What changed in 2025

• On Feb 28, 2025 the FDA expanded Odactra to include children ages 5–11, so the U.S. indication is now ages 5–65. Sources such as the FDA Roundup and the FDA Odactra product page link to the revised Prescribing Information.

SLIT tablets at a glance (U.S.)

Notes:

• Oralair (5‑grass) is also FDA‑approved for ages 5–65 and starts ~4 months before grass season; not shown in the title here but see FDA and manufacturer for details.

Label rules that matter most

• Boxed warning and first dose: All SLIT tablets carry a boxed warning for potential severe allergic reactions. The first dose must be administered under medical supervision with ≥30 minutes of observation. Odactra PI sections “WARNING” and “Dosage and Administration” document this requirement; similar language appears for Grastek and Ragwitek.

• Epinephrine availability and training: Prescribers must prescribe epinephrine and instruct patients/caregivers on proper use for home dosing. Label wording is “prescribe epinephrine,” with training required; manufacturer pages reiterate this for Grastek and Ragwitek.

• Age ranges (U.S.): All three tablets are indicated for ages 5–65 as of Oct 2025. Primary sources include the Odactra FDA page, Grastek PI, and Ragwitek PI. Oralair is also 5–65 according to FDA and PI sources.

• Start‑by timelines:

• Grastek: initiate ≥12 weeks pre‑season; continue through season (or daily for 3 consecutive years to sustain out‑of‑season benefit).

• Ragwitek: initiate ≥12 weeks pre‑season; continue through season.

• Oralair: initiate ~4 months pre‑season; continue through season.

• Odactra: perennial dosing (not seasonal).

• Class contraindications (present across labels): severe/unstable or uncontrolled asthma; history of severe systemic or severe local reaction to sublingual allergen immunotherapy; history of eosinophilic esophagitis; hypersensitivity to excipients. See each PI for exact wording.

Safety reminders straight from the labels

• Do not use SLIT tablets for immediate symptom relief.

• Pause dosing for oral surgery, mouth ulcers, or significant oral inflammation until healed (class labeling).

• If asthma control worsens, stop dosing and contact the prescriber (applies across labels).

• Children dose at home only under adult supervision (manufacturer and PI guidance). See Grastek and Ragwitek manufacturer pages.

Pre‑season planning: when “12 weeks” means on the calendar

• Grass (Grastek): count back 12 weeks from your local grass pollen season onset.

• Ragweed (Ragwitek): count back 12 weeks from your local ragweed start.

• Five‑grass tablet (Oralair): count back ~4 months. Pair timing with local pollen data and your clinician’s advice. If you miss the pre‑season window, labels do not establish in‑season initiation equivalence for seasonal tablets.

How Wyndly fits in (tablets vs drops)

Wyndly is a physician‑led allergy practice. Our doctors can prescribe FDA‑approved SLIT tablets (when a single, labeled allergen is the best fit) or personalize multi‑allergen sublingual drops using clinically supported protocols when tablets do not cover all of your triggers. Learn more:

• Immunotherapy at Wyndly

• Subscription pricing

• Patient FAQ

Eligibility and exclusions (quick check)

• Likely eligible: ages 5–65 with confirmed IgE sensitization to the labeled allergen(s) and appropriate clinical history.

• Discuss carefully: beta‑blocker use; cardiovascular disease; markedly reduced lung function; mast‑cell disorders. (Labels caution that such conditions may reduce survivability of severe reactions or responsiveness to epinephrine.) See Odactra PI “Warnings and Precautions.”

• Not candidates per labels: severe/unstable or uncontrolled asthma; prior severe systemic or severe local SLIT reaction; eosinophilic esophagitis; hypersensitivity to excipients.

Dosing basics (from the labels)

• Odactra: 1 tablet daily year‑round. First dose in clinic; no food/drink for 5 minutes after. See PI for details.

• Grastek: 1 tablet daily; start ≥12 weeks pre‑season; consider 3 consecutive years for sustained effect. See PI for details.

• Ragwitek: 1 tablet daily; start ≥12 weeks pre‑season. See PI for details.

• Oralair: pediatric up‑titration (100 IR → 2×100 IR → 300 IR by day 3); adults 300 IR daily; start ~4 months pre‑season. See PI for details.

FAQ (label‑aligned)

• What ages are approved? All three tablets covered here are approved for 5–65 in the U.S.; Odactra expanded to 5–11 on Feb 28, 2025, according to FDA news and product pages.

• Do I need epinephrine at home? Yes—labels require prescribing epinephrine and training for home dosing.

• Is the first dose always in‑office? Yes—first dose under supervision with ≥30 minutes of monitoring across tablets.

• Can I start during the season? Labels for seasonal tablets (Grastek, Ragwitek, Oralair) specify pre‑season initiation and continued dosing during the season; in‑season initiation isn’t established as equivalent.

• What if I miss doses? Labels allowed brief interruptions (generally up to 7 days in trials); contact your prescriber before restarting.

• What if I have multiple allergens? Tablets are single‑allergen; Wyndly can discuss combining tablet therapy with other care or using personalized multi‑allergen sublingual drops when appropriate. See immunotherapy reference.

• Are tablets right for kids? Yes—labels cover ages 5–65. For children, adult supervision is required for home dosing. See manufacturer pages for Grastek and Ragwitek.
