PRODUCT INFORMATION

Important Supply Update: There is currently an ongoing manufacturing delay affecting Felimazole 5mg/ml Oral Solution 30ml bottles, and availability may be limited.

Please speak with your veterinary surgeon if you may require an alternative prescription or treatment plan.

For the stabilisation of hyperthyroidism in cats.

Felimazole Oral Solution is a prescription-only veterinary medicine containing methimazole, licensed for use in cats. It provides an alternative formulation for cats that are unable to tolerate tablets or where flexible dosing is required.

Methimazole works by inhibiting thyroid hormone synthesis, helping to reduce elevated thyroxine (T4) levels associated with feline hyperthyroidism. Dose adjustments and regular monitoring are essential, as directed by a veterinary surgeon.

Felimazole Oral Solution is intended for long-term administration where appropriate and should be used under veterinary supervision.

Felimazole should only be supplied against a valid veterinary prescription.

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