Immune System Reaction

Meaning

An Immune System Reaction, in the context of hormonal health and therapeutics, refers to the body’s complex biological response to a substance, whether it is the active pharmaceutical ingredient (API) or an excipient, that the immune system incorrectly identifies as a foreign or harmful antigen. These reactions range from mild localized inflammation to severe systemic hypersensitivity or anaphylaxis, posing a significant clinical challenge. Understanding the potential for an immune reaction is vital when administering peptide hormones or other complex compounds that may possess immunogenic properties. Clinical surveillance for signs of immune activation is a necessary part of therapeutic monitoring.
