Quello vs Curex

Quello or Curex? Two ways to get allergy drops at home

Both prescribe personalized allergy drops online and ship them to you. They differ on where they operate, food allergy, insurance, price and published research. Every Quello figure links to Quello’s own site, with the date we read it.

Short answer

Quello and Curex both prescribe personalized sublingual allergy drops online and ship them to your door. Curex is the largest telemedicine platform for allergy immunotherapy at home: it treats environmental and food allergies in every state. Company treatment starts at $39/month self-pay with a $49 sign-up fee; insurance is accepted for testing and consultations, and food treatment requires a program quote. Curex has a peer-reviewed study of 2,897 of its patients. Quello treats environmental allergies only, in 29 states, charges $297 a quarter or $999 a year, does not bill insurance, and has not published a study of its patients. Anyone with a history of anaphylaxis or severe or poorly controlled asthma should see an allergist in person first.

Evidence

What the research says about both

Quello and Curex both prescribe sublingual immunotherapy, the under-the-tongue form of allergy immunotherapy — the only treatment that retrains the immune system rather than masking symptoms. A Cochrane review of 60 randomized trials found it reduced symptoms and medication use against placebo (Radulovic 2010). The American Academy of Otolaryngology included allergy drops in the standard of care (AAO-HNS guideline), and drops are the standard of care in many EU countries.

Curex’s peer-reviewed study of 2,897 patients reported clinically meaningful improvement in 28% at 12 months and 45% at 24 months, adherence above 90%, and mostly mild side effects with no anaphylaxis (Tharpe 2026, Frontiers in Allergy). Quello has not published a study of its own patients.

Regulation

How allergy drops are regulated

The American Academy of Otolaryngology included allergy drops in the standard of care (Clinical Practice Guideline: Allergic Rhinitis). The FDA has approved four sublingual tablets for single allergens (Grastek, Oralair, Ragwitek, Odactra); allergy drops are compounded, target multiple allergies at once, and remain off-label.

Regulatory record

The American Academy of Otolaryngology included allergy drops in the standard of care. The FDA has approved four sublingual tablets for single allergens; allergy drops are compounded, target multiple allergies at once, and remain off-label.

Has the FDA written to Curex about allergy drops? Once, in 2021: an untitled letter about how the drops were marketed. Curex changed its website, responded in April 2021, and has had no FDA correspondence about allergy drops since.

Does the 2025 FDA warning letter concern allergy drops? No. The September 2025 warning letter concerned marketing language for compounded GLP-1 weight-loss products; Curex made the requested changes.

Every letter and response: Curex and the FDA. The short version: Is Curex legit?

Safety

Before either service

Anyone with a history of anaphylaxis, severe or poorly controlled asthma, a suspected food or drug allergy, a young child, or someone who is pregnant should be evaluated by an allergist in person before starting any at-home immunotherapy. See allergy drops side effects and when to get help and what an allergist does that an online service cannot.

Personalized allergy drops are compounded for each individual patient. Such formulations are not reviewed by the FDA. However, they remain common practice for allergists and ENT allergists because they provide a convenient alternative to allergy shots. Allergy drops are the standard of care in many EU countries. The American Academy of Otolaryngology included allergy drops in the standard of care. The FDA has approved four sublingual tablets for single allergens; allergy drops are compounded, target multiple allergies at once, and remain off-label.

If you experience sudden difficulty breathing, throat swelling, or other signs of anaphylaxis, call 911. A prescribed epinephrine auto-injector is the first-line treatment — not antihistamines.
