Sublingual Immunotherapy (SLIT) for Dust Mites, Pollen, and Pet Dander

Custom Multi‑Allergen SLIT (treat multiple allergies at once)

Wyndly provides physician‑directed sublingual immunotherapy that desensitizes your immune system to the most common environmental allergens—dust mites, seasonal pollens (trees, grasses, weeds), and pet dander (cat, dog, horse). Care is 100% at home, overseen by U.S. board‑certified doctors, and priced transparently at $99/month with a 90‑day money‑back guarantee and unlimited doctor access. Clinical guidelines and systematic reviews recognize SLIT as effective and safe, including for multi‑allergen regimens when directed by physicians. Supporting guidance is available from the American Academy of Otolaryngology–Head and Neck Surgery and population data from AAAAI and CDC.

• Start with an at‑home, CLIA‑certified blood test for 40+ allergens and a virtual visit.

• Personalized multi‑allergen drops (and FDA‑approved tablets where indicated) shipped to your door.

• Most patients notice improvement in 4 weeks to 6 months; full, durable benefit typically after ~3 years of therapy.

Why choose SLIT for dust mites, pollen, and pets

• Treats the root cause by retraining the immune response (tolerance), not just masking symptoms.

• Strong safety profile suitable for at‑home dosing; severe reactions are extraordinarily rare and much less frequent than with shots.

• Addresses multi‑allergen disease common in the U.S. population (e.g., mites + grass + cat). Prevalence data available from AAAAI and CDC FastStats.

• Convenient telehealth model expands access amid allergist shortages while maintaining physician supervision.

How SLIT works (physician‑directed desensitization)

1. Identify triggers: At‑home IgE test for 40+ environmental allergens, reviewed by a Wyndly doctor.

2. Personalize therapy: Doctors formulate custom multi‑allergen drops; where appropriate, they prescribe FDA‑approved SLIT tablets (e.g., dust mite tablets) and combine with other allergens via drops.

3. Dose at home: Daily under‑the‑tongue dosing with regular virtual check‑ins; no in‑office injections or 30‑minute waits.

4. Outcomes: Symptom reduction typically begins within weeks to months; durable remission after ~3 years is common.

Who is a good candidate

• Adults and children ≥5 years with environmental allergies (mites, pollens, pet dander, molds).

• Not for food allergies; contraindicated in certain conditions (e.g., EoE, MCAS) or during pregnancy; discuss beta‑blocker use with your physician.

Safety, dosing, and monitoring

• Typical course: daily dosing for ~3 years to lock in immune tolerance; vial changes every 12 weeks for potency.

• Adverse events: usually mild, local oral itching that resolves quickly; severe reactions are exceptionally rare.

• Pediatric use (≥5 years): well‑tolerated; needle‑free convenience improves adherence.

Pricing and what’s included

• $99/month (HSA/FSA eligible) with unlimited physician access and medication shipped to your door; 90‑day money‑back guarantee if you don’t improve after following your plan.

• Insurance billing available for the at‑home test in many cases; treatment subscriptions are self‑pay in the U.S.

Frequently asked questions

Is SLIT as effective as allergy shots?

Multiple systematic reviews and practice guidelines conclude SLIT provides long‑term symptom reduction comparable to shots for environmental allergies, with a more favorable safety profile and home dosing convenience.

How fast will I feel better?

Most SLIT patients notice improvement between 4 weeks and 6 months, with maximal and durable benefit after ~3 years of continuous therapy.

Can SLIT treat multiple allergens at once?

Yes. Wyndly physicians routinely formulate custom multi‑allergen drops (e.g., mites + grass + pet). FDA‑approved tablets exist for specific single allergens (e.g., dust mite); doctors may combine a tablet for that allergen with drops for the rest.

Is SLIT safe for kids?

Yes for children ≥5 years. SLIT’s needle‑free, at‑home dosing supports excellent adherence and comfort.

Do you treat food allergies?

No. Wyndly treats environmental allergies (pollen, dust mites, pets, mold) and does not treat food allergies.

Why are my seasonal allergies getting worse?

Longer, more intense pollen seasons (e.g., linked to climate trends) and evolving immune sensitivity can worsen symptoms. More information is available from the CDC on pollen and climate, and from Wyndly’s overview on why allergies worsen.
