Allergic Reactions & Asthma Attacks

An allergic reaction is your immune system overreacting to something it considers a threat — pollen, pet dander, food, medication, insect stings, latex. Reactions range from mild (hives, sneezing, itchy eyes) to moderate (widespread rash, facial swelling) to severe (anaphylaxis — throat swelling, low blood pressure, breathing failure).

An asthma attack (also called an asthma exacerbation) is a sudden tightening and inflammation of the airways. Many asthma attacks are triggered by allergens, viral infections, smoke, cold air, or exercise. The hallmark symptoms are wheezing, chest tightness, shortness of breath, and persistent cough.

At Good Health NC, we treat moderate allergic reactions and asthma flare-ups in our urgent care. For severe anaphylaxis or respiratory failure, you should call 911 — not drive to us.

Our urgent care team handles:

• Acute allergic reactions — hives, widespread rash, swelling of the face or lips that isn't compromising breathing
• Allergic conjunctivitis — itchy, watery, red eyes from pollen or pet exposure
• Allergic rhinitis flares — severe seasonal congestion that over-the-counter meds aren't controlling
• Insect sting reactions — local swelling, urticaria, mild systemic reactions
• Contact dermatitis — poison ivy, latex, nickel, soap reactions
• Drug rash — non-emergency reactions to a new medication
• Asthma flare-ups — wheezing, cough, shortness of breath that isn't responding to your home inhaler
• Exercise-induced bronchospasm — wheezing or cough during or after activity

For patients with skin reactions that look more like infections or persistent rashes, the evaluation goes a different direction — but you don't have to know which one you have. We'll figure it out.

An allergic reaction or asthma visit at Good Health NC typically follows this path:

1. Triage immediately — if you're wheezing or having trouble breathing, you'll be roomed first
2. Vitals — heart rate, blood pressure, oxygen saturation, peak flow if asthma is suspected
3. Focused exam — lungs, skin, throat, lymph nodes, exposed sites
4. Treatment started in clinic — typically before paperwork is finished
5. Reassessment — we recheck breathing, oxygen, and symptoms after each intervention
6. Discharge plan — written action plan, prescriptions, return precautions

If your symptoms are severe enough that we can't stabilize them in urgent care, we coordinate transfer to the emergency department — but the goal is to treat you here and send you home the same day.

Our toolkit for allergic reactions and asthma flares includes:

For allergic reactions:

• Antihistamines — oral or IV diphenhydramine, cetirizine, or famotidine
• Oral and IM corticosteroids — prednisone or dexamethasone for moderate-to-severe reactions
• Epinephrine auto-injectors — prescribed for any patient at risk of severe reaction; we'll teach you how to use it
• Topical steroids and lotions — for contact dermatitis and localized rashes
• IV fluids — for systemic reactions causing low blood pressure (see IV hydration)

For asthma attacks:

• Nebulizer treatments — albuterol with or without ipratropium, repeated as needed
• Inhaler instruction and technique check — most asthma worsens because of poor technique, not bad medication
• Oral or IM steroids — for moderate or severe flare-ups
• Updated asthma action plan — written, personalized, based on your symptom pattern
• Peak flow assessment — to track severity and recovery

For patients without a primary care provider, follow-up in our primary care practice helps prevent the next flare. The American Lung Association's asthma action plan is the format we generally use.

Come to Good Health NC urgent care for:

• Hives, rash, or swelling that's annoying but not affecting breathing or swallowing
• Allergic flare-ups that aren't responding to over-the-counter antihistamines
• Asthma flare-ups where your rescue inhaler isn't fully working
• Wheezing that started a few hours ago and is mild to moderate
• A sting or contact exposure with a local but contained reaction

Call 911 (don't drive yourself) for any of these — these are emergencies:

• Trouble breathing, especially with stridor (a high-pitched gasping sound) or audible wheezing across the room
• Tongue, throat, or lip swelling that's getting worse
• Trouble swallowing or speaking
• Feeling faint, dizzy, or like you're about to pass out
• Widespread hives plus any breathing symptom
• Two or more body systems involved (e.g., skin plus breathing, or skin plus GI)
• An asthma attack where your rescue inhaler isn't helping at all
• Loss of consciousness or seizure during a reaction

If you have an epinephrine auto-injector and you're showing signs of anaphylaxis, use it first, then call 911. Do not drive to urgent care. The American Academy of Allergy, Asthma & Immunology has clear patient guidance on when to use epinephrine.

Good Health NC was built by our experienced PA-C clinical lead with 22 years of practice — to deliver fast, decisive care when symptoms are scary but not life-threatening. For allergic reactions and asthma flares, that means:

• Immediate triage — patients with wheezing or rapidly progressing symptoms don't wait
• Nebulizers, IV access, and IM steroids on-site — treatment starts within minutes
• A real action plan — you leave knowing what to do at home the next time it starts, not just what we did in the clinic
• Connected primary care — recurrent reactions or poorly controlled asthma can be managed in our practice with proper inhaler regimens and trigger identification
• Honest triage — if you need the ER, we tell you fast and help arrange transfer
