What is a flare reaction?

A flare reaction is characterized as a localized allergic reaction that occurs along a vein, usually due to the administration of irritating drugs during chemotherapy or other infusions. This reaction is typically marked by symptoms such as redness, swelling, and discomfort at the site of infusion. When chemotherapy drugs are irritating to the tissues, they can cause these localized reactions, and understanding this phenomenon is crucial for managing patient care during treatment.

Identifying flare reactions allows healthcare providers to take appropriate steps to mitigate discomfort, such as adjusting the rate of infusion, using premedications, or changing the route of administration. Knowledge of these reactions is integral in ensuring patient safety and comfort during chemotherapy protocols.
