Î Breastfed children of women who are treated with antithyroid drugs
should be monitored for appropriate growth and development during
routine pediatric health and wellness evaluations. Routine assessment
of serum thyroid function in the child is NOT recommended. (W-M)
Î All breastfeeding women should ingest approximately 250 mcg of
dietary iodine daily. (S-H)
Î Breastfeeding women should supplement their diet with a daily
oral supplement that contains 150 mcg of iodine. This is optimally
delivered in the form of potassium iodide (present in a multivitamin)
because kelp and other forms of seaweed do not provide a consistent
delivery of daily iodine. (S-M)
Î In severely iodine deficient, low-resource regions, where universal
salt iodization is lacking and daily supplementation is not feasible,
lactating women should receive one dose of 400 mg iodine as oral
iodized oil soon after delivery. (S-H)
Î As is the case during pregnancy, sustained iodine intake while
breastfeeding that exceeds 500–1100 mcg daily should be avoided
due to concerns about the potential for inducing hypothyroidism in
the infant. (S-M)
