Question

____ drugs quickly nullify the symptoms of allergy.

Answer 1

Allergy:

1. An allergy is an exaggerated reaction of the body's immune system to a particular food or substance which is generally harmless to most people.
2. Allergy can also said to be hypersensitivity of the body's immune system to a specific substance.
3. Generally the first exposure to an allergen does not cause allergy and helps in the formation of antibodies only. But the second or subsequent exposures cause strong allergic reactions.
4. Anti-histamine drugs quickly reduce or nullify the symptoms of allergy.

Final answer: Anti-histamine drugs quickly nullify the symptoms of allergy.
