My husband has been on 50mg Sutent since March of 2008. In early September of 2010 he started to experience side affects after he ended his treatment cycle. For 2-3 days he will vomit all day if he eats anything at all - even water, and then he is terrible dizzy and unable to walk with out balance assitance for up to 4 days. Our doctor dismissed the idea to see an inner ear doctor but gave no additional guidance. Any ideas or remedies?
