Understanding Allergy Shots & Immunotherapy
Allergy shots—also called allergy immunotherapy—are a process in which gradually increasing doses of allergens are administered over time to build tolerance and reduce allergic symptoms. Rather than masking symptoms, they work by retraining your immune system to respond more mildly to common allergens like pollen, dust mites, mold, and pet dander.
At Allergy Asthma & Sinus Center, we offer allergy shots to help patients in Leesburg, VA gain long-term relief from seasonal and year-round allergies.
Who Benefits from Allergy Shots?
Allergy immunotherapy is often recommended when:
- You continue to experience bothersome allergy symptoms despite standard therapies (antihistamines, nasal steroids, avoidance).
- You have allergic rhinitis, allergic asthma, or significant environmental or pet allergies.
- You desire to reduce reliance on medications and achieve more natural control.
- You are healthy enough (no contraindications) and committed to a multi-year treatment schedule.
Your allergist will review your medical history, allergy test results, and goals to see whether you are a candidate for immunotherapy.
Benefits of Allergy Shot Therapy
- Significant reduction or elimination of seasonal allergy symptoms.
- Ability to use fewer medications over time.
- Potential to prevent the development of new allergies or asthma.
- Long-lasting relief—often years after completing therapy.
- Improved quality of life—with fewer flare-ups, less congestion, and more comfort.
Typical Allergens Treated
In our clinic, we commonly treat allergens for allergy shots, such as:
- Tree, grass, and weed pollens
- Dust mite species
- Animal dander (cats, dogs)
- Mold spores
Your immunotherapy plan is highly personalized—only those allergens to which you test positive will be included in your treatment mix.
How Allergy Shots Work
- Build-Up Phase
You receive injections with gradually increasing allergen doses, typically 1–2x per week, over several months until you reach the maintenance level. - Maintenance Phase
Once the target dose is reached, injections are spaced out (often every 2–4 weeks). This phase may last 3-5 years or more, depending on your response and goals.
Over time, your immune system adapts, reducing overreaction to allergens and producing lasting symptom relief.
Safety & Monitoring
Our allergy shot protocol is conducted under medical supervision with built-in safeguards:
- Doses are administered in the office and observed for a short time post-injection.
- Clinic staff are trained to manage rare systemic reactions.
- Your overall health, asthma status, and medication regimen will be monitored.
- Adjustments are made if needed — dosing may be reduced or paused temporarily in response to illness or side effects.
With proper oversight, allergy immunotherapy is considered a safe and effective long-term treatment.
