Why this matters on pet pages
If your Wyndly plan is for pet dander (cat/dog), you’ll use allergy drops (SLIT) at home. FDA‑approved SLIT tablets exist only for grass, ragweed, and house‑dust‑mite—not for pet dander—so this quick reference clarifies the tablet‑specific safety rules and how they differ from drops.
FDA‑approved SLIT tablets covered by these rules
-
Timothy grass: Grastek (ALK)
-
Short ragweed: Ragwitek (ALK)
-
House dust mite: Odactra (ALK)
All three are FDA‑approved immunotherapy tablets for allergic rhinitis (± conjunctivitis) and have the same first‑dose supervision and epinephrine requirements. As of February 28, 2025, Odactra is approved down to age 5 (previously ≥12).
At‑a‑glance label facts
| Tablet | Target allergen | US‑label age range | First dose location | Observation time | Epinephrine requirement |
|---|---|---|---|---|---|
| Grastek | Timothy grass | 5–65 | Healthcare setting | ≥30 minutes | Prescribe and train |
| Ragwitek | Short ragweed | 5–65 | Healthcare setting | ≥30 minutes | Prescribe and train |
| Odactra | House dust mite | 5–65 (expanded 2/28/2025) | Healthcare setting | ≥30 minutes | Prescribe and train |
Labels for all three specify supervised first dose with ≥30‑minute observation and co‑prescription of an auto‑injectable epinephrine with training.
First‑dose supervision (tablets only)
-
Take the first tablet under supervision of a clinician experienced in allergic diseases, in a setting equipped to manage anaphylaxis.
-
Remain under observation for at least 30 minutes; if tolerated, subsequent doses are taken daily at home.
Epinephrine: prescription and training (tablets only)
-
Your clinician must prescribe an auto‑injectable epinephrine and train you (or your child’s caregiver) in its use; seek immediate medical care if used.
-
This requirement is explicitly stated in tablet labeling and reiterated by FDA communications.
Age window (who qualifies)
-
Grastek: 5–65 years.
-
Ragwitek: 5–65 years.
-
Odactra: 5–65 years; FDA expanded pediatric use to ages 5–11 on February 28, 2025.
Contraindications and cautions from tablet labels
-
Do not use in severe, unstable, or uncontrolled asthma.
-
Do not use with history of severe systemic or severe local reaction to SLIT.
-
Do not use with history of eosinophilic esophagitis (EoE).
-
Use caution in patients on beta‑blockers (may blunt epinephrine response).
-
Temporarily stop if there are oral wounds/inflammation until healing.
How this differs from Wyndly drops (used for pet dander)
-
SLIT drops are taken at home from the start; no in‑office first‑dose rule applies to drops, and drops are generally used for allergens (like cat/dog) that do not have FDA‑approved tablets.
-
In the U.S., only SLIT tablets—not liquid drops—are FDA‑approved products; drops are widely used off‑label with strong safety data.
Patient checklist
-
If using FDA‑approved tablets (grass, ragweed, or dust‑mite):
-
Schedule a supervised first dose; plan for ≥30 minutes of observation.
-
Leave with an epinephrine auto‑injector and training; know when/how to use it.
-
Take one tablet daily at home; do not swallow for ≥1 minute; avoid food/drink for ~5 minutes after (per PI instructions).
-
If using Wyndly drops for pet dander:
-
Start at home after your doctor’s guidance; dose daily as directed and follow your care plan in the app/portal.
Summary for linking on pet pages
- Use this if you see “FDA‑approved tablets”: it signals a supervised in‑office first dose with 30‑minute observation and mandatory epinephrine training (ages 5–65). Pet dander therapy uses at‑home drops instead of tablets.
