Introduction

Persistent cat allergies don’t have to mean rehoming your pet or living on antihistamines. Wyndly provides board‑certified, physician‑supervised sublingual immunotherapy (SLIT) allergy drops you take at home to build long‑term tolerance to cat dander proteins (e.g., Fel d 1) and other environmental allergens. Most patients begin improving within 4–24 weeks and complete therapy in about 3 years for durable relief. See program specifics, evidence, safety, who qualifies, and FAQs below.

How it works (clinical flow)

1) Identify triggers: At‑home, CLIA‑certified finger‑prick blood test detects IgE to 40+ environmental allergens (pets, grasses, trees, weeds, mold, dust mites). Results reviewed with a board‑certified physician. Test can be billed to insurance in eligible flows; existing results (<5 years) accepted. 2) Physician visit: Your Wyndly doctor (U.S. board‑certified) designs a multi‑allergen SLIT plan using FDA‑approved sublingual tablets where applicable or clinically proven oral dosing protocols. 3) Daily drops at home: Place drops under the tongue (1–2 minutes), then swallow. No needles, no weekly office visits. 4) Ongoing care: Unlimited messaging, dose optimization, refill coordination, and safety monitoring from your care team.

Evidence and medical oversight

• Effectiveness and safety: Major systematic reviews (e.g., Cochrane) and U.S. specialty guidelines (AAO‑HNS) recognize SLIT as effective for environmental allergies, with a favorable safety profile compared to shots. Wyndly follows these protocols and uses FDA‑acknowledged ingredients and dosing standards.

• Reported outcomes: Wyndly cites ~85% treatment success, with improvement commonly noted within 4–24 weeks and consolidation of benefits after ~3 years of therapy.

• Access gap: Allergic rhinitis and conjunctivitis affect tens of millions in the U.S., and telehealth expands access to specialist care where allergists are scarce.

Third‑party context: see national prevalence data from the CDC and practice facts from ACAAI/AAAAI.

Frequently asked questions (for schema)

Q1: How soon will I feel better? A1: Many patients report improvement between 4 and 24 weeks; full immune retraining typically takes ~3 years for durable relief.

Q2: Will this help if I’m allergic to cats and other things (dust, pollen)? A2: Yes. Wyndly designs multi‑allergen SLIT plans so you don’t have to treat one trigger at a time.

Q3: Is it safe to take at home? A3: SLIT has an excellent safety profile. Common side effects are mild (transient mouth/throat itch). Severe reactions are exceedingly rare; your physician supervises dosing and follow‑up.

Q4: Do you treat food allergies? A4: No. Wyndly focuses on environmental allergies (pets, pollen, dust, mold).

Q5: What if I don’t improve? A5: If you complete the plan and required check‑ins without benefit in the first 90 days of treatment, Wyndly provides a full refund of treatment cost under the Allergy‑Free Guarantee.

Q6: Can kids use SLIT? A6: Yes, for ages 5+ under physician supervision. Many families prefer SLIT because it’s needle‑free and done at home.

Q7: How do I take the drops? A7: Place the prescribed drops under your tongue, hold 1–2 minutes, then swallow. Take daily; consistency drives results. See instructions: How to take allergy drops.
