YANTIL 20 mg/ml ORAL SOLUTION

2. What you need to know before you take Yantil

Do not take Yantil:

• if you are allergic to tapentadol or any of the other ingredients of this medicine (listed in section 6),
• if you have asthma or if your breathing is slow or shallow to dangerous levels [respiratory depression; hypercapnia (higher than normal carbon dioxide levels in the blood)],
• if you have a disease in which the intestine does not work properly (paralytic ileus),
• if you have consumed alcohol, sleeping pills, other analgesics, or other psychotropic medicines (medicines that affect mood and emotions) at high doses (see section "Taking Yantil with other medicines").

Warnings and precautions

Consult your doctor or pharmacist before taking Yantil:

• if your breathing is slow or shallow,
• if you have increased intracranial pressure or altered consciousness up to 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 a disease of the pancreas (such as pancreatitis) or bile ducts,
• if you are taking medicines called mixed opioid agonist/antagonists (e.g., pentazocine, nalbuphine) or partial agonists of opioid μ receptors (e.g., buprenorphine),
• if you are prone to epilepsy or convulsive seizures, or if you are taking other medicines with a known risk of increasing seizures, as the risk of these seizures may increase,
• if you or a family member have a history of abuse or dependence on alcohol, prescription medicines, or illicit substances (“addiction”),
• if you smoke,
• if you have ever had problems with your mood (depression, anxiety, or personality disorder) or have received psychiatric treatment for other mental illnesses.

This medicine contains tapentadol, which is an opioid medicine. Repeated use of opioid analgesics can reduce their effectiveness (you can 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 Yantil. Its use (even at therapeutic doses) can cause physical dependence, which may cause you to suffer from withdrawal effects and a recurrence of your problems if you stop taking this treatment suddenly.

Yantil can cause physical and psychological addiction. If you have a tendency to abuse medicines or have drug dependence, you should only take this medicine for short periods 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 should not be exceeded.

Do not give this medicine to children under 2 years of age.

Sleep-related breathing disorders

Yantil 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 with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

• The risk of side effects increases if you are taking medicines that can cause seizures (attacks), such as certain antidepressants or antipsychotics. The risk of seizures increases if you take Yantil at the same time as these medicines. Your doctor will tell you if Yantil is suitable for you.

• Taking Yantil with sedative medicines such as benzodiazepines or related medicines (certain sleeping pills or tranquilizers [e.g., barbiturates] or analgesics like opioids, morphine, and codeine [also as a cough medicine], antipsychotics, antihistamines H1, alcohol) increases the risk of drowsiness, breathing 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 Yantil with sedative medicines, they will limit the dose and duration of concomitant treatment.

Taking opioids with medicines 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 medicine 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 medicine that affects serotonin levels (e.g., certain medicines for treating depression), talk to your doctor before taking Yantil, as there have been cases of "serotonin syndrome". Serotonin syndrome is a rare but potentially life-threatening disorder. Symptoms can include involuntary rhythmic contractions of the muscles, including the 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 more information.

• The concomitant administration of Yantil with other types of medicines 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 may not have the same efficacy if administered with one of these medicines. Tell your doctor if you are currently being treated with one of these medicines.

• Administration of this medicine 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 may cause side effects, especially when starting or stopping this other type of medication. Keep your doctor informed about all medicines you are taking.

• Yantil must not be taken with MAO inhibitors (medicines for treating depression). Tell your doctor if you are taking MAO inhibitors or if you have taken them in the last 14 days.

Taking Yantil with food, drinks, and alcohol

Do not consume alcohol while taking this medicine, as some of its side effects, such as drowsiness, may increase. The intake of food does not affect the effect of this medicine.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Do not take this medicine:

• if you are pregnant, unless your doctor has told you to do so. If used during prolonged periods during pregnancy, tapentadol may cause withdrawal symptoms in the newborn, which can be life-threatening to the newborn if not detected and treated by a doctor.

Yantil is not recommended:

• during labor 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 using machines

Ask your doctor if you can drive or use machines while taking tapentadol. It is essential that before driving or using machines, you observe how this medicine 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 administering it concomitantly with alcohol or tranquilizers.

Yantil contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per dose unit, i.e., it is essentially "sodium-free".

Yantil contains sodium benzoate

This medicine contains 5.9 mg of sodium benzoate in 5 ml of oral solution (maximum dose unit), which is equivalent to 1.18 mg/ml.

Benzoic acid salt may increase the risk of jaundice (yellowing of the skin and eyes) in newborns (up to 4 weeks of age).

Yantil contains propylene glycol

Frequency not known: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 proven that it increases this risk.

No additional side effects have been observed in children and adolescents.
