Q. my vet gave my 6lb 10mo. old cat 250mg of terbinafine to treat ringworm a week ago now my cat will not eat very much, is the doseage to much for him.

A. Research has shown that cats can get up to 40mg of terbinafine twice daily for ringworm without being overdosed, so that would approximately be the dosage your cat is receiving. However research also found out that 40mg/kg once daily is also sufficient. ( http://www.ncbi.nlm.nih.gov/pubmed/11557156 ). If you think that your kitty is not eating much because it may be a side effect from the medication, you should go back to your vet and discuss reducing the dose. Do not reduce the dose without consulting with your veterinarian,
