immune response resulting from an .
This exaggerated response to an antigen is referred to as
hypersensitivity
.
is the term used to describe the *?unexpected failure*
Anergy of the immune system to respond to the challenge of a
foreign substance (antigen or allergen).

Cutaneous reactions are considered .
non-immunologic
*NOT your immune system responding*
Some , such as contact dermatitis, may appear to be
cutaneous reactions allergic reactions, but they *do not involve the immune

Anaphylaxis is a hypersensitivity reaction involving
IgE-mediated release of histamine, leukotrienes, and oth-
er mediators from already sensitized mast cells and ba-
sophils.
Anaphylaxis is a *type I* hypersensitivity reaction involving
IgE-mediated release of histamine, leukotrienes, and other mediators from
already sensitized mast cells and basophils.
The release of these mediators initiates a systemic chain
histamine, leukotrienes, and other mediators from al- of events that includes symptoms such as angioedema,
ready sensitized mast cells and basophils flushing, pruritus, urticaria, nausea, vomiting, and wheez-
ing.
The onset of the reaction is quick, generally within 1 to 30
Anaphylaxis
minutes.
1-30 anaphylaxis occurs within minutes
reactions are similar in appearance to anaphylaxis but
Anaphylactoid may occur after the first injection of certain drugs and
contrast media.
(1) remove allergen
(2) drug therapy i.e., antihistamines, etc.
Treatment of allergies/allergic reactions:
(3) prophylaxis i.e., prevention, immunotherapy desensi-
tization
is a medical procedure used to temporarily trick your
immune system into tolerating penicillin when no other
suitable antibiotic alternatives exist. It involves starting
Penicillin desensitization
with a minuscule dose of the medication and progressively
increasing it every 15 to 30 minutes until a full therapeutic
dose is successfully delivered. [1, 2, 3]
(1) Alleviate the symptoms with little to no adverse ettects
from medications.
