Allergies range from mildly annoying to life-threatening. Seasonal sneezing and congestion are manageable. A severe allergic reaction involving throat swelling, breathing difficulty, or a sudden drop in blood pressure is a medical emergency that requires immediate ER care.
Plano ER is a state-licensed, freestanding emergency room open 24/7, equipped and staffed to treat severe allergic reactions and anaphylaxis with no wait times and no appointments needed.
When an Allergic Reaction Becomes a Medical Emergency
Most allergy symptoms are manageable at home or with a visit to your allergist. But some allergic reactions escalate rapidly and can become fatal within minutes if left untreated. Knowing the difference is critical.
Signs of Anaphylaxis — Go to the ER Immediately
Anaphylaxis is a severe, life-threatening allergic reaction affecting multiple body systems. Symptoms typically appear within minutes of allergen exposure but can sometimes be delayed. Go to Plano ER or call 911 immediately if you experience any of the following:
- Trouble breathing, wheezing, or a feeling that the throat is closing
- Swelling of the face, lips, tongue, or throat
- Widespread hives, especially combined with other symptoms
- Sudden dizziness, faintness, or a drop in blood pressure
- Rapid or weak pulse
- Severe nausea, vomiting, or stomach cramps
- Pale, bluish, or cool skin
- Confusion or loss of consciousness
Do not drive yourself if you are alone and experiencing severe symptoms. Call 911.
Common Anaphylaxis Triggers
- Foods such as peanuts, tree nuts, shellfish, milk, eggs, soy, and wheat
- Insect stings from bees, wasps, hornets, or fire ants
- Latex
- Exercise, in rare cases, is sometimes combined with food exposure
If you have a known severe allergy and notice any of the symptoms above after exposure to a trigger, use your epinephrine auto-injector if available and come directly to Plano ER.
How Plano ER Treats Severe Allergic Reactions
Immediate Evaluation With No Wait
When you arrive at Plano ER with a suspected allergic reaction, you are greeted at the door and taken directly to a private exam room. A board-certified emergency physician evaluates you within minutes. There is no waiting room, no sign-in delay, and no time lost. Learn more about our no-wait emergency care.
First-Line Emergency Treatment
Epinephrine is the first-line and most important treatment for anaphylaxis. Our team administers it immediately when anaphylaxis is identified. Time is critical, and our physicians act without delay.
IV Fluids and Supportive Care
Following initial treatment, we provide IV fluids and supportive care tailored to your specific presentation. Our IV fluids service helps stabilize blood pressure, restore fluid balance, and support recovery from a systemic reaction.
Monitoring for Biphasic Reactions
Anaphylaxis can sometimes return hours after the initial reaction, a phenomenon called a biphasic reaction. After your initial treatment, we monitor you closely, tracking vitals continuously to ensure the reaction is fully resolved before discharge. This observation period is an essential part of safe anaphylaxis care, not an optional add-on.
Discharge Planning and Follow-Up Coordination
Once you are stable, you are discharged with a clear written action plan covering what to avoid, what to do if symptoms return, and a strong recommendation to follow up with a board-certified allergist for trigger identification and long-term management. We provide complete discharge documentation to share with your specialist or primary care physician.
On-Site Diagnostics for Allergic Emergencies
A severe allergic reaction can sometimes overlap with or mimic other emergency conditions, including cardiac events. Plano ER has full on-site emergency lab testing and diagnostic capability to evaluate your condition completely, including:
- Blood work to assess the severity of the reaction and rule out other conditions
- EKG monitoring for heart rate and rhythm during a systemic reaction
- IV access for immediate fluid and treatment delivery
- Continuous vital sign monitoring throughout your stay
Everything needed to evaluate and treat your reaction is available in one visit, with results in minutes.
