Adverse events with the drug are rare and involve mainly the gastrointestinal and central nervous systems. Skin inflammation, urticaria, pruritus, alopecia, and dry skin have been reported in 0.5-1.5 % of patients. We report a case of a 56-year-old man with peptic ulcers who developed periorbital edema, edema of the skin, generalized pruritis and urticaria, a swollen tonque, increase sweating and loss of conciousness. These findings suggest that the chemically related lansoprazole can, as a group, cause anaphylactic reactions; however, the rate is comparatively low. Since anaphylaxis is a potentially serious reaction, more precise information is needed regarding its frequency, and healthcare professionals need to be aware of this possibility when prescribing these agents.trinfo:eu-repo/semantics/closedAccessAnaphylactic Reactions; LansoprazoleArticle3532092112-s2.0-34548253542N/A
