Curex is a telehealth company that provides allergy immunotherapy, specifically sublingual (under-the-tongue) allergy drops, delivered to your home. Instead of going to an allergist’s office for weekly injections, you take daily drops at home after completing an at-home blood test and a virtual consultation. Plans start at $39 per month, and the full treatment course typically runs 3 to 5 years.
How Curex Works
The process starts with an at-home allergy test kit. Curex ships you an automatic blood collector that takes less than five minutes to use. You prick your finger, collect a small blood sample, and mail it back. The test uses FDA-approved ImmunoCap technology to measure your immune response to a range of common allergens. The panel is customized based on your location and symptoms, and typically covers tree pollen, weed pollen, grass pollen, dust mites, molds, and cat and dog dander. Curex does not test for food allergens through this kit.
Once your results come back, you have a virtual consultation with a clinician who reviews your profile and formulates a custom allergy drop mixture. The drops are then shipped to your home on a recurring basis. You place them under your tongue daily, gradually exposing your immune system to tiny amounts of the allergens that trigger your symptoms. Over time, this trains your body to tolerate those triggers rather than overreact to them.
What Sublingual Immunotherapy Treats
Sublingual immunotherapy targets airborne allergens. The custom drop formulations can include a broad mix of triggers:
- Tree, grass, and weed pollens (including ragweed)
- Dust mites
- Mold spores
- Pet dander from cats and dogs
- Feathers
This makes it a potential option for people dealing with seasonal allergies, year-round indoor allergies, or both. It is not designed for food allergies, though Curex does offer a separate food allergy subscription.
How Drops Compare to Allergy Shots
Traditional allergy shots (subcutaneous immunotherapy) have been the gold standard for decades, so the natural question is whether drops work just as well. A systematic review and meta-analysis published in Frontiers in Immunology compared the two approaches in children with allergic rhinitis and found no significant difference in symptom scores or medication use between the groups. In other words, drops and shots appear to be similarly effective at reducing allergy symptoms.
Where drops have a clear advantage is safety. The same analysis found that treatment-related adverse events were significantly lower with sublingual drops. Allergy shots carry a small risk of serious reactions, including anaphylaxis, which is why they must be administered in a medical office with a waiting period afterward. Drops cause mostly mild, localized side effects like temporary oral itching or tingling that typically resolve on their own. This safety profile is what makes at-home administration feasible.
Timeline for Results
Allergy immunotherapy is not a quick fix. Most patients begin noticing improvement within the first 6 months, but the full course of treatment takes 3 to 5 years. That length is necessary because the goal isn’t just symptom relief while you’re taking the drops. It’s long-term desensitization, meaning your immune system actually changes how it responds to allergens. People who complete the full course often maintain reduced symptoms for years after stopping treatment.
During the early months, many people continue using their usual allergy medications (antihistamines, nasal sprays) alongside the drops. As the immunotherapy takes effect, the need for those medications typically decreases.
Pricing and Insurance
Curex offers several pricing tiers. The Smart Saver Plan for indoor and outdoor allergy drops starts at $39 per month. A self-pay plan runs $99 per month, which includes all consultations with no copays. A food allergy subscription is $149 per month.
Insurance does factor in, but in a split way. Curex accepts most major insurance plans, including Aetna, Anthem, United, and Humana. Clinical consultations are billed to your insurance. However, the monthly subscription fee itself, which covers the immunotherapy drops, shipping, and related costs, is paid out of pocket and not billed to insurance. HSA and FSA accounts are accepted, so you can use pre-tax health savings to cover the subscription cost.
Who Curex Makes Sense For
The primary appeal is convenience. If you’ve been told you’d benefit from immunotherapy but can’t commit to weekly or biweekly trips to an allergist’s office, at-home drops remove that barrier. The time commitment drops from hours per month (driving, waiting, getting the shot, waiting again for observation) to a few seconds each morning.
It also works well for people in areas with limited access to allergists. Since the consultations are virtual and the drops ship nationwide, geography becomes less of a factor. For someone with multiple airborne allergies who wants a long-term solution rather than daily symptom management with antihistamines, immunotherapy through a service like Curex offers a practical path to that goal.
