Seasonal sniffles, itchy eyes, sneezing, or constant congestion — sound familiar? If you suffer from allergies, you're not alone. Millions of Canadians struggle with symptoms triggered by pollen, dust, mold, or pet dander.

What Are Allergies and Why Do They Occur?
Allergies are an overreaction of the immune system to substances that are normally harmless, such as pollen, pet dander, or dust mites. These substances are known as allergens. When exposed, your body releases histamine — the main chemical responsible for allergy symptoms. This is why antihistamines, which block histamine, are so widely used in allergy treatment. The symptoms can vary from mild sneezing and runny nose to severe breathing difficulty in some individuals.
Types of Allergies
- Seasonal Allergies (Hay Fever): Caused by pollen from trees, grasses, or weeds.
- Perennial Allergies: Triggered year-round by dust mites, mold, or pet dander.
- Food Allergies: Reactions to proteins in food such as peanuts, shellfish, or milk.
- Skin Allergies: Includes eczema, hives, or allergic contact dermatitis.
Knowing the type of allergy you’re dealing with helps identify the best allergy medicine for your condition.
Understanding Allergy Medications
There are several types of allergy medications. The most common are:
- Antihistamines: Block histamine to relieve sneezing, runny nose, and itchiness
- Decongestants: Reduce nasal swelling and pressure
- Corticosteroid nasal sprays: Reduce inflammation inside the nose
- Leukotriene receptor antagonists: Block inflammatory chemicals involved in allergic reactions
Best Over-the-Counter Antihistamines
Below are some of the best over the counter antihistamines based on symptom control, drowsiness, and patient satisfaction:
- Cetirizine (Reactine®): Great for strong seasonal allergies and indoor allergens.
- Loratadine (Claritin®): Non-drowsy and ideal for mild symptoms or daytime use.
- Fexofenadine (Allegra®): A favorite among active users — works without sedation.
- Diphenhydramine (Benadryl®): Most potent, but very sedating — best for nighttime relief.
Advanced Tips for Choosing the Right Allergy Pill
Ask yourself:
- Do you want all-day coverage?
- Do you need something non-drowsy for work or driving?
- Are your symptoms mainly nasal, skin-related, or respiratory?
Your pharmacist can help you decide what is the best daily allergy medicine depending on your answers.
