For the treatment of feline hyperthyroidism.
GIVING FELIMAZOLE® TO YOUR CAT
What is Felimazole® and how does it work?
Felimazole® is the first licensed medical treatment for feline hyperthyroidism. It contains the anti-thyroid drug methimazole, which reduces the production of T4 and T3 within the thyroid gland.
How do I give Felimazole® to my cat?
Felimazole® tablets need to be given either once or twice daily. Follow the instructions given by your veterinary surgeon. Felimazole® tablets are best given directly to your cat, but the small, sugar-coated tablets can also be hidden whole in the food.
What should I do if I forget to give a tablet?
Speak to your veterinary surgeon. DO NOT give a double dose next time. If your cat is due to have a monitoring blood test within a couple of days of missing a tablet, MAKE SURE YOU LET YOUR VETERINARY SURGEON KNOW as it could affect the blood results.
How long will my cat require treatment?
To maintain normal T4 and T3 concentrations in the blood your cat will need to be dosed with Felimazole every day for the rest of their life.
Will I need to revisit my vet?
Yes. It is important that your cat revisits your vet for assessment and monitoring tests. These are recommended at 3, 6, 10 and 20 weeks after starting treatment and thereafter every 3 months.
Does Felimazole® have any side-effects?
Side-effects most commonly occur within the first 3 months of therapy. They are generally mild and include inappetance, vomiting and lethargy. More serious side-effects are possible so if your cat becomes unwell at any time while on Felimazole® therapy, stop treatment and consult your veterinary surgeon as soon as possible.
