How to Prepare for Allergy Season 

Getting a head start provides longer periods of relief—or even no symptoms at all—rather than the “two steps forward, one step back” cycle that allergy season often feels like. Here are a few ways to prepare for allergy season before it hits.  

Know Your Triggers 

Understanding whether it’s pollen, dust, pet dander, or snow mould that sets off your allergies keeps you prepared on when to start allergy medications, which types are most effective, and how to reduce these triggers in your home environment.  

Start Treatment Early  

Allergies can build over time, making symptoms harder to manage. Starting antihistamines like Allegra and Reactine early can prevent reactions such as sneezing, congestion, itchy eyes, or fatigue from fully developing. Start taking them one to two weeks before your region’s allergy season and use them consistently to keep symptoms milder, shorter, and easier to control.  

Stock Up On Essentials 

The last thing you feel like doing when battling allergies is a quick run to the store, so keep the best tools for you and your family on hand. Antihistamines, tissue, nasal rinses, and children’s allergy formulations should all be in your allergy medicine cabinet.  

Check Your Home Environment 

Routine checks and cleaning should happen more frequently in an allergy-sensitive home. Wash bedding weekly and change furnace filters monthly. Monitor high-pollen days in your weather app and keep windows closed during peak times.   

Plan for Outdoor Exposure  

Consider rescheduling outdoor activities when pollen levels are high and begin taking antihistamines the day before. Afterwards, shower if you can, or at the very least, change your clothes to prevent allergens from remaining in contact with your skin for too long.  

When to Start Allergy Medications 

Knowing when to start allergy meds can make a huge difference in how much relief you get from your triggers—waiting until they’re in full swing greatly reduces the effectiveness of your medications. Pharmacists suggest getting ahead of the game by starting your antihistamines 1 to 2 weeks before the season begins. It’s better to be overprepared than to play catch-up with your allergies mid-season.  

When Does Allergy Season Start? 

Allergy season doesn’t start at the same time across Canada. Here’s a quick breakdown to help you identify when to expect allergies in your region.  

  • British Columbia: Early March, with tree pollen appearing first 
  • Alberta and Saskatchewan: Late March to April, depending on snow melt 
  • Manitoba: April, as temperatures rise and snow mould clears 
  • Ontario and Quebec: April to May, with tree pollen followed by grass 
  • Atlantic Canada: Late April to May, with a slightly delayed start due to the coastal climate

Take Snow Mould Allergies Into Account  

As snow melts, snow mould spores can trigger early allergy symptoms, especially in the Prairies, Ontario, and Quebec. If snow mould allergies affect you, start your allergy routine early and avoid damp outdoor areas to reduce exposure and prevent early-season flare-ups. 

 

LD Tip: Talk to a Pharmacist for Guidance  

Pharmacists at London Drugs are available for guidance on minor ailments and over-the-counter treatments. They can also help you approach your allergies holistically by assessing your symptoms, identifying patterns of when they improve or worsen, and offering lifestyle recommendations that you may not have considered.

Preparedness is prevention, especially when it comes to seasonal allergies. Make sure your home is stocked with essentials from each of these categories, and you’ll be ready for whatever comes your way this season.  

Allergy Medications 

Oral antihistamines are a must-have. Products like Allegra and Aerius are designed for daily use to keep symptoms under control and interrupt the allergy response cycle. Others, like Benadryl and Reactine, can be used as boosters for breakthrough symptoms and provide fast-acting relief at the onset of irritation. Shop allergy medications at London Drugs for the best allergy products in Canada.  

Children’s Allergy Relief 

While adult and children’s allergy medications can contain the same active ingredients, it’s important not to guess on the correct dose and delivery system. Keep children’s allergy relief on hand, and make a note of the differences between infant and general children’s formulations. Talk to a pharmacist if you’re unsure which allergy meds are best for your child.  

Eye Drops 

Eye drops for allergies from brands like Bausch & Lomb can help relieve dryness and flush out irritants, while antihistamine drops from brands like Alcon can target itchiness and redness for fast relief. 

Nasal Sprays and Rinses 

Sinus products, such as nasal sprays and rinses, are formulated to help with allergy-related stuffiness and dryness. Nasal sprays can provide highly effective relief from congestion, but read the manufacturer’s instructions and use them carefully. Overuse can lead to rebound congestion, causing prolonged stuffiness even after any irritants subside. Nasal rinses, on the other hand, are safe to use as needed and can prevent additional irritations caused by repeated nose-blowing. Ask a pharmacist for help deciding which type is best for your needs.  

Air & Home 

Air purifiers are among the most effective tools for controlling indoor allergens. Place them in common areas and bedrooms, leaving enough space around them to allow proper air circulation. Brands like Honeywell and Winix last for years with regular filter changes, helping keep your home environment a safe zone for you and your family.  

Cleaning Supplies 

The last line of defense against allergens in your home is maintaining a clean environment. Stock up on cleaning essentials, such as gentle, low-irritant products, and supplies to remove dust and allergens from carpets and surfaces.

Let’s talk allergies

What is an allergy exactly?

It’s a reaction that occurs when our immune system overreacts to something that isn’t usually harmful and causes unpleasant symptoms. There are different types of allergies, including food allergies, allergies to certain medicines, and allergies that affect the nasal passages and eyes. According to the Canadian Allergy, Asthma, and Immunology Foundation, about 20% to 25% of the Canadian population has allergic rhinitis (also known as hay fever). Allergies can happen any time of the year, but airborne allergies are most common in the spring and summer when we spend more time outdoors, and there are more allergy triggers floating in the air for us to breathe in.

Rhinitis is an inflammation (swelling) of the lining of the nose. Not all rhinitis is caused by allergies, but someone with allergic rhinitis could be reacting to exposure to allergens (substances that trigger allergy symptoms) such as grass or tree pollen, ragweed, animal dander, dust mites, or mould spores. Common symptoms include an itchy nose and throat, runny or stuffy nose, sneezing, ear blockage, and sometimes watery, red, itchy eyes.

A Holistic Approach

The best way to prevent and treat airborne allergies like pollen or mould is to develop a holistic plan that includes both medications and lifestyle modifications. Don’t wait until you have symptoms to start making your plan. Start by having a consultation with your London Drugs pharmacist, who can work with you to create a plan that will help you manage your allergies and enable you to enjoy being outdoors.

Step one of your plan should be to try to identify the substances that trigger your allergy symptoms. If you cannot figure out what is causing your symptoms or if your symptoms are severe, your doctor can refer you to an allergy specialist for testing.

Step two is to determine which treatments would work best for you.  Your pharmacist can help you understand what medications are available, how they work, and how to use them to get the best results.

Allergy Prevention

If your allergy is to pollen, try to limit your time outdoors when pollen counts are highest, usually between 7 a.m. and 1 p.m., and on dry, windy days. When you go inside after being outdoors, shower and change your clothes immediately to wash off the pollen that might be sticking to your skin, your hair, or your clothes. After laundering your clothes, do not hang them on an outdoor line to dry, because this will allow pollen to cling to the fabric.

Clean your home frequently and do not leave windows and doors open, as this allows pollen and other allergens to enter your home, where they can collect on carpets and furniture, exposing you to them for longer periods. Use an air conditioner and be sure to change the filter regularly and maintain it properly.

If you are allergic to indoor moulds or mildew, regularly clean surfaces where moisture collects, such as window frames, bathrooms, and bedroom corners, and keep your home’s humidity below 50%. A dehumidifier can help control moisture, limit mould and mildew growth, and reduce allergy symptoms.

Symptom Treatment

Sometimes, preventative measures are not enough to eliminate allergy symptoms. Fortunately, there are a number of medications that treat allergies in different ways. Your healthcare team can recommend products that would be best for you, but the chart below can serve as a general guide on what is available.

Antihistamines – Antihistamines block certain cells in the body from receiving histamine, a chemical released by the immune system that causes the symptoms of an allergic reaction.

Corticosteroids – Corticosteroid sprays, also called glucocorticoid or steroid sprays, reduce inflammation in the nasal passages to ease allergy symptoms.  When used regularly, they relieve nasal congestion and sneezing.

Leukotriene modifiers (tablets, granules) – Leukotriene modifier medications work by blocking leukotrienes – chemicals in the body that contribute to inflammation, airway narrowing, and mucus production.

Immunotherapy (tablets, injections) – Immunotherapy sublingual tablets (placed under the tongue) and allergy shots help train the immune system to become less reactive to allergens. Each dose contains a tiny amount of an allergen or mix of allergens — enough to train the immune system to recognize it, but not enough to trigger symptoms. As the dose gradually increases, the immune system becomes less reactive, and allergy symptoms improve over time.

 

Other ways you can help ease your discomfort from allergies include:

  • Saline nasal rinses – Using salt-water nasal spray or sinus rinse (such as a neti pot, rinse bottle, or nasal irrigation device) can help clear congestion and wash allergens out of your nasal passages.
  • Artificial tears or eye wash solutions – These can soothe dry, irritated eyes and help rinse out allergens.
  • Cool compress for the eyes – A clean, damp, cool washcloth placed over your eyes can reduce inflammation and itching.
  • Warm compress for the eyelids – A clean, damp, warm washcloth can help remove pollen from the eyelids and help soothe irritation.

LD Tip

Limiting the use of non-prescription eye drops for redness-relief is important. These products are meant for cosmetic use only, and some can cause rebound redness, where the eyes look even redder once you stop using them. Speak to a pharmacist for safer, long-term options to treat the underlying cause of your redness.

 

If you have any questions about seasonal allergies, allergic rhinitis, or allergic conjunctivitis (red eyes), your London Drugs pharmacists have the knowledge and experience to answer your questions and help you relieve the unpleasant symptoms. Many pharmacists can also prescribe medications to treat allergy symptoms. Ask at the pharmacy counter or visit londondrugs.com/prescribing for more information.

Don’t Suffer From Your Seasonal Allergies

As the weather warms, Mother Nature unleashes a storm of airborne allergens that cause teary eyes and stuffy noses in people who suffer from seasonal allergies, and there are a lot of us who do. In fact, nearly one-quarter of Canadians experience seasonal allergies. Specific allergy inducers vary from region to region and season to season, but tree and weed pollens are among the major offenders. Although not all of them are connected to a particular season, the ten most common allergy triggers across Canada are:

• air pollution
• dust mites (which thrive in humid weather)
• grasses
• insect bites
• mildew
• mould
• pets
• ragweed
• trees
• weeds

When pollen or other triggers are released into the air, we can inhale them, and they can travel into our nasal passages. When we are allergic to a substance we’ve breathed in, our immune system identifies it as an invader and sends out a chemical called histamine to attack it. Our reaction to the histamine is one of the causes of allergy symptoms.

We can begin to develop allergy symptoms at any time of life – in childhood, during our teen years, or even in adulthood. These symptom may include:

• Eyes that are puffy, red or watery
• Itchy eyes, nose or ears
• Runny or stuffy nose
• Frequent sneezing
• Dark circles under the eyes

Some people describe seasonal allergies as feeling like you have a bad cold that never goes away.

Treating Seasonal Allergies

It can be very difficult to eliminate the symptoms of seasonal allergies, but there are steps you can take to manage them. There are both prescription and over-the-counter medicines that can ease the symptoms. Examples include:

• Antihistamines are available as oral medicines, nasal sprays, and eye drops that help relieve sneezing, itching, runny nose, and watery eyes.

• Decongestants can provide temporary relief from nasal stuffiness and are available in oral dosage forms, nasal sprays, and eye drops.

• Combination products contain both an antihistamine and a decongestant to provide broader relief of symptoms.

• Cromolyn sodium, which can also ease symptoms, comes in various dosage forms, including nasal spray and eye drops.

• Nasal corticosteroids, a type of nasal spray, reduce inflammation in the nose and block allergic reactions.

• Leukotriene receptor antagonists block the action of chemicals other than histamine that play a role in allergic reactions. These must be taken every day to prevent symptoms before they occur.

• Allergy shots are injections given over a period of time to reduce, or sometimes even eliminate, allergy attacks. Each injection contains a tiny amount of a particular allergen that triggers your allergic reaction. The shot contains just enough of the allergen to stimulate your immune system, but not enough to cause a full reaction. Over time, the amount of the allergen in the shot is increased, and this helps your body get used to the allergen, making you less sensitive to it and less likely to have a reaction to it.

• Allergen tablets are now available. You can take them to increase your tolerance to grass and ragweed pollens. They are taken for about 12 weeks before grass pollen season starts and continued throughout the season.

• Nasal irrigation: In addition to these medications, some people find relief from saline nasal irrigation, which can relive nasal congestion by flushing mucus and allergens from the nose.

Reducing your exposure to allergens can also make it easier to get through allergy season. Here are some helpful tips:

• Avoid outdoor activity early in the morning when pollen counts are at their highest.

• Close doors and windows at night and at any other time when the pollen count is high.

• Don’t hang laundry outside to dry; pollen can stick to sheets and towels.

• When you come in from being outdoors, remove your clothes and shower to rinse the pollen from your skin and hair.

• Use the air conditioner in your home and car rather than opening the windows.

• Try wearing a mask if you must do chores outside.
