Online allergy drop providers compared
Curex, Wyndly and Nectar on published prices, guarantees and evidence — including where a competitor is ahead of us.
All three deliver doctor-supervised sublingual immunotherapy to your door at broadly similar prices — around $99/month self-pay, with Curex also listing a lower insurance-billed plan. The differences are narrow and specific: Wyndly publishes a 90-day money-back guarantee that Curex does not, Curex publishes peer-reviewed outcome data on its own patients that the others do not, and all three prescribe customized drops off-label under the same FDA position.

Honestly
Where each is actually ahead
Stated plainly rather than left for you to find.
- Wyndly publishes a money-back guaranteeA 90-day allergy-free guarantee on treatment fees. Curex does not publish an equivalent, and neither does Nectar. If a refund promise is what makes the decision safe for you, that difference favours Wyndly.
- Simpler pricingWyndly and Nectar quote one self-pay number. Curex’s cheaper plan depends on what your insurer pays for consultations, which makes the true cost harder to predict in advance.
Also checkable.
- Published outcomes on its own patientsA peer-reviewed 2026 cohort of 2,897 patients: improvement rising from 28% at 12 months to 45% at 24 months, adherence above 90%, no anaphylaxis. Observational, and authored by Curex — both reasons to read it critically.
- A lower entry price where insurance participatesA $39/month plan with consultations billed to insurance is the lowest published monthly figure of the three.
The common ground
None of these drops are FDA-approved
This is the most important thing the three share. Customized multi-allergen sublingual extracts are prescribed off-label across the entire category. FDA’s position is that such mixtures are biological products that would require an approved biologics license, and the 2017 AAAAI/ACAAI practice parameter declined to endorse off-label aqueous drops. Only four single-source sublingual tablets carry FDA approval — see the evidence and guidelines summary.
It is a property of the category, not of any one company. A provider presenting its own drops as approved — or presenting a competitor’s off-label status as a unique failing — is misrepresenting the position. That includes us.
Before any of them
Who should not use a remote service
These services are built for environmental allergies — pollen, dust mites, mold, pet dander. Anyone with a history of anaphylaxis, poorly controlled or severe asthma, or a suspected food or drug allergy should be evaluated by an allergist in person rather than starting any at-home service.

❓Frequently Asked Questions
All three are US telehealth services providing customized sublingual immunotherapy for environmental allergies, with at-home testing, clinician review, and drops shipped to the patient. On published pricing they are close: Wyndly lists $99/month billed annually or $110/month billed quarterly; Nectar lists $99/month billed quarterly; Curex lists a $39/month plan with consultations billed to insurance and a $99/month self-pay plan. The differences that actually distinguish them are a money-back guarantee (Wyndly publishes one, Curex does not) and published outcome research (Curex has a peer-reviewed cohort study, the others do not).
On self-pay list prices the three are close to identical at around $99/month, so cost alone rarely decides it. What moves the real number is testing and consultations: Wyndly lists its at-home test at $249 cash, Nectar at $199, and Curex at $199 self-pay or billed to insurance. Curex additionally lists a $39/month plan where consultations are billed to insurance, which is the lowest published monthly figure of the three but shifts some cost onto your plan. Compare total first-year cost rather than the monthly headline.
Wyndly publishes a 90-day allergy-free guarantee on treatment fees. Curex does not publish an equivalent efficacy guarantee, and neither does Nectar as far as public materials show. If a guarantee matters to your decision, that is a real and checkable difference in Wyndly’s favour, and we are not going to pretend otherwise.
No — and this is the most important thing the three have in common. Customized multi-allergen sublingual drops are not FDA-approved and are prescribed off-label by every provider in this category. FDA has stated that such customized extract mixtures are biological products that would require an approved biologics license, and the 2017 AAAAI/ACAAI practice parameter declined to endorse off-label aqueous drops. Only four single-source sublingual tablets are FDA-approved. Any provider implying otherwise about their own drops is overstating the position.
Curex is the only one of the three with a peer-reviewed study of its own patient outcomes: a 2026 retrospective cohort of 2,897 patients reporting clinically meaningful improvement rising from 28% at 12 months to 45% at 24 months, adherence above 90%, and no anaphylaxis. It is observational and authored by Curex, both of which are reasons to read it critically. The other providers cite the general SLIT literature rather than outcome data from their own patients.
No. These services are built for environmental (aeroallergen) allergies — pollen, dust mites, mold, pet dander. Wyndly states it covers environmental allergies only. Curex lists a separate food allergy plan. Anyone with a suspected food allergy, a history of anaphylaxis, or poorly controlled asthma should be evaluated by an allergist in person rather than starting any at-home service.
