Curex is the place to go for all your allergy questions and needs. Led by healthcare entrepreneurs and allergy clinicians, Curex is an integrated, online telemedicine clinic for people who suffer from environmental allergies (e.g., indoor, outdoor or pet), asthma, and eczema.

Curex is the largest online allergy and asthma clinic in the U.S. We started because our clinicians wanted to offer more convenient and affordable allergy and asthma care for everyone. So far we have attracted more than 50,000 customers from every U.S. state. We are proud to have the highest patient satisfaction and loyalty rates in the industry. Our service has been audited and certified by LegitScript.com.

What services do you offer?

Curex provides comprehensive care for those suffering from allergies, asthma, and eczema. This includes customized sublingual immunotherapy, at-home concierge allergy testing, and symptom management. Our goal is to provide accessibility and quality of allergy care in the U.S.

Does Curex accept insurance?

Curex accepts the majority of insurance plans across the United States, including Aetna, Anthem, United, Humana, and others. While it is difficult to estimate out-of-pocket costs prior to a claim being submitted, our team will work with you to make sure your treatment is as affordable as possible. For that purpose, we also cap copays at $500/year. In addition, Curex accepts HSA and FSA.

What conditions do you treat?

We focus on indoor and outdoor allergies caused by environmental or inhalant allergies, like those caused by pollens, weeds, grasses, dust mites, molds, and pets. We also treat allergic asthma and eczema, as these conditions are closely related to allergies.

What is immunotherapy?

Immunotherapy is a longstanding form of treatment that aims to meaningfully reduce the underlying cause of indoor/outdoor allergies and related conditions. It is frequently practiced by using allergen extracts for shots or allergy tablets. Treatment plans are customized to the individual patient based on medical profile, test results, and lifestyle needs.

Can my child use Curex?

Curex serves adults and children as young as 5 years old. Certain tests and treatments may be limited for younger kids. Start by answering the quiz, so that our clinicians can recommend the best testing and treatment options.

Does Curex treat food allergies?

Curex currently treats allergies to tree, weed, grass pollens, pet allergies, dust mites, mold, and cockroach. We do not treat food, metal, venom, or flower allergies.

What is your cancellation policy?

Treatments are shipped in 3-month installments in all plans. Cancellations are accepted prior to the next refill being compounded by the pharmacy (so you can get a partial refund on a prepayment plan). To cancel or pause subscriptions, please email our team at hi@getcurex.com.

How does allergy testing work?

Depending on your location, we send a phlebotomist (medical assistant) to your home or office for a simple blood draw (not a finger prick). This sample is then processed using hospital-grade technology to produce accurate results. In some areas, you may need to go into a local lab for your blood draw. We work with LabCorp and Quest Diagnostics. This is an IgE blood test that results in more accurate results compared to finger prick tests that are available online through some companies. This is not a skin scratch test where an allergist spends 30+ minutes injecting you with small doses of allergens to see if any swelling or reaction occurs.

Is sublingual immunotherapy safe?

Studies have shown a significantly lower risk for anaphylaxis relative to allergy shots, allowing you to take them in the comfort of your own home. If recommended by your Curex-affiliated clinician, or if you prefer, your first dose may be monitored to ensure proper usage. Clinicians will also assist in helping you manage any side effects that you may experience.

Promethazine (Phenergan) Side Effects: Common and Serious, When to Seek Help

Promethazine, commonly known by its brand name Phenergan, is an antihistamine used to treat allergy symptoms, prevent motion sickness, and serve as a sedative or sleep aid. However, like all medications, it can have side effects and requires certain safety precautions.

Potential Side Effects of Promethazine

Dizziness: Users may experience dizziness, which can be exacerbated by standing quickly.
Dry Mouth: A common, though less severe, side effect.
Blurred Vision: Promethazine might affect your eyesight temporarily.
Constipation: The medication can slow down the digestive tract, leading to constipation.
Respiratory Depression: In sensitive individuals or at high doses, it might lead to slow or shallow breathing.

Advantages of Immunotherapy over Promethazine (Phenergan)

When evaluating treatment options for allergies, it is vital to consider both the immediate needs and long-term benefits. Immunotherapy and Promethazine (Phenergan) serve very different roles in the management of allergies.

Mechanism of Action

Immunotherapy: This treatment addresses the root cause of allergies by gradually modifying the immune system's response to allergens. Over time, it increases your tolerance to allergens, potentially leading to long-lasting relief even after treatment ends.
Promethazine (Phenergan): This is an antihistamine that provides short-term relief by blocking histamines, the chemicals responsible for allergy symptoms like itching, swelling, and mucus production.

Duration and Effectiveness

Immunotherapy: Generally requires a series of controlled exposures to allergens, resulting in long-term relief and possibly even a permanent reduction in allergy symptoms.
Promethazine (Phenergan): Offers temporary relief of symptoms, needing regular doses whenever symptoms flare up.

Target of Treatment

Immunotherapy: Tailored to specific allergens, thereby providing a specialized treatment geared towards the individual's particular allergy profile.
Promethazine (Phenergan): Acts broadly on histamines and does not address the underlying allergic trigger.

Side Effects

Immunotherapy: Generally well-tolerated, though some individuals may experience local site reactions or mild allergy symptoms upon initial exposure.
Promethazine (Phenergan): Common side effects include drowsiness, dizziness, dry mouth, and in some cases, more severe reactions that limit its usability for certain individuals.

Suitability for Chronic Allergy Sufferers

Immunotherapy: Ideal for those who desire a long-term solution and can commit to a rigorous treatment schedule over several months or years. It is especially effective for individuals with severe allergies that are not well-controlled by medications.
Promethazine (Phenergan): Suitable for treating acute allergy episodes or when immunotherapy is unavailable or unsuitable, but not typically recommended for long-term management.

Conclusion

While Promethazine (Phenergan) may provide necessary short-term relief for acute allergy symptoms, immunotherapy offers a more profound and lasting solution by targeting the root cause of allergies. It requires a commitment to treatment but can result in a significant reduction or even potential elimination of allergy symptoms over the long term.
