Allergies & asthmaAir Purifiers for Allergies: Do HEPA Filters Help?HEPA air purifiers capture airborne particles including pollen, pet dander, and dust mite debris, reducing indoor allergen exposure. They work best as one layer of control alongside source reduction and, for persistent symptoms, medication or immunotherapy. Choosing the right unit size for your room matters more than brand.Allergies & asthma | education Allergies & asthmaAllergic Asthma Triggers: What Sets Off Your SymptomsAllergic asthma is triggered when the immune system overreacts to inhaled allergens — most commonly dust mites, pet dander, mold spores, pollen, and cockroach particles. Allergy testing identifies your specific triggers, and reducing exposure is the foundation of long-term symptom control alongside prescribed medication.Allergies & asthma | education Allergies & asthmaAllergic Contact Dermatitis vs Atopic Eczema: Key DifferencesAllergic contact dermatitis is caused by direct skin contact with a specific allergen your immune system has learned to react to, while atopic eczema is a chronic condition driven by a defective skin barrier and general immune dysregulation. Patch testing identifies the responsible allergen in contact dermatitis.Allergies & asthma | education Allergies & asthmaAllergic Eczema Triggers: What Causes FlaresEczema (atopic dermatitis) flares when the skin barrier is disrupted and the immune system over-responds. The most common triggers are dry skin, heat, sweating, scratchy fabrics, soaps, fragrances, dust mites, pet dander, and stress. In young children, certain food allergens are also a factor.Allergies & asthma | education Allergies & asthmaAllergic Rhinitis vs Sinusitis: How to Tell the DifferenceAllergic rhinitis produces thin, clear nasal discharge with sneezing and itching — driven by an immune reaction to allergens. Sinusitis — usually infectious — causes thick, discolored discharge and facial pressure. Getting the distinction right matters: antihistamines or intranasal corticosteroids treat allergic rhinitis, while viral sinusitis resolves on its own and only bacterial sinusitis may need antibiotics.Allergies & asthma | education Allergies & asthmaAllergist or ENT for Sinus Allergies: Which Specialist?An allergist identifies allergen triggers and manages the immune response with medications and immunotherapy. An ENT focuses on nasal and sinus anatomy, including structural problems that may need surgery. If your nasal symptoms are driven by clear allergen triggers, start with an allergist; if structural obstruction or recurrent infections dominate, an ENT is the better first step.Allergies & asthma | education Allergies & asthmaAllergy Drops vs. Allergy Shots: Which Is Right for You?Allergy shots (SCIT) and sublingual drops or tablets (SLIT) both treat the underlying cause of allergies rather than just suppressing symptoms. Shots are better studied and widely covered by insurance; sublingual products are more convenient because they can be used at home after the first supervised dose. FDA-approved SLIT tablets exist for grass, ragweed, and dust mite allergens.Allergies & asthma | education Allergies & asthmaAllergy Medicine Safe During Pregnancy: What to KnowSecond-generation antihistamines such as loratadine (Claritin) and cetirizine (Zyrtec) are among the most commonly used allergy medications during pregnancy and have a generally reassuring safety record. No medication is entirely without risk in pregnancy, and your clinician should guide any treatment decision — especially in the first trimester.Allergies & asthma | medication Allergies & asthmaAllergy Testing for Children: What Age Is Safe?Allergy testing is safe at virtually any age, including infancy, when there is a clear clinical reason. Skin-prick testing is accurate and safe from infancy onward. Allergy shots are typically started after age five; sublingual drops have been used in younger children. A pediatrician can advise whether testing makes sense for your child.Allergies & asthma | education Allergies & asthmaAllergy Visit Cost Without Insurance: What to ExpectA first allergist visit without insurance typically costs $150–$400 for the consultation alone. When skin prick testing is done the same day, add $200–$500, bringing total first-visit out-of-pocket costs to roughly $350–$900. Prices vary by location, clinic type, and the number of allergens tested.Allergies & asthma | billing Allergies & asthmaAnaphylaxis Symptoms and Signs: How to Recognize ItAnaphylaxis is a severe, potentially life-threatening allergic reaction that typically begins within minutes of allergen exposure. It involves multiple body systems simultaneously — commonly hives and flushing on the skin, throat tightening and wheezing in the airways, and dizziness or low blood pressure in circulation. Early epinephrine is the critical first treatment.Allergies & asthma | education Allergies & asthmaAnaphylaxis Throat Swelling: Emergency Action StepsThroat swelling that tightens your airway after allergen exposure is anaphylaxis — a life-threatening emergency. Use an epinephrine auto-injector (EpiPen) immediately if available, then call 911 and stay on the line. Do not wait to see if symptoms improve on their own.Allergies & asthma | emergency Allergies & asthmaAspirin and NSAID Allergy: Safe Pain Relief OptionsIf you are allergic or sensitive to aspirin and NSAIDs such as ibuprofen and naproxen, acetaminophen (Tylenol) is the most widely recommended alternative for mild to moderate pain. Whether a reaction to one NSAID predicts reactions to others depends on your specific reaction pattern — a clinician can help you determine what is safe.Allergies & asthma | medication Allergies & asthmaAsthma Action Plan: What It Is and How to Get OneAn asthma action plan is a one-page written guide divided into green, yellow, and red zones based on symptoms or peak flow readings. It specifies which medications to take in each zone and when to call for emergency help. Your clinician fills it out with your specific medications and triggers.Allergies & asthma | records Allergies & asthmaAsthma Attack: What to Do Step by StepDuring an asthma attack, use your rescue inhaler (albuterol) — two puffs, wait 20 minutes, and repeat if needed. If symptoms are severe, worsen rapidly, or do not improve after two rounds, call 911. Always follow a written asthma action plan that specifies what to do in green, yellow, and red zones.Allergies & asthma | education Allergies & asthmaAsthma During Pregnancy: Safe Management GuideTreating asthma during pregnancy is safer than leaving it uncontrolled. Uncontrolled asthma reduces oxygen delivery to the baby, raising the risk of preterm birth, low birthweight, and preeclampsia. Most inhaled asthma medications are appropriate to continue in pregnancy. Always consult your care team before changing any medication.Allergies & asthma | education Allergies & asthmaAsthma Inhaler Prior Authorization Denied: What to DoIf your insurance denied prior authorization for an asthma inhaler, you can appeal — and many appeals succeed. Common denial reasons include step therapy requirements and missing documentation. Your prescribing clinician leads the appeal; peer-to-peer review is often the most effective step. Act quickly, as most plans have strict deadlines.Allergies & asthma | billing Allergies & asthmaAsthma Inhaler Types Explained: Rescue vs. ControllerAsthma inhalers fall into two main types: rescue inhalers (commonly albuterol), which give fast relief during symptoms, and controller inhalers (inhaled corticosteroids), which reduce airway inflammation daily to prevent symptoms. Most people with persistent asthma need both. Combination inhalers contain both in one device.Allergies & asthma | education Allergies & asthmaAsthma Symptoms in Adults: How to Recognize AsthmaThe classic symptoms of asthma in adults are wheezing, chest tightness, shortness of breath, and cough — especially at night, in the early morning, or triggered by exercise, cold air, or allergens. Symptoms vary and may come and go. Asthma can begin at any age; many adults are first diagnosed after age 40. Breathing tests confirm the diagnosis.Allergies & asthma | education Allergies & asthmaAsthma When Exercising: Symptoms, Causes, and TreatmentShortness of breath, wheezing, or chest tightness starting during or just after exercise and resolving within 30 minutes is called EIB. It affects up to 90% of people with asthma and up to 20% of athletes without asthma. Most people with EIB can keep exercising with the right management plan.Allergies & asthma | education Allergies & asthmaBest Allergy Medicine for Adults: What to KnowThe three most commonly used non-drowsy antihistamines for adults are cetirizine (Zyrtec), fexofenadine (Allegra), and loratadine (Claritin). All are second-generation antihistamines causing less drowsiness than older options. Response varies between people — no single option is best for everyone. Nasal steroid sprays may be more effective for nasal symptoms.Allergies & asthma | medication Allergies & asthmaBiologic Medications for Severe Asthma: What to KnowBiologic medications are injected or infused treatments that target specific immune pathways driving severe asthma. Used when inhaled corticosteroids and standard controllers are insufficient, approved options include omalizumab (Xolair), dupilumab (Dupixent), mepolizumab (Nucala), and benralizumab (Fasenra). An allergist or pulmonologist prescribes and monitors them.Allergies & asthma | medication Allergies & asthmaCan Allergies Cause Vertigo or Dizziness?Allergies can cause dizziness and unsteadiness mainly through sinus congestion and Eustachian tube dysfunction that disrupts ear pressure. True vertigo — a sensation of the world spinning — is more often caused by inner ear conditions like BPPV or Meniere's disease. Allergies may worsen these conditions but are rarely the sole cause.Allergies & asthma | education Allergies & asthmaChronic Hives Treatment: What Works When Antihistamines Don'tHives that recur daily or near-daily for six weeks or more are called chronic urticaria. When OTC antihistamines are insufficient, prescription-strength antihistamines, add-on therapies, and — for persistent cases — the biologic omalizumab (Xolair) are effective options. An allergist or dermatologist manages ongoing treatment.Allergies & asthma | seek-care Allergies & asthmaCold-Induced Asthma: Why Cold Air Triggers SymptomsCold, dry air is one of the most consistent asthma triggers. Breathing it irritates and narrows the airways, causing coughing, wheezing, and chest tightness — even in people whose asthma is otherwise well controlled. Covering the mouth and nose with a scarf, using a rescue inhaler before going outside, and reviewing your asthma action plan for winter can reduce flare-ups.Allergies & asthma | education Allergies & asthmaDust Allergy vs Cold: How to Tell the DifferenceDust allergy (allergic rhinitis from indoor allergens like dust mites) and the common cold share sneezing, runny nose, and congestion — but differ in duration, pattern, and associated features. Allergy symptoms persist for weeks to months and lack fever; colds resolve in 7–10 days. Perennial symptoms that are worst in the morning or in the bedroom suggest dust mite allergy. An allergist can confirm sensitization with skin or blood testing.Allergies & asthma | education Allergies & asthmaEosinophilic Esophagitis (EoE): Symptoms & DiagnosisEosinophilic esophagitis (EoE) is a chronic immune-mediated condition in which eosinophil-rich inflammation narrows and stiffens the esophagus, causing difficulty swallowing and food impaction. Diagnosis requires endoscopy with biopsy (≥15 eosinophils per high-power field). Treatment options include dietary elimination, topical swallowed steroids, proton pump inhibitors, and — for refractory cases — biologic therapy.Allergies & asthma | education Allergies & asthmaFood Allergy Diagnosis: How Allergists Test & ConfirmFood allergy diagnosis begins with a thorough medical history, supported by skin-prick tests or specific IgE blood panels. Neither test alone confirms allergy. The oral food challenge — a supervised exposure to the suspect food under medical observation — is the definitive gold standard for confirming or ruling out food allergy.Allergies & asthma | education Allergies & asthmaFood Allergy Symptoms After Eating: What to Look ForTrue food allergy symptoms appear within minutes to two hours of eating and include hives, lip or tongue swelling, vomiting, stomach cramps, and in severe reactions, throat tightening and difficulty breathing. Digestive-only symptoms appearing hours later are more consistent with food intolerance than IgE-mediated allergy.Allergies & asthma | education Allergies & asthmaFood Allergy Testing for Adults: Your Options ExplainedAdults can be tested for food allergies through skin-prick tests and specific IgE blood panels ordered by a physician or allergist. Neither test alone confirms allergy — an oral food challenge, performed under supervised medical observation, is the most definitive option. At-home food sensitivity tests are not validated for diagnosing IgE-mediated allergy.Allergies & asthma | seek-care Allergies & asthmaHay Fever vs. Allergic Rhinitis: Are They the Same Thing?Hay fever and allergic rhinitis are two names for the exact same condition. 'Hay fever' is the older popular term; 'allergic rhinitis' is the clinical name. Both describe an immune nasal response to inhaled allergens — pollen, dust mites, or pet dander — causing sneezing, runny nose, congestion, and itchy eyes.Allergies & asthma | education Allergies & asthmaHives All Over Body: Causes, Types & TreatmentHives (urticaria) are itchy, raised welts caused by histamine release from skin mast cells, triggered by allergic reactions, infections, medications, physical factors, or unknown causes. Most acute hives resolve within days. Chronic hives lasting more than six weeks require medical evaluation to identify the underlying cause.Allergies & asthma | education Allergies & asthmaHow Accurate Are Blood Tests for Allergies?Allergy blood tests — specifically specific IgE tests, sometimes called RAST tests — measure IgE antibodies to detect sensitization to many allergens. They are reliable but not perfect: a positive result does not always mean you will have symptoms in real life. Clinical interpretation by an allergist or clinician is essential for accurate diagnosis.Allergies & asthma | education Allergies & asthmaHow Do Allergy Shots Work? Immunotherapy ExplainedAllergy shots (subcutaneous allergen immunotherapy) work by gradually introducing increasing doses of your specific allergens, slowly retraining the immune system to tolerate rather than overreact. The build-up phase involves weekly injections for about a year; the maintenance phase continues monthly for three to five years, with meaningful benefit typically starting within the first year.Allergies & asthma | education Allergies & asthmaHow Much Do Allergy Shots Cost Without Insurance?Allergy shots (subcutaneous immunotherapy) without insurance typically cost $800–$1,500 per year during the maintenance phase. The initial build-up phase — with more frequent visits — adds significantly to first-year costs. Total out-of-pocket depends on the number of allergens, visit frequency, and clinic pricing.Allergies & asthma | billing Allergies & asthmaHow to Find an Allergist Near You Accepting New PatientsTo find an allergist near you, search your insurance plan's provider directory, ask your primary care clinician for a referral, or use the American Academy of Allergy, Asthma and Immunology's Find an Allergist directory at allergist.aaaai.org/find. Many allergists accept new patients with or without a referral depending on your insurance plan. A first visit typically runs 60–90 minutes and may include skin-prick testing the same day.Allergies & asthma | scheduling Allergies & asthmaHow to Prevent Accidental Peanut Exposure & Manage Peanut AllergyPreventing peanut allergy reactions requires strict avoidance, a written anaphylaxis action plan, and carrying two epinephrine auto-injectors at all times. Vigilant label reading, safe eating-out practices, and educating those around you are the foundation. FDA-approved peanut OIT (Palforzia) is an option for eligible children and adolescents aged 4–17.Allergies & asthma | education Allergies & asthmaHow to Reduce Dust Mite Exposure at Home for AllergiesDust mite levels can be reduced significantly — though not eliminated — by using allergen-impermeable mattress and pillow covers, washing bedding weekly in hot water, and reducing soft furnishings. These bedroom-focused steps, combined with appropriate medication, meaningfully reduce dust mite allergy symptoms.Allergies & asthma | education Allergies & asthmaHow to Use an EpiPen (Epinephrine Auto-Injector)To use an EpiPen: pull off the blue safety cap, press the orange tip firmly against the outer thigh (through clothing is fine), hold for 10 seconds, then remove and massage the site. Call 911 immediately after every use — epinephrine buys time, but emergency care is still required.Allergies & asthma | education Allergies & asthmaHow to Use an Inhaler With a Spacer — Step by StepA spacer is a hollow chamber that attaches to a metered-dose inhaler (MDI) and holds the medication mist so you can inhale it slowly and fully. Using a spacer correctly delivers two to three times more medication to the lungs compared to inhaling directly from the inhaler alone. The technique takes about thirty seconds once learned.Allergies & asthma | education Allergies & asthmaInsect Sting Allergy: How Serious Is It?Most insect sting reactions are local and resolve in a few days. A true venom allergy, however, can cause anaphylaxis — a rapid, potentially life-threatening systemic reaction. Anyone who has experienced hives elsewhere on the body, throat tightening, dizziness, or breathing difficulty after a sting should be evaluated by an allergist. Venom immunotherapy is highly effective at reducing future severe reaction risk.Allergies & asthma | education Allergies & asthmaLatex Allergy Symptoms and What to AvoidLatex allergy is an immune reaction to proteins in natural rubber latex. Symptoms range from a localized itchy rash to hives, runny nose, and rarely anaphylaxis. Healthcare workers, people with spina bifida, and those with banana or avocado allergy face the highest risk. An allergist can confirm the diagnosis with appropriate testing.Allergies & asthma | education Allergies & asthmaMold Allergy Symptoms in Your House — Signs and TreatmentMold allergy causes hay-fever-like symptoms — sneezing, runny or stuffy nose, itchy eyes, and cough — that persist for weeks or months, worsen in damp rooms like basements or bathrooms, and improve when you leave the moldy environment. Unlike a cold, mold allergy symptoms do not resolve within a week or two.Allergies & asthma | education Allergies & asthmaNasal Steroid Sprays for Allergies — Do They Work?Intranasal corticosteroid sprays — including fluticasone (Flonase), mometasone (Nasonex), and budesonide (Rhinocort) — are considered the most effective single medication for allergic rhinitis by clinical guidelines. They reduce nasal congestion, sneezing, runny nose, and eye symptoms, with most improvement seen after one to two weeks of consistent daily use.Allergies & asthma | medication Allergies & asthmaNickel Allergy from Jewelry — Rash, Causes, and Safe MetalsNickel is the most common cause of allergic contact dermatitis worldwide. Jewelry that consistently leaves a red, itchy, or blistered rash — especially at earring sites, watch buckles, or jeans buttons — is the hallmark.

The hallmark: breathing that improves on weekends and vacations. Early removal from exposure dramatically improves outcomes; an occupational medicine physician and allergist or pulmonologist confirm the diagnosis.Allergies & asthma | education Allergies & asthmaOral Allergy Syndrome — Why Raw Fruit Makes Your Mouth ItchOral allergy syndrome (OAS), also called pollen-food allergy syndrome, causes itching, tingling, or mild swelling in the lips, mouth, or throat within minutes of eating raw fruits, vegetables, or nuts. It occurs when immune cells mistake food proteins for similar pollen proteins. Symptoms are usually mild and self-limiting.Allergies & asthma | education Allergies & asthmaPet Allergy Symptoms: Cats, Dogs, and Living With DanderPet allergy symptoms — sneezing, runny or stuffy nose, itchy watery eyes, and skin reactions — are triggered by proteins in pet saliva, urine, and skin flakes (dander), not fur itself. Most people with pet allergies can manage symptoms with environmental changes, antihistamines, and in some cases immunotherapy.Allergies & asthma | education Allergies & asthmaPositive Allergy Test Results: What They MeanA positive allergy test — skin prick or specific IgE blood test — means your immune system has made antibodies to a substance, known as sensitization. Sensitization is not the same as a clinical allergy: many people test positive but have few or no real-life symptoms. Results must be interpreted alongside your actual symptom history.Allergies & asthma | education Allergies & asthmaRagweed Allergy: Fall Season Symptoms and How Long It LastsRagweed is the leading cause of fall allergy symptoms in the US, releasing pollen from late August through October and peaking in mid-September in most regions. Symptoms — sneezing, runny nose, itchy eyes, and nasal congestion — mirror spring hay fever but arrive with the change of season.Allergies & asthma | education Allergies & asthmaSeasonal Allergy Symptoms: Allergies vs. a ColdSeasonal allergies — hay fever or allergic rhinitis — cause sneezing, runny or stuffy nose, and itchy watery eyes that correspond with specific pollen seasons. Unlike a cold, they do not cause fever and last weeks rather than days. Identifying which season and pollen is triggering symptoms makes management far more targeted.Allergies & asthma | education Allergies & asthmaShellfish Allergy: Can You Still Eat Fish?A shellfish allergy does not automatically mean you are allergic to finfish like salmon or tuna — they are biologically unrelated with different trigger proteins. Some people are independently allergic to both. Kitchen cross-contamination is a real risk. An allergist can determine your exact allergy profile with testing.Allergies & asthma | education Allergies & asthmaWhen Does Spring Allergy Season End? Tree and Grass PollenSpring allergy season in the US typically runs from February through June. Tree pollen peaks between March and May, followed by grass pollen from May through July in most regions. The exact timing depends on your location, and tracking local pollen counts helps you time medications and outdoor activities effectively.Allergies & asthma | education Allergies & asthmaWhere to Get Allergy Testing Near YouAllergy testing is performed at allergist and immunologist offices.
