Explanation:

An anaphylactic reaction also known as anaphylaxis can be defined as a severe short-term allergic reaction that usually occurs within seconds or minutes after being exposed to an allergen.

Basically, an anaphylactic reaction is potentially life threatening i.e it is capable of causing death to patients and as such a medical diagnosis is required and it must be treated by a medical professional (expert) immediately after exposure to an allergen.

Hence, an anaphylactic reaction occurs because of an antigen-antibody interaction.

An epinephrine (adrenaline) may be quickly administered (given) to the patient by the medical professional.

Some of the symptoms of an anaphylactic reaction are;

I. Running nose and sneezing.

II. Skin rash.
