What is Felimazole?

Licensed in 2002, Felimazole is the original veterinary licensed treatment for feline hyperthyroidism. Available in both oral solution and tablet formulations, Felimazole provides accurate and flexible dosing to suit medically treated patients.

Both formulations of Felimazole are licensed for the stabilisation of hyperthyroidism prior to surgical thyroidectomy and for the long-term treatment of feline hyperthyroidism.

The recommended starting dose for Felimazole is 5 mg per day. Wherever possible, the total daily dose should be divided into two equal doses and administered morning and evening.

Therefore, this means a starting dose of either 0.5 ml of oral solution twice daily or one 2.5 mg Felimazole tablet twice daily (as Felimazole tablets should not be split).

If, for reasons of compliance, once daily dosing is preferable, then this is acceptable, although the twice-daily dose may be more efficacious in the short term.

Dose adjustments should be made in increments of 2.5 mg and the aim should be to achieve the lowest possible dose rate.

In cats that require particularly small dose adjustments, increments of 1.25 mg of thiamazole can be used.

If more than 10 mg per day is required (this equates to 2 ml of the veterinary medicinal product or any combination of Felimazole tablets which reach a total dose of 10 mg) animals should be monitored particularly carefully.

The total daily dose administered should not exceed 20 mg

Available in three different strengths (1.25 mg, 2.5 mg and 5 mg) allowing you to precisely tailor the dose
- In particular, the 1.25 mg tablets are intended for use in cats that require particularly small doses of thiamazole, and to assist with dosage adjustments
