Seasonal Allergies: Care Instructions

Your Care Instructions

Allergies occur when your body's defence system (immune system) overreacts to certain substances. The immune system treats a harmless substance as if it were a harmful germ or virus. Many things can cause this to happen. Examples include pollens, medicine, food, dust, animal dander, and mould.

Your allergies are seasonal if you have symptoms just at certain times of the year. In that case, you are probably allergic to pollens from certain trees, grasses, or weeds.

Allergies can be mild or severe. Over-the-counter allergy medicine may help with some symptoms. Read and follow all instructions on the label.

Managing your allergies is an important part of staying healthy. Your doctor may suggest that you have tests to help find the cause of your allergies. When you know what things trigger your symptoms, you can avoid them. This can prevent allergy symptoms and other health problems.

In some cases, immunotherapy might help. For this treatment, you get shots or use pills that have a small amount of certain allergens in them. Your body "gets used to" the allergen, so you react less to it over time. This kind of treatment may help prevent or reduce some allergy symptoms.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Take your medicines exactly as prescribed. Call your doctor or nurse advice line if you think you are having a problem with your medicine.
  • During your allergy season, keep windows closed. If you need to use air-conditioning, change or clean all filters every month. Take a shower and change your clothes after you have been outside.
  • Stay inside when pollen counts are high. Vacuum once or twice a week. Use a vacuum cleaner with a HEPA filter or a double-thickness filter.

When should you call for help?

Give an epinephrine shot if:

  • You think you are having a severe allergic reaction.

After giving an epinephrine shot, call 911, even if you feel better.

    • Sudden raised, red areas (hives) all over your body.
    • Swelling of the throat, mouth, lips, or tongue.
    • Trouble breathing.
    • Passing out (losing consciousness). Or you may feel very light-headed or suddenly feel weak, confused, or restless.
  • You have been given an epinephrine shot, even if you feel better.

Call your doctor or nurse advice line now or seek immediate medical care if:

  • You have symptoms of an allergic reaction, such as:
    • A rash or hives (raised, red areas on the skin).
    • Itching.
    • Swelling.
