Hypersensitivity Reactions: What Nurses Need to Know.

 

A hypersensitivity reaction (HSR) is an exaggerated immune response to an antigen which results in local tissue injury and may include life-threatening systemic effects. The most extreme form of HSR is anaphylaxis or anaphylactoid reactions, a life-threatening emergency. Common antigens eliciting HSRs include foods such as peanuts and shellfish, environmental antigens such as natural rubber latex, venoms such as those from bee stings and fire ants, and medications such as antibiotics, monoclonal anti-bodies and chemotherapy.
