Why Should You Get Allergy Shots At An Allergy Clinic

Do-It-Yourself Allergy Shots

Our board-certified allergist received years of extensive training in formulating allergen immunotherapy shots, which is necessary to provide safe, but effective treatment of allergies. Knowledge of which allergens can be safely mixed together, which allergens cross react, and the appropriate doses of each allergen extracts to meet efficacy guidelines is paramount in ensuring that the 4-5 years you spend completing a course of allergen immunotherapy is worthwhile. Many different types of providers are now offering allergy shots and it is important to make sure that the provider you trust with this process has the knowledge and training necessary to allow you to get the maximum benefit from your allergy shots, while doing so in the safest manner possible.

What Kind Of Allergy Shots Do I Need

The kind of shot you get depends on what youre allergic to. Before starting treatment, youll be tested to identify exactly what substances trigger your symptoms and determine what goes into your treatment.

For example, if you experience a lot of symptoms in the spring, you may have a pollen allergy. Youll be tested to determine exactly what type of pollen your immune system is reacting to. Your immunologist will then formulate allergy shots that are made just for you.

How Many Shots Will I Have To Get

You will start getting shots one or two times each week. After about six months of weekly shots, your doctor will decide when you can start maintenance treatment. These shots are usually given just once each month, year round. You’ll probably need to get monthly shots for three to five years. Then you may be able to stop getting shots.

What Types Of Allergies Do Allergy Shots Treat

There are over 1,200 allergen extracts licensed by the U.S. Food & Drug Administration. They are designed to work against environmental allergens: pollen, pet dander, mold, cockroaches, dust mites and also bee stings. Allergy shots are not given for and are not effective against food allergies. An allergist might use food allergen extracts to test for specific food allergies, but not for allergy shots.

Allergy shots (immunotherapy): Efficacy, side effects, and ...

When medications fail to adequately control allergy symptoms and avoidance of the trigger is not easy or possible, an allergist may recommend immunotherapy or allergy shots. This treatment consists of a series of injections containing small amounts of the substances to which a person is allergic.

After a course of allergy shots, patients have fewer allergy symptoms. Allergy shots can be given for allergic rhino-conjunctivitis , allergic asthma, and insect sting allergies.

Can Allergy Shots Help Kids

Yes! Allergy shots can be started at any age. The age in which shots may be recommended for young children is done on a case-by-case basis.

Research has also shown that allergy shots can prevent children who have allergic rhinitis from getting asthma. Treating the underlying cause of allergies in children can help prevent other sinus problems, improve quality of life, and help prevent your child from missing school due to allergy and asthma symptoms.

Allergy Shots For Dogs Side Effects

Luckily, there are very few side effects of immunotherapy in dogs.

One side effect is an increase in itchiness in the first couple of days after an injection.

This can occur up to 48 hours after the injection and can last for hours to days, Dr. Harbour said.

A more severe side effect of allergy shots for dogs is mild to moderate anaphylaxis, which can include the following symptoms:

  • Vomiting
  • Facial swelling
  • Hives

Signs of anaphylaxis are extremely rare in dogs and cats, but because this is possible, we start with low doses and increase the volume of injections to a maintenance dose that the patient can tolerate, Dr. Harbour said.

A Side Story: My Experience With Allergy Shots

Ive had serious allergies since I was very young. When they tested me for the various things I was allergic to, they drew a grid with one square per allergen. Every single square became an inflamed, itchy bump. Well, theres one square that didnt react, I pointed out to the nurse hopefully.

Oh honey, she said. Thats the control.

I started taking shots in my early 20s, but for various reasons I stopped for a few years. I started up again in my mid through late 20s. Even with health insurance, at the time money was tight and the copay took a bite out of our finances.

I never had any kind of systemic reaction from my shots. To be honest, after months and months of never having a reaction, I stopped waiting around the doctors office after the shots were administered. Id often get an itchy bump for a day or so, but thats it. Its also worth noting that, while you need an allergist to test and set up the serum, you can have your regular general practitioner do the weekly or monthly shots. This was great for me since my GP was much closer than my allergist.

How Do Allergy Shots Work

There are two phases to allergy shot therapy: a build-up phase and a maintenance phase.

  • Build-up phase: In this phase you will start with a low dose injection and build to a higher dose of allergens over time. For typical immunotherapy this phase lasts from 6 to 10 months, depending on how often you get your shots and how well you tolerate them. The build-up phase for venom therapy generally lasts for 10 weeks.
  • Maintenance phase: When you reach your effective therapeutic dose you will begin the maintenance phase. During this phase you receive your allergy shots less often, usually every 3 to 4 weeks. The maintenance phase typically lasts 3-5 years .

What Are Allergic Rhinitis And Allergic Asthma

Allergic rhinitis occurs when your immune system overreacts to particles in the air that you breatheĆ¢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 mould make your symptoms worse, it is known as allergic asthma.

They Contain Allergens So Reactions Can Happen

Allergy shots work by exposing patients to tiny amounts of whatever it is they’re allergic to. The amount of allergen in each injection increases gradually over time so the body can build up a tolerance.

“It changes the person’s immune system from having a bad reaction to pretty much ignoring the allergen,” says Dr. Dziadzio. “For some people, it decreases their allergies enough so they can come off medicine entirely, and for some it helps their medicines be more effective.”

But because allergens are involved, reactions to the shots themselves are possible. These can range from swelling and itching at the injection site to sneezing and a runny nose, to, in rare cases, anaphylactic shock. That’s why it’s recommended that patients stay at their doctor’s office for 30 minutes after each shot so they can be monitored and treated for reactions if they do occur.

Acentury Of Safe Treatment

Itsimportant to consult a board-certified allergist about shots. Very rarely, allergyshots can lead to anaphylactic shock. An allergists staff is trained to treatpotential systemic reactions such as hives, wheezing or hypotension.

The slight risk of reaction from shots should not be a deterrent, Dr. Purcell says. The allergen extracts used in shots are highly standardized today theyre produced consistently from batch to batch for reliable quality and dosing.

Shots have been given for more than 100 years. This is a therapy that has withstood the test of time, he says.

Ifyour allergies are making you miserable and you are willing to invest the time,consider asking an allergist if shots may be right for you.

Do I Need Allergy Shots

Allergy shots (immunotherapy): Efficacy, side effects, and ...

After allergy testing and diagnosis, our allergists treat patients with a three-tier approach. Avoidance is the first step to treatment. Using medications like antihistamines and nasal sprays is the second step. The third step is immunotherapy. If avoidance methods or the usual doses of medications control your symptoms, then immunotherapy might not be needed. Allergy shots have been proven effective against inhalant allergies and stinging insect allergies, however, they are not used for food allergies. If any of the following applies to you, then you may be a candidate for allergy shots:

  • If the medications to control your symptoms , do not work.
  • If the medication used to control your symptoms produces too many side effects.
  • If complications develop.
  • If you have asthma triggered by allergies.
  • If you are at risk of developing anaphylaxis when exposed to an allergen.
  • If medications control your symptoms, but your symptoms flare back up every time you try to reduce your medications.
  • If you cant effectively avoid things that trigger your allergies.
  • If you would rather take a series of allergy shots than daily medications.
  • If you would rather treat the actual problem rather than use medications to control symptoms.
  • If the cost of the medications is a burden, allergy shots are very cost-effective compared to the use of daily prescription medications over several years.

They Can Make Asthma And Eczema Better

When people think of allergy symptoms, they generally think of itchy eyes and a stuffy or runny nose, or, in worse-case scenarios, anaphylactic shock. And while allergy shots can help prevent all of those, they can also help with related conditions, as well.

If you have asthma, getting your allergies under control may also help reduce flare-ups, improve your breathing, and reduce your need for medications. Eczema, an inflammatory skin condition, is often associated with environmental allergies.

Allergy Shots: Could They Help Your Allergies

Another name for allergy shots is allergen immunotherapy. It is a type of treatment that relieves symptoms for people who have chronic allergies. Allergy shots contain small amounts of the thing you are allergic to, called an allergen. The first shot you get has a low amount of the allergen. The dose increases with each shot. Over time, this process helps your body fight the allergen. Your immune system creates antibodies to block its effect. The result is your allergy symptoms become less severe.

How Long Does It Take For The Allergy Shots To Start Working

It can take anywhere from three months to over a year for allergy shots to start working.

This is not a quick fix, Dr. Harbour said. Typically we tell clients that this is something we commit to for the long-haul.

In the meantime, your vet might recommend a prescription medication, like Apoquel or Atopica, to manage your dogs symptoms.

Or they might recommend a dog-safe over-the-counter antihistamine which is usually best paired with an omega-3 supplement.

Allergy Shots For Children

Yes, they are, but this is something that needs to be discussed with your allergist.Children, like adults, sometimes develop a minor reaction near the site of the injectionimmediately after the allergy shot is given. Simply applying ice to the area and administering anantihistamine can reduce the swelling.

They’re Not Recommended For Everyone

Most adultsand children ages 5 and upcan get allergy shots. But if you or your child has severe, uncontrolled asthma, your doctor may recommend against them. “In our practice, if a patient’s asthma is flaring or even if they’re sick, we generally wait to give the shot until they’re feeling better,” says Dr. Dziadzio.

Women who become pregnant while in the maintenance phase of allergy shots can continue their treatment. But women shouldn’t start allergy shots for the first time, or increase their dosage, while pregnant.

Certain medicines, like beta blockers, can reduce the effectiveness of epinephrinethe lifesaving drug used to treat anaphylactic shock. Because anaphylaxis is a rare but serious risk for people getting allergy shots, they may not be recommended for people who take these drugs.

Cytopoint Allergy Shot Vs Immunotherapy For Dogs

Immunotherapy should not be confused with cytopoint allergy shots, which are intended for short-term relief rather than as a permanent solution.

This is an anti-itch injection given at the veterinary practice that lasts four to eight weeks, Dr. Harbour said. This is a monoclonal antibody that targets the itch mediator and prevents the signal of itch from going to the brain.

So instead of training the immune system to reduce reactions for good like with immunotherapy cytopoint basically just tricks your dogs brain by making her think shes not itchy.

How Much Do Allergy Shots Cost

Health insurance typically covers allergy shots. You may have to pay a copay for each visit. Copays are usually nominal fees.

If you dont have health insurance, have a high deductible, or if allergy shots arent covered under your plan, you may end up spending thousands of dollars a year.

One large 2019 study looked at the costs of allergy shots for people with commercial insurance or Medicare Advantage with Part D. Researchers examined data gathered between 2013 and 2015.

  • The cost of allergy shots for 131,493 people totaled $253,301,575. This averages out to around $1,926 per person.
