Is Etamsylate compatible with breastfeeding? Do we have alternatives for Etamsylate?


January 24, 2017 (Low Risk)

Hemostatic drug which has a possible protective effect on the capillary wall along with correction of altered platelet adhesion.
It is used in Menometrorrhagia (Lethaby 2013), prophylaxis on surgical wounds and neonatal intraventricular hemorrhage without a solid evidence of its effictiveness (Hunt 2010, Kuperman 2015).
It is orally, intramuscularly and intravenously administered.

At latest update relevant published data on excretion into breast milk were not found.

Its high capacity of binding to plasma proteins makes it unlikely a excretion into breast milk.

Due to low frequency and mildness of eventual side effects and/or absence of interference with coagulation mechanisms, seems unlikely this product would affect breastfeeding or the infant.


We do not have alternatives for Etamsylate.
