The Need For Allergy Shots
An allergy
shot contains a very little amount of the
substance that the patient is allergic to, called
an allergen. Treatment carried out through the allergy shots is also
called immunotherapy.
Common allergens consist of mold
and pollen from grasses, ragweed and trees. So,
for instance, if someone is allergic to grass
pollen, a small amount of grass pollen will be
included into the shot. Immunotherapy not only
makes symptoms go away, it can truly help prevent
the amplification of the disease into asthma and
decreases the number of allergies.
Allergy shots help the body fight
with the allergen. When shots of the allergen
are given, the body starts making antibodies into
the allergen. The next time the body has any contact
with the allergen, these antibodies help block
its effect. Because the antibodies block the way,
the body reacts to the allergen; the allergy symptoms
become less severe. After many allergy shots,
the person experiencing the allergy might start
to get relief from the allergy symptoms. This
relief will last for a long duration of time.
Not all people have to be treated
with allergy shots. Allergy shots work very well
for pollen allergies, which are also called allergic
rhinitis or hay fever, eye allergies, bee-sting
allergy and some other drug allergies. In quite
a few people, allergy shots can bring about an
improvement in asthma symptoms.
Usually people get treated through
the use of allergy shots after they have tried
other treatments that have not worked for them.
Other treatments include staying away from allergens
and taking medicines, such as an antihistamine.
Everyone cannot get allergy shots.
Allergy shots may not be good for people especially
if they have severe asthma or heart ailments.
An allergy shot should be taken if the person
having the allergy takes a beta blocker for heart
problems.
Children younger than five years
of age also should not get allergy shots. Allergy
shots should not be given in cases of pregnant
women. But, if someone has been taking allergy
shots and during that time, becomes pregnant,
a doctor should be consulted. He may advise you,
depending on your situation, whether you can continue
taking allergy shots or not.
When the doctor and patient both
decide to have the allergy shots, the doctor will
want to do an allergy test to help determine exactly
what it is that is causing the allergy. An allergy
skin test puts very little amount of allergens
onto the skin to see which ones get a reaction
from the body. Or, a blood test may be decided
to be taken, such as the radioallergosorbent test,
often called RAST, or the ImmunoCap test.
Quite a few allergy shots need to
be taken. The doctor will start giving the shots
once or twice a week. After almost six weeks of
weekly allergy shots, the doctor decides when
the maintenance treatment can be started. Maintenance
shots are given usually just once each month,
throughout the year.
Maintenance shots need to be given
mostly for three to four years. After that, allergy
shots are even stopped in many cases.
Allergy shots are not harmful. They
are usually safe. But because allergy shots contain
tiny amounts of an allergen a person might have
an allergic reaction to the shot itself. One common
response to allergy shots is swelling and inflammation
at the place where the shot is given.
Some people can also have severe,
shock-like responses to an allergy shot. This
kind of reaction is called anaphylaxis. Anaphylaxis
is a reaction that is rare but very severe.
If the shots are taken according
to the schedule, that is, every week or every
month, it is less likely that such a reaction
will occur.
In case there is a bad reaction,
a stay at the office for about twenty minutes
every time a shot is given will be considered
by the doctor. That way, even if there is a reaction,
the doctor will be able to do something right
away to stop the reaction to the shot.
Patients are mostly worried about
how long it will take after the shots that the
allergy will start getting better. It normally
takes six months or a longer duration of time
before the person experiencing the allergy starts
feeling good and notice relief from the allergy
symptoms.
If, even after this time, the allergy
symptoms do not get better, the doctor can be
asked to use any other kind of treatment for the
allergies.
