Allergens and antigens are substances that cause all of the symptoms for an allergy sufferer. Most allergy drugs only relieve symptoms, such as sneezing or itchy and watery eyes, on a temporary basis. Our team at Farragut ENT and Allergy has worked hard to offer you a solution that can cure you of your allergies–allergy shots.
What Are Allergy Shots?
Allergy shots, clinically known as subcutaneous immunotherapy (SCIT), have been used for over 100 years. The FDA has approved numerous extracts used for these shots. Patients receive allergy shots when trying to treat allergic conditions affecting the nose, throat, eyes, ears, and lungs. They are effective for heading off reactions to many allergens, including trees, grasses, weeds, molds, dust mites, and animal dander.
How Do Allergy Shots Work?
Allergy testing first confirms which allergens are causing your allergies. Then a small amount of the allergen will be injected into the patient’s arm. Injections are typically given once a week with the potentency increasing over time. After 3-5 years, patients will develop immunity to the allergens, resulting in significant symptoms reduction.
Allergy Shots Candidates
Patients that are allergic to the following are candidates for allergy shots which are effective in heading off symptoms of allergies.
- Dust mites
- Pet dander
- Other typical allergens
At What Age Can You Start Getting Allergy Shots?
Allergy shots may begin as early as age five. This treatment should always be performed by a board-certified allergy specialist. Studies indicate that allergy shots can be safe and effective for school-aged children and teens. Some may develop minor, localized reaction after treatment.
Benefits Of Allergy Shots
Allergy shots are a type of immunotherapy that treats most possible allergens. The allergy shots treat the root cause of the allergy, rather than simply dealing with the symptoms. This is more practical over the long-term.
The goal with shots is to give the patient exposure to the allergen in small doses, gradually increasing the amount over time. Eventually, the patient can build up immunity to an allergen that may have bothered them for decades.
How Long Should I Expect to Receive Allergy Shots?
Patients usually notice a decrease in symptoms during the build-up phase of immunotherapy treatment. More significant improvement can take up to 12 months on a maintenance dose, which patients may continue for 3 to 5 years. Studies indicate that the vast majority of patients who stay on their immunotherapy program as recommended achieve lasting resistance to their trigger allergens.
What Happens if You Don’t Finish Your Allergy Shots?
Immunotherapy works over time and through multiple doses scheduled at regular intervals. Each patient may need a specific number of doses to achieve prolonged resistance to allergens. Patients may stop their treatment at any time during their buildup phase or maintenance phase. However, if they discontinue therapy prematurely, their symptoms will likely return.
Can Allergy Shots Cause Allergic Reactions?
Most people who receive allergy shots do not experience adverse reactions. However, because the shots do contain known allergens, there is a potential for the following:
- Local reactions such as swelling, redness, or irritation on the skin. If a local reaction occurs, it usually does so within hours of receiving the shot, and it usually fades soon after.
- Systemic reactions are much less common than local reactions. These may be more concerning, though, and may include nasal congestion, sneezing, hives, wheezing, chest tightness, or swelling of the throat.
- Anaphylaxis is a rare reaction to allergy shots. Studies indicate that this reaction usually occurs within 30 minutes of treatment, which is why patients remain in the office for that time after their allergy shot.
Patients receiving allergy shots often notice that reactions fade or go away completely when they maintain regular weekly or monthly scheduling for their immunotherapy.
Are There Alternatives To Immunotherapy?
Allergy drops seem to be the best alternative to allergy shots in managing the symptoms of certain allergies. Without immunotherapy, allergy-sufferers may rely on oral medications and exaggerated avoidance to manage symptoms. Immunotherapy can take time, but it offers the best rates of success for prolonged relief.
How Long Does It Take Immunotherapy To Calm My Allergies?
Allergy shots are best when viewed as preventative, not reactive. Most patients start to see some benefit 6-12 months after starting shots and then see more profound benefits thereafter. How effective they are immediately is variable by the patient. These shots aren’t meant to be delivered as instant allergy fixes.
