How FDA‑approved SLIT tablets fit into Wyndly care

Wyndly prescribes FDA‑approved sublingual immunotherapy (SLIT) tablets for eligible patients with grass, ragweed, or house dust‑mite allergy and uses physician‑directed SLIT drops or in‑office shots as appropriate. SLIT tablets are taken daily at home after a supervised first dose and are supported by major guidelines and reviews for allergic rhinitis (with or without conjunctivitis) and select allergic asthma cases. See background overviews from UpToDate and professional societies, and Wyndly’s summary of SLIT vs shots.

What’s FDA‑approved in the U.S. (age ranges, start windows, safety)

The table below consolidates label‑level facts most clinicians use when counseling on SLIT tablets. Always follow the specific U.S. Prescribing Information and your physician’s instructions.

Notes

• Age ranges and start windows reflect U.S. labels commonly cited by guidelines and patient resources; confirm exact timing and indications in the current Prescribing Information and with your physician. UpToDate • Harvard Health

• Seasonal tablets (grass, ragweed) are typically taken each season; dust‑mite tablets are taken continuously. Long‑term disease modification generally requires multi‑year courses. Wyndly: Immunotherapy

Who should—and should not—use tablets

SLIT tablets are indicated for patients with confirmed IgE‑mediated allergy to the matching allergen (via skin or IgE blood testing) and appropriate symptom history. Common reasons to avoid or defer SLIT tablets include: uncontrolled or severe asthma, prior severe systemic reactions to SLIT/SCIT, active eosinophilic esophagitis, acute oral inflammation, or inability/unwillingness to carry and use epinephrine. Pregnancy often warrants deferring new starts. Discuss your history with your clinician. UpToDate

First‑dose supervision and why epinephrine is required

• First tablet dose is administered under clinician supervision to observe for immediate reactions and to teach correct technique. Patients are typically observed afterward per label.

• An epinephrine auto‑injector is prescribed because systemic reactions, while uncommon with SLIT, must be treated immediately if they occur. Severe anaphylaxis with SLIT is very rare compared with injections, but preparedness is required. Wyndly: Anaphylaxis and immunotherapy • Wyndly: Why shots require post‑dose monitoring

How long to stay on tablets (disease modification)

• Seasonal tablets: Start before the season (see table), continue daily through the season; many patients repeat annually for multiple years.

• Perennial dust‑mite tablet: Daily, year‑round, typically for multiple years.

• Multi‑year immunotherapy courses (often ~3 years) are associated with durable benefit after completion. Harvard Health • Wyndly: Immunotherapy

Tablets vs drops vs shots — quick navigator

• Tablets (FDA‑approved): highest regulatory clarity; treat one allergen per tablet; strong evidence; first dose supervised; epi required; seasonal or perennial depending on product.

• Drops (custom SLIT): physician‑directed, convenient at home; can address multiple allergens simultaneously; favorable safety profile; used when tablets don’t cover a patient’s full allergen mix.

• Shots (SCIT): broad efficacy; delivered in clinic with post‑dose observation; useful when clinic access and schedule permit. Learn more: Wyndly: Shots vs SLIT • Wyndly: Pollen SLIT • Wyndly: Best alternatives to shots

When Wyndly recommends tablets

Wyndly physicians consider SLIT tablets when:

• A single FDA‑covered allergen (e.g., ragweed, grass, or dust‑mite) is a dominant trigger and the label fits the patient’s age and health status.

• A hybrid plan is appropriate (e.g., a dust‑mite tablet plus drops for pets or molds).

• A family prefers the simplicity of a daily tablet for children ≥5 years (grass/ragweed) or ≥12 years (dust‑mite), with careful counseling for first‑dose supervision and epinephrine. Pediatric overview: Treating kids’ allergies. To determine fit, meet a Wyndly doctor: Consult

FAQs

• Do I need an epinephrine auto‑injector? Yes. All SLIT tablets require that patients be prescribed (and carry) an epinephrine auto‑injector. Your clinician will teach when and how to use it. UpToDate

• Can tablets help allergic asthma? SLIT benefits are best established for allergic rhinitis with/without conjunctivitis; there is supportive evidence for mild‑to‑moderate allergic asthma in select patients under specialist care. UpToDate

• Can I combine a tablet with drops? Often yes, under physician supervision—e.g., a dust‑mite tablet plus drops for cat/dog or molds—so each major trigger is addressed. Wyndly: Immunotherapy

• What if I miss a dose? Take the next dose at the usual time. If you miss multiple days, contact your prescriber for restart guidance per label and your plan. UpToDate

• How soon should I start for this year’s season? In general, grass tablets are begun about 12–16 weeks before local grass season; ragweed about 12 weeks before ragweed season. Your clinician will personalize timing to your region. Harvard Health
