Why first‑dose supervision matters

Updated: November 27, 2025

This checklist prepares families for the supervised first dose of FDA‑approved sublingual immunotherapy (SLIT) tablets (e.g., for grass, ragweed, or dust‑mite allergies). SLIT tablets are an at‑home, needle‑free way to desensitize the immune system after your first supervised dose; they have a strong safety profile compared with shots and are supported by major medical organizations. For background on SLIT and how it compares with shots, see Wyndly’s overview of immunotherapy and safety resources.

What this checklist covers

• Pre‑visit screening and preparation

• What happens during your supervised first dose (including observation)

• Epinephrine auto‑injector training essentials

• Day‑2 and beyond: daily home dosing routine

• When to contact your care team or seek emergency care

• Contraindications and precautions

• State-by-state timing resources and safety links

Before your appointment (pre‑dose screening)

• Confirm you are starting an FDA‑approved SLIT tablet appropriate for your allergen (grass, ragweed, or dust mite).

• Review candidacy and contraindications with your clinician. Wyndly generally avoids SLIT for patients who are pregnant, on beta‑blockers, or with certain conditions (e.g., eosinophilic esophagitis, mast cell activation syndrome).

• Discuss your asthma status. Uncontrolled asthma increases risk of adverse reactions.

• Avoid dosing if you have active mouth ulcers, oral wounds, recent dental procedures the same day, or if you are acutely ill (fever, severe viral illness). Reschedule if needed.

• Review your current medications with your clinician (e.g., beta‑blockers may complicate anaphylaxis management).

• Hydrate; do not eat or drink for 5 minutes before and after the dose unless your clinician advises otherwise.

At the clinic: your supervised first dose

• Verification: clinician confirms the product, lot, expiration, and your identity.

• Baseline check: symptoms, vitals as indicated, asthma control review.

• Administration: place the tablet under the tongue as directed; do not swallow for ~1 minute, then avoid food or drink for 5 minutes (per product instructions).

• Observation: remain under medical supervision (commonly ~30 minutes) so staff can monitor for mouth or throat itching, hives, wheeze, cough, chest tightness, dizziness, or gastrointestinal symptoms.

• Symptom management on site: mild oral itching/tingling is common and usually brief; clinicians manage any progressive symptoms per protocol. For severe reactions, epinephrine is first‑line—review where it is stored and who will administer it.

Epinephrine auto‑injector training essentials (families)

Your prescriber may issue an epinephrine auto‑injector for home use with SLIT tablets. Practice these steps with a trainer device and review your emergency plan:

• Recognize anaphylaxis promptly: trouble breathing, throat/tongue swelling, persistent cough/wheeze, faintness, widespread hives, vomiting, or rapidly worsening symptoms.

• Use epinephrine immediately (do not wait) if anaphylaxis is suspected; inject into the outer thigh through clothing if necessary.

• Call 911 after epinephrine; lie down with legs elevated unless breathing is difficult.

• If symptoms persist or recur before EMS arrives, a second dose may be required per your physician’s plan.

• Store devices at room temperature; check expiration dates.

After you leave (first 24 hours)

• Normal, mild local reactions (mouth or ear itching, throat tickle) often resolve quickly. Avoid hot/spicy foods for several hours if mouth feels sensitive.

• Escalate care if you develop systemic symptoms (worsening hives, chest tightness, wheeze, throat swelling, syncope). Follow the steps above and contact your clinician.

Day 2 and beyond: your daily home dosing routine

• Timing: take your tablet once daily as prescribed. Consistency matters—set phone reminders.

• Technique: place tablet under the tongue; avoid eating/drinking for ~5 minutes afterward per label instructions.

• Activity: avoid strenuous exercise, hot showers, or alcohol for about 1 hour after dosing if you notice they worsen mouth/throat symptoms.

• Oral health: postpone dosing on days with significant oral wounds; notify your clinician if you undergo major dental work.

• Tracking: keep a simple log of doses and any symptoms; share with your care team during check‑ins.

• Follow‑up: Wyndly provides ongoing virtual check‑ins and 24/7 support.

Who should not start SLIT tablets? (talk to your clinician)

• History of severe reactions to SLIT tablets or uncontrolled asthma

• Current use of beta‑blockers, or certain cardiac/medical conditions per your prescriber

• Eosinophilic esophagitis (EoE) or significant active oral inflammation

• Pregnancy (defer initiation; discuss continuation if already on therapy)

• Other contraindications per your physician’s judgment and product labeling

For broader candidacy and alternatives (drops vs. tablets vs. shots), consult your care provider.

Safety snapshot and evidence

• SLIT (drops/tablets) is clinically shown to reduce symptoms long‑term and is generally safer and more convenient than shots for many patients.

• FDA‑approved SLIT tablets exist in the U.S. for certain grasses, ragweed, and dust mites; initiation is typically supervised with observation, with subsequent doses at home.

State timing and safety resources

Use these regional timing guides to plan starts outside peak seasons when practical, and review safety resources with your family.

State guide	Typical peak months (examples)
California	Trees: Mar–Apr; Grass: May; Weeds: Aug–Sep
Oregon	Trees: Mar–Apr; Grass: Jun; Weeds: Sep
Texas	Winter cedar; Spring trees; Fall ragweed
Florida	Year‑round; spring most mixed
New York	Late Feb/Mar–Oct; cat dander common indoors
Ohio	Trees: Apr; Grass: Jun; Weeds: Sep
Maryland	Apr, Jun, Sep worst
Tennessee	Apr, Jun, Sep worst

FAQs (for families)

Q1. What side effects should we expect after the first SLIT tablet dose? A1. Mild, short‑lived mouth or throat itching is common. Persistent hives, wheeze, throat swelling, dizziness, repeated vomiting, or faintness are not typical—use epinephrine and call 911.

Q2. Will we need an epinephrine auto‑injector at home? A2. Your prescriber may provide one and train you on use as part of starting SLIT tablets. Keep it accessible and check expiration dates.

Q3. How soon does SLIT begin working? A3. Many patients notice improvement within weeks to months; durable benefits accrue over 3–5 years of immunotherapy.

Q4. Are SLIT tablets the same as SLIT drops? A4. No. Tablets are FDA‑approved for certain allergens and have specific label instructions (first dose supervised, daily adherence). Custom drops are another sublingual form used under physician guidance.

Q5. Can kids use SLIT? A5. Yes—SLIT is commonly used in children 5+ under clinician supervision.

Q6. What if we miss a dose? A6. Take the next dose at the usual time the following day. If you miss several days or have had a respiratory illness, message your care team for guidance before resuming.

Q7. How do tablets compare with shots for safety and convenience? A7. Both are effective; tablets avoid injections and frequent clinic visits and are generally associated with fewer systemic reactions.
