Allergy shots cant treat all allergies, but they can help those with allergies to several different pollens including grasses, trees, and weeds. They are also beneficial for molds, house dust mites, cockroaches and pet dander.

If you have general insect allergies, including an allergy to yellow jackets, hornets, wasps, bees or fire ant, allergy shots could also be a good option.

If you struggle with seasonal allergies, talk to your doctor or allergist about immunotherapy injections.

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

Insect Venom Allergies: Short

Insect venom allergies are most commonly caused by bee stings and wasp stings. More severe allergic reactions can quickly be treated using an emergency kit. Allergen-specific immunotherapy is often successful in the treatment of insect venom allergies: It can prevent severe allergic reactions.

Insect stings or bites can have unpleasant effects in people who are allergic to them: Within a very short amount of time they can cause swelling around the sting or bite, nausea, dizziness, a rash, breathing difficulties and in rare cases even life-threatening cardiac arrest .

Living with this risk can be frightening. But it’s still important to stay calm if you get stung by an insect that you’re allergic to. Severe consequences are very rare if the medications in the emergency kit are used soon enough.

Unlike many other allergies, insect venom allergies can be treated with allergen-specific immunotherapy . This involves allowing the immune system to gradually get used to the insect venom. Most people who complete this treatment are no longer at risk of having dangerous reactions to the insect venom for a long time afterwards.

Signs Of An Allergic Reaction To The Flu Shot

The risk of having a severe allergic reaction to any vaccine, including the flu shot, is 1.3 in a million. People with an allergy to eggs are most at risk of having a severe allergic reaction, but you may have a reaction to other components of the vaccine, such as preservatives.

However, a preservative allergy is even rarer, and should not deter you from getting the flu shot, says Ryan Steele, DO, board-certified allergist-immunologist and internist at Yale Medicine.

Once you get your flu shot, you may want to monitor your reaction. According to the CDC, some signs of an allergic reaction to the flu shot are:

  • Facial swelling around eyes and mouth
  • Feeling weak

If you experience these symptoms, contact a healthcare provider immediately.

How Can I Prevent An Allergic Reaction

Experiences with allergy shots : Allergies

Allergy shots may help. They’re about 97% effective. Allergy shots for insect stings put tiny amounts of the allergen into your body over time. Your body gets used to the allergen, and if you get stung again, you wonât have such a bad reaction.

Your doctor will first test you to find out what insects youâre allergic to. Then youâll typically get the shots once or twice a week. The dose will go up slightly over time until you reach a maintenance dose, usually in about 3 to 6 months.

For most people, allergy shots are safe. You may have side effects like redness and warmth at the injection site. You could also have a mild or serious allergic reaction to the shot itself. They may be more risky for people who have heart or lung disease or who take certain medications.

What Are The Side Effects Of Allergen

Most people have red and swollen skin at the site of injection. But this reaction dies down during the course of the treatment. Steroid creams or gels can be applied to the skin to reduce these side effects.

Other possible side effects include mild anaphylactic reactions that cause tiredness and headaches. But very severe anaphylactic shock, leading to circulation problems or breathing difficulties, is very rare. If it does occur, it often starts within 30 minutes of the injection. So it’s important to stay in the doctor’s waiting room for at least half an hour after having the injection.

Anaphylactic reactions are more common in people who are having immunotherapy for bee sting allergies: They occur in about 14 out of 100 people who have bee sting allergies, compared to about 3 out of 100 people who have wasp sting allergies.

People with certain heart and immune diseases are more likely to have severe reactions to the treatment.

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 Is Rush Immunotherapy

Itâs a faster way to get to a maintenance dose, but itâs also riskier.

During the first part of the treatment, you get doses of the allergen every day instead of every few days. Your doctor will check on you closely, in case you have a bad reaction. In some cases, you may get medicine before you get the dose of the allergen, to help prevent a reaction.

Reactions Which May Occur To A Weekly Allergy Injection Include But May Not Be Limited To:

How Allergy Vials are Made for Allergy Shots

Delayed Reaction: Some patients develop swelling, itching or bruising several hours and up to three days after injection. This can be minimized by taking a long-acting antihistamine prior to the injection. Examples include: Claritin, Allegra, Clarinex, and Zyrtec.

Large Local Reaction: Immediate or delayed redness or swelling that is larger than a 50 cent piece and lasts more than 24 hours may require icing and taking an antihistamine such as Benadryl . Please avoid driving after taking 50 mgs of Benadryl.

General or Systemic Reaction: These reactions are rare and usually occur within minutes. Potentially very serious symptoms include chest tightness, difficulty breathing, coughing, wheezing, hives, generalized itching or flushing, mouth or throat swelling, fainting or collapsing. The patient must seek immediate emergency medical treatment if these symptoms occur. First, an Epi-Pen should be used to inject epinephrine into the leg. Only then should the patient call 911.

How Should Insect Stings Be Handled

It is always important to be prepared for an anaphylactic reaction in other words, to always have an emergency kit with you if there’s a risk of being stung. The kit contains an adrenaline injection, oral steroid medication in the form of a tablet or liquid, and an antihistamine medication. These allow people to treat their symptoms quickly and effectively themselves.

It’s important to react immediately after being stung:

  • Take just the antihistamine pill at first if the reaction is mild and you don’t have breathing difficulties or circulation problems.
  • Depending on the severity of the skin reaction around the sting, take the steroid medication too.
  • Inform people who are nearby in case the allergic reaction becomes more severe and they have to help.
  • If the allergic reaction causes more serious problems such as breathing difficulties, nausea, circulation problems or swelling in the mouth and throat, it’s important to inject the adrenaline into the thigh muscle as soon as possible.
  • If you are stung by a bee, pull the stinger out within 20 to 30 seconds in order to prevent all of the venom from entering your body. Take care not to pinch the stinger while removing it. Doing so may squeeze more venom into the skin. Instead, scrape across the stinger using a fingernail. This will pull it out.

If your symptoms are severe, it’s a good idea to see a doctor.

There are patient education programs to help people learn how to manage the risk and use the emergency treatment.

What Are Epinephrine Kits

These let you give yourself medicine right away if youâre stung, before you get to a doctor for treatment. The most common brand is an EpiPen. You should still see a doctor ASAP after being stung.

You’ll need a prescription from your doctor to buy one of these kits. Carry two with you at all times. In order to prevent drug interactions, tell your doctor about any medicine you take.

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 .

Allergen-specific immunotherapy can be a helpful long-term treatment. It involves regularly injecting small doses of the insect venom under the skin. A bit like with vaccines, the immune system gradually gets used to the allergen. After a while the body no longer reacts to the insect venom in such an extreme way.

It takes three to five years to complete allergen-specific immunotherapy. In some rare cases, doctors even recommend life-long immunotherapy.

What Are Allergy Shots/allergen Immunotherapy

Allergen immunotherapy is treatment regimen devised to decrease your sensitivity to what you those allergens that cause your symptoms. Your allergen sensitivities have been determined by your skin testing. The process involves subcutaneous administration off increasing quantities of purified natural allergen extracts. The administration is divided into a Build-up Phase and a Maintenance Phase. During the build up phase injections may be one to two times every 7-10 days. This phase typically lasts between 3-6 months and is determined by the frequency of the injections. The goal of the build up phase is to reach the effective therapeutic dose. This dose may vary from patient to patient and is determined by how sensitive you are to the allergen extract and your immune responses during the build up phase. In the maintenance phase the goal is to increase the time between shots to every 2-4 weeks. This will be determined by your symptoms and in consultation with your physician. When new vials are made the level of antigen is very high and thus you will have a short build up phase before going back to your regular schedule. The recommended time for the maintenance phase is between 3-5 years. Immunotherapy has been shown to prevent the development of new allergies and, in children, it can prevent the progression of the allergic disease from allergic rhinitis to asthma. Allergen immunotherapy can lead to the long-lasting relief of allergy.

How Long Does It Take Allergy Shots To Work

Be Safe from Anaphylaxis-Mayo Clinic

Allergy shots have been around for around 50 years and have extensive research to back up their effectiveness. Because immunotherapy teaches your body to have a more measured response to the culprit allergen, the length of time varies based on the severity of the allergey and the pliability of your immune system to learn how to better manage the allergen.

Most patients experience a significant reduction in allergic symptoms within 12 months of initiating therapy, and by three years, many patients no longer have any sensitivity to the substance. Continued high-level exposure to the allergen during treatment may impact the efficacy of the treatment. For example, if you’re getting immunotherapy because you’re allergic to cats and you live with a cat, it may take longer for the immunotherapy to work, if at all.

Twelve months may seem like a long time when you’re accustomed to taking pills that quickly mask symptoms, but the sooner you start immunotherapy, the sooner you can lose the pills and feel better every day. Book online today.

Are Allergy Shots Right For You

Flu shot: Safety, side effects, and facts

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.

How Does Immunotherapy Work

Hint: It’s not like taking the injection form of Allegra. Allergy shots work in a completely different manner compared to over-the-counter or prescription allergy medication. These shots don’t mask symptoms or temporarily block immune responses they can actually fix the cause of your allergies, training your immune system to more effectively manage its response to that allergen.

Unlike medications, immunotherapy is, therefore, completely personalized to your unique allergy. Similar to a vaccine, an allergy shot exposes your immune system to a very small amount of the substance, or substances, to which you’re allergic. Your immune system responds by learning how to handle that allergen without overreacting. It’s this over-reaction of the immune system to “harmless” substances that causes what we call allergies. An allergy-prone immune system is not unlike trying to bug bomb your whole house because of a single housefly instead of simply getting a flyswatter or catching the fly to let it outside.

Are Allergy Shots Effective

When patients follow the protocol for getting allergy shots, they have a success rate of more than 90%. Studies have reported that allergy shots can minimize the occurrence of asthma and prevent emergencies from allergic reactions. Allergy shots continue to work even after the treatment is completed. Allergy shots are even more effective when given to children, because they can actually help to keep new allergies from developing.
