breathing, swelling of the eyelids, face or lips, or rash or itching, which may cover your whole body.
Another serious side effect is a condition where you breathe more slowly or weakly than expected
(rare). It mostly occurs in elderly and weak patients.
If you are affected by these important side effects contact a doctor immediately.
Other side effects that may occur:
Very common (affects more than 1 in 10 patients)
feeling sick (nausea)
dizziness, drowsiness, headache.

sleep problem, tiredness or exhaustion (fatigue), feeling of weakness, trembling, muscle twitches,
shortness of breath

feeling hot (flushing), increased sweating, feeling of body temperature change, dry areas like
nostrils, mouth, lips, eyelids, ears, genitals and anus

chronic pain. In addition, certain medicines for the treatment of depression (which have an impact on the
Page 6 of 7
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.
If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed
in this leaflet.
