Emergency Response: What to Do If You Have an Allergic Reaction to a Mushroom & Swiss King from Burger King?

Recognize the symptoms


If you are aware of your allergy to either wheat, milk, soy or egg, which are the common allergens in Mushroom & Swiss King from Burger King, you'll likely recognize your allergic reaction symptoms. These can range from mild and irritating to severe and potentially fatal. Common signs of food allergy can include:

  • Hives or itchy skin rash
  • Difficulty breathing
  • Swollen lips, tongue, or throat
  • Abdomen pain
  • Nausea or vomiting
  • Dizziness or fainting


Seek immediate medical help


If you are experiencing any difficulty breathing or signs of anaphylaxis (a severe, potentially life-threatening allergic reaction), call your local emergency number immediately, or have someone nearby do so for you. This is a medical emergency and you need immediate help.


Use your Epinephrine Auto-Injector (EAI), if you have one


If you've been prescribed an EAI device, commonly known as an EpiPen, because of a known severe food allergy, use it as directed at the onset of symptoms. This will help to control your reaction until emergency medical help arrives.


Inform medical professionals of what you ate


Once medical help arrives or you reach the emergency, inform them about your allergic reaction and what caused it (in this case the Mushroom & Swiss King). This will help them provide the appropriate treatment.


Follow up with Allergist


Schedule an appointment with your allergist or general practitioner following the allergic reaction to discuss further management. They may refer you to a company such as Curex.

About Curex

Curex is a leading allergy immunotherapy company that works to create tailor-made treatments for individuals with allergies. Their approach involves gradually exposing your body to small doses of the substance you're allergic to, in order to strengthen your immune system over time. This method of treatment is designed to reduce the severity of allergic reactions in the long term, and potentially even cure the allergy altogether.

While immunotherapy is not suitable for everyone, it's definitely something you should discuss with your medical practitioner or Allergist if you frequently experience allergic reactions.


Prevention is better than cure


Once you know you're allergic to certain ingredients, do your best to avoid those allergens in the future. Food service establishments such as Burger King typically provide allergen information for their menu items online or upon request. Always check ingredient lists and make your allergies known when ordering food, to minimize the risk of subsequent allergic reactions.

Remember, every person responds differently to food allergens. It's crucial to seek professional medical advice if you suspect you have a food allergy. Be safe, not sorry.
