Very Low Risk
Thiazide diuretic with action and uses similar to hydrochlorothiazide. Indicated in the treatment of hypertension and edema secondary to heart failure. Oral administration once-twice a day.
Milk levels of a mother who took 500 mg of chlorothiazide were undetectable or very low, <1 mg / L.(Werthmann 1972)
Despite some older studies, there is no scientific evidence that diuretics reduce breast milk production. (Anderson 2018, Rowe 2013)
Several medical societies, experts and expert consensus, consider the use of this medication safe or probably safe during breastfeeding (Briggs 2015, Hale 2017 p190). American Academy of Pediatrics: Maternal Medication Usually Compatible With Breastfeeding. (AAP 2001)
Long-term treatment with diuretic drugs may compromise the state of hydration of the nursing mother. Must make an adjustment (decrease) of the dose based on the estimated milk production and monitor milk production.
We do not have alternatives for Chlorothiazide since it is relatively safe.
