monitoring whilst taking antithyroid drugs

Last reviewed 01/2018

The CSM and MCA have made the following recommendations:

  • patients taking antithyroid drugs should be asked to report symptoms suggestive of infection particularly sore throat

  • if there is clinical evidence of infection then a FBC should be performed

  • if there is clinical or laboratory evidence of neutropenia then the antithyroid drug should be stopped

  • routine FBC monitoring is not indicated (1)
