Hypersensitivity.

Caspofungin, a semisynthetic echinocandin antifungal, shows activity against Aspergillus and Candida species. It inhibits the synthesis of β-1,3-D-glucan, an essential component of the fungal cell wall that is not present in mammalian cells.

Anaphylaxis reported, discontinue and administer appropriate treatment; possible histamine-mediated adverse reactions, including rash, facial swelling, angioedema, pruritus, sensation of warmth or bronchospasm Hepatic impairment. Pregnancy and lactation. Monitoring Parameters Monitor hepatic function.

Pregnancy There are insufficient human data to establish whether there is a drug-associated risk for major birth defects, miscarriage, or adverse maternal or fetal outcomes in pregnant women Animal data In animal studies, drug caused embryofetal toxicity, including increased resorptions, increased peri-implantation loss, and incomplete ossification at multiple fetal sites when administered intravenously to pregnant rats and rabbits during organogenesis at doses up to 0.8 and 2 times the clinical dose, respectively; advise patients of potential risk to fetus; estimated background risk of major birth defects and miscarriage for indicated population is unknown; all pregnancies have a background risk of birth defect, loss, or other adverse outcomes Lactation There are no data on presence of drug in human milk, effects on breast-fed child, or on milk production Drug was found in milk of lactating, drug-treated rats; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for drug and any potential adverse effects on breastfed child from drug or from underlying maternal condition

Reduced plasma concentration w/ rifampicin and other CYP enzyme inducers. May increase hepatic enzymes w/ ciclosporin. May decrease blood concentration of tacrolimus.
