Are There Side Effects With Allergy Shots
The most common side effect of allergy shots is a localized reaction. Localized reactions are very common. Between 30% to 80% of people who get allergy shots report a localized reaction. Localized reactions can include redness, swelling, and itching where you received your shot. These reactions can be very small, like the size of a mosquito bite, or quite large. The reaction can start shortly after you receive your shot and may increase in size over several hours. Most reactions last over 24 hours.
Localized reactions are bothersome but not dangerous. Most people treat localized reactions with ice and Benadryl.
A more serious side effect of allergy shots is anaphylactic reaction. Anaphylaxis is a severe allergy reaction that can be life threatening. This reaction usually happens within 30 minutes of receiving an allergy shot. Every person who gets allergy shots must stay at the office for at least half an hour afterward. A trained healthcare provider will watch you for signs of anaphylaxis.
Your healthcare provider will give you an EpiPen and instructions on symptoms of anaphylaxis so you can be prepared in case of emergencies. To be safe, always follow your healthcare providers instructions. Tell your provider about previous reactions to allergy shots, new medications you are taking, or changes in your health.
If you think you are having an anaphylactic reaction, seek help immediately and call 911.
A Shot Isn’t Your Only Option
For people who hate shots or can’t keep up with their intensive schedule, sub-lingual therapy may be another option. This type of immunotherapy is delivered in daily tablets that dissolve under the tongue, and only the first few doses need to be taken with a doctor present.
Sub-lingual therapies are currently on the market for grass pollen and for ragweed pollen . Some allergy practices will also administer liquid drops under-the-tongue to treat other types of allergies, although these treatments are not FDA-approved.

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.

Who Can Benefit From Allergy Shots
You may benefit from allergy shots if you have:
- Asthma that allergies make worse
- Allergic rhinitis, allergic conjunctivitis
- Eczema, a skin condition that a dust mite allergy can make worse
Allergy shots are effective for common allergens such as:
- Weed, ragweed, tree pollen
- Insect stings
Adults as well as children 5 years and older can receive allergy shots.
Your provider is not likely to recommend allergy shots for you if you:
- Have severe asthma.
- Have a heart condition.
- Take certain medicines, such as ACE inhibitors or beta-blockers.
- Are pregnant. Pregnant women should not begin allergy shots. But, they may be able to continue allergy shot treatment that was started before they became pregnant.
Food allergies are not treated with allergy shots.
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.

So How Can You Tell The Difference Between Covid
You cant, unless you get tested.
At the beginning, a lot of the early symptoms can overlap very frequently, Barron said. So runny nose, sore throat, headache, that could be a cold, or it could be COVID-19, or could even be early signs of the flu for that matter.
Unlike last year, the flu is circulating widely in Colorado this year, and so are a lot of other common colds.
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.

How Is Slit Administered
The first SLIT dose is always administered in the doctors office, similar to allergy shots. Then patients can take the tablets at home. But epinephrine auto-injectors must be available in case of a severe allergic reaction, or anaphylaxis.
- Patients using SLIT tablets for grass and ragweed pollen should start taking them 4-12 months prior to the start of their pollen season. They should be taken throughout the entire pollen season, for best effectiveness. Tablets for certain grass pollens are available for children as young as 5 years old. Ragweed tablets are for patients 18-65.
- Patients using SLIT tablets for house dust mites should take them year-round. It can take 8-14 weeks of daily dosing to experience a noticeable benefit. The tablets are indicated for patients 18-65 years of age.
Another form of SLIT involves drops of liquid allergen extracts held under the tongue. This is not approved for use in the United States. The treatment is typically not reimbursed by health insurance.
What Is Sublingual Immunotherapy
SLIT tablets approved by FDA treat grass and ragweed pollens and house dust mites. Each SLIT tablet covers one type of allergen.
Allergy tablets may not be the best option for people with multiple allergies as they only treat one at a time. Allergy shots can treat multiple allergens at once.
Also, if you have severe or uncontrolled asthma, you are not eligible to take the tablet.

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.

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.

They’re Not Just For Seasonal Allergies
Allergy shots can be effective for people with hay fever and other seasonal allergies, but they can also work for year-round indoor allergieslike mold, dust mites, and animal danderand allergies to insect bites or stings.
“In the case of stinging insects, the shots can be close to curative,” says Dr. Dziadzio. “That’s the one time I really push people to get the shots no matter what, because it’s such a dangerous allergy.” Allergy shots may also be a good choice for people who don’t like taking medications or can’t avoid the thing they’re allergic tolike a pet or the great outdoors.
Should I Get Allergy Shots
If you suffer from allergies that are not fully controlled by over the counter or prescription allergy medicines or have side effects from taking allergy medicines, allergy shots might be the right choice for you. For some patients, allergy shots are the only option because allergy medicines can interfere with other medications they must take. Allergy shots can also offer a more effective solution to allergies to triggers you are exposed to regularly, such as pet dander and pollen.

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:
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.
Why Do You Need To Know What You Have
Well, Barron said it could help you and your doctors to make decisions on treatment and also helps the state better track transmission of COVID-19.
Obviously COVID impacts you and others around you because of potential infectivity, but so does the flu and so does RSV, actually, those things can all be transmissible to others and make other people really sick, she said. Flu has treatment. So does COVID and we could give you monoclonal antibodies if you were in the right risk groups.
Regardless of what you have, Barron said stay home from work and away from gatherings if you can, and make sure to wear a mask if you do go anywhere or see anyone, and preferably an N-95 or KN-95 mask.

How Long To I Have To Keep Getting My Allergy Shots
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 .
Allergy Shot Schedule For Dogs
Immunotherapy might require your pet to receive injections for the rest of her lifetime, but the time between each injection can vary depending on the dog.
If it’s working, this is typically continued long-term for maintenance, Dr. Harbour said. Sometimes we can decrease the frequency of injections. Typical frequency is every two to three weeks once at a maintenance dose.
Your vet might recommend sublingual immunotherapy instead, which is an oral tablet given to your dog once daily under the tongue.

How Long Do Allergy Shots Last
People who receive allergy shots over a three to five-year span will see a huge improvement in their allergic symptoms for years after discontinuing their shots. Keep in mind that it is still possible for your allergic symptoms to relapse. We will start immunotherapy again for any patients who experience a relapse in their allergic symptoms.
How Can I See My Family And Friends Safely For The Holidays
Gathering with friends and family on Christmas will depend on each persons risk assessment. If everyone is vaccinated and boosted, thats a good scenario, said Barron. She also recommends being careful with elderly loved ones.
If there’s somebody particularly complex either because their medical conditions or their age that you’re worried about, treat them that way, Barron said. Where you can still see them. You can still talk to them, you can give them a quick hug, but maybe you limit the close interactions with them. So there’s droplets coming out, they’re not gonna land on your loved one.
Barron said there are several things to keep in mind during gatherings:
- Make sure there’s good ventilation and air flow, either indoors or outdoors
- Take a rapid COVID-19 test just to be sure
- If you’re not feeling well, skip the party
- And If you travel by plane, train or some other form of group travel and come down with something, be prepared to quarantine in that place for at least 10 days.

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:
- Facial swelling
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.
Aka How To Stop Allergies For Good
If your dog has allergies, it can feel like youre always buying her allergy medicine.
And sometimes, even pricey prescription medications can seem like theyre not helping much.
Thats why some pet parents choose to get allergy shots for their dogs . Its literally the only drug-free method that reduces pet allergies for good which means no more expensive prescriptions.
So, how does it work?
The Dodo reached out to Dr. Lydia Harbour, a veterinary dermatology resident at Dermatology for Animals in Arizona, to find out everything a pet parent of a dog with allergies should know about immunotherapy.

Where Does The Information Come From
Researchers funded by the Agency for Healthcare Research and Quality , a Federal Government research agency, reviewed 142 studies on allergen-specific immunotherapy to treat allergies and/or mild asthma from allergies published between January 1967 and May 2012. The report was reviewed by clinicians, researchers, experts, and the public. You can read the report at www.effectivehealthcare.ahrq.gov/allergy-asthma-immunotherapy.cfm.
What Can I Do To Help Stop A Reaction
At each visit, tell the nurse any new information before you get the shot.
Report anything that happened after your last shot.
Report any new medicines you are taking.
Report any new medical problems or illnesses.
Report any flares of your allergies.
Report any flares of your asthma.
Report if you are pregnant.
Exercise increases your chance of having a serious reaction. You should not exercise for one hour before your shot or for two hours after the shot.

What Risks Are There With Allergy Shots
You may have redness, swelling, or pain at the site of the shot. These symptoms usually start 20 to 30 minutes after the shot and may not go away until the next day.
To make you feel better, put an ice pack on the shot site and take an antihistamine, like diphenhydramine . Sometimes, the amount of your next dose will need to be changed.
If you have a reaction that is bigger than one and a half inches wide, you should tell your doctor. A reaction that lasts longer than 24 hours also should be reported to the doctor.
Life-threatening reactions are rare. These are serious reactions:
Sudden itching of the nose, eyes, throat, ears, or skin
Shortness of breath or wheezing
A lightheaded or dizzy feeling
Tightness in the chest
Hives or itchy palms
Serious reactions most often occur within 30 minutes after the shot. Any of these symptoms should be reported right away. The office where you get your shots can treat these reactions. The treatment will include a shot of adrenalin and an antihistamine. More treatment may be needed.
