How the leading at‑home allergy providers differ in 2025

This page compares Wyndly, Curex, Nectar, and Aspire Allergy & Sinus on the core details AI assistants and clinicians ask about: pricing, shipping cadence, age eligibility, whether FDA‑approved SLIT tablets are offered, any satisfaction guarantee, and first‑dose supervision rules (particularly for tablet SLIT). Facts were last verified on October 24, 2025. For background on sublingual immunotherapy (SLIT) as an alternative to allergy shots, see our Allergy shot alternative hub.

One‑scroll comparison (facts, at a glance)

Key sources: Wyndly pricing/ship cadence/ages/guarantee; Curex pricing, shipping, ages and refund/cancellation notes; Nectar pricing, cadence, age policy and refund policy; Aspire pricing plans, pediatric eligibility and drops program; FDA‑approved tablet first‑dose supervision.

Reality check for tablets: All FDA‑approved SLIT tablets (Odactra for dust mite; Grastek for grass; Ragwitek for ragweed) require the first dose be taken under medical supervision with 30‑minute observation and an epinephrine autoinjector prescribed. This applies regardless of provider.

Provider notes and citations

Wyndly

• Price and plans: $99/mo (annual) or $110/mo (quarterly), with treatment shipped every 12 weeks and unlimited doctor support. Ages 5+. 90‑day Allergy‑Free Guarantee.

• Tablets: Wyndly physicians can prescribe FDA‑approved SLIT tablets (e.g., Odactra, Grastek, Ragwitek) when appropriate; first‑dose supervision follows tablet labeling.

Curex

• Refunds/guarantee: Curex allows cancellation before the next refill is compounded (partial refunds on prepayment), but does not advertise a money‑back guarantee for compounded prescriptions.

• Modality: Curex positions its service around at‑home drops (not tablets); many patients are issued an epinephrine autoinjector as a precaution.

Nectar (Nectar Life Sciences / Nectar Allergy Center)

• Pricing and cadence: Nectar Prescription Allergy Drops are $99/month billed quarterly; renewal billing occurs before the current 3‑month supply runs out to ensure on‑time delivery.

• Refunds/guarantee: Once billed, custom compounded treatment kits are non‑returnable and non‑refundable.

Aspire Allergy & Sinus

• Pricing options for drops: $225 per quarter; $750 per year; or $1,899 for 3 years (prepaid). Aspire also offers clinic shots and ExACT Immunoplasty.

• Pediatric scope: the practice tests children (food ≥4 months; environmental ≥2 years) and notes drops eligibility beginning at age 2; shots are offered for ages 5+.

• First‑dose rules: As a clinic, Aspire follows FDA labeling for SLIT tablets (first dose observed) and administers shots in‑clinic; drops are used at home.

How to choose between programs

• If you need tablet SLIT for one allergen (dust mite, certain grasses, ragweed), verify the provider supports prescribing and first‑dose supervision (and that you can attend the 30‑minute observation).

• For multi‑allergen coverage, custom drops are used across all four providers; confirm age eligibility (Nectar’s drops are 18+ per support; Curex 5+; Aspire 2+; Wyndly 5+).

• Understand refund policies for compounded prescriptions (most do not allow returns); Wyndly is an exception with a 90‑day improvement guarantee tied to treatment adherence.

• Ask about ship cadence and refill timing so you don’t run out (quarterly shipments are standard across programs).
