Thiafeline 2.5mg Tablets

Thiafeline 2.5mg Tablets are indicated for the long-term treatment of feline hyperthroidism and for the stabilisation of hyperthyroidism in cats prior to surgical thyroidectomy.

As thiamazole can cause haemoconcentration, cats should always have access to drinking water.

Each tablet contains 2.5mg thiamazole.
