Dicloxacillin

Very Low Risk for breastfeeding


Safe. Compatible.
Minimal risk for breastfeeding and infant.

It is a staphylococcal penicillinase resistant penicillin.
Oral or intravenous administration every 6 hours.

Like most penicillin-type antibiotics (Nau 1987), excretion into breast milk is clinically non-significant (Muysson 2020, Matsuda 1984). No harmful effects are expected nor reported in infants whose mothers were taking it.

Widely used for treatment of Mastitis since it has an effective activity against staphylococci resistant to benzylpenicillin (Amir 2014 y 2011, Spencer 2008, Nordeng 2003, Bodley 2000).

The possibility of transient gastroenteritis due to alteration of the intestinal flora in infants whose mothers take antibiotics should be taken into account (Briggs 2017, Ito 1993).

Alternatives

We do not have alternatives for Dicloxacillin since it is relatively safe.
