Allergic rhinitis is a common condition that involves inflammation of the nasal mucous membranes, sinuses and eyes. It is triggered by an overreaction of the immune system to an otherwise harmless substance, or allergen.. This triggers a defense response from the immune system: it releases chemicals, such as histamine and leukotrienes, causing the allergy symptoms.
Most common symptoms of rhinitis are the following:
The “Common cold” is a viral infection of the upper respiratory tract – namely, the nose and the throat. Over 100 viruses can lead to the cold, but it’s commonly caused by the highly contagious rhinovirus. This virus is prevalent all year long so you can catch a cold at any time.
The symptoms of a cold are the following and can last up to 7 days:
It’s easy to confuse the symptoms of hay fever (a form of allergy) and those of the common cold, as they share many similarities.
| Hay Fever | Cold | |
|---|---|---|
| Nasal discharge (mucus secretion) | Very liquid (transparent), may sometimes thicken | Thick (white, yellowish, or greenish) |
| Nasal congestion | Both nostrils | One or both nostrils |
| Sneezing | Often (serial) | Occasionally |
| Itchiness | In the nose or throat | No itchiness |
| Red, watery, or itchy eyes | Often | No eye symptoms |
| Cough | Sometimes, especially if the person is asthmatic | Often |
Seasonal allergies: When the allergen that causes allergic rhinitis is only present at a specific time of the year, the symptoms will appear at the same time every year. For example, in the spring for people who are allergic to tree pollen or in the fall for those with a ragweed allergy.
Perennial allergies: When the allergen is present year-round in the environment, symptoms can occur all year long. Dust mites, dust and molds are examples of allergens that can cause allergic rhinitis throughout the year.
If you’re not sure what’s causing your symptoms, talk to your pharmacist. They can help determine whether you’re suffering from allergic rhinitis or a common cold, and may refer you to a doctor, if necessary. They may also suggest certain medications or other measures to relieve your symptoms.
