Peginterferon alfa

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

It is used in the treatment of leukemia, and, hepatitis B and C.

Breast milk contains several interferon-like substances which contribute to its anti-viral action.

High molecular weight of interferon accounts for its small secretion into breast milk. A minimal gastrointestinal absorption is commonly accepted.

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.
