I am a acute vertigo patient since 2002, after taking Vertin 8mg regularly from 2007 and vertin 16 mg from November 2012 I feel normal in case of vertigo but since last three months I feel tasteless and to some extent vomiting feeling and loss of appetite. My birulibin is varying from 1.2 to 1.7. If I stop vertin then after two days again I feel vertigo problem & dizziness. MD medicine Specialist has recommended for continuing vertin 16mg twice a day with other liver medicine etc. Now my question is that how long I can take vertin 16mg or 8mg as my age is now 53.
