Warnings and Precautions
Consult your doctor or pharmacist before starting to take YANTIL retard 50 mg:
This medication contains tapentadol, which is an opioid medication. Repeated use of opioid analgesics can lead to tolerance (you may get used to it) and dependence, which can result in potentially life-threatening overdose. It is essential to inform your doctor if you think you may have developed dependence on YANTIL retard 50 mg. Its use (even at therapeutic doses) can cause physical dependence, which may lead to withdrawal symptoms and recurrence of your problems if you stop taking this medication abruptly.
YANTIL retard 50 mg can cause physical and psychological addiction. If you have a tendency to abuse medications or are dependent on medications, 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 of age.
Sleep-Related Breathing Disorders
YANTIL retard 50 mg may cause sleep-related breathing 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 YANTIL retard 50 mg with Other Medications
Inform your doctor or pharmacist if you are taking, have recently taken, or may need to 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 YANTIL retard 50 mg simultaneously with these medications. Your doctor will tell you if YANTIL retard 50 mg is suitable for you.
The concomitant use of YANTIL retard 50 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 life-threatening. Due to this, concomitant use should only be considered when other treatment options are not possible.
However, if your doctor prescribes YANTIL retard 50 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 life-threatening.
Inform your doctor if you are taking gabapentin or pregabalin or any other sedative medication, and follow your doctor's dosage recommendations strictly. It may be helpful to inform your friends and family about the signs and symptoms indicated 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 medications for treating depression), talk to your doctor before taking YANTIL retard 50 mg, as there have been cases of "serotonin syndrome". Serotonin syndrome is a rare but potentially life-threatening disorder. Symptoms can include involuntary 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 additional information.
The concomitant administration of YANTIL retard 50 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 YANTIL retard 50 mg may not have the same efficacy if administered with one of these medications. Inform your doctor if you are currently being treated with one of these medications.
The administration of YANTIL retard 50 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. Keep your doctor informed about all medications you are taking.
YANTIL retard 50 mg should not be taken with MAO inhibitors (medications for treating depression). Inform your doctor if you are taking MAO inhibitors or have taken them in the last 14 days.

Although tapentadol also affects neurotransmitters, experience in patients has not proven that it increases this risk.
