gland becomes enlarged causing a swelling in the front of the neck.

Posology
ADULTS
The treatment of any thyroid disorder should be determined on an
individual basis, taking account of clinical response,
biochemical tests and regular monitoring.
The individual daily dose should be determined on the basis of
laboratory tests and clinical examinations. As a number of
patients show elevated concentrations of T4 and fT4, basal serum
concentration of thyroid-stimulating hormone provides a
more reliable basis for following treatment course.
Patients switching from the oral solution to the tablet form or from
the tablet form to the oral solution should be monitored
closely.
Levothyroxine is best taken as a single dose on an empty stomach,
usually before breakfast.
Hypothyroidism (congenital or acquired)
Adults, children over 12 years
Initial dose:
50 - 100 micrograms daily
before breakfast.
