Approximately 20 mcg/day may be sufficient for infants a few months of age while children 1 year of age may require 50 mcg/day. Children above 3 years may require the full adult dose.

    IV Only Myxedema coma, precoma.

    Adults, initial: 25-50 mcg. Base subsequent doses on continuous monitoring of client's clinical status and response. Doses should be given at least 4 hr, and no more than 12 hr, apart. Total daily doses of 65 mcg in initial days of therapy are associated with a lower incidence of mortality. In cases of known CV disease, give an initial dose of 10-20 mcg.
