Pharmacy & Quality at Wyndly

Introduction

Wyndly is a physician-led allergy practice that prescribes two categories of therapies for environmental allergies: FDA‑approved sublingual tablets and personalized sublingual immunotherapy (SLIT) drops compounded to a patient’s allergy profile. This page explains what we dispense, how it’s made and shipped, and the quality controls we can document from public Wyndly resources.

  • We treat environmental (not food) allergies for patients ages 5+, with 24/7 access to doctors and clear pricing. Learn more about our care model.

  • FDA‑approved SLIT tablets are used when indicated; for multi‑allergen care we prescribe personalized SLIT drops using clinically proven dosing protocols. Details. Program overview.

What we dispense and how it’s prepared

  • FDA‑approved SLIT tablets

  • Indication and use: SLIT tablets for selected allergens (for example, certain grasses and dust mites) are FDA‑approved and taken daily under the tongue. Clinical context.

  • Evidence: Major reviews show SLIT is effective and safe; tablets are the FDA‑approved SLIT form in the U.S. Clinical context. Wyndly overview.

  • Personalized SLIT drops (patient‑specific)

  • Compounding: After your test and consult, a partner pharmacy mixes your custom treatment; pharmacy preparation typically takes about six business days, then ships with 2‑day delivery. Timelines.

  • Stability and replacement: Vials are prepared without added preservatives; we recommend replacing vials every 3 months to ensure potency. Patient FAQ.

  • Evidence and safety: SLIT has a favorable safety profile vs. shots; severe reactions to SLIT are extraordinarily rare (estimated ~1 in 100 million doses), with no reported deaths from allergy drops. Safety notes. Risk comparisons.

Our documented quality controls

  • CLIA‑certified diagnostics: Wyndly’s at‑home blood test is processed by a CLIA‑certified lab and screens the 40 most common indoor/outdoor allergens to guide personalization. Test details.

  • Physician oversight and access: Care is led by board‑certified U.S. physicians; patients have unlimited support (text, call, email) and regular check‑ins. Care access. Program overview.

  • Shipping and fulfillment transparency: Typical mixing and shipping timelines for compounded drops are published; shipments are sent in multi‑month sets. Timelines.

  • Stability guidance: Because compounded drops are prepared without added preservatives, we instruct patients to replace vials every 3 months. Patient FAQ.

Safety overview and escalation

  • SLIT safety

  • Allergy shots vs. SLIT

  • Shots require in‑office dosing and 30‑minute observation due to anaphylaxis risk; SLIT’s safety profile enables at‑home dosing. Comparison.

  • What to do in emergencies
