How they differ

Three ways to get allergy drops

Telehealth, directly. Curex and Wyndly test at home, see you by video and ship drops to your door. Curex treats environmental and food allergies in every state and is the only one of the six with a peer-reviewed study of its own patients; Wyndly treats environmental allergies only.

In-person clinics.Nectar (New York City) and Aspire Allergy & Sinus (Arizona, Colorado, Florida, New Mexico and Texas) test and treat in clinic, and also ship drops. Aspire offers allergy shots and procedures alongside drops.

Through your own doctor. Allergychoices and United Allergy Services work through participating practices: you cannot sign up directly, and price and testing are set by the practice. Ask your primary care physician, ENT or allergist whether they offer either program.

The common ground

How allergy drops are regulated

Personalized allergy drops are made from FDA-approved allergenic extracts — the same extracts used in allergy shots — and are prescribed off-label, a long-standing, legitimate practice. That is true of every provider on this page. A small number of single-allergen sublingual tablets are FDA-approved; see the evidence and guidelines summary.

Before any of them

Who should be seen in person first

Anyone with a history of anaphylaxis, poorly controlled or severe asthma, or a suspected drug allergy should be evaluated by an allergist in person before starting any at-home treatment. See when you need an allergist in person. If you are weighing drops against shots, start with allergy drops vs allergy shots.
