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.

Key Symptoms of Nitrates Allergy

Skin Rashes

One of the common symptoms of a Nitrates allergy includes skin rashes. The skin becomes red, itchy, inflamed, and irritated, often forming blisters or hives. This is a reaction by the immune system to the presence of nitrates.

Respiratory Problems

Individuals with Nitrates allergies often face respiratory issues. These may include difficulty in breathing, wheezing, coughing or shortness of breath. Such symptoms arise due to the allergen affecting the respiratory tract.

Swollen Eyes or Face

Exposure to nitrates can also lead to the swelling of the eyes, face or other parts of the body. This swelling, or edema, is caused by inflammation in response to the allergen, and could be accompanied by redness or discomfort.

Abdominal Pain and Digestive Issues

Abdominal pain, vomiting, and diarrhea are also common symptoms when a person allergic to nitrates consumes foods or drinks containing this compound. This happens due to the system's inability to process and properly digest nitrates.

Dizziness and Fainting

In some cases, people with a nitrates allergy might experience symptoms such as dizziness or even fainting spells. These symptoms occur due to a sudden drop in blood pressure following exposure to nitrates.

Anaphylactic Shock

In extreme cases, exposure to nitrates can cause an immediate and severe allergic reaction known as anaphylactic shock. This can involve a rapid pulse, loss of consciousness, and even death if not treated promptly. It is a medical emergency and requires immediate attention.

How to Recognize if You're Allergic to Nitrates

Understanding Nitrates Allergy Symptoms

Swelling: A common symptom of nitrate allergy is swelling of the skin or other parts of the body.
Rashes: Skin rash or hives could indicate an allergic reaction to nitrates.
Stomachache: A severe stomach ache after consuming foods containing nitrates could suggest an allergy.
Difficulty Breathing: Some individuals may experience difficulty breathing, shortness of breath, or chest tightness.

Evaluating Your Exposure to Nitrates

Nitrates are commonly found in several types of foods and drinks, such as processed meats (hot dogs, sausages, ham), some cheeses, and certain types of vegetables (spinach, celery, beetroot). Evaluate your diet to see if it includes these foods or drinks.

Consulting a Health Care Provider

If you have been experiencing the above symptoms especially after consuming foods or drinks containing nitrates, you should consult your healthcare provider. They may suggest an allergy test to diagnose a nitrate allergy.

Note

It's important to acknowledge that though nitrate allergy is rare, it can occur. Due to its uncommon nature, it may be mistaken for other food allergies or intolerances. A correct diagnosis by a health professional is crucial for proper management and treatment.

When Nitrates Grows and Its Impacts

Nitrates, a form of nitrogen found in organic materials and often used in fertilizers, are present throughout the year but their levels may vary depending on certain factors. They generally tend to rise in conjunction with agricultural cycles.

Spring and Summer

Rainfall: Rain tends to wash nitrates into bodies of water, raising their levels. This often happens during the spring and early summer rainy seasons. Therefore, nitrate levels can be higher in these seasons.

Farming Season

Agricultural activities: Nitrates are heavily used in fertilizers which are most often applied during the planting season. Therefore, periods of intense agricultural activity, such as the farming season, usually coincide with an increase in nitrate levels.

Winter

Runoff: In winter, snowmelt can wash accumulated nitrates into bodies of water, resulting in an increase in nitrate levels.

Where Nitrates Grows Across the USA?

Nitrates do not naturally 'grow' in the environment. They are a type of chemical compound that is found in various forms, often as nitrate salts. Nitrates are commonly used in fertilizers and can be found in high concentrations in agricultural areas across America, where they may contaminate groundwater supplies.

Sources of Nitrates

Agricultural Runoff: Areas with intensive farming, particularly in the Midwest, can have high nitrate levels in the soil and groundwater due to the use of nitrate-based fertilizers.
Industrial Waste: Nitrates can also be found in industrial waste and may contaminate ground and surface water in areas near industrial facilities.
Public Water Supplies: In some urban areas, public water supplies may contain elevated levels of nitrates because of contamination from agricultural runoff or industrial waste.

Tips for Avoiding Nitrates Allergy

‍

Avoid processed foods

One of the most common sources of nitrates is processed foods, particularly processed meats like bacon, sausages, ham, and hot dogs. By reducing your intake of these foods, or even cutting them out completely, you can significantly lower your nitrate consumption.

Choose organic products

Organic fruits and vegetables are less likely to contain nitrates than their non-organic counterparts because the use of synthetic fertilizers, which are a common source of nitrates, is not allowed in organic farming. Therefore, opting for organic products can help you avoid nitrates exposure.

Drink filtered water

Nitrates can seep into groundwater and contaminate the water supply, especially in agricultural areas where nitrates are often used as fertilizers. By choosing to drink filtered or bottled water, you can reduce the risk of consuming nitrates through your water supply.

Grow your own produce

If you have the resources, growing your own fruits and vegetables is a great way to control what goes into your food. You can avoid using fertilizers with nitrates, and as a result, significantly lower your nitrate consumption.

Diet to Ease Nitrates Allergy Symptoms

Consuming a balanced diet with a focus on whole foods can help to alleviate symptoms of nitrates allergy. Here are some food recommendations you should consider:

Eat Fresh Fruits and Vegetables

Organic Produce: Opt for organic fruits and vegetables whenever possible, as these are less likely to have added nitrates. These include apples, bananas, oranges, and leafy greens like spinach and kale.
Homegrown Produce: Growing your own fruits and vegetables will offer control over what goes into your food.

Consume Whole Grains

Brown rice, oats and whole wheat: These are naturally nitrate-free and are a great source of fibre. They also help in maintaining a healthy gut.

Include Proteins without Nitrates

Fresh Meats: Most fresh, unprocessed meats are nitrate-free. This includes fresh beef, chicken, and fish.
Vegetable Proteins: Foods like legumes, chickpeas and lentils are a great source of protein and are nitrate-free.

Moderate use of Dairy and Fats

Unprocessed Dairy: Natural dairy products such as milk, cheese, and yogurt that don't have added nitrates can be included in moderation.
Healthy Fats: Opt for fats from plant sources like avocados, nuts, olive oil as they are nitrate-free.

Remember, drinking plenty of water to stay hydrated and using fresh ingredients to prepare meals can also assist in managing nitrates allergy. Always check labels for any added nitrates or preservatives.

What Food Worsens Nitrates Allergy

Nitrates are components that are often used in the preservation of food, particularly in meats and processed foods. If you have a sensitivity or allergy to nitrates, consuming foods with high nitrate content can exacerbate your symptoms. Here are the foods that should be limited or avoided if you have a nitrates allergy:

Foods High in Nitrates

Processed Meats: Products such as ham, bacon, sausages, salami, hot dogs and other deli meats can have high concentrations of nitrates.
Cured or Smoked Foods: Food items that are cured or smoked, like cured bacon and smoked fish, often contain nitrates for preservation.
Certain Vegetables: Vegetables such as celery, lettuce, spinach, beetroot, radishes, and carrots naturally have high nitrate levels. However, if your symptoms are primarily due to added nitrates in food processing, you may be able to tolerate these.
Processed Foods and Fast Foods: Pre-packaged foods, canned goods, and fast foods often contain nitrates. Check labels for ingredients, as they may include "nitrates" or "nitrites."

In addition to these specific foods, it is also advisable to limit your overall intake of processed and fast food and focus on a diet rich in fresh fruits, vegetables, lean proteins, and whole grains.

Important Note

Always consult with your healthcare provider or a dietitian if you suspect an allergy or sensitivity to nitrates. They can provide guidance and personalized advice to help manage your symptoms and avoid potential triggers.

Allergy FAQ

‍

How do nitrates in medications affect individuals with nitrate allergy?

Effects of Nitrates on Allergy Sufferers

Individuals with a nitrate allergy may experience various symptoms upon exposure, such as headaches, dizziness, skin rashes, or breathing difficulties, depending on sensitivity levels.

Nitrates in medications can unknowingly trigger allergic reactions, so those with known allergies should avoid these medications and consult healthcare professionals for alternatives.

Always communicate with medical practitioners about allergies to ensure safe and effective treatment, especially when prescribed new medications.

Can food preservatives containing nitrates trigger an allergic reaction?

Can Nitrates Trigger Allergic Reactions?

Nitrates in food preservatives are not typically allergens in the traditional sense; they don't cause true allergic reactions, which involve the immune system.

However, some people may experience sensitivity or intolerance to nitrates, leading to symptoms like headaches, skin flushing, or a runny nose.

It’s important to differentiate these reactions from allergies, as they don't involve an immune system response.

Are there alternative agricultural products to avoid nitrates for allergy sufferers?

Alternative Agricultural Products

**Organic Produce:** Opt for organic fruits and vegetables, grown without synthetic fertilizers, which may contain nitrates.

**Grass-Fed Meats:** Consider grass-fed beef and poultry, as these animals are less likely to be exposed to nitrate-rich feed.

**Wild-Caught Fish:** Choose wild-caught fish instead of farm-raised, which can be subject to nitrate exposure through feed.

**Home-Grown Vegetables:** Grow your own vegetables using compost and natural soil amendments instead of chemical fertilizers.
