Fenspiride Hydrochloride

Likely Compatibility

Fairly safe. Mild or unlikely adverse effects. Compatible under certain circumstances. Follow-up recommended. Read Commentary.

An oxazolidinone compound with antihistamine, anti-inflammatory and bronchodilatory actions which have not been thoroughly studied.
Indicated in the symptomatic treatment of coughing and expectoration caused by inflammatory bronchial and lung diseases (Medana 2015, Quartulli 1998).

Since the last update we have not found published data on its excretion in breastmilk.

In the absence of knowing the percentage of plasma protein binding, its known pharmacokinetic data (Medana 2015, Montes 1993) (low molecular weight, half-life of more than 12 hours) makes it likely it will transfer to milk in amounts that could be significant and that could reach infant plasma (high oral bioavailability).

Its possible adverse effects are mild and not very frequent (Medana 2015).

Authorized pediatric use from two years of age.

This product has been little studied in humans, with very few bibliographical references and is sold in very few countries.

Until there is more published data on this drug in relation to breastfeeding, safer known alternatives may be preferable, especially during the neonatal period and in case of prematurity.

In 2019, the National Agency (France) for Drug Safety suspended the marketing authorization for Fenspiride due to the risk of QT prolongation (ANSM 2019).

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.
