Warnings and precautions

Consult your doctor or pharmacist before starting to take YANTIL retard 150 mg:

• if your breathing is slow or shallow,
• if you have increased intracranial pressure or altered consciousness, even to the point of coma,
• if you have had a head injury or brain tumors,
• if you have liver or kidney disease (see section “How to take YANTIL retard 150 mg”),
• if you have pancreatitis (inflammation of the pancreas) or biliary tract disease,
• if you are taking medications called mixed opioid agonist/antagonists (e.g., pentazocine, nalbuphine) or partial opioid agonists (e.g., buprenorphine),
• if you are prone to epilepsy or seizures, or if you are taking other medications known to increase the risk of seizures, as the risk of seizures may increase,
• if you or a family member has a history of alcohol abuse, prescription medication abuse, or illicit substance abuse (“addiction”),

This medicine contains tapentadol, which is an opioid medication. Repeated use of opioid analgesics can reduce the effectiveness of the medication (you may become accustomed to it). It may also lead to dependence and abuse, which can result in a potentially fatal overdose.It is essential to inform your doctor if you think you may have developed dependence on YANTIL retard 150 mg. Your use (even at therapeutic doses) may cause physical dependence, which may lead to withdrawal symptoms and a recurrence of your problems if you stop taking this medication abruptly.

YANTIL retard 150 mg can cause physical and psychological addiction. If you have a history of medication abuse or dependence, you should only take these tablets for short periods under strict medical supervision.

Children and adolescents

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

Do not administer this medication to children under 6 years old.

Respiratory problems related to sleep

YANTIL retard 150 mg may cause respiratory problems related to sleep, 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, nocturnal awakenings due to difficulty breathing, difficulty maintaining sleep, or excessive daytime somnolence. If you or someone else observes these symptoms, consult your doctor. Your doctor may consider reducing the dose.

Taking YANTIL retard 150 mg with other medicines

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

The risk of side effects increases if you are taking medications that can cause seizures (e.g., certain antidepressants or antipsychotics). The risk of seizures increases if you take YANTIL retard 150 mg simultaneously with these medications. Your doctor will tell you if YANTIL retard 150 mg is suitable for you.

The concomitant use of YANTIL retard 150 mg and sedatives such as benzodiazepines or related medications (certain sleeping pills or tranquilizers [e.g., barbiturates] or painkillers like opioids, morphine, and codeine [also used for cough] antipsychotics, H1 antihistamines, alcohol) increases the risk of drowsiness, respiratory difficulties (respiratory depression), coma, and may be potentially fatal. Therefore, only consider concomitant use when other treatment options are not possible.

However, if your doctor prescribes YANTIL retard 150 mg with sedatives, you should 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 may be potentially fatal.

Inform your doctor if you are taking gabapentin or pregabalin or any other sedative, and follow your doctor's dosage recommendations exactly. It may be helpful to inform your friends and family about the symptoms mentioned above. Inform your doctor if you experience any of these symptoms.

If you are taking a type of medication that affects serotonin levels (e.g., certain antidepressants), talk to your doctor before taking YANTIL retard 150 mg, as there have been cases of “serotonin syndrome.” Serotonin syndrome is a rare but potentially fatal condition. Symptoms may include involuntary muscle contractions, including those that control eye movement, agitation, excessive sweating, tremors, exaggerated reflexes, increased muscle tension, and a body temperature above 38°C. Your doctor may provide additional information.

This medication has not been studied in combination with other types of medications called mixed opioid agonist/antagonists (e.g., pentazocine, nalbuphine) or partial opioid agonists (e.g., buprenorphine). YANTIL retard 150 mg may not have the same effectiveness if taken with one of these medications. Inform your doctor if you are currently being treated with one of these medications.

The administration of YANTIL retard 150 mg with potent inhibitors or inducers (e.g., rifampicin, phenobarbital, St. John's wort) of certain enzymes necessary for eliminating tapentadol from your body may affect the efficacy of tapentadol or cause adverse effects, especially when starting or stopping this other type of medication. Inform your doctor about all the medications you are taking.

YANTIL retard 150 mg should not be taken with MAO inhibitors (medications for depression). Inform your doctor if you are taking MAO inhibitors or have taken them in the last 14 days.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, or if you think you may be pregnant, consult your doctor or pharmacist before using this medication.

Do not take this medication:

• if you are pregnant, unless your doctor has indicated otherwise, as tapentadol may cause withdrawal symptoms in the newborn, which can be life-threatening if not detected and treated by a doctor,
• during labor, as it may cause slow or shallow breathing to dangerous levels (respiratory depression) in the newborn,
• during breastfeeding, as it may be excreted in breast milk.

Driving and operating machinery

Ask your doctor if you can drive or operate machinery during treatment with YANTIL retard. It is essential to observe how this medication affects you before driving or operating machinery.

This medicine may cause allergic reactions. Symptoms may include wheezing (a whistling sound when breathing), difficulty breathing, inflammation of the eyelids, face, or lips, skin rash or itching, especially if it affects the entire body.

Another serious side effect consists of breathing more slowly or more weakly than normal. It occurs mainly in elderly patients or in weakened patients.

If you experience any of these important symptoms, consult your doctor immediately.

In general, the possibility of having suicidal thoughts and behaviors increases in patients with chronic pain. Additionally, some medications for treating depression (affecting neurotransmitters in the brain) may increase this risk, especially at the beginning of treatment. Although tapentadol also affects neurotransmitters, through experience in patients it has not been proven to increase this risk.
