Q. My cat was recently diagnosed with hypathyroid.He was put on methimazole and after about 2.5 wks he stopped eating. I'm reading this is not agreat med

A. This medication can be very effective in controlling the symptoms of hyperthyroidism by lowering the thyroid hormone level. However, it commonly causes gastrointestinal side effects such as inappetance, nausea, vomiting and diarrhea. The medication does come in an enteric coated tablet formulation which can cause less GI issues. You can also have the medication compounded into a transdermal gel or cream which is applied to the inner portion of the ear and the medication is absorbed through the blood stream instead of being ingested, thereby reducing GI upset. I would discuss your issues with your vet and go over other forms of the medication. There is also the possibility of surgically removing the enlarged thyroid which eliminates the need for medication. The best treatment available for this condition is radioactive iodine treatment. If your veterinarian does not offer this service, which most do not, they may be able to refer you to a facility that does.
