEXIA 100 mg may not have the same efficacy if administered with one of these medications. Tell your doctor if you are currently being treated with one of these medications.
The administration of PALEXIA 100 mg with potent inhibitors or inducers (e.g., rifampicin, phenobarbital, St. John's Wort) of certain enzymes necessary for the elimination of tapentadol from your body may affect the efficacy of tapentadol or cause side effects, especially when starting or stopping this other type of medication. Keep your doctor informed about all medications you are taking.
PALEXIA 100 mg should not be taken with MAO inhibitors (medications for treating depression). Tell your doctor if you are taking MAO inhibitors or if you have taken them in the last 14 days.
Taking PALEXIA 100 mg with food, drinks, and alcohol
Do not consume alcohol while taking PALEXIA 100 mg, as some of its side effects, such as drowsiness, may increase. Food intake does not affect the effect of this medication.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.
Do not take this medication:
Driving and using machines
Ask your doctor if you can drive or use machines during treatment with PALEXIA. It is essential that before driving or using machines, you observe how this medication affects you. Do not drive or use machines if you feel drowsy, dizzy, have blurred vision, or have difficulty concentrating. Be particularly careful when starting treatment, after a dose change, and when taking it concomitantly with alcohol or tranquilizers.
PALEXIA 100 mg contains lactose
If your doctor has told you that you have an intolerance to certain sugars, consult them before taking this medication.
PALEXIA 100 mg contains sodium
This medication contains less than 1 mmol (23 mg) of sodium per tablet, so it is considered essentially "sodium-free".

Your doctor will adjust the dose based on the intensity of your pain and your personal sensitivity to pain. Generally, you should take the minimum effective dose to relieve pain.
Adults

Elderly patients
In elderly patients (over 65 years of age), the dose does not usually need to be adjusted. However, the elimination of tapentadol may be delayed and slower in some patients in this age group. If this applies to you, your doctor may prescribe a different dosing regimen.

Patients with severe liver problems should not take these tablets. If you have moderate liver problems, your doctor will prescribe a different dosing regimen. In case of mild liver problems, dose adjustment is not necessary.

Another serious side effect is breathing more slowly or more weakly than normal. This occurs mainly in elderly or debilitated patients.
If you experience any of these important symptoms, consult your doctor immediately.
Side effects that may occur:
Very common(may affect more than 1 in 10 people): nausea, vomiting, dizziness, drowsiness, headache.
Common(may affect up to 1 in 10 people): decreased appetite, anxiety, confusion, hallucinations, difficulty sleeping, sleep disturbances, tremors, hot flashes, constipation, diarrhea, indigestion, dry mouth, itching, increased sweating, skin rash, muscle cramps, feeling of weakness, fatigue, feeling of changed body temperature.
Uncommon(may affect up to 1 in 100 people): depression, disorientation, excitability (agitation), nervousness, restlessness, euphoric mood, attention disturbances, memory impairment, feeling of being about to faint, sedation, difficulty controlling movements, difficulty speaking, numbness, abnormal sensations in the skin (e.g., tingling, itching), muscle twitching, vision disturbances, rapid heartbeat, palpitations, decreased blood pressure, slow or shallow breathing to dangerous levels (respiratory depression), decreased oxygen levels in the blood, shortness of breath, abdominal discomfort, rash, feeling of heaviness, urinary retention, frequent urination, drug withdrawal syndrome (see section "If you stop taking PALEXIA 100 mg"), water retention in the tissues (edema), feeling of malaise, feeling of intoxication, irritability, feeling of relaxation.

Frequency not known(frequency cannot be estimated from available data): delirium.
In general, the possibility of having suicidal thoughts and behaviors increases in patients with chronic pain. Additionally, some medications for treating depression (with an impact on the brain's neurotransmitter system) may increase this risk, especially at the start of treatment. Although tapentadol also affects neurotransmitters, experience in patients has not shown that it increases this risk.
