Spring is here and for allergy sufferers, it can be bittersweet. Spring means greening grass, budding and blooming trees and flowers – it also means the release of pollens. For individuals particularly sensitive, it can mean a season of sneezing, watery eyes and itchy noses.
With an allergic reaction, the immune system responds to a harmless substance or allergen as a foreign invader. The body then produces an antibody called immunoglobulin E (IgE), which triggers the release of three inflammatory chemicals: histamine is responsible for itchy, runny eyes and nose and sneezing; leukotrienes produce excess mucus; and prostaglandins cause inflammation.

Ragweed is the most common allergen. Other allergens include pollen, dust mites, mold, spores, pet dander, feathers and air-borne chemical pollutants. Skin testing may be required to identify the allergy.
Welcome relief
Antihistamines prevent or relieve symptoms of allergic rhinitis and other allergies by preventing histamine release. They are most effective taken a couple of weeks prior to anticipated symptoms.
Decongestants narrow blood vessels, to clear nasal congestion and other symptoms associated with colds and allergies. Decongestants’ known side effects are nervousness, sleeplessness or elevated blood pressure.
Prescription medications or allergy shots may be required for severe allergies. Shots are given yearly, prior to allergy season.
If you have allergy medication from last season check the product’s expiry date before using. If it has expired, bring it to your Rexall family pharmacist for safe disposal and he or she can help you determine which Rexall branded allergy products will give you or your family member the best relief with extra savings.
