Side Effects Of Immunotherapy Injections
Some patients develop a localised swelling at the site of the injection. This can be treated with non-sedating oral antihistamines or ice packs and if painful, Paracetamol. If the swelling is significant, your doctor may need to reduce the next dose.
More severe reactions are uncommon, however predicting who might have the serious reactions is difficult. Patients are normally advised to:
- Remain in their doctor’s surgery for at least 30 minutes after injection.
- Avoid exercising for at least 3 hours afterwards.
- Avoid some heart and blood pressure medications . Must be discussed with the prescribing doctor.
- Taking a non-sedating oral antihistamine before the injection may reduce the risk of side effects and may be recommended by your doctor.
It is important to inform your doctor about any reactions you may have experienced after your last injection and any new medications you are taking , or if you become pregnant.
Patients who are pregnant , are not routinely commenced on allergen immunotherapy until after they have given birth. If the patient is on maintenance doses of allergen immunotherapy and then becomes pregnant, the injections can be continued , but the supervising specialist should be contacted to discuss relevant safety issues.

Conditions For Which Immunotherapy Is Unhelpful
It is unusual for patients to receive immunotherapy for more than two allergies. Where a patient has severe symptoms caused by a number of different allergens they may be given immunotherapy for one or two of these so that symptoms are reduced to the level where they can be managed by the usual drug treatments.
Rashes such as eczema and nettle rash cannot be treated with immunotherapy. Research is ongoing into whether certain forms of immunotherapy might be helpful in severe atopic eczema.

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.

Allergen Immunotherapy Switches Off Allergy
Although medications available for allergy are usually very effective, they do not cure people of allergies. Allergen immunotherapy is the closest thing we have for a “cure” for allergy, reducing the severity of symptoms and the need for medication for many allergy sufferers.
Allergen immunotherapy involves the regular administration of gradually increasing doses of allergen extracts over a period of years. Immunotherapy can be given to patients as an injection or as tablets, sprays or drops under the tongue .
Allergen immunotherapy changes the way the immune system reacts to allergens, by switching off allergy. The end result is that you become immune to the allergens, so that you can tolerate them with fewer or no symptoms.
Allergen immunotherapy is not, however, a quick fix form of treatment. Those agreeing to allergen immunotherapy need to be committed to 3-5 years of treatment for it to work, and to cooperate with your doctor to minimise the frequency of side effects.
Pharmacologic Treatment And Allergen Avoidance
Patients were educated about specific allergen avoidance measures that include using allergen-proof mattress and pillow covers, washing bedding regularly with hot water, removing dust using damp duster, frequent vacuum cleaning with HEPA filter, removing soft toys from the bedrooms, keeping low humidity and avoiding upholstered furniture. Appropriate pharmacological treatment was initiated that included Intra nasal cortico steriod , oral antihistamines, oral leukotriene receptor blockers , inhaled corticosteroids and long-acting beta-agonists . Patients were then reassessed monthly and the PT dose was accordingly modified. Oral drugs whenever indicated were required for only a few weeks. ICS-LABA and INS treatment was discontinued when the patient was asymptomatic for 3 months with minimal dose. Treatment groups were classified and compared according to the percentage of successful discontinuation of ICS at the end of 3 years of AIT. Successful discontinuation was defined as being asymptomatic after cessation of ICS treatment for at least 6 months.

What Are The Risks Of Allergen Immunotherapy
Some people experience a swelling at the site of the injection. The greatest risk, is a severe allergic reaction although this is very rare. Just in case, you will normally have to stay in the doctor’s surgery for 30 minutes after treatment and avoid exercising for a few hours. Taking an antihistamine first may reduce the chance of side effects.
If you have sublingual immunotherapy, you may have minor swelling or itching inside your mouth, or an upset stomach. Serious side effects are very rare.
How Long Do They Take To Work
It varies from patient to patient. Some find relief from symptoms in just a few months during the build-up phase. Others require a full year of consistent treatment to see significant improvement.
You should talk to your doctor if youre concerned that your symptoms arent going away. Adjusting your shot schedule or slightly reformulating your medicine may help.

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.

How Often Do You Get Allergy Shots
At first, youâll go to your doctor once or twice a week for several months. Youâll get the shot in your upper arm. It’ll contain a tiny amount of the thing youâre allergic to — pollen, pet dander, mold, dust mites, or bee venom, for example.
The dose will go up gradually until you get to whatâs called a maintenance dose. After that, youâll usually get a shot every 2-4 weeks for 4-5 months. Then your doctor will gradually increase the time between shots until youâre getting them about once a month for 3-5 years. During that time, your allergy symptoms will get better and may even go away.
If your symptoms donât improve after a year of shots, talk with your doctor about other treatment options.

How Should I Prepare For Allergy Shots
You may want to avoid exercise or doing anything strenuous for 2 hours before and after your appointment. Thatâs because exercise boosts blood flow to the tissues and may cause the allergens to spread throughout your body faster. Itâs not likely to cause a serious problem, but itâs best to be safe.
Tell your doctor about any other medicines or herbs and supplements you take. Some medications interfere with the treatment or raise the risk of side effects. You may need to stop allergy shots if you take these medications.
If youâre pregnant or planning to get pregnant, ask your doctor whether you should continue to get allergy shots.
Is Sublingual Immunotherapy Effective And Safe
Most clinical trials and surveys published over the past 20 years show that SLIT is relatively safe and effective for the treatment of rhinitis and asthma caused by allergies to dust mites, grass, ragweed, cat dander, and tree pollens. Evidence is emerging that SLIT may be effective for treating the red, itchy eyes caused by pollen during hay fever season. 3-7 In addition, it might prove an effective therapy for children with mild atopic dermatitis and is currently being studied for its potential in treating food allergies. Currently, the best option for people with food allergies is to strictly avoid that food.
Side effects that may appear in both children and adults are usually local and mild, most often occur early in treatment, and include itching in the mouth or stomach problems. These can usually be managed by dose adjustments. Very rarely, severe allergic reactions have been reported using SLIT. Therefore this treatment is best prescribed by a medical practitioner experienced in the field of allergy.

How Do Allergy Shots Work
Allergy shots work by gradually exposing your immune system to the specific substances youre allergic to, therefore, training it not to react or cause symptoms. If you start immunotherapy, youll go into your allergist office for treatment over several years.
During the appointments, you receive an injection filled with your specific allergen. Your allergist uses a very limited dose of the allergen at first, then increases it slowly over time. The goal of the treatment is to create an immunity or desensitization to the allergen.
When immunotherapy first begins, youll see your allergist once or twice weekly. This is called the build-up phase because youre building up the amount of the allergen in your system. You will eventually reach a maintenance dose, which is the maximum dose and concentration for your allergens that is considered optimal for therapeutic response.
Once youre on the maintenance dose, your allergist visits for injections will decrease in frequency in a sequential pattern over time until eventually you will reduce to just monthly appointments. This maintenance phase usually lasts for three to five years for the best therapeutic benefit and long-term relief of your symptoms.

Current and Future Trends in Allergen Immunotherapy
Recent advances in understanding the mechanism and the long-term effects of immunotherapy are encouraging for future therapies. There are also new approaches being used to improve safety and overcoming the risk of severe adverse allergic reactions during immunotherapy. Newer allergen preparations available include allergoids, recombinant allergens , and modified-recombinant allergens . Studies on virus-like particles and CpG-motifs, adjuvants like MPL, and aluminum hydroxide have been shown to increase immunological response and can improve safety and efficacy. Other newer approaches to allergen immunotherapy include the application of extract patches on the skin and/or inguinal lymph node injection. Furthermore, recombinant technology or chemicals may alter allergen molecules that make them less reactive this may be due to suppression of Th2 responses or stimulation of toll-like receptors . The new advances in allergy immunotherapy not only provide disease-modifying treatments but are also cost-effective and improve the quality of life. Yet, with the historical efficacy and safety of immunotherapy, it remains underutilized.

What Are Allergy Shots
Allergy shots are also called subcutaneous immunotherapy . Subcutaneous means the shot is given under your skin, unlike vaccine shots, which go in your muscle. Immunotherapy means that the allergy shots are actually training your immune system not to react to something. In this case, thats an allergen.
Allergy shots contain small amounts of an allergen. When a person gets an allergy shot, they are injected with the allergen they are allergic to. The goal is to teach the immune system to stop overreacting to that allergen. A trained healthcare provider will give these shots starting with a small dose of the allergen. Over a period of months, the dose will increase. Eventually, the immune system can tolerate a high allergen dose without having a serious reaction.
Allergy shots begin with a build-up phase. During this phase, you will get an allergy shot once every 1 to 3 weeks for several months. Then you will move to the maintenance phase where you get a shot every 4 to 6 weeks. This entire process can take 3 to 5 years.
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.
- People with allergies covered about 19 percent of the total costs, while insurers covered about 81 percent.
- On average, treatment lasted 463.1 days .
Before beginning any treatment, talk with your doctor about payment options and costs.
Keep in mind that allergy shots are a long-term commitment. They require many injections, so youll want to plan accordingly if youre paying out of pocket.
Also consider that, over time, allergy shots could save you money on sick visits and over-the-counter allergy medications.

Allergy Shots Are Effective
Allergy shots are usually a very effective way of treating chronic allergies. It may take some time, but most people find that regular shots can help them when other common treatments havent worked. Studies show that 85% of people who suffer from hay fever see a reduction in their symptoms when they receive shots.
Many people avoid allergy shots because theyre afraid of injections. But the benefit is that the pain of an injection lasts just a moment while the relief of no more symptoms can last a lifetime.
Immunotherapy Injections Versus Sublingual Immunotherapy
Immunotherapy has been given by injection for more than 100 years and many studies prove that it is effective. A number of studies published in the last five years have shown that very high dose sublingual immunotherapy , where allergen extracts are retained under the tongue for a few minutes, then swallowed, can also be effective. SLIT has a longer history of use in Europe than in Australia and New Zealand, where it is used more commonly than injected immunotherapy.
The allergen extracts currently available in Australia and New Zealand for oral and injected therapy are very potent, and are NOT the extremely weak and ineffective extracts used by some medical practitioners ten or more years ago.

How Do I Avoid Allergens
The best way to prevent allergy symptoms and limit your need for allergy medicine is to avoid your allergens as much as possible. This includes removing the source of allergens from your home and other places you spend time. You can also reduce your symptoms to airborne allergens by washing out your nose daily. You can do this by using a nasal saline rinse using a squeeze bottle or a Neti pot.
What Is Sublingual Immunotherapy
Immunotherapy treats the cause of allergies by giving small doses of what a person is allergic to, which increases immunity or tolerance to the allergen and reduces the allergic symptoms. Unlike injection immunotherapy, which is given as shots, sublingual immunotherapy is given as drops under the tongue.

Managing Your Allergies With Immunotherapy
Immunotherapy is an innovative approach to allergy management that focuses on increasing your tolerance to the substances youre allergic to until you no longer experience symptoms. This approach is a long-term treatment solution because it takes time to build up your bodys resistance against an allergen. But once youre desensitized, you wont have to worry about having a severe reaction or possibly any reaction at all to that allergen.
We usually recommend immunotherapy through allergy shots to lessen or resolve symptoms of seasonal allergies like pollen and ragweed and indoor allergies like dust mites and animal dander. We also offer venom immunotherapy for stinging insect allergies.
Will My Allergies Be Cured
Allergies are not like a bacterial infection that is cured when bacteria are killed with antibiotics. Allergy symptoms are your immune systems response to otherwise harmless substances called allergens. Shots can help desensitize your immune system to these agents by inducing tolerance.
Some find their symptoms completely disappear and never return. Others may enjoy relief for several years before symptoms resurface. Your bodys response depends on your own immune system.

All That Said Are Allergy Shots Worth A Shot
Allergy shots can relieve allergy symptoms. Many people who get allergy shots are able to stop using their allergy medication completely because they no longer have symptoms. Other people report significant improvement in their symptoms and are able to use less medication. This relief can last for several years, but relapses may happen. In these cases, it is possible to restart allergy shots.
Who Can Benefit From Slit
Children and adults can both receive SLIT. If you are an older adult and considering SLIT but have medical conditions such as severe asthma, high blood pressure or other serious illnesses, please discuss the therapy with your allergist or physician first.
Regardless of your health condition, you and your allergist or physician should discuss Sublingual Immunotherapy, including:
- The type of symptoms you are having, the severity and whether they are seasonal or year-round
- Whether medications and/or environmental controls are helping your allergy symptoms
- Any concerns about long-term medication use
- The commitment to treatment
- The cost involved and individual insurance coverage
SLIT is not used to treat food allergies but there is research underway to evaluate this form of treatment.
