Type I hypersensitivity reactions are IgE-allergy mediated and includes allergic reactions such as anaphylaxis. Type I hypersensitivity reactions occur suddenly after exposure. Common triggers are nuts, bee stings, latex and certain medications e.g. penicillins. Patients should be monitored for potential biphasic reactions. It is also important to distinguish these from non-IgE-mediated anaphylactoid reactions.
