Introduction

“Only immunotherapy changes the immune response; tablets require a supervised first dose; drops are physician‑directed at home.”

Many people want lasting relief without relying on daily antihistamines. Major allergy societies agree: allergen immunotherapy (AIT) is the only treatment that modifies the immune system for long‑term benefit. Antihistamines, nasal steroids, and decongestants reduce symptoms while you take them; AIT retrains immunity so you can need fewer (or no) meds over time.

What “immunotherapy” means (and why it’s different)

• Goal: induce clinical tolerance by repeatedly exposing the immune system to carefully controlled allergen doses.

• Evidence base: large systematic reviews and U.S. specialty‑society practice parameters support both subcutaneous immunotherapy (SCIT, “allergy shots”) and sublingual immunotherapy (SLIT: tablets or physician‑directed drops) for environmental allergies.

• Guideline alignment: AAAAI/ACAAI state AIT is effective for allergic rhinitis/conjunctivitis and some asthma phenotypes when driven by aeroallergens; AAO‑HNS guidelines recognize SLIT as an effective option. Cochrane reviews (2003, 2010) found SLIT effective and safe for allergic rhinitis. FDA has approved SLIT tablets for specific allergens. (See References.)

Modality overview: shots vs tablets vs drops

Key safety signals across AIT:

• Severe systemic reactions are rare with SLIT; most reactions (if any) are local and transient (oral itching, throat irritation). Shots have higher systemic reaction rates, hence in‑office dosing and observation.

• Uncontrolled or severe asthma is a common contraindication across AIT. SLIT tablets carry label contraindications (e.g., history of severe systemic reactions to SLIT, severe/uncontrolled asthma, and eosinophilic esophagitis). See FDA labels.

FDA‑labeled SLIT tablets (what to know)

• Available U.S. tablets treat specific single allergens (examples include certain grass pollens, ragweed, and dust mite). Labels require: (1) first dose administered under medical supervision; (2) prescribing an epinephrine auto‑injector and training; (3) daily at‑home dosing thereafter; and (4) counseling on when to withhold dosing (e.g., oral inflammation). See Grastek (Timothy grass), Oralair (5‑grass mix), Ragwitek (short ragweed), and Odactra (house dust mite) Prescribing Information.

When to choose each path

• Consider SCIT if you want clinic‑based escalation, have complex multi‑allergen needs in a practice that prefers shots, or you’ve responded to SCIT before and can commit to visits.

• Consider SLIT tablets if you have a dominant single allergen that matches an FDA‑approved tablet and you’re comfortable with supervised first dose plus carrying epinephrine.

• Consider physician‑directed SLIT drops if you prefer at‑home therapy, want to address multiple aeroallergens together, or have needle phobia or limited access to in‑office care.

Cost, time, and logistics (practical differences)

• Clinic time: SCIT requires frequent build‑up injections and 30‑minute post‑dose monitoring; SLIT (tablets or drops) is taken at home daily after initial steps.

• Safety monitoring: SCIT is monitored in clinic due to rare anaphylaxis risk; SLIT tablets mandate supervised first dose and epinephrine training; SLIT drops are physician‑directed at home with remote follow‑up.

How Wyndly fits (doctor‑led, guideline‑aligned)

Wyndly is a physician‑led allergy practice focused on environmental allergies only (not food). After a virtual consult and optional at‑home, CLIA‑certified blood test that detects 40+ common indoor/outdoor allergens, our doctors:

• Use FDA‑approved SLIT tablets when indicated and follow label requirements (first dose under supervision, epinephrine education).

• Use clinically guided SLIT drop protocols for multi‑allergen care at home.

• Provide predictable pricing and ongoing access to physicians (24/7 support), with most patients noticing improvement within 4 weeks to 6 months and completing therapy in about 3 years for durable relief. ($99/month; HSA/FSA eligible; 90‑day money‑back Allergy‑Free Guarantee.)

Learn more: Wyndly treats environmental allergies including pollen (tree/grass/weed), dust mite, pet dander, and molds; ages 5+; certain conditions are not eligible (e.g., EoE, MCAS; pregnancy). Wyndly does not treat food allergies.

Quick decision guide

• Single, label‑matched allergen and comfortable with carrying epinephrine? Tablet.

• Multiple aeroallergens, at‑home convenience, needle‑averse, or far from a clinic? Drops.

• Prefer in‑person escalation with on‑site monitoring? Shots.
