Patients with mastocytosis have an increased risk for mast cell activation events including anaphylaxis when exposed to certain drugs and Hymenoptera venom. Hypotension and cardiovascular collapse without skin or other systemic manifestations can occur after Hymenoptera stings, during the perioperative period, and after exposure to nonsteroidal ntiinflammatory drugs, opioids, and other mast cell activating medications, including vancomycin and quinolones. This chapter reviews the epidemiology, mechanisms, diagnosis, management, and treatment options for Hymenoptera venom and drug-induced reactions in patients with mastocytosis.
