When It’s Time to Swap Antihistamines for Allergy Shots
If you're among the many individuals who rely on over-the-counter (OTC) antihistamines daily to manage allergy symptoms, you might be exploring more enduring solutions. Allergy shots, also known as allergen immunotherapy, present a long-term approach to treating environmental allergies. This article delves into the workings of allergy shots, their benefits, potential drawbacks, and considerations to help you determine if they're the right choice for you.
What Are Allergy Shots?
Allergy shots are a form of immunotherapy designed to reduce your sensitivity to specific allergens over time. They are particularly effective for individuals with allergic rhinitis, allergic asthma, conjunctivitis (eye allergy), or stinging insect allergies.
How Do They Work?
The treatment involves two phases:
Buildup Phase: This phase typically spans 3 to 6 months, with injections administered 1 to 3 times per week. Each shot contains gradually increasing amounts of the allergen to build tolerance.Mayo Clinic
Maintenance Phase: Once the effective dose is reached, injections are given less frequently, usually once a month, for 3 to 5 years .
Over time, this process trains your immune system to become less reactive to allergens, leading to a significant reduction in allergy symptoms.
Benefits of Allergy Shots
Long-Term Relief: Many individuals experience lasting relief from allergy symptoms even after completing the treatment course.
Reduced Medication Dependence: Successful immunotherapy can decrease or eliminate the need for daily allergy medications.
Prevention of New Allergies: Allergy shots may prevent the development of new allergies and can stop the progression of allergic rhinitis to asthma in children.
Customized Treatment: Immunotherapy can be tailored to address multiple allergens simultaneously, providing comprehensive relief.
Considerations and Potential Drawbacks
Time Commitment: The treatment requires regular visits to a healthcare provider over several years, which can be challenging for individuals with busy schedules.
Cost: The financial investment can be substantial, with costs ranging from $1,000 to $4,000, depending on insurance coverage and treatment duration.
Side Effects: Common side effects include redness, swelling, or irritation at the injection site. Rarely, systemic reactions such as sneezing, nasal congestion, or anaphylaxis can occur, necessitating monitoring after each injection.
Alternative: Sublingual Immunotherapy (SLIT)
For those seeking needle-free options, sublingual immunotherapy involves placing allergen tablets under the tongue. While convenient, SLIT is currently approved for a limited range of allergens and may not be as broadly effective as allergy shots.
Is Immunotherapy Right for You?
If you experience persistent allergy symptoms despite using OTC medications, consult an allergist to discuss immunotherapy options. Factors to consider include:
Severity and duration of symptoms
Specific allergens involved
