General

Adverse reactions other than those attributable to hyperthyroidism due to therapeutic overdose are rare. Excessive doses may result in a hypermetabolic state resembling in every respect the condition of endogenous origin.^[Ref]

If signs and symptoms of overdosage appear, the dosage should be reduced or therapy temporarily discontinued and may be reinstituted at a lower dosage. Normal hypothalamic-pituitary-thyroid axis function has been restored in 6 to 8 weeks after thyroid suppression.^[Ref]
