SPECIAL PRECAUTIONS FOR USE
Special precautions for safe use in the target species:
A sudden increase in demand for oxygen delivery to peripheral tissues,
plus the chronotropic effects of
levothyroxine sodium, may place undue stress on a poorly functioning
heart, causing decompensation
and signs of congestive heart failure. Hypothyroid animals with
concurrent hypoadrenocorticism have
a decreased ability to metabolise levothyroxine sodium and therefore
an increased risk of
thyrotoxicosis. These animals should be stabilised with glucocorticoid
and mineralocorticoid treatment
prior to treatment with levothyroxine sodium to avoid precipitating a
hypoadrenocortical crisis. After
this, thyroid tests should be repeated, then gradual introduction of
levothyroxine is recommended
(starting with 25% of the normal dose and increasing by 25% increments
every fortnight until optimal
stabilisation is achieved). Gradual introduction of therapy is also
recommended for anima
