Tapentadol - the active ingredient in Yantil - is a potent analgesic that belongs to the class of opioids.

Do not take Yantil:

Warnings and precautions

Consult your doctor or pharmacist before starting to take Yantil:

• if your breathing is slow or shallow,
• if you have increased intracranial pressure or altered consciousness to even coma,
• if you have had a head injury or brain tumors,
• if you have liver or kidney disease (see section “How to take Yantil”),
• 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”),
• if you smoke,
• if you have ever had mood problems (depression, anxiety, or personality disorder) or have received psychiatric treatment for other mental illnesses.

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

Yantil may cause physical and psychological addiction. If you have a tendency to abuse medications or have medication dependence, you should only take this medication for short periods of time under strict medical supervision.

Yantil has not been systematically evaluated in children and adolescents with obesity, therefore, pediatric patients with obesity should be closely monitored and the maximum recommended dose for each age group should not be exceeded.

Do not administer this medication to children under 2 years of age.

Sleep-related respiratory disorders

Yantil 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, 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 with other medications

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 may cause seizures (e.g. certain antidepressants or antipsychotics). The risk of seizures increases if you take Yantil simultaneously with these medications. Your doctor will tell you if Yantil is suitable for you.

• The concomitant use of Yantil and sedatives such as benzodiazepines or related medications (certain sleeping pills or tranquilizers [e.g. barbiturates] or painkillers such as opioids, morphine, and codeine [also as a cough medication], antipsychotics, H1 antihistamines, alcohol) increases the risk of drowsiness, respiratory difficulties (respiratory depression), coma, and may be potentially fatal. Due to this, concomitant use should only be considered when other treatment options are not possible.

However, if your doctor prescribes Yantil 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 members 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, 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 body temperature above 38°C. Your doctor may provide additional information.

• The concomitant administration of Yantil with other types of medications called mixed opioid agonist/antagonists (e.g. pentazocine, nalbuphine) or partial opioid agonists (e.g. buprenorphine) has not been systematically studied. Yantil 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 this medication with potent inhibitors or inducers (e.g. rifampicin, phenobarbital, St. John's wort) of certain enzymes necessary for the elimination of tapentadol from the 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 should not be taken with MAO inhibitors (medications for depression treatment). Inform your doctor if you are taking MAO inhibitors or have taken them in the last 14 days.

Taking Yantil with food, drinks, and alcohol

Do not consume alcohol while taking this medication, as some of its adverse 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, or 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 it, as tapentadol may cause withdrawal symptoms in the newborn, which may put the newborn's life at risk if not detected and treated by a doctor.

Yantil is not recommended:

• during delivery because it may cause slow or shallow breathing to dangerous levels (respiratory depression) in the newborn,
• during breastfeeding, as tapentadol may be excreted in breast milk.

Driving and operating machinery

Ask your doctor if you can drive or operate machinery during tapentadol treatment. It is essential to observe how this medication affects you before driving or operating machinery. Do not drive or operate machinery if you feel drowsy, dizzy, have blurred vision, or have difficulty concentrating. Be particularly careful at the start of treatment, after a dose change, and when taking it with alcohol or tranquilizers.
