An allergic reaction is the body’s way of responding to an
“invader”. This triggers the immune system of the body which is helpful
in fighting bacteria and toxins. The substance that causes an allergic
reaction is called an allergen. Dust, pollen, plants, medication, and
certain types of food are all example of allergens. The reaction could
also be in one of many forms such as a small skin rash, itchy eyes, and
even all over the body. It is very rare that deaths occur as a result
of an allergic reaction. Penicillin is one of the medications which is
known to cause allergies.
Allergies could also run in the
family and be passed on from parent to child. Most people are aware of
their allergy triggers and the corresponding allergic reaction. The
best thing to do is to stay away from any of the substances that are
known to cause allergies. Individuals with certain medical conditions
may also be prone to some allergies; for instance, those with asthma or
frequent infections of the nasal sinuses, ears or respiratory tract. A
person with sensitive skin might also develop an allergic reaction to
certain things. Different medications are prescribed depending upon the
type of allergy and the kind of allergic reaction it produces.
Long-term
allergies such as hay fever, or reactions to animal dander are
prescribed long-term antihistamines which help control the symptoms
without causing any drowsiness. Most have to be taken only once a day
and their effect is felt the whole day. Nasal sprays are also
prescribed if the nasal symptoms are not relieved by antihistamines.
Allergy shots are also administered to some people who have persistent
symptoms. These shots are usually given in a series over a certain
period of time and the effectiveness of the treatment depends upon the
individual.
