Hi,
The known side effects of eslizen are - Dizziness, somnolance, headache, nausea, vomiting and
hyponatremia.
As for levera these are the known side effects - Somnolence, asthenia, ataxia, hairless,
depression, dizziness, vertigo, emotional instability, hostility,
nervousness, ataxia,tremor, amnesia, headache, nausea,
dyspepsia, diarrhoea, anorexia, rash, diplopia.
As such it could be that the tremors you are getting are a result of levera, mention this to your doctor when you see him, so that he can change the medication you are taking accordingly.
I hope this helped.
