Chlorothiazide and Breastfeeding
While most research shows that chlorothiazide and breastfeeding is a safe combination, it is possible that the drug may decrease milk production in a breastfeeding woman. Some clinical studies show that chlorothiazide is passed through breast milk in very low or even undetectable amounts. If you are taking chlorothiazide and breastfeeding or thinking of breastfeeding, make sure to talk to your healthcare provider about the possible risks.
Chlorothiazide (Diuril®) is passed through breast milk. Because of the potentially serious side effects that could occur in the nursing infant, the manufacturer of chlorothiazide recommends using the drug with caution while breastfeeding. Therefore, if you are breastfeeding or thinking of breastfeeding, make sure to let your healthcare provider know.
Research suggests that chlorothiazide is passed through breast milk in very low (or even undetectable) amounts. Most sources consider chlorothiazide to be compatible with breastfeeding. However, diuretics (including chlorothiazide) have the potential to decrease your milk production. If you are taking chlorothiazide while breastfeeding, it is important to make sure your milk production is adequate.
You should talk with your healthcare provider about chlorothiazide and breastfeeding. This is because everyone's situation is different, and your healthcare provider understands your situation best. Based on what you want and expect (as well as your current health situation), you and your healthcare provider can make a shared decision about chlorothiazide and breastfeeding in your particular situation.
