how can you prevent anaphylaxis?

Anaphylaxis is best prevented by avoiding any of the allergens that trigger your symptoms.

Avoiding food triggers

Currently, there is no medicine you can take to prevent food allergies. The only way to prevent a reaction is to strictly avoid the allergy-causing food.6

  • Grocery shopping: Always check food labels for ingredients. Manufacturers often change their product ingredients, so read the ingredient label every time you purchase a food, even a familiar food.6
  • Restaurants: Be very careful about finding out what the ingredients are and how your food is prepared. You can ask the waiter about the ingredients used in a meal before you order it. You can also speak to the restaurant manager about the menu, so that the kitchen staff will be informed about your food allergy.6
  • Traveling on a commercial airline: Read the airline’s allergy policy, which can be found posted on their website. Try to choose an airline that does not serve snacks such as peanuts, tree nuts, or anything you are allergic to. Keep in mind that it is likely no airline will be able to guarantee you a peanut-free or tree-nut-free flight.6
    • Notify the airline of your food allergy when you book your flight.6
    • Keep your epinephrine auto-injector in its original packaging.6
    • It is a good idea to have a prescription for your epinephrine auto-injector, along with a letter from your doctor stating your food allergy and indicating you need to carry your medication and your food and drink items with you.6
    • It is also a good idea to avoid eating airline food. Check with the airline to see about packing your own food.6
    • Consider getting a "medical alert" identification for yourself or family member in case you are not there when a reaction occurs.6

Avoiding environmental triggers

Insect bites and stings: The first line of defense is to avoid occasions where you may be exposed to insects that could cause an allergic reaction.7 Keep in mind that insects may build their nests in the ground, in trees or shrubs, under the eaves of houses or barns.5

  • Avoid walking barefoot in the grass.7
  • Limit mowing the lawn or gardening.5
  • Avoid drinking from open soft drink cans, where stinging insects can crawl inside.7
  • Keep food covered when eating outdoors.7
  • Avoid perfumes, hairsprays and deodorants that have a sweet fragrance.7
  • Avoid wearing brightly colored clothing with flowery patterns.7

Medicines: Anyone can get an allergic drug reaction to any drug.8 If you do have a drug allergy, here are some tips:

  • Make sure all your doctors know the specific drug you took and the drug reactions you had.8
  • Check with your doctor about related drugs that you must avoid.8
  • Check with your doctor about the drugs you can take, if needed.8
  • Wear an emergency medical alert bracelet or necklace with the name of the drug engraved.8

Latex: Here is a general list of some of the most common latex products you should try to avoid if you have an allergy to latex:

  • Latex gloves9
  • Balloons9
  • Adhesive bandages9
  • Therapy/resistance bands9
  • Pacifiers and baby bottle nipples9
  • Rubber bands, elastics, and orthodontic elastics9
  • Blood pressure cuffs9
  • Dishwashing gloves9
  • Erasers9
  • Spandex9
  • Latex mattresses9
  • Barrier contraceptive devices
