Hypersensitivity Reactions

Hypersensitivity reactions are known as over-reaction of the immune system towards antigen, which does not trigger an immune response. It often results in an allergic reaction when a person's immune system becomes hypersensitive to certain substances such as foods, pollen, medications, or bee venom. Taking antihistamines can help to treat the symptoms.
