Allergic Reaction

Home Treatment

For tips to help relieve symptoms of an allergic reaction, see home treatment for:

• A severe allergic reaction. If you have symptoms of a severe allergic reaction, call911or other emergency services immediately.
• Itching or hives. Avoid further contact with whatever you think is causing the hives.
• A sore throat caused by post-nasal drip. Gargle with warm salt water to help ease throat soreness.
• Hay fever symptoms. Take an antihistamine to reduce symptoms of itchy, watery eyes; sneezing; or a runny, itchy nose. Be sure to read and follow any warnings on the label. Check with your doctor before giving an antihistamine to a child who is younger than 1 year.
• Allergies that are worse in damp weather. Mould may be the cause of allergies that get worse in damp weather. Mould produces spores that move, like pollen, in outdoor air during warmer months. During winter months, indoor moulds 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 as well as 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.
• Seasonal allergies. These are often caused by exposure to pollen.
