Safe substance and/or breastfeeding is the best option.

Coumarin-type anticoagulant drug vitamin K antagonist with actions similar to those of warfarin used for the treatment and prophylaxis of thromboembolic disorders. It works by depressing the hepatic synthesis of vitamin K-dependent coagulation factors.Oral administration. 

Its high plasma protein-binding capacity would explain the very low excretion observed into breast milk. (Houwert-de Jong 1981, Nava 2004)

No clinical side-effects and/or blood test disarrangements were observed in infants whose mothers were treated with acenocoumarol. (Houwert-de Jong 1981, Fondevila 1989)

Several medical societies and experts authors consider the use of this medication to be safe or very probably safe during breastfeeding. (Bates 2018, 2012 & 1997, Middeldorp 2011, Clark 2000, Olthof 1993)

Alternatives

We do not have alternatives for C19H15NO6 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.
