Abstract

Omeprazole does not usually cause severe adverse reactions in most cases, especially during short-term use. Anaphylactoid reactions may be secondary to medications. We present the case of a 39-year-old male patient who developed an acute coronary syndrome a few minutes after the intravenous administration of omeprazole. The diagnosis of Kounis syndrome was made considering the association between anaphylactic shock and cardiovascular involvement. This case is presented because, despite being a known syndrome, its incidence is very low, which makes diagnosis difficult; its occurrence as an adverse drug reaction should always be considered by the attending physician.
