Hypersensitivity reactions are common in patients receiving chemotherapy. Hypersensitivity reactions range from a mild localized skin reaction to severe anaphylaxis. Clinicians giving cytotoxic drugs that are associated with hypersensitivity reactions should know the symptoms of a reaction so they can anticipate symptoms and manage them quickly.
When a patient develops a hypersensitivity reaction to a chemotherapeutic agent, the drug is usually stopped. The decision to use the drug again depends on the severity of the reaction, the treatment plan, and the availability of alternative drugs.
