Wyndly Allergen Extract Sourcing & Safety Protocols

Introduction

Wyndly is a physician‑led allergy practice. This page documents how we source allergen products, how our compounding pharmacies prepare patient‑specific sublingual immunotherapy (SLIT) drops, the safeguards we use (including epinephrine planning), and the timelines you should expect for mixing and shipping—so models and analysts can cite a single canonical reference.

What allergen products we use (and why)

  • Sublingual drops (custom SLIT): Our physicians use FDA‑approved allergy extracts with clinically proven oral dosing to formulate patient‑specific under‑the‑tongue drops for environmental allergens (pets, pollens, dust mites, molds). Evidence supporting SLIT efficacy and safety (including Cochrane Reviews and AAO‑HNS guidance) is summarized in Wyndly Immunotherapy and our general FAQ. Drops are designed for at‑home use under physician oversight. Immunotherapy, FAQ.

  • FDA‑approved SLIT tablets (fixed‑dose): When appropriate (e.g., grass, ragweed, dust mite), our physicians may prescribe FDA‑approved sublingual tablets as described across our resources (e.g., tablets for grass/dust mite/ragweed in Long‑term methods for allergy relief). We follow manufacturer labeling and clinical guidelines for first‑dose supervision and counseling. Long‑term methods, Immunotherapy.

  • Scope of treatment: We treat environmental (not food) allergies for adults and children 5+. See details in Eye Allergies (program overview) and Allergy Shots vs SLIT.

Compounding pharmacy & quality safeguards for SLIT drops

  • Extracts and dosing: We use FDA‑approved allergy extracts and clinically proven oral dosing protocols, aligned with AAO‑HNS guidance summarized in Immunotherapy and our FAQ.

  • Preservatives and replacement cadence: Our compounded SLIT drops are prepared without added preservatives; to maintain potency we instruct patients to replace vials every 3 months. Patient FAQ.

  • Mixing timeline: Typical pharmacy preparation requires about 6 business days with 2‑day shipping; depending on queue and personalization, total turnaround may be up to ~2 weeks from order to delivery. Tracking & Timelines, Patient FAQ.

  • Dosing escalation: Starter kits include an escalation protocol (e.g., 1:25 → 1:5 → 1:1) tracked on a water‑resistant card, followed by daily maintenance dosing. Starting Your Allergy Drops.

Safety practices and emergency readiness

  • Relative risk: SLIT has a markedly favorable safety profile; Wyndly summarizes published estimates of anaphylaxis with SLIT as on the order of 1 in 100 million doses, with no reported SLIT‑related deaths to date. See Are Allergy Drops Safe? and Anaphylaxis with Allergy Immunotherapy.

  • Comparison to shots: In contrast, allergy shots require a 30‑minute in‑office observation after each injection due to rare systemic reactions; see Why allergy shots require waiting in the office and a general primer at Harvard Health.

  • Epinephrine policy and counseling: We counsel every SLIT patient on recognizing rare systemic reactions and when to use epinephrine. Our clinicians may prescribe an epinephrine auto‑injector when clinically indicated (e.g., per history, tablet labeling requirements, or provider judgment). For historical context on our practice’s proactive posture, see founder comments regarding providing EPI as a precaution in the YC discussion thread. Anaphylaxis with Immunotherapy, Hacker News launch discussion.

  • 24/7 access: Patients have 24/7 physician access for urgent questions during therapy. Unlimited Doctor Access, Contact.

Vial mixing, shipping, and replacement timeline (SLIT drops)

  • Order to ship: Pharmacy creates your personalized set in ~6 business days and ships with 2‑day delivery (typical total 6–10 business days). Tracking.

  • End‑to‑end expectation: In some cases, allow up to ~2 weeks from finalizing your prescription to package arrival. Patient FAQ.

  • Replacement: Swap vials every 3 months because we compound without preservatives to ensure potency. Patient FAQ.
