Other medicines and NUCYRETA TABLETS
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Your doctor will tell you which medicines are safe to take with NUCYRETA ER 50.
• Your breathing may become dangerously slow or shallow (respiratory depression) if you are taking certain sleeping pills or tranquilizers (e.g. barbiturates, benzodiazepines), or pain relievers such as morphine and codeine (also as cough medicine) in combination with NUCYRETA ER 50.
If this happens tell your doctor.
• Your consciousness may be decreased, you may feel drowsier or feel you might faint, if you take NUCYRETAwith sedatives (such as benzodiazepines), antipsychotics (medicines that affect the state of mind or emotions), H1-antihistamines, opioids or alcohol. If this happens tell your doctor.
• If you are taking a type of medicine that affects serotonin levels (e.g. certain medicines to treat depression), speak to your doctor before taking NUCYRETA as there have been cases of “serotonin syndrome”.
Serotonin syndrome is a rare, but life-threatening condition. The signs include confusion, restlessness, fever, sweating, uncoordinated movement of arms, legs or eyes, uncontrollable jerking of muscles, muscle twitches and diarrhoea. Your doctor can advise you on this.
• NUCYRETA may not work as well if taken with opioid like medicines (e.g. those containing pentazocine, nalbuphine or buprenorphine).
Tell your doctor if you are currently being treated with one of these medicines.
• Taking NUCYRETA with products (e.g. rifampicin, phenobarbital or St John’s
Wort) that affects the enzymes required to remove NUCYRETA from the body, may affect how well NUCYRETA works or may cause side effects. The effects may occur especially when the other medication is started or stopped.
• NUCYRETAshould not be taken together with monoamine oxidase inhibitors (MAOIs – certain medicines for the treatment of depression).
Tell your doctor if you are taking or have taken MAO inhibitors during the last 14 days.
Please keep your doctor informed about all medicines you are taking.

In general, the likelihood of having suicidal thoughts and behaviour is increased in patients suffering from chronic pain. In addition, certain medicines for the treatment of depression (which have an impact on the neurotransmitter system in the brain) may increase this risk, especially at the beginning of treatment. Although tapentadol also affects neurotransmitters, data from human use of tapentadol do not provide evidence for an increased risk.
