Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Carbonic anhydrase inhibitor diuretic used in the treatment of glaucoma and also intracranial hypertension and in certain epilepsies. Oral administration one to four times a day.

It is excreted in breast milk in a clinically insignificant amount and no problems have been observed in infants whose mothers took it in doses up to 1,500 mg (1.5 g) daily. (Ibrahim 2019, Söderman 1984).

The plasma levels of these infants were very low. (Söderman 1984)

Various expert authors consider the use of this medication safe during breastfeeding (Hale, LactMed, Bumen 2020, Belkin 2020, Briggs 2015, Schaefer 2015, Chen 2010). American Academy of Pediatrics: medication usually compatible with breastfeeding (AAP 2001). WHO list of essential medicines: compatible with breastfeeding. (WHO/UNICEF 2002)


We do not have alternatives for Ацетазоламид since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
