Hi, My granddaughter is 8 years old the gave her Sulfameth- Trimeth Susp{Grape} for a UTI.. everytime she takes it the taste is so bad, she vomits some of it back up, and then complains of feeling very nauseous for hours after taking it.. does it come in a chewable tablet, or small pill form, or is there a different med she could take? thanks Nana
