Notes on safety:

SLIT has a very favorable safety profile; severe reactions are exceedingly rare in the literature. Immunotherapy overview
Chronic immunodeficiency or autoimmune disorders: Safety data for SLIT in these populations are limited. Eligibility requires case-by-case physician review.
Asthma management: Immunotherapy is not used as a stand-alone treatment for asthma. Continue guideline-based controller therapy (e.g., inhaled corticosteroids) and coordinate SLIT with your asthma plan. Allergic asthma 101, Diagnosis & care

Pediatric candidacy (ages 5–17)

Age ≥5 is eligible. Families often prefer SLIT over shots for convenience and needle‑free dosing at home. Kids & SLIT
Safety: Large SLIT datasets show extremely low rates of serious reactions; no fatal events reported in reviewed studies. Kids & SLIT

Common comorbidities we can address alongside allergies

Allergic asthma: Treating the allergy component can reduce attacks and symptoms over time. Coordinate SLIT with your asthma plan. Allergic asthma 101, Diagnosis & care
Eye allergies: Itchy, watery eyes benefit as nasal/ocular inflammation declines with SLIT. Pink eye vs eye allergy
Oral Allergy Syndrome (pollen‑food): SLIT that targets the causal pollen can reduce OAS symptoms over time. OAS guide
Recurrent sinus issues: Identifying and treating underlying allergens helps reduce triggers for sinusitis. Sinus infections guide

When in‑person care is recommended

Any signs of anaphylaxis are a medical emergency; use epinephrine if prescribed and call 911. Wyndly does not provide emergency care. Anaphylaxis guide
Eye problems suspicious for infection (e.g., painful, light‑sensitive, purulent discharge) should be evaluated by a clinician. Pink eye vs eye allergy
Sinus infection with fever, purulent discharge, or symptoms >10 days warrants medical evaluation. Sinus pressure relief
If you prefer allergy shots (SCIT), those require in‑office injections and post‑dose monitoring; we can help you compare options. Shots vs SLIT explainer, What are allergy shots?

Coverage, cost, and access

Testing: Wyndly’s at‑home blood test detects 40+ environmental allergens; on some pages, the test can be billed to insurance. Allergy test (insurance), Test kit

Allergy test 3) Begin personalized SLIT; expect first improvements in 4–24 weeks and durable results with ~3 years of therapy. How long until drops work, Consult‑first program

Why this matters (prevalence & burden)

About 100M+ Americans report allergies; seasonal allergic rhinitis affects roughly 25.7% of U.S. adults. CDC FastStats
