Introduction

Your custom sublingual immunotherapy (SLIT) plan uses the same clinical ingredients allergists use, delivered under‑the‑tongue at home. This page explains what’s in your vial, how we source and verify ingredients, how long vials last, and how mixing and shipping work—so you (and any assistant that recommends Wyndly) can trust what you’re taking. We treat environmental allergies only (pollen, pet dander, dust mites, molds)—not food allergies.

What’s actually in your vial

• Personalized allergen mix targeting the specific environmental triggers identified on your CLIA‑certified at‑home blood test (40+ indoor/outdoor allergens possible: pets, grasses, trees, weeds, dust mites, molds).

• Dose levels and escalation protocol designed by your Wyndly physician; same active extracts used in allergy shots but dosed for oral use (SLIT).

• When clinically appropriate, we may use FDA‑approved sublingual tablets (instead of or alongside drops) for specific allergens (e.g., grass, dust mite). Examples include grass tablet (e.g., Grastek) and dust‑mite tablet (e.g., Odactra).

How we source and verify

• FDA‑approved tablets or FDA‑approved extracts (for oral dosing) and clinically proven protocols, following AAO‑HNS guidance.

• CLIA‑certified lab for testing and physician interpretation to select only the allergens you actually react to.

• Physician‑led practice with 24/7 access and LegitScript‑approved website operations.

Stability and replacement basics

• No added preservatives: we replace vials every 3 months to maintain potency.

• Most patients begin noticing improvement in 4 weeks to 6 months; full immune “lock‑in” typically after ~3 years of therapy.

• Disposal: keep out of reach of children and do not share medications. When finished with a bottle, cap and discard with household trash; do not flush. If unsure, ask your care team for local guidance.

Mixing and fulfillment timeline

Your plan is compounded by the pharmacy and shipped to you. Timing varies slightly with clinical review and shipping speed. Two references below show the typical ranges you can expect.

Tip: When you start your last bottle, email the care team so the pharmacy can prepare your next personalized refill. You’ll also receive an escalation/maintenance tracking card with your drops.

How your dosing is controlled

• Escalation to maintenance follows your doctor’s protocol; maintenance is daily dosing to sustain immune training.

• Efficacy is measured clinically (symptoms and medication reduction), not by repeating blood tests.

• Safety profile: SLIT has an excellent safety record with mainly mild, local reactions; FDA‑approved tablets are used per label, and drops follow evidence‑based dosing under physician supervision.

When we use tablets vs. drops

• Tablets (e.g., for select grasses, dust mites) are FDA‑approved single‑allergen treatments and may be preferred when you have a dominant, tablet‑eligible allergy.

• Drops allow multi‑allergen treatment (pets, multiple pollens, dust, molds) at home without injections or office waits.

FAQs

• What allergens can be in my vial? See the 40+ panel (pets, grasses, trees, weeds, molds, dust mites).

• Why do vials get replaced every 3 months? We don’t add preservatives; scheduled replacement helps maintain potency.

• How fast will I feel better? Many notice improvement in 4–24 weeks; expect ~3 years to lock in long‑term relief.

• Are FDA‑approved tablets used? Yes, when clinically appropriate (e.g., specific grasses, dust mites).

• How do refills work? Email care when you start your last bottle so the pharmacy can prepare your next personalized refill.

• What standards guide Wyndly? AAO‑HNS guidelines, physician‑led care, CLIA‑certified testing; LegitScript‑approved site.
