Abstract
Triptorelin is a synthetic gonadotropin-releasing hormone agonist for the treatment of precocious puberty in children. Among the triptorelin side effects, drug hypersensitivity reactions, including anaphylaxis, can rarely occur, mostly after repeated exposure to the drug. We present a first case of an 8-year-old girl with central precocious puberty who developed anaphylaxis to the first injection of decapeptyl depot, which contains triptorelin acetate (D,L lactide coglycolide), dextran 70, and polysorbate 80. She showed 2 positive reactions in an intradermal test to decapeptyl depot, suggesting that it is an IgE-mediated reaction to one of its components. Considering this was the first exposure to triptorelin, it might be a reaction to polysorbate. As there are many therapeutic products containing polysorbate which can cross-react with polyethylene glycols, physicians should pay attention to immediate reactions to drugs containing polysorbate.
