Curex Review: At-Home Allergy Drops and GLP-1 Weight Care

Allergy drops by subscription, and the fine print behind them

Curex sells at-home sublingual allergy immunotherapy on a monthly subscription, with a GLP-1 weight track running under the same account. Self-pay starts at $99 a month, and the caveat travels with it: No prior value was on record. Self-pay (no-insurance) allergy drops subscription is $99/month with no long-term commitment (cancel anytime); this excludes the $39/mo insurance-billed rate and the $4.99 first-month promo code price. Food allergy drops are a separate line at $149/mo.. On the allergy side the drops sit inside that fee, so the medication is not billed on top of it. The trade-offs are just as plain: the drops are prescribed off-label, immunotherapy runs for years rather than one pollen season, and an FDA warning letter issued in 2025 sits on the company’s public record. People who want desensitization without weekly clinic trips get a cheaper, simpler path; people who want fast relief, or a fully FDA-approved product, will not find either one here.

Is Curex legit, and is it FDA approved?

Two separate questions get tangled together in Curex reviews, so take them one at a time.

On legitimacy, this is a real telehealth practice, not a supplement shop. Prescription treatment still requires an evaluation by a licensed clinician, and you cannot buy immunotherapy off a shelf. The company also holds LegitScript certification, a third-party review of licensing, ordering controls and advertising practices that many payment processors and ad platforms require. That certification is a floor, not a gold star, but plenty of grey-market sellers never clear it.

On FDA approval, no telehealth company is FDA approved. The agency approves drugs, biologics and devices. For allergen immunotherapy, FDA has licensed allergen extracts for injection and a small set of under-the-tongue tablets for specific triggers such as grass pollen, ragweed and dust mite; you can see the licensed products on the agency’s allergenics product list. Custom liquid drops mixed for one patient are not in that group. Prescribing them is legal and common in US allergy practice, but it is off-label use, and that single fact explains most of the insurance friction described later.

The other item on the record is an FDA warning letter issued to Curex in 2025. A warning letter is FDA’s formal notice that it believes a company has violated federal requirements. It is not a court ruling and it does not shut a company down, but it is public, it is specific, and it deserves ten minutes of your time before you enroll. We hold that letter against the trust score rather than waving it away; you can see how the weighting works in our scoring methodology.

What the monthly fee buys, and what bills separately

The self-pay route

Self-pay is one recurring subscription. It covers the clinical side and the drops together, which is unusual in telehealth, where a membership fee plus a medication charge is the norm. That structure makes budgeting simple: no per-vial surprise, no dose-based price jump when your prescription is adjusted. The headline figure is published before you hand over card details, which is a genuine mark in its favour.

The insurance route

Consultations can be billed to insurance, and the recurring fee drops when they are. Read that carefully, because the plan fee is not your total. Copays, coinsurance and any unmet deductible sit on top and vary by plan and state. And because the drops themselves are off-label, many plans decline to cover the medication even when they pay for the visit.

If you are weighing the two routes, put both totals side by side rather than comparing the headline fees alone.

The number that actually matters is the multi-year one

Allergen immunotherapy is not a month-long course. Standard practice runs three to five years, as described in Mayo Clinic’s patient explainer on allergy shots and immunotherapy duration. A modest monthly fee multiplied across four years is a serious commitment, and stopping early can waste the money already spent. Work out the annual figure before the first shipment, not in year two.

Cancellation and refunds

This is a rolling subscription, so cancellation terms decide how expensive a change of mind gets. Before you sign up, confirm three things in writing: whether cancellation happens in your account or only by email, whether any notice period applies, and what happens to vials already shipped or already mixed. Custom-compounded allergen drops are made for one person, so a no-refund policy on opened or personalised product is common across the category.

Quick tip: screenshot the cancellation policy on the day you enroll, then save it with your first invoice.

The core service: sublingual immunotherapy for environmental allergies

How the drops work

Sublingual immunotherapy delivers small, repeated doses of the allergen you react to, held under the tongue. Over months, the immune system learns to tolerate that protein, so the same pollen or dust exposure triggers a smaller response. It treats the underlying sensitivity rather than blocking symptoms the way an antihistamine does. MedlinePlus has a plain-language primer on how allergies and desensitization work.

What the evidence supports, and what it does not

Randomized trials support sublingual immunotherapy for allergic rhinitis, and that evidence is strongest for the standardized tablets FDA has licensed. Custom liquid drop mixes have thinner published evidence, partly because formulations differ between clinics and are harder to compare. That does not make drops useless; it makes the honest claim narrower. Expect fewer and milder symptoms over time in a good outcome, not a cure, and not the same certainty a tablet trial provides.

The daily routine

Dosing is a daily habit, taken at home under the tongue. That is the whole appeal: no weekly drive to a clinic, no waiting room, no needle. The cost of that convenience is discipline. Nobody supervises the dose, and an immunotherapy course that is taken half the time does not build tolerance reliably.

Side effects and the line where you stop and call

Most reactions are local and mild: itching or tingling in the mouth, throat irritation, lip or tongue swelling, stomach upset. These usually settle in the first weeks. Serious systemic reactions are rare but real, which is why every FDA-approved sublingual tablet carries a boxed warning about severe allergic reactions and is dispensed with an epinephrine auto-injector, as set out in FDA’s allergenics labelling. Off-label drops carry no equivalent approved label. Ask directly whether a clinician will prescribe an epinephrine auto-injector alongside your drops, and get written instructions for trouble breathing, widespread hives, throat tightness or faintness. Those symptoms mean emergency care, not a support ticket.

Who this track suits

Best fit: adults with confirmed seasonal or dust-mite allergy, whose antihistamines and nasal steroids only half work, and who will not realistically attend a clinic every week for years. Poor fit: anyone with severe or unstable asthma, anyone who has had an anaphylactic reaction, and anyone who needs supervision to stick with a daily medicine.

Pet allergy drops, and the cat allergy question

Cat allergy is one of the most searched reasons people find this company, usually because rehoming the cat is off the table. Immunotherapy is the only treatment approach that targets the sensitivity itself, and cat dander is a standard allergen used in extract-based treatment.

What to expect with a cat or dog in the house

Constant exposure makes pet allergy harder work than a six-week pollen season. Progress tends to be gradual, and it is usually measured in fewer flare days and less medication, not in a switch flipping. Environmental control still matters: keeping the animal out of the bedroom, HEPA filtration and frequent washing all reduce the load your immune system is fighting.

Where drops fall short

If your pet allergy triggers asthma attacks, immunotherapy is an addition to asthma control, never a replacement for it. And if you are reacting to several animals plus pollens plus dust, ask how many allergens go into your mix and whether piling them together weakens the dose of each. That is a fair question, and a clinician should answer it without hedging.

Food allergy: the track to question hardest

The company’s own site advertises drops for food as well as environmental allergens. Treat this track with more care than the rest of the catalogue.

Food allergy reactions can escalate to anaphylaxis quickly, as MedlinePlus explains in its overview of food allergy and emergency response. The FDA-approved routes for reducing food reactions are a peanut oral immunotherapy powder, given under strict clinical supervision with a risk management programme, and an injectable antibody treatment for reducing reactions to certain foods. Sublingual drops for food allergens are not among the approved products, and dose escalation is the riskiest phase of any food desensitization.

If you are considering this, ask who supervises the first doses, what happens if a reaction starts at home, whether an epinephrine auto-injector is prescribed, and whether a board-certified allergist reviews the plan. A remote-only model handling paediatric food allergy would need very convincing answers to those four questions.

Asthma and eczema: support, not substitution

Asthma and eczema care are advertised alongside the allergy service, and that makes clinical sense, since both conditions often ride on the same allergic sensitivities. Treating the underlying allergy can reduce triggers over time.

What it cannot do is replace controller therapy. Asthma needs a written action plan, a reliever inhaler and, for most people, a daily controller, as described in the MedlinePlus asthma overview. Immunotherapy is never rescue treatment. Uncontrolled asthma also raises the risk of a serious reaction to immunotherapy, so a responsible service should assess your asthma control before starting drops, and should say no if it is poor.

Eczema follows a similar logic. Skin barrier care, emollients and prescribed topical treatment do the day-to-day work, as the MedlinePlus eczema resource outlines. Allergy treatment may reduce one trigger among several.

Children’s allergy care and what changes for kids

A dedicated paediatric page sits on the company’s site, aimed squarely at parents who cannot face years of injections with a small child. The appeal is obvious, and drops are far easier to administer at home than shots.

Three things change for children. First, dosing and suitability are age-dependent, so ask what the minimum age is and how the dose is adjusted. Second, adherence becomes a parent’s job, every day, for years. Third, the safety plan matters more: a child cannot always describe throat tightness clearly, so parents need explicit written instructions on what to watch for and when to use emergency care. Ask whether the treating clinician has paediatric allergy experience and whether your child’s paediatrician gets a copy of the plan.

At-home allergy testing and what a result really means

The pathway usually starts with testing at home, then drops built from the results. Business Insider’s reference coverage described the model the same way, as at-home testing followed by sublingual immunotherapy.

Here is the part worth understanding before you read your own results. A blood test measures sensitization, meaning your immune system has made antibodies to a substance. Sensitization is not the same as clinical allergy. Plenty of people test positive to things that cause them no symptoms at all, which is why results have to be matched against your actual history. A test that returns a long list of positives can easily turn into a longer treatment plan than you need.

Ask which allergens made it into your prescription and why each one earned its place. If you already have testing from an allergist, ask whether those results can be used instead of repeating the panel.

The GLP-1 weight track

The second service line is weight care using GLP-1 medicines, sold under the same brand and account. It sits outside the allergy subscription, so treat it as a separate purchase with separate maths.

What to confirm about the medicine and the pharmacy

The first question is whether you are being prescribed brand-name medication or a compounded version, because the price, the supply chain and the regulatory position differ sharply. FDA has published specific guidance on medicines containing semaglutide, including the risks around compounded products and dosing errors. Ask which pharmacy dispenses, whether it is licensed in your state, and how the medicine is shipped and stored. Background on the molecules themselves sits in our semaglutide side effects and dosing and tirzepatide dose escalation explainers.

Titration and follow-up

GLP-1 treatment is a slow dose climb, not a fixed prescription. Doses step up over months to limit nausea, and the schedule should pause when side effects are rough. Ask how often a clinician reviews your dose, how you report side effects between reviews, and whether any lab work is required before you start. A weight programme that never changes your dose and never checks in is selling refills, not care.

Boxed warning and who should not take these medicines

Semaglutide and tirzepatide carry a boxed warning about thyroid C-cell tumours seen in rodent studies. They are contraindicated for people with a personal or family history of medullary thyroid carcinoma, or with multiple endocrine neoplasia syndrome type 2, and they are not for use in pregnancy. Common effects are gastrointestinal: nausea, vomiting, diarrhoea, constipation. Less common but serious risks include pancreatitis, gallbladder disease, dehydration with kidney injury, and low blood sugar when combined with insulin or a sulfonylurea. Severe or persistent abdominal pain means stopping and contacting a clinician the same day. Our GLP-1 telehealth comparison guide covers how different programmes handle monitoring.

What the weight track costs

The allergy headline fee does not cover it. Ask for the full monthly figure before you start, including whether the medicine and the clinical fee are billed separately, and what happens to the price when your dose increases. Dose-linked pricing is common in this category and it turns a cheap first month into a much more expensive sixth month.

How the two service lines compare inside one account

Signing up, step by step

Step 1: complete the online intake

You answer a health questionnaire covering symptoms, triggers, medicines, asthma history and previous reactions. Answer the asthma and anaphylaxis questions precisely. Those are the fields that should slow the process down if your risk is higher.

Step 2: testing

Testing is done at home, and results feed the prescription. If you have recent allergist results, ask whether they can be used instead.

Step 3: clinician review

A licensed clinician reviews the intake and the results, then decides whether treatment is appropriate and what goes into your formulation. Ask for the prescribing clinician’s name and licence state, and ask whether you can message that clinician directly or only a support team.

Step 4: first shipment

Drops arrive by mail with a dosing schedule. Check the labelling on arrival: what is in the bottle, the concentration, the expiry date and the storage instructions. Photograph the label. If anything is unclear, ask before your first dose rather than after.

Step 5: daily dosing

Doses go under the tongue at home, usually on a build-up schedule before settling at a maintenance dose. Take the first dose at a time of day when someone else is around and you are not about to drive.

Step 6: reviews, refills and renewal

Refills arrive on the subscription cycle, and the account bills monthly until you cancel. Diarise a personal review at three and six months: are you using less antihistamine, sleeping better, missing fewer days? Those are the outcomes that justify continuing.

Before any of this, confirm that a clinician can treat patients in your state, since telehealth licensing decides where prescriptions can be written. Delivery removes the travel problem, but it does not remove the licensing one. Other options across the category sit in our telehealth provider directory.

Refills, shipping and getting hold of a human

Day-to-day, the service lives or dies on two things: whether the drops arrive on time and whether someone answers when they do not. Public feedback splits along exactly those lines, with convenience praised and administrative snags driving most of the frustration.

Practical protection is simple. Order or confirm refills before your last bottle is half empty, because a gap in immunotherapy can mean restarting at a lower dose. Keep every shipping confirmation. Use written channels rather than phone calls for anything involving money, so you have a record of what was agreed.

One structural point worth knowing: this model ships its own preparation rather than routing a prescription to a pharmacy you choose, and there is no Surescripts e-prescribing footprint attached to the practice on our tracker. Ask who compounds and dispenses your drops, and ask what happens to continuity if you move to a different clinic later.

Privacy and what happens to your health data

You are handing over a symptom history, test results and, on the weight side, body measurements. That is sensitive information, and telehealth companies do not all treat it the same way.

Care delivered by licensed clinicians is generally covered by HIPAA, which gives you rights over your records, including the right to get a copy. The HHS guide to your health information privacy rights sets out what those rights are. The grey area is the consumer side of the business: marketing analytics, advertising pixels, app usage data and anything you type into a chat widget may sit outside clinical records.

Four things to check in the privacy policy before you upload anything: what categories of data are collected, whether any data is shared with advertising or analytics partners, how to request deletion of your account and records, and how long records are retained after cancellation. If the policy is vague on sharing, ask support to answer in writing.

The trust and safety record

Set the good and the bad next to each other, because both are on the record.

In the plus column: LegitScript certification, a published monthly price that you can see before signing up, prescriptions written by licensed clinicians, and an all-in fee structure that avoids the bait-and-switch pattern where a cheap membership hides an expensive medication bill. Pricing transparency is not a small thing in this category.

In the minus column: the 2025 FDA warning letter, which caps how far we can score trust here regardless of everything else. Read it yourself in the agency’s warning letter database, then judge whether the issues raised are the kind that would affect your own treatment. Also weigh the off-label status of the drops, which is legal but shifts more of the risk assessment onto the prescribing clinician and onto you.

Our community reviews on this page are moderated, not verified, and any incentivised review is labelled as such. Sponsored placement, where it appears anywhere on this site, is labelled and never changes a score or a ranking.

Who gets real value here, and who should look elsewhere

This suits an adult with confirmed environmental or pet allergy who has tried antihistamines and nasal steroids, cannot spare a weekly clinic slot for several years, and wants a single predictable monthly bill. It also suits parents who know their child will never tolerate injections, provided the safety plan is clear and their paediatrician is in the loop. If your insurance covers the consults, the economics improve further.

Look elsewhere if you have severe or poorly controlled asthma, a history of anaphylaxis, or a food allergy that needs supervised escalation. An allergist-run programme with in-person supervision is the safer route in all three cases. Look elsewhere too if you want a treatment that will fix this pollen season, since nothing about immunotherapy is fast, or if the multi-year total is money you cannot commit. Buying one year of a four-year course is close to buying nothing.

Questions worth asking before you enroll

• Which allergens are in my prescription, and what evidence put each one there?
• Will a clinician prescribe an epinephrine auto-injector, and what is my written reaction plan?
• Who compounds and dispenses the drops, and where are they licensed?
• What is the cancellation notice period, and are unopened or unshipped vials refundable?
• If I bill consults to insurance, what is my likely copay, and will the drops themselves be covered?
• On the weight track, is the medicine brand-name or compounded, and does the price change as the dose rises?

If you are switching from an allergist or another telehealth clinic, ask your current provider for a copy of your testing and treatment records, confirm the date your existing prescription runs out, and time the cancellation so you do not sit without doses in between. Then run your own numbers with our cost calculators before you commit to the first year.

Reputation check

Most Curex reviews in the wild come from two places, and they say different things.

Trustpilot’s profile for getcurex.com shows a TrustScore in the 4 out of 5 band, which the platform labels Great, and the recurring praise there is convenience and price. You can read the Trustpilot profile directly, including the negative entries, which is where the useful detail usually lives.

The longer-horizon source is an r/Allergies thread asking patients who are one, two and three years into treatment how it is going. That Reddit discussion of multi-year results is worth reading in full: patients who stayed adherent tend to describe gradual improvement, while the dissatisfaction clusters around expectations of fast relief and around billing or shipping administration. Business Insider’s reference coverage of at-home allergy testing describes the model as sublingual immunotherapy following home testing, which matches how the company presents itself.

None of that is clinical evidence, and none of it offsets the 2025 FDA warning letter. Read the primary sources, weigh the off-label status, and make the call with a clinician who knows your asthma history.
