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.

side effects not listed in this leaflet. You can also report side effects directly via the Yellow
