Felimazole is a medication for cats which is used to treat hyperthyroidism. This is a condition which affects mainly older animals and relates to the over-activity of the thyroid gland. The medication controls the amount of hormones released by the thyroid gland.
A cat that has an overactive thyroid may suffer a number of other medical problems as well, such as high blood pressure, a fast heart rate, extreme weight loss and eye problems. If the condition is not treated then the cat may suffer problems with the heart or other organs, blindness and a reduced life expectancy.
Felimazole are small tablets which are sugar coated. They are intended to be administered via the mouth, though this is sometimes hard to do with cats so they can also be added to food.
Most cats will not suffer any side effects from Felimazole and will improve a great deal while taking it. A minority of cats have suffered some side effects such as itchiness around the head and neck which can lead to skin damage from excessive scratching. If more serious side effects are suspected then the cat should be examined by a vet. Those handling the drug should always wash their hands after doing so.
