كوينيدين

Compatible

Safe product and/or breastfeeding is the best option.

Quinidine is a D-isomer of quinine found in the bark of the Cinchona tree and similar plant species. It is a class Ia antiarrhythmic with antimuscarinic and alpha-adrenergic receptor blocking properties.  It is used in the treatment of supraventricular and ventricular arrhythmias, including atrial fibrillation and atrial flutter. Can be used as an alternative to quinine in the treatment of malaria when quinine is not available. Oral administration 3-4 times daily.

Excreted in breast milk in clinically insignificant amount: a single study in one mother. (Hill 1979)

Milk production should be monitored, as its antimuscarinic properties may inhibit prolactin secretion.

Expert authors consider that the use of this medication during lactation is probably compatible. (Hale, Tan 2001)

American Academy of Pediatrics: medication usually compatible with breastfeeding. (AAP 2001)

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.
