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.

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.
Felimazole® is a prescription only medicine (POM-V) and should only be used under the advice of a qualified veterinary surgeon.
