Blocking Allergy Symptoms: How Pretreatment Works

How Do Allergy Shots Work

Tackle allergies before they start, and you could be breathing a lot easier.

For lots of people, allergy treatment is reactive. You get stuffed up, your eyes water, and then you go to the medicine cabinet for relief. But many doctors say that weâve got it the wrong way around. Instead, we should be taking the medicine before we have symptoms. Call it allergy pretreatment.

âWe always tell people to start taking medicine before the allergy season begins,â says Jonathan A. Bernstein MD, an allergist and professor of clinical medicine at the University of Cincinnati. âPeople often come to me in the middle of the allergy season, and theyâre already a mess. Once the symptoms start, they can be like a runaway train.â

By waiting, you could be risking more than mild discomfort. Once allergy symptoms start, you might need more heavy-duty medicine to get them under control. In some people, allergy symptoms quickly turn into allergic sinusitis and more serious problems. That requires even more intensive treatment.

So the key to getting through the allergy season is to have a good defense. By arming yourself with medicine before the trees unleash their pollen â or before you go visit your sister and their five cats â you can save yourself a lot of suffering. How does allergy pretreatment work? Here are the answers.

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.

Disadvantages Of Allergy Immunotherapy

As with all types of medical procedures and treatments, allergy desensitization has some drawbacks. Following are some of the more common disadvantages of allergy shots:

  • Immunotherapy does not work on every type of allergy. It is true that shots work well for common allergies such as pet dander, pollen, dust, and other pollutants found in the home. Shots are ineffective for treating food allergies and urticaria. Urticaria causes chronic hives related to an underlying disease such as hyperthyroidism or lupus. In addition, insect venom allergies such as bee stings or spider bites cannot be prevented by allergy shots.
  • Some patients have a reaction that shows up as redness, swelling, and tenderness at the injection site. However, injection site reactions usually last just one day.
  • Occasionally, certain patients balk at the time commitment needed for successful allergy prevention. Missing appointments can delay or derail relief from allergies.
  • Allergy shots can worsen allergy symptoms at first when the injection regimen starts.
  • Since allergy shots rarely cause anaphylaxis, patients must wait in their physicians office for 30 minutes until the danger of anaphylaxis passes.

Most Insurances Have You Covered

Allergy shots are typically covered by most health insurances, though this may vary depending on your specific plan. Even if your shots are covered by insurance, you still may have to pay a copay for each visit. For some, this cost may be cheaper than the total price of over-the-counter medications and other sick visits related to hay fever symptoms.

If you have questions about your insurance coverage, we encourage you to reach out to your insurer. Otherwise, you can discuss costs with your healthcare provider directly.

Allergy Shots: How Long Before They Start Working

Allergen immunotherapy, also known as allergy shots, is considered a long-term treatment that decreases symptoms for many people with allergic rhinitis, allergic asthma or stinging insect allergy. Allergy shots can also be effective for people with hay fever and other seasonal allergies, as well as for year-round indoor allergies like mold, dust mites, and animal dander.

Allergies are often treated symptomatically. This means managing and treating the symptoms rather than the cause. There are numerous medications that can inhibit the release of histamine and other allergy-inducing chemicals. They help alleviate symptoms like redness, itching, swelling, and difficulty of breathing.

However, none of these therapies address the cause of the allergy none of these therapies try to modify how the immune system reacts to allergens so that future attacks are prevented. Immunotherapy does exactly that. So, what is immunotherapy?

What is Immunotherapy?

Immunotherapy, also called allergy shots, is a series of vaccinations containing a specific allergen. The goal of immunotherapy is to condition the immune system to tolerate a specific stimulus or allergen so that symptoms and future occurrences are reduced.

When the immune system learns to handle the allergen, symptoms are less likely to show up. If symptoms do occur, they are not as serious and they do not stay for very long.

Who Should Not Take Claritin

While Claritin is generally well tolerated by most people, there are some individuals who should not take Claritin or who should speak to their doctor prior to using the medication. People who have had an allergic reaction to Claritin or desloratadine should not use Claritin. If you have experienced other allergic reactions to medication, tell your doctor or pharmacist so that they can ensure there are no inactive ingredients included in Claritin that could cause an allergic reaction.Be sure to share a complete medical history with your doctor prior to using Claritin. Although Claritin is available over the counter, people with a history of kidney or liver disease should not take Claritin prior to consulting with their doctors.Although Claritin is less likely to cause drowsiness and have a sedative effect than some other antihistamines, some people will still experience these side effects. You should not drive, use machinery, or do any activity that requires alertness until you determine how taking Claritin affects you. Older adults may be more likely to experience these side effects and may also be at increased risk of experiencing confusion, which could increase the risk of falling.

Who Is A Good Candidate For Rush Immunotherapy

I do caution my patients that the risk of having an allergic reaction to an allergy shot is a little higher during the rush protocol. However, because we keep you here for observation after each injection, were able to provide quick treatment. And even if you have a reaction on the first day, we still can shave months off the process even if we cant complete the full rush protocol.

I might not recommend rush immunotherapy for very young children. Thats mainly because shots can be scary for kids. Having to get many shots on the first day could be traumatizing for them and make it harder for them to deal with needles later. Thats something parents can talk over with their childs allergist.

Its important to see a board-certified allergist like me whenever youre considering options for allergy treatment. Although rush immunotherapy was first developed in the mid-1990s, its not widely known among doctors who dont focus strictly on allergy care.

For most patients, rush immunotherapy is a great alternative to traditional allergy shots. It can help you feel better faster and save time in the process. Request an appointment with one of our allergists to find out if rush is a good option for you.

How Do I Start Sublingual Immunotherapy

Request an appointment for allergy testing and an evaluation to see if you are likely to benefit from sublingual immunotherapy. If you are, the vials take one to two weeks to mix. Dr. Lin will see you once or twice per year to monitor your progress. During therapy, when your last vial is half empty, please call our office to order your new vial.

Reactions To Allergy Shots

Reactions to allergy shots are common. Most reactions are local . Rarely, reactions can affect your entire body. This is referred to as a systemic reaction, and it can be dangerous. For this reason you must stay in our office for 30 minutes following every shot appointment. Additionally, you should not exercise for 2 hours after your shots.

If you are having asthma symptoms when you are scheduled for an allergy shot it is important to tell your nurse. Allergy shots can worsen asthma symptoms.

Getting Your Allergy Shots

  • For the next 3 to 5 years, you receive the shots less often, about every 4 to 6 weeks.

Keep in mind that many visits are needed to get the full effects of this treatment. Your provider will assess your symptoms now and then to help decide when you can stop receiving the shots.

Pros And Cons Of An Accelerated Schedule

The most obvious advantage of an accelerated allergy shot schedule is that youll receive lasting relief from allergy symptoms faster and with fewer visits to the allergist.

Over time, an accelerated schedule could save you money and time. You wont be missing work and traveling to see an allergist as much as patients on a conventional schedule.

One disadvantage of an accelerated allergy shot schedule is that some patients suffer greater allergic reactions to the shots, although antihistamines and corticosteroids can prevent or minimize adverse reactions.

How Long After I Start Taking The Allergy Shots Before I Feel Better

It usually takes six months or more of allergy shots before you start feeling better and notice relief of your allergy symptoms. If you don’t feel better after this much time, you should probably talk with your doctor about another kind of treatment for your allergies.

What Are The Downsides

The most obvious drawback for allergy shots is the time commitment. You must stick to a weekly schedule of allergist visits for months, and it could be years of monthly follow-ups before you see significant improvement.

That said, symptoms generally start to improve within the first year of treatment and often continue to get better during the second year. By the third to fifth year, most people are free of allergy symptoms and may be able to stop getting shots.

Aside from time, thereâs the potential for a reaction to the treatment, since it has small amounts of the things youâre allergic to. For instance, you may have redness or swelling around the injection site if you get a shot, or you may have other symptoms.

âSometimes, patients report an increase in nose or eye symptoms, such as stuffy nose, runny nose, or itchy eyes,â says allergy immunologist Kathleen Dass, MD, of the Michigan Allergy, Asthma & Immunology Center. While itâs rare, itâs also possible to have anaphylaxis, which is a severe allergic reaction involving hives, swelling, trouble breathing, dizziness, and/or loss of consciousness. Thatâs why you need to get the treatment in your allergistâs office and wait there for a while after each shot, Dass says.

Also, allergy shots can be expensive. While theyâre generally covered by insurance, if you have a high-deductible health plan, you may have to pay out of pocket until you hit your deductible each year.

What Medication Is Used For Allergy Shots

Experiences with allergy shots : Allergies

Allergy desensitization shots are made of allergen proteins mixed with preservatives and solvents. This is called an extract. Your doctor will give you the extract that matches your allergy. If youre allergic to cat dander, you will get the cat dander extract, for example.

Over time, your doctor will slowly increase the amount of allergen in your shots. The gradual buildup changes your immune system and desensitizes it to the allergen. Your body gets used to the allergen, and you become less likely to react to it.

There are also other forms of desensitization treatment called sublingual immunotherapy. These are drops or tablets of extract that you put under your tongue for 1 to 2 minutes and then swallow.

Not Fleas Or Food Try Environmental

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.
