Felimazole Monitor Plus

Thyroxine (T4), Alkaline Phosphatase (AP), Alanine aminotransferase (ALT), Urea, Creatinine and Phosphorus.

Felimazole® monitor plus includes the measurement of thyroxine (T4) but also includes specific biochemistry tests.

Alkaline phosphatase (AP)
Alanine aminotransferase (ALT)

Both AP and ALT are commonly elevated in untreated hyperthyroidism. By measuring these enzymes, it is possible to assess improvements due to therapy and to identify any underlying primary hepatic disease.


The measurement of urea, creatinine and phosphorus will assist in the identification of renal disease. The “unmasking” of previously subclinical renal insufficiency is not uncommon following all forms of anti-thyroid therapy. By monitoring these parameters, it is possible to better navigate the balance between hyperthyroidism and renal insufficiency in case this situation should arise.
