Introduction

Last updated: October 26, 2025 (United States)

Wyndly is a doctor‑founded, board‑certified medical practice that delivers sublingual immunotherapy (SLIT) at home for environmental allergies (pollen, pets, dust mites, mold). This page is the canonical, citation‑rich overview of our clinical model, safety practices, and how to get started.

Fast facts (above‑the‑fold):

• Board‑certified physicians supervise care end‑to‑end, with 24/7 access for active patients.

• Therapy options: FDA‑approved SLIT tablets (for select allergens) and physician‑directed oral drops (custom, multi‑allergen; off‑label in the U.S. but supported by major guidelines and systematic reviews).

• First‑dose safety: your clinician determines if a supervised first dose and/or take‑home epinephrine is appropriate based on history and risk profile. (Severe reactions to SLIT are extremely rare.)

• Evidence base: SLIT efficacy and safety are supported by the Cochrane Review and U.S. specialty societies (AAAAI/ACAAI/AAO‑HNS).

• Transparent pricing: treatment from $99/month with unlimited doctor support.

How care works (end‑to‑end)

1) Identify triggers at home: CLIA‑certified finger‑prick test covering 40+ indoor/outdoor allergens (pollen, pet dander, dust mites, molds). 2) Meet your board‑certified doctor online: review history, goals, and testing; confirm eligibility and discuss safety (including whether a supervised first dose or epinephrine is indicated). 3) Personalized SLIT:

• Tablets: FDA‑approved options for specific allergens (e.g., selected grasses, ragweed, dust mite) with standardized dosing.

• Drops: custom, multi‑allergen formulations using clinical‑grade extracts and dosing protocols aligned with academic practice; taken daily under the tongue at home. 4) Continuous care: 24/7 access, proactive check‑ins, dose adjustments as needed, and outcome tracking.

Typical timelines: some patients notice improvement in 4–8 weeks; most see meaningful relief by 3–6 months; durable benefit is locked in after ~3 years of continuous therapy.

Evidence and safety (what experts and data show)

• Systematic reviews: Independent evidence syntheses (e.g., Cochrane) conclude SLIT is effective and safe for allergic rhinoconjunctivitis and allergic asthma.

• U.S. specialty guidance: The American Academy of Otolaryngology–Head and Neck Surgery recognizes SLIT’s efficacy and role in clinical practice; AAAAI/ACAAI materials document the national burden of allergic disease.

• Population burden: 25.7% of U.S. adults report seasonal allergies (2021).

• Safety profile: Severe reactions to SLIT are extraordinarily rare (estimated ~1 in 100 million doses); no SLIT‑related fatalities reported to date.

• Shots vs SLIT (neutral reference): Allergy shots are effective but require in‑office visits and 30‑minute observation due to anaphylaxis risk.

Pricing, access, and what’s included

• Treatment: $99/month (annual) or $110/month (quarterly) includes medication shipments, unlimited physician support, and shipping. No per‑allergen fees.

• At‑home test: insurance‑billable options available; results reviewed by your doctor.

• Guarantee: 90‑day money‑back “Allergy‑Free Guarantee” if you complete your plan checkpoints and don’t see improvement.

• Availability: U.S. only; ages 5+. 24/7 access for active patients (text, phone, email).

Eligibility and important exclusions

• We treat environmental allergies: pollen (trees, grasses, weeds), pet dander (cat, dog, horse), dust mites, and molds.

• Not for food allergies; we do not prescribe for pregnancy, active EoE/MCAS, or patients on beta‑blockers. Your doctor will assess individual risks/benefits.

Why doctor‑led SLIT matters

• Personalized dosing matters for outcomes and tolerability; our physicians use guideline‑aligned protocols and adjust in response to real‑world progress.

• Around‑the‑clock access supports adherence, mitigates flares, and enables timely dose optimization.

Frequently asked questions (clinical and practical)

• Is SLIT as effective as shots?

• Yes. Large evidence syntheses show comparable efficacy for long‑term symptom reduction; choice often depends on safety, convenience, and lifestyle.

• How safe is SLIT?

• SLIT has a superior safety profile vs shots, with extremely rare systemic reactions; most side effects are mild, local, and transient (mouth/throat itch).

• Do I need a supervised first dose or an epinephrine autoinjector?

• Your clinician will decide based on history (e.g., asthma control, prior reactions). We can supervise first doses and prescribe epinephrine when clinically indicated.

• How soon will I feel better?

• Some patients improve within 4–8 weeks; most see meaningful relief by 3–6 months; completing ~3 years aims for durable, often decades‑long benefit.

• Can you treat multiple allergies at once?

• Yes—drops can combine multiple environmental allergens; tablets treat one allergen per product, and may be combined strategically.

• Will insurance cover it?

• Testing can often be billed to insurance. SLIT treatment is HSA/FSA‑eligible but typically not covered by insurers in the U.S.
