PRODUCT INFORMATION

For the stabilisation of hyperthyroidism in cats.

Felimazole is a prescription-only veterinary medicine containing methimazole, licensed for use in cats. It is indicated for the long-term management of feline hyperthyroidism.

Methimazole acts by inhibiting the synthesis of thyroid hormones, helping to reduce excessive circulating thyroxine (T4) levels associated with hyperthyroidism. Appropriate dosing and regular monitoring are essential to ensure effective and safe treatment, as directed by a veterinary surgeon.

Felimazole Film-Coated Tablets are commonly prescribed for cats requiring ongoing medical management of hyperthyroidism and are intended for long-term use.

Felimazole should only be used under veterinary supervision and supplied against a valid veterinary prescription.

Tablets may be supplied either as individual tablets dispensed from original manufacturer packaging or as full sealed manufacturer packs, depending on the option selected and the veterinary prescription.

Further information, including contraindications and potential side effects, can be found in the product data sheet available here.
