  • Anaphylactic reactions, including shock, reported; discontinue and initiate appropriate treatment if this occurs

Pregnancy and Lactation

  • Based on findings from animal studies, therapy can cause fetal harm when administered to pregnant females; there is no available human data on use in pregnant females to inform a drug-associated risk of adverse developmental outcomes. 
  • There are no data on presence of drug in human milk, effects on breastfed infant or on milk production
  • Drug found in milk of lactating rats; when a drug is present in animal milk, it is likely that the drug will be present in human milk
