Drug Levels and Effects

Summary of Use during Lactation

No information is available on cinacalcet during breastfeeding. However, several newborn infants with disorders of calcium metabolism have been safely treated with cinacalcet.[1] Cinacalcet levels in milk are unlikely to be as high as the doses used in these case. If cinacalcet is required by the mother, it is not a reason to discontinue breastfeeding. Until more data are available, cinacalcet should only be used with careful infant monitoring during breastfeeding.
