Propafenone Hydrochloride

Compatible

Safe substance and/or breastfeeding is the best option.

Propafenone is a class Ic antiarrhythmic with some negative inotropic and beta-adrenoceptor blocking activity.
It is used in the management of supraventricular and ventricular arrhythmias.
Oral administration three times a day.

It is excreted in breast milk in clinically insignificant amounts (Wakaumi 2005, Libaron 1991).

In people who are slow metabolisers, the elimination half-life can be 10 to 32 hours.

Expert authors consider the use of the medication to be probably compatible during breastfeeding (Hale 2019, Briggs 2017).

Alternatives

We do not have alternatives for Propafenone Hydrochloride 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
