Low Risk

Possibly safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.

An antiviral used in the prophylaxis of influenza A.

At the date of the last update we did not find any published data on its excretion in breast milk.

Its large volume of distribution makes it unlikely that milk will pass through in significant amounts.

Possible side effects are rare and mild.

Its use is authorized for children from one year of age.

ntil 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.

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.

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.
