Allergies & Allergic Reaction Treatment

Sneezing, watery eyes, or congestion can start as simple allergy symptoms — but sometimes, allergies can turn serious quickly. At iCare ER & Urgent Care, our medical providers in Frisco, Forney, and Fort Worth, TX treat mild to severe allergic reactions every day. Because each location offers both urgent care and emergency services under one roof, our team can handle everything from seasonal allergies to life-threatening anaphylaxis in the same visit.

What Are Allergies?

Allergies occur when the body’s immune system overreacts to harmless substances such as pollen, food, or animal dander.
This immune response causes inflammation, irritation, and in some cases, serious airway or circulatory problems that require urgent medical attention.

Common Types of Allergies and Triggers

Seasonal Allergies

Pollen, grass, dust, and mold are common in the North Texas region and often trigger sneezing, itchy eyes, and sinus congestion.

Food Allergies

Reactions to foods like shellfish, nuts, eggs, dairy, wheat, and soy can range from mild stomach discomfort to severe systemic responses.

Animal Allergies

Pet dander from cats or dogs can cause eye irritation, coughing, and skin rashes in sensitive individuals.

Insect Bites & Stings

Bees, wasps, hornets, and fire ants may cause swelling, hives, or more severe breathing difficulties that require emergency care.

Chemical Allergies

Exposure to certain perfumes, lotions, cleaning products, or detergents may result in skin rashes or respiratory irritation.

Medication Allergies

New prescriptions — especially antibiotics — can cause unexpected allergic responses. Always tell your provider if you have medication allergies or past reactions.

Sinusitis and Allergy Connection

Ongoing allergic inflammation can block the sinus passages, leading to painful infections.
Symptoms may include nasal congestion, discolored discharge, headaches, tooth pain, and fatigue.
When symptoms last longer than two weeks, a provider should evaluate whether the cause is allergy-related sinusitis.

When to Seek Medical Attention

Many allergy symptoms can be managed at home with antihistamines or nasal sprays.
However, you should seek prompt evaluation at iCare ER & Urgent Care if you experience any of the following:

  • Difficulty breathing or swallowing

  • Swelling of the lips, tongue, or throat

  • Persistent coughing or wheezing

  • Dizziness, faintness, or rapid heartbeat

  • Widespread rash or hives

  • Vomiting, diarrhea, or abdominal cramping after exposure to a known allergen

  • Sinus pain or congestion lasting longer than a few weeks

These may indicate a severe allergic reaction or anaphylaxis, which can become life-threatening without immediate treatment.


How iCare ER & Urgent Care Treats Allergies

Step 1 – Comprehensive Evaluation

Our providers will review your symptoms, medical history, and potential triggers.
If necessary, we may perform lab testing or imaging to rule out infection or other causes.

Step 2 – Personalized Treatment Plan

Depending on your condition, your treatment plan may include:

  • Medications to reduce allergic inflammation (such as antihistamines, corticosteroids, or decongestants)

  • Nasal sprays, saline rinses, or sinus treatments

  • Observation and supportive care for moderate reactions

  • For severe allergic reactions, emergency medications to stop anaphylaxis and stabilize breathing or blood pressure

  • Referral for allergy testing, immunotherapy, or specialist follow-up as needed

Step 3 – Care Coordination Between Urgent Care & ER

Because iCare ER & Urgent Care houses both services, you’ll be treated at the correct level of care immediately — no transfers or delays.
Mild cases can be managed in urgent care, while severe reactions receive immediate emergency-level attention on site.
