Allergic Reaction - Home Treatment

You can use home treatment to relieve symptoms of:

  • Itching or hives. Avoid more contact with whatever you think is causing the hives.
  • A sore throat caused by postnasal drip camera.gif. People age 8 years or older can gargle with warm salt water at least once each hour to help ease throat soreness.
  • Hay fever or other seasonal allergies. Use saline drops or a humidifier to help clear a stuffy nose. Or take an allergy medicine that's specific to your symptoms. Be safe with medicines. Read and follow all instructions on the label slideshow.gif.
  • Allergies that are worse in damp weather. Mold may be the cause of allergies that get worse in damp weather. Mold produces spores that move, like pollen, in outdoor air during warmer months. During winter months, indoor molds can also be a problem.
  • Indoor allergies. Newer, energy-saving homes that are built with double- or triple-paned windows and more insulation keep heat and allergens indoors.
  • Allergies to a pet or other animal. When allergies are worse around pets, symptoms may be caused by your pet's dead skin (dander), urine, dried saliva, or hair.
