Allergies: Should I Take Allergy Shots?Skip to the navigationYou may want to have a say in this decision, or you may simply want to follow your doctor's recommendation. Either way, this information will help you understand what your choices are so that you can talk to your doctor about them. Allergies: Should I Take Allergy Shots?Get the factsYour options- Don't get allergy shots. Instead, keep taking
medicine to control your symptoms, and try to get rid of or avoid the
allergen.
- Get allergy shots along with taking medicine to control your
symptoms.
Key points to remember- There is no cure for
allergic rhinitis or
allergic asthma. But allergy shots may provide
long-term relief of symptoms.
- Allergy shots will probably help you. They are effective for
most people and can reduce symptoms if you are allergic to pollens,
animal dander,
dust mites, mold, or cockroaches.footnote 1 Allergy shots may prevent children with allergic rhinitis
from getting asthma.footnote 1
- You need to take allergy shots for 3 to 5 years.
- You cannot be sure how long the shots will be effective after
you stop getting them. For allergies to some grasses, shots have been effective
for 3 or 4 years.footnote 1
- If you
have
coronary artery disease, are using
beta-blockers, are pregnant, are not able to
communicate how the shots are working, or have an
impaired immune system, allergy shots may not be
recommended.
- Children may use allergy shots if they have persistent
asthma made worse by allergens.
- Children younger than 2 should not have
allergy shots.
- Children ages 3 to 4 may find it hard to have to
get many shots over a long period of time. Talk with your
doctor.
- Your child's asthma needs to be well controlled before he
or she gets allergy shots.
FAQs Allergic rhinitis (often called hay fever) occurs when your
immune system overreacts to particles in the air that
you breathe-you are allergic to them. Your immune system attacks the particles,
causing symptoms such as sneezing and a runny nose. The particles are called
allergens, which simply means that they can cause an
allergic reaction.
Asthma is a long-lasting condition that causes
wheezing, trouble breathing, tightness in the chest, and coughing. When
allergens such as pollens,
dust mites,
animal dander, cockroaches, and
mold make your
symptoms worse, it is known as
allergic asthma. Allergic rhinitis can affect your health if you don't
treat it. You may have problems such as sinus
infections, plugged ears or
ear infections, and
sinusitis. If you don't control allergic
asthma, it increases your risk of problems from lung and airway infections,
such as
bronchitis and
pneumonia. When you get immunotherapy in the form of allergy shots, your
allergist or doctor injects small doses of substances
that you are allergic to (allergens) under your skin. Over time,
this decreases your reaction to the allergen and may reduce the symptoms of
allergic rhinitis. Allergy shots are available for
allergies to: - Pollen (ragweed, grasses,
trees).
-
Dust mites and
cockroaches.
-
Animal dander (dog and
cat).
-
Mold (fungus).
Sublingual immunotherapy may be another way to treat certain pollen allergies. Instead of getting shots, you dissolve a tablet under your tongue daily. Each tablet has a small amount of allergen in it. This treatment, like allergy shots, helps your body "get used to" the allergen, so your body reacts less to it over time. Talk to your doctor if you have a pollen allergy and you want to know more about this treatment. - You have allergic rhinitis and you have tried medicine and have avoided
allergens, but you still have severe symptoms.
- You have allergic rhinitis and you have tried
medicine, but the side effects bother you.
- You have allergic asthma, your symptoms last most of the year, and you don't get relief if you take medicines or avoid allergens.
- You have another health problem, such as
coronary artery disease (CAD), that puts you at increased risk for a
severe reaction to the shots.
- Your child with allergies is younger
than 5.
- You are pregnant. Pregnant women who are already getting
allergy shots may keep getting them. But doctors don't recommend starting
allergy shots during pregnancy.

I bought my
daughter, Tina, a cat for her birthday. A month or so later, I developed
allergy symptoms that I have never had before: sneezing; puffy, irritated eyes;
and feeling tired. I thought maybe I was allergic to a detergent or soap, but
my doctor did some tests, and it turns out I am allergic to the cat. I know it
would break my daughter's heart to have to find a new home for the cat, and I
have gotten attached to it, too. I decided to try getting the allergy shots and
do what I can to keep the cat hair and dander out of my bedroom. For as long as I can remember, I have had
bad hay fever. I have had tests to find out just what kind of pollen I am
allergic to, and it turns out that I am allergic to several different kinds. I
have learned over the years that my symptoms will get worse at certain times of
the year, and I try to avoid being exposed to pollen during those times. My
doctor and I also have spent a lot of time finding out which antihistamines and
allergy medicines work for me without a lot of side effects. I feel like I
manage my allergies well, so I'm not going to have the shots from my doctor or use tablets that dissolve under my tongue. I have lots
of postnasal drainage from my allergies, and I get several sinus infections
every year during allergy season. I could take drugs to treat a runny nose, but
these other problems-and the side effects of the drugs-really affect my quality
of life. My doctor has narrowed it down to just a couple of things that I am
most allergic to, and I am going to try 1 or 2 years of allergy shots to see if
they will help reduce my post-nasal drip and control my sinus infection
problems. I have seasonal allergies that trigger my
asthma during allergy season. I know that trees and ragweed trigger my
symptoms, so when these are blooming, I try to avoid them as much as possible.
Since avoiding these pollens seems to help, I don't want to go through with the
skin testing to find out if immunotherapy is an option for me. I have
asthma, and it gets worse during allergy season. I love being outside during
the spring and summer, and I exercise outside a lot. My allergist told me that
allergy shots could help my asthma during allergy season and during the whole
year. I will do anything to be able to spend more time outside when it is such
beautiful weather. I am definitely going to try allergy shots to reduce my
asthma symptoms. I think the hassle of having shots every
week for years would be a lot worse than dealing with my runny nose and itchy
eyes for a few months every year. Maybe I will buy some stock in the tissue and
antihistamine companies! What matters most to you?
