A stuffy nose in the middle of spring, endless sneezing, and itchy eyes for three weeks. Is it a lingering cold or seasonal allergies? Confusion between the two is common, and it's not trivial: the treatment for a viral cold and allergic rhinitis are different, and using the wrong one for weeks unnecessarily delays relief.<\/p>\r\n\r\n\r\n\r\n
Seasonal allergic rhinitis is an immune system reaction to airborne pollens. It cannot be cured, but it can be managed very well with the right tools.<\/p>\r\n\r\n\r\n\r\n
Several clues can help distinguish between them. A cold is caused by a virus and generally lasts seven to ten days. Symptoms appear gradually, often starting with a sore throat, followed by congestion and a runny nose. A mild fever and muscle aches are possible with a cold but absent in allergic rhinitis.<\/p>\r\n\r\n\r\n\r\n
Allergic rhinitis, on the other hand, appears quickly after exposure to allergens and can last for weeks, until the pollen season ends. Sneezing is often more frequent and intense. Nasal discharge is typically clear and watery, and nasal, eye, and palate itching are characteristic. There is no fever.<\/p>\r\n\r\n\r\n\r\n
During a first exposure to an allergen, such as birch pollen, the immune system produces specific IgE antibodies without causing symptoms. This is sensitization. During subsequent exposures, these IgE antibodies trigger the release of histamine and other inflammatory mediators by mast cells in the nasal and conjunctival lining. It is this release of histamine that causes all the characteristic allergy symptoms.<\/p>\r\n\r\n\r\n\r\n
The reaction can occur within minutes of exposure and persist as long as the allergen is present. Some people also develop a late-phase reaction a few hours later, which contributes to chronic nasal congestion during the season.<\/p>\r\n\r\n\r\n\r\n
Reducing pollen exposure is complementary to drug treatment. Monitoring pollen counts, available on several Quebec weather websites, helps anticipate high-risk days. Pollen concentrations are generally higher in the morning during dry, windy weather and lower after rain.<\/p>\r\n\r\n\r\n\r\n
Keeping windows closed during peak pollen hours, using air conditioning instead of natural ventilation in the car, changing and showering after long periods outdoors, and avoiding hanging laundry outside during pollen peaks are practical measures that reduce the daily allergenic load.<\/p>\r\n\r\n\r\n\r\n
Nasal corticosteroids, prescribed by a doctor, are the most effective treatment for moderate to severe allergic rhinitis. They reduce all nasal symptoms, and their effect increases with regular use. Oral antihistamines relieve nasal and eye symptoms but are less effective for congestion. Nasal decongestant sprays containing xylometazoline offer rapid relief from congestion but should not be used for more than five to seven consecutive days to avoid a rebound effect.<\/p>\r\n\r\n\r\n\r\n
Can allergic rhinitis have complications?<\/strong> Are there tests to identify the responsible allergens?<\/strong> Does allergic rhinitis disappear with age?<\/strong> If you are not sure whether your symptoms are allergy-related, if your seasonal rhinitis affects your sleep or daily activities, or if antihistamines are no longer sufficient, you should consult a doctor.<\/p>\r\n\r\n\r\n\r\n A doctor or a specialized nurse practitioner can assess your symptoms, prescribe appropriate treatment, and refer you to an allergist if necessary. An in-person or teleconsultation<\/a> at one of our Omicron Clinic<\/a> in Quebec gives you quick access.<\/p>\r\n
Yes. Untreated or poorly controlled allergic rhinitis can lead to recurrent sinusitis, serous otitis media, and worsen asthma if present. Nasal polyposis is a possible complication in severe and chronic cases.<\/p>\r\n\r\n\r\n\r\n
Yes. Allergy skin tests, performed by an allergist, help identify the specific allergens that trigger symptoms. This information guides the choice of targeted immunotherapy if this option is considered.<\/p>\r\n\r\n\r\n\r\n
For some people, symptoms improve over time. For others, they persist or worsen. Immunotherapy is the only option that can induce long-lasting tolerance to allergens.<\/p>\r\n\r\n\r\n\r\nWhen to consult a healthcare professional<\/h3>\r\n\r\n\r\n\r\n
