Pivampicillin is an ester of ampicillin and has similar uses.It is an inactive pro-drug, which is converted during its gastrointestinal absorption to the active ampicillin.
Oral administration 3 or 4 times daily.
Authorized for use in infants.

It is excreted in breast milk in small amounts (Matheson 1988, Branebjerg 1987), much lower than the dose used for newborns and infants.

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).

Ampicillin, the active drug of pivampicillin, is compatible with breastfeeding.

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.
