Precautions
Patients w/ serious underlying conditions receiving multiple concomitant medications w/ anidulafungin may experience hepatic abnormalities e.g. hepatitis, hepatic dysfunction or worsening hepatic failure. Pregnancy and lactation.
Lactation
There are no data on presence of drug in human milk, effects on breastfed infant or on milk production; drug was found in milk of lactating rats; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from therapy or from underlying maternal condition
Pregnancy-Lactation
Pregnancy
Based on findings from animal studies, therapy can cause fetal harm when administered to a pregnant woman; there are no available human data on use in pregnant women to inform a drug-associated risk of adverse developmental outcomes
