Mechanism of action
History
Risks
- An allergic reaction occurs when the immune system mistakenly identifies a harmless substance as a dangerous intruder and begins to fight against it. This substance is known as an allergen. When your body reacts to it, a natural chemical called histamine is released. The histamine causes many uncomfortable symptoms, such as a runny nose, sneezing, and itchy eyes.
Medical uses
- Histamine is produced by a type of immune system cell known as a mast cell. The mast cells play a critical role in defending the body from disease. They are the first cells that respond to the presence of foreign substances, such as allergens.
