How does Felimazole Work?

As an anti-thyroid drug, Felimazole works by blocking the production of thyroid hormones to stabilise the symptoms of hyperthyroidism. The active ingredients in Felimazole are Methimazole and Thiamazole, which work to restrict the body's use of iodine, in turn preventing the formation of the thyroid hormone.

It is important to note that Felizamole is not a cure for hyperthyroidism but a treatment intended to prevent and stabilise the symptoms.

Can Felimazole Be Crushed?

Do not break or crush Felimazole tablets and wear gloves when handling.
