Treatment of Postpartum Thyroiditis with Symptomatic Hypothyroidism, While Breastfeeding, or Attempting Pregnancy

The hypothyroid phase of postpartum thyroiditis does not always require treatment — but certain clinical situations clearly call for intervention. When a woman is symptomatic, currently breastfeeding, or actively trying to conceive, a structured therapeutic approach is indicated.

In women with significant symptoms, those currently lactating or women who are actively attempting pregnancy, treatment should be started.

LT4 should be considered for women with symptomatic hypothyroidism due to PPT.

LT4 should also be started in hypothyroid women who are attempting pregnancy or who are breastfeeding.

LT4 treatment should be considered during the hypothyroid phase of PPT if the patient is mildly symptomatic, or recommended if the patient is considering another conception.

If LT4 is initiated for PPT, discontinuation of therapy should be attempted after 12 months.

Guiding principles are to maintain a euthyroid state in women who are attempting pregnancy or pregnant.
