How It Works

Allergen immunotherapy (also known as allergy shots) remains the gold standard for treating moderate to severe allergies. Our allergy doctors in Waterbury, CT, design treatment plans tailored to your specific allergens, using annual retesting to refine your care as you progress.

Unlike traditional clinics, which may require weekly office visits for years, our patients benefit from at-home shots and treatment plans that often last just one year.

Phase 1: Build-Up 

Your treatment starts with the build-up phase, during which you will receive allergy shots with progressively higher allergen concentrations. These are usually administered three to four times weekly. Depending on your injection timetable and how well you tolerate the treatment, this phase may last as long as eight months.

• Injections 3–4 times per week
• Doses gradually increased over 6–8 months

Phase 2: Maintenance

Once the build-up phase is finished, your allergist will establish the ideal dose and shift you into the maintenance phase. During this period, injections are typically given about twice per week.

At this stage, you might begin to experience relief from allergy symptoms. If improvements are observed, you will stay in the maintenance phase for approximately four months. Afterward, your allergist will reassess your condition to determine if continuing the injections is necessary.

• Twice-weekly injections for approx. 4 months
• Progress tracked through regular evaluations
