Бензилпенициллин

Compatible

Safe substance and/or breastfeeding is the best option.

Penicillin. Beta-lactam antibiotic, with bactericidal action. Intramuscular administration. 

Penicillins are excreted in breast milk in clinically insignificant amounts.  (vanWattum 2018, Matheson 1988, Matsuda 1984, Borderon 1975, Knowles 1973, Rozansky 1949, Greene 1946)

No problems have been observed in infants of mothers treated with penicillin, except for occasional transient gastroenteritis due to altered intestinal flora. (Matheson 1988)

When measured, plasma levels in these infants were undetectable or very low. (Matheson 1988)

Penicillin is a broad spectrum antibiotic that is commonly used in Pediatrics and Neonatology with very good tolerance even in premature newborns. 

Expert authors consider the use of the use of penicillin and its derivatives to be safe during breastfeeding. (Hale, LactMed, Briggs 2015, Butler 2014, Rowe 2013, ASGE 2012, Amir 2011, Nahum 2006, Bar-Oz 2003, Niebyl 2003, Fulton 1992, Léophonte 1988)

Eleventh WHO's Model List of Essential Drugs 2002: benzathine benzylpenicillin, benzylpenicillin, phenoxymethylpenicillin and procaine benzylpenicillin are compatible with breastfeeding. (OMS / UNICEF 2002)

Alternatives

We do not have alternatives for Бензилпенициллин 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

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.
