When Should A Child Be Tested For Allergies

How Do Allergy Shots Work

Before going into the best age to begin allergy shots, it’s important to talk about when to have your child tested for allergies, as this step comes first. Parents often believe that allergy testing for children has to wait until a child is a certain age, for example, school age. This is not true, and allergy testing can be done for children even one month of age. The best time to test is when you believe knowing the source of your child’s symptoms outweighs the discomfort of the procedure, and this age will be different for every child. Your best bet is to talk to your pediatrician or allergist in order to have her help you weigh these factors.

Why Do I Have Allergies

Allergies are a sign of an overactive immune system. If you have allergies, your body overreacts to substances that are safe for most people, such as:

  • Pollen
  • Tingling
  • Nausea and vomiting

A severe form of reaction anaphylaxis may make it difficult to breathe or cause you to lose consciousness. Anaphylaxis is potentially deadly. If youre at risk for anaphylaxis, we prescribe an epinephrine pen that you carry with you wherever you go.

Allergen Immunotherapy Is Beneficial In Certain Allergic Conditions

Allergen immunotherapy is usually recommended for the treatment of potentially life threatening allergic reactions to stinging insects. Published data on allergen immunotherapy injections shows that venom immunotherapy can reduce the risk of a severe reaction in adults from around 60 % per sting, down to less than 10%. In Australia and New Zealand, venom immunotherapy is currently available for bee and wasp allergy. Jack Jumper Ant immunotherapy is available in Tasmania and a limited number of other regions.

Allergen immunotherapy is often recommended for treatment of allergic rhinitis due to pollen or dust mite allergy when:

  • Symptoms are severe.
  • The cause is difficult to avoid, such as grass pollen.
  • Medications don’t help or cause adverse side effects.
  • People prefer to avoid medications.

Allergen immunotherapy is only occasionally recommended for the treatment of atopic eczema as evidence of its effectiveness is limited, although recently published studies have shown good results in some patients. Evidence that food allergy can be controlled in this way is very limited, although research is ongoing.

Improvement with allergen immunotherapy does not occur immediately. It usually requires at least 4-5 months before symptoms improve, sometimes longer. If you are having treatment because of spring/summer allergic rhinitis, you will usually see improvement quite clearly in the first season.

Why Should I Get Allergy Shots

Most people get allergy shots once they have tried other treatments that did not work. These can include avoiding allergens and taking medicine, such as an antihistamine.

Before starting allergy shots, your doctor will do an allergy test to determine the allergen. For a skin test, the doctor puts tiny amounts of allergens onto your skin using needles to see which ones you react to. For a blood test, the doctor may do a radioallergosorbent test or ImmunoCap test.

What It’s Used For

Allergy Myth Busters

Common allergic symptoms are sneezing, runny nose, itchy eyes or asthma attacks. Allergy symptoms are caused by your body’s reaction to a substance that is inhaled, touched or eaten. Allergens cause no symptoms in a non-allergic person, but in an allergic person who is sensitized to that antigen, an immune reaction against the allergen causes symptoms.

In allergic reactions, the body responds to the allergen in the same way it would respond to fight off infection by a parasite. The immune system recognizes the substance as foreign and activates an army of antibodies to eliminate the invader. The antibodies bind with the allergen and then trigger immune system cells to release chemicals, such as histamine. This release of histamine is what causes most allergy symptoms.

Allergy shots, also known as allergen immunotherapy, cause the body to stop generating symptoms after exposure to certain allergens. Tiny amounts of the offending substance are injected under the skin with each shot. The shots stimulate the immune system just a little each time. Gradually, over weeks and months, the amount of allergen is increased.

This very constant, low-level exposure stimulates a different type of immune reaction against the allergen. This new pattern of immune reaction substitutes for and is less bothersome than a traditional allergic response.

Avoidance of foods to which you are allergic currently the best strategy for preventing food allergy reactions.

How Well Do The Treatments Work

If you stick with allergy shots long enough, thereâs a good chance youâll see improvement or even an end to your allergy symptoms. About 85% of people with hay fever who get this type of treatment say their allergy symptoms get better.

âThatâs one of the things I find pretty neat as an allergist,â Wada says. âTypically, a lot of the treatments we have are geared toward treating the symptoms. This is one of the few things we have toward the root of the problem.â

Sublingual treatments havenât been studied as much as allergy shots. They havenât been shown to work as well as allergy shots. But if youâre up for the commitment of taking the medicine day in, day out, as prescribed, it might be an option to explore for the specific allergies it targets.

Youll Have To Stick To A Schedule

For treatment to be most effective, youll need to create an allergy shot plan that involves multiple doses over a period of time.

Exactly how many doses youll need and for how long will depend on your individual situation. Dr. Reichmuth, one of the expert immunologists at Florida Medical Clinic, says your doctor will work with you to create a schedule best suited for your symptoms.

Schedules are split into two phases: the build-up phase and the maintenance phase.

During the buildup phase, allergy injections are given more frequently, typically 1-2 times a week for 4-8 months. During maintenance phase, the injections become less frequent according to the plan you create with your immunologist.

For Which Types Of Allergies Does Immunotherapy Work

Allergy shots are effective for many kinds of allergic rhino-conjunctivitis, which mostly impact the nose and eyes. They include:

  • Pollen
  • Seasonal allergies
  • Mold/mildew oversensitivity

They can also be used to treat other types of allergies like those that cause hives, anaphylaxis, and allergic asthma such as:

  • Insect sting allergies
  • Food allergies
  • Medication allergies

They may also help with some forms of dermatitis, in which the skin responds to being touched by an allergen.

How Much Are Allergy Shots For Dogs

How do allergy shots work?

You might have to pay a bit extra up front for your dogs immunotherapy but for many pet parents, its totally worth it in the end.

You can expect initial allergy testing costs to be around $1,000 or more , and each allergy shot can cost anywhere from $5 to $25.

Keep in mind that once you reach a maintenance schedule for the allergy shots, you might actually save money by not needing to buy prescription allergy medicine, OTC antihistamines or medicated dog shampoo anymore.

Plus, if your dog has serious allergies that cause a lot of discomfort, the benefit from allergy shots can be life-changing .

Immunotherapy can be a great solution to a dogs allergies problems. But there is no one best method of allergy treatment for every dog, so have a conversation with your vet, who can help you develop the perfect treatment plan for your pup ASAP!

How Effective Are Allergy Shots For Dogs

Allergy shots are considered to be pretty effective and even in cases when they dont completely fix a dogs allergies, they can still help improve your dogs allergy symptoms.

It’s about 70 to 80 percent effective, but that’s along a spectrum, Dr. Harbour said. Some patients will completely improve, others will have less severe flares and we can potentially reduce their medications over time, and others it may be hard to notice actual improvement, but it may be simply preventing progression/worsening of disease over time.

So even if the allergy shots dont help your dog with his immediate allergies, its possible that immunotherapy can actually prevent his symptoms from getting worse in the long run.

Can Everyone Get Allergy Shots

No. If you have severe asthma or heart problems, allergy shots may not be good for you. You shouldn’t get allergy shots if you take a beta blocker for heart problems. Children younger than five years of age also shouldn’t get allergy shots.

Allergy shots shouldn’t be started when a woman is pregnant. But if a woman has been taking allergy shots for some time and becomes pregnant, she can continue taking her allergy shots. Talk to your doctor about taking allergy shots while you are pregnant.

What Should I Expect Afterward

Usually, youâll stay at the doctorâs office for about 30 minutes after you get an allergy shot. That’s to make sure you don’t get side effects like itchy eyes, shortness of breath, a runny nose, or a tight throat. If you get these symptoms after you leave, go back to your doctor’s office or to the nearest emergency room.

Redness, swelling, or irritation right around the site of the injection is normal. These symptoms should go away in 4 to 8 hours.

They Can Take A Few Years To Really Work

Do Allergy Shots Really Work?

Allergy shots aren’t a quick fix: While some people may start to feel better during the build-up phase of their treatment, most people won’t experience noticeable improvement until they’ve been in the maintenance phase for six to 18 months, says Dr. Dziadzio.

In fact, a 2017 British study found that it took three full years for allergy shots for hay fever to be more effective than placebo shots. The maintenance phase for most allergy shots is usually continued for three to five years. Some patients experience long-lasting relief after that, and some may need continued treatment.

What Can Affect How Well They Work

The effectiveness of the treatment does vary. Often this is to do with the length of the program a person is undertaking or the dose of the allergen.

Some people will have lasting relief while others may have a relapse after treatment has stopped. If a person experiences no improvement after 12 months of allergy shots, it could be due to several factors:

  • wrong dose of the allergen in the allergy shot
  • missed allergens in the individual when they are first evaluated
  • high levels of the allergen in the environment the person is in
  • exposure to non-allergic triggers, such as tobacco smoke

If allergy shots are not working, for whatever reason, then an allergist or immunologist will be able to discuss alternative treatment options.

Normally, the only side effect that people experience after having an allergy shot is redness or swelling at the site of the injection. This can happen immediately after the injection or a few hours afterward.

In some cases, people can experience increased allergy symptoms, such as:

  • sneezing
  • nausea
  • dizziness

Anaphylactic shock needs to be treated immediately with an injection of epinephrine, which is also called adrenaline.

A second anaphylactic reaction called a biphasic reaction can occur up to 12 hours after the initial shock.

Allergy shots have traditionally been the most common form of immunotherapy and are known as subcutaneous immunotherapy or SCIT.

This treatment is when an allergen is injected under the skin.

My Experience With Allergy Shots

During the first visit I was really nervous. The nurse explained that I might have a reaction to the shots, so during every appointment I would have to wait 15-20 minutes after receiving the shot to see if I had a reaction. With my 2-year-old daughter next to me, holding my hand , I braced for the nurse to inject me with the needle filled with substances I knew I was allergic to. I felt a slight pinch and then a little bit of burning and then it was all over in seconds. I read some childrens books to my daughter while we waited to be sent home. Luckily, I didnt have any reaction.

This became our weekly routine and then tapered off as the doctor had explained when I first began. After two years of treatments, I was tested again for allergies. I was no longer allergic to dust mites and dogs. I was still allergic to mold but the allergist said often that allergen does not respond well to the allergy shots. He told me that I could continue to receive the shots for mold for another three years, but that I still might be allergic.

Allergy shots only work if we are able to reach the doses we need to reach and if someone consistently gets their maintenance dose to allow for the body to change the way it reacts to the things you are allergic to, says Gupta.

After the two years of shots, I noticed my tissue supply hardly needed replenishing. I also didnt need to carry around a pack of tissues in my pocket anymore. So I decided not to continue getting the shots.

Are Allergy Shots Right For You

While we recommend you visit your doctor or allergist to ascertain whether youre a good candidate for allergy shots, these questions will also help you decide:

  • What are your allergies? If youre allergic to one or more of the substances listed above, then allergy shots can help lessen your symptoms. However, if you have an allergy to latex, drugs, or certain foods, immunotherapy is not recommended.
  • How bad are your allergies? If symptoms persist for longer than three out of 12 months or are impacting your daily activities then allergy shots may provide more relief than other treatment methods.
  • What other treatments have you tried? If youre on a prescription antihistamine or another medication from an allergist but these dont help your symptoms, let your allergist know. They could recommend immunotherapy as your next treatment.
  • Are you okay with needles? If you have a severe fear of or significant discomfort associated with needles, then you might want to rethink allergy shots. While its true the injections become less frequent as the treatment goes on, it will take a while to get there. You may want to discuss sublingual immunotherapy or SLIT with your allergist. This treatment involves you taking tablets or drops under your tongue instead of receiving injections.

What Should You Do If Your Usual Allergy Meds Don’t Work

Allergy Shots Overview

Many treatments are available to ease your allergy symptoms, including nasal sprays , eye drops, and antihistamines. “Oral antihistamines help the itchy, sneezy and runny nose, while intranasal antihistamines help the itchy, sneezy, runny, and congested nose,” explains Rhonda J. Myers, MD, PhD, allergist with Providence St. Joseph Hospital in Orange County, California. Another option is intranasal corticosteroids, which help all these symptoms but must be used daily to be effective, Myers tells Health.

If your usual meds aren’t working, it’s time to see your doctor again. “An allergist has advanced training and experience to properly diagnose your condition with a good history, examination, skin testing, or a blood test,” Dr. Fonacier explains. “They can help you identify your allergy triggers, provide advice on how to avoid them, and even detect complications early.

There are several possible reasons for your meds not working, including the wrong diagnosis , high exposure to the allergen, or inability to avoid the exposure. You might also have started your treatment too late, Dr. Fonacier says. Whatever is at the root of it, your doctor can help you get to the bottom of itand hopefully find some relief from the sneezing.

And that leaves the final category, allergies to environmental stimuli, which afflict between 10 and 20 percent of dogs. In fact, an environmental allergywhich includes allergy to grasses, pollens, insects, and moreis diagnosed only after ruling out all other possible causes of the allergic signs.

In environmental allergies, the immune system overreacts to these allergens and causes a variety of signs, including itching, skin inflammation, skin infections, and ear infections, says Dr. Miller.

Unfortunately, we cannot treat environmental allergies by removing grass, trees, dust, mold spores, and so on from our pets environment. So, instead of changing the pets environment, we have to mediate the pets allergic reaction.

Immunotherapy, commonly known as allergy shots, is one of the oldest and still most effective treatment options for environmental allergies in dogs, says Dr. Miller. It is the only natural way to truly try to change the immune systems response to allergens, but it requires a long-term commitment on the part of the pet owner.

When Should You Start Taking Your Allergy Meds

As a general rule, allergy treatment should begin at least a couple of weeks before the start of allergy season, to help you stay ahead of the itching, sneezing, drippy nose, and wheezing. “The majority of hay fever medications work best if started before a pollen season begins,”Luz Fonacier, MD, Head of Allergy at NYU Langone HospitalLong Island and president of the American College of Allergy, Asthma and Immunology , tells Health.

If you use nasal antihistamines, steroids, oral antihistamines, or eye drops for seasonal allergies, Dr. Fonacier advises against waiting until your symptoms are unbearable to start treatment. And don’t stop taking them too early, either. “The misery can linger until the end of the season, so wait a few weeks before stopping treatment,” she says.
