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.

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.
