Anaphylaxis to artesunate?

Artesunate, an artemissin derivative is a highly efficacious and relatively safe antimalarial agent. Common adverse reactions to artemissin derivatives are nausea, vomiting, anorexia and dizziness. More serious but less-frequent toxic effects of artesunate use are neutropenia, anemia, hemolysis, elevated liver enzymes and severe allergic reactions. However, anaphylactic reaction to artesunate is a rare entity. Here, we report a case of anaphylaxis to parenteral artesunate and its successful management in a female patient to whom intravenous artesunate was administered during surgery under general anesthesia.
