If you stop taking Yantil
If you interrupt or stop treatment too soon, your pain is likely to return. If you wish to stop treatment, please
tell your doctor first before stopping treatment.
Generally there will be no withdrawal effects when treatment is stopped. However, on uncommon occasions,

 watery eyes, runny nose, increase in size of the pupils in the eyes (dilated pupils)

tablets, he/she will tell you how to do this. This may include a gradual reduction of the dose.

Like all medicines, Yantil can cause side effects, although not everybody gets them.

Important side effects or symptoms to look out for and what to do if you are affected:
 This medicine may cause allergic reactions (rare). Symptoms may be wheeziness, difficulty
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
(uncommon). 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), being sick (vomiting)
 dizziness, drowsiness, headache.

Common (affects less than 1 in 10 patients)
 decreased appetite, constipation, diarrhoea, indigestion
 anxiety, confusion, hearing, seeing or sensing things that are not really there (hallucinations), sleep
problem, abnormal dreams
 trembling, feeling hot (flushing), dry mouth
 itching, increased sweating, rash
 muscle cramps, feeling of weakness, tiredness or exhaustion (fatigue), feeling of body temperature

Uncommon (affects less than 1 in 100 patients)
 feeling depressed, very happy (euphoria), nervous, restless, or excitable (agitated), low awareness of
time, place or identity (disorientation)
 lack of attention, forgetfulness, almost fainting, sedation, uncoordinated movements, muscle
twitches, difficulty in speaking
 numbness, abnormal sensations of the skin (e.g. tingling, prickling)
 abnormal vision
 faster heart beat, decreased blood pressure, less oxygen in the blood, shortness of breath
 stomach discomfort
 skin reactions (hives)
 feeling of heaviness
 delay in passing urine, passing urine more often than usual
 drug withdrawal effects (see ‘If you stop taking Yantil’)
 water retention (oedema)

Rare (affects less than 1 in 1,000 patients)
 epileptic fits
 thinking abnormal, impaired consciousness, uncoordinated movements, slower heart beat
 delayed emptying of the stomach (impaired gastric emptying).
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.
If any of the side effects gets serious, or if you notice any side effects not listed in this leaflet, please tell your
doctor or pharmacist.
