What “starting treatment” and “improvement” mean

Safety, Trust, and Emergency Plan (SLIT)

This page is Wyndly’s canonical Guarantee & Safety policy. You can find it anytime via the site‑wide footer link: “Guarantee & Safety.”

What SLIT is

Sublingual immunotherapy (SLIT) exposes your immune system to very small doses of your allergy triggers under the tongue to build long‑term tolerance. Major reviews (e.g., Cochrane) and guidelines (AAO‑HNS) support SLIT as effective and safe, with outcomes comparable to allergy shots but without injections or weekly office visits (learn more).

Common, expected side effects

Mild mouth or throat itching, tingling, or irritation shortly after dosing. These typically resolve quickly and can often be reduced by taking an antihistamine if advised by your physician (FAQ).

Serious reactions are rare—but be prepared

Severe reactions to SLIT are extremely rare (estimated around 1 in 100 million doses) and no deaths have been reported in the literature for SLIT (safety details, anaphylaxis risk).
Emergency plan: If you experience signs of a severe reaction (trouble breathing, throat swelling, wheezing, faintness/rapid heartbeat, or feeling like you may pass out), use epinephrine immediately if prescribed and call 911. After emergency care, notify Wyndly at care@wyndly.com or text 720‑730‑9988. Wyndly does not provide emergency services.

Who should not use SLIT (program safety criteria)

We treat environmental allergies only (not food allergies). SLIT is for patients ages 5+ in the U.S.
Contraindications include eosinophilic esophagitis (EoE), mast cell activation syndrome (MCAS), pregnancy, or certain medications (e.g., beta blockers). Your Wyndly physician will screen for these during your consult (eligibility FAQ).

Ongoing support and adverse event reporting

You have 24/7 access to a physician for urgent clinical questions; text 720‑730‑9988 or email care@wyndly.com. Report any side effects promptly so your physician can adjust your plan.

Refunds and undelivered shipments

If you follow your plan, complete required check‑ins, and don’t improve within 90 days of starting treatment, eligible SLIT treatment fees are refunded under this guarantee. Processed test kits and shipped medicines already delivered are not refundable; undelivered medication shipments are refunded as noted above.
Starting treatment: the date you begin taking your SLIT as directed by your Wyndly physician.
Improvement assessment: your Wyndly physician considers your symptom reports and medication use during scheduled check‑ins. Reduced symptoms and/or reduced reliance on rescue meds generally indicate improvement.
