What steps can I take to avoid allergy attacks?

Medicines help treat your allergy symptoms once you have them, but there are several steps you can take to prevent symptoms before they occur. The following recommendations can help you avoid allergy attacks whether you are at home, school, work, outdoors, or out on the town.

At home

  • Keep windows closed and use air conditioning if you are allergic to pollen or outdoor molds; do not use fans, as they can stir up dust.
  • Filter the air. Cover air conditioning vents with cheesecloth to filter pollen and use a high efficiency particulate air filter (HEPA) if you have a forced air furnace. Clean air filters frequently and air ducts at least once a year.
  • Keep the humidity in your house below 50 percent to prevent mold growth or proliferation of dust mites. Avoid areas where molds may collect, including basements, garages, crawl spaces, barns, and compost heaps. Clean these areas often.
  • Install dehumidifiers in basements and other areas of the house where mold may collect; clean these devices every week. Air out damp clothes and shoes (in the house) before storing.
  • If you have pets, consider keeping them outside, or perhaps ask someone else to take care of them. Otherwise, do not allow pets in the bedroom, and consider bathing your pets often. Do not allow pets to sit on the furniture. Close air ducts in the bedrooms.
  • Remove laundry from the washing machine promptly; don't leave wet clothes in the washer.
  • Wash shower curtains and bathroom tiles with mold-killing solutions.
  • Do not collect too many indoor plants, as the soil encourages mold growth.
  • Store firewood outside.
  • If you are allergic to dust mites:
    • Use plastic covers for pillows, mattresses, and box springs.
    • Avoid overstuffed furniture and down-filled bedding or pillows.
    • Remove stuffed animals from the bed.
    • Avoid sleeping on a bottom bunk.
    • Wash your bedding every week in hot water, hotter than 130 degrees F.
  • Do not allow smoking in your house.
  • Wear a mask and gloves when cleaning, vacuuming, or painting to limit dust and chemical exposure.
  • Vacuum twice a week.
  • Limit throw rugs to reduce dust and mold. If you do have rugs, make sure they are washable.
  • When possible, choose hardwood floors instead of carpeting. If you must have carpeting, choose low pile material.
  • Avoid Venetian blinds or long drapes, as they collect dust. Replace old drapes and use window shades instead.
  • Make sure there is an exhaust fan over the stove to remove cooking fumes.


  • Keep windows closed and set the air conditioner on recirculate if you are allergic to pollen or outdoor molds.


  • Minimize walks in wooded areas or gardens.
  • Check the forecast; stay indoors as much as possible on hot, dry, windy days when pollen counts are generally the highest.
  • Try to avoid extreme temperature changes, as they are triggers for some people with asthma.
  • If possible, stay indoors between 5:00 a.m. and 10:00 a.m. when outdoor pollen counts are usually the highest.
  • Wear a mask (such as an inexpensive painter's mask) when mowing the lawn if you are allergic to grass pollen or mold; if possible, avoid mowing and being around freshly cut grass.
  • Wear a mask when gardening, as flowers and some weeds release pollen and can cause allergy symptoms.
  • Avoid raking the leaves or working with hay or mulch if you are allergic to mold.
  • After being outdoors, take a shower, wash your hair, and change your clothes to remove pollen that may have collected in your clothes and hair.
  • Dry clothes in a dryer. Do not hang clothes or linens out to dry, as pollen and molds may collect in them and make your allergies worse.


  • Pack your medications with you in your carry-on bag.
  • Bring an extra supply of medications in case you need them.

Hotel stays

  • Ask for a nonsmoking room.
  • Remove down or feather pillows and ask for synthetic, non-allergenic pillows, or bring your own pillow or plastic pillow cover from home.
  • If possible, keep the vent on the room air conditioner shut.


  • Eat in smoke-free restaurants.
  • For food allergies: avoid the foods that cause your allergy symptoms by carefully reading ingredient labels and asking about the food preparation methods when dining out. Choose fresh foods rather than prepared or processed foods. If you have severe symptoms, such as anaphylaxis, carry an epinephrine injection kit (EpiPen® or AuviQ® or Adrenaclick® ) with you at all times.

For children in school

  • Discuss your child's allergies with school personnel.
  • Inform school personnel about the medications your child is taking and make arrangements to leave necessary medications at school.
  • Encourage sports participation, but inform coaches of medications that your child may need to take in association with activity.
