Liver Flukes

Hi I am totally new to this forum but have loved reading thru all the entries. I am hoping someone can help me... I have liver flukes and I ordered some Triciabendazole by the name of Lexsays through Dr Cheiu. Has anyone else used this particular product. Dr Cheiu said that Egaten is not made anyone? I only ordered one packet as its so expensive to get to New Zealand, but think I need more.
