BREASTFEEDING
- Pivmecillinam was given orally at doses up to 582 mg/kg/day and mecillinam was
given subcutaneously at doses up to 450 mg/kg/day (approximately 10.2-fold and
7.9-fold higher than the maximum recommended daily human dose of PIVYA, based on
body surface area, respectively). 8.2 Lactation Risk Summary There are
insufficient data to exclude the presence of mecillinam in human milk.
