Allergy Symptoms: Can Allergies Cause a Sore Throat?

19 Dec 2023

Allergies are a chronic medical condition that occurs when the immune system reacts excessively to substances that are usually harmless. These substances, called allergens, trigger an immune response in individuals with allergies. Common allergens include pollen, dust mites, mold spores, pet dander, insect stings, certain foods, and medications.

When a person with allergies comes into contact with an allergen, their immune system produces specific antibodies called immunoglobulin E – or - (IgE) antibodies. These IgE antibodies then trigger the release of chemicals, including histamine, to try and protect the body from what it perceives as a threat. It's the release of these chemicals that leads to allergy symptoms.

A Sore Throat & Other Common Allergy Symptoms

Allergy symptoms can vary widely depending on the type of allergen and the individual's sensitivity. Common allergic reactions include:

  • Sore Throat: Nasal congestion and post nasal drip can cause a sore throat.
  • Sneezing: Sneezing is a common symptom, especially in response to allergens like pollen and dust.
  • Stuffy or Runny Nose: Allergies often cause nasal congestion, runny nose, and postnasal drip.
  • Itchy or Watery Eyes: Red, itchy, and watery eyes are common allergic symptoms, particularly during exposure to pollen or pet dander
  • Coughing and Wheezing: Allergies can lead to coughing and wheezing, especially in individuals with allergic asthma.
  • Skin Reactions: Skin allergies can result in hives (raised, itchy welts) or eczema (itchy, inflamed skin).
  • Body Aches: This is not a common allergic response, however, allergens can lead to inflammation and manifest as body aches and pains.

It's important to note that not everyone is allergic to the same substances, and the severity of allergic reactions can vary. Allergies can develop at any age, and they tend to run in families. Some people may outgrow allergies over time, while others may develop new allergies.

Allergy management typically involves avoiding known allergens, taking medications like antihistamines or decongestants to alleviate symptoms, and in some cases, undergoing allergy shots (immunotherapy) to build tolerance to specific allergens.

What are Some Common Seasonal Allergens?

Common seasonal allergens vary depending on the time of year and location, but here are some of the most prevalent ones for each season in many regions:


Pollen Allergy: Tree pollen is a significant allergen in the spring. Common trees that release allergenic pollen include oak, birch, cedar, maple, and pine.

Grass Pollen: Some grasses, such as Timothy grass, Kentucky bluegrass, and Bermuda grass, release allergenic pollen in the spring.

Mold Spores: As the weather warms up and becomes more humid, mold spore counts can rise, causing allergic reactions.


Grass Pollen: Grass pollen allergies tend to peak in late spring and early summer.

Weed Pollen: Certain weeds, like ragweed, release pollen during the summer months, causing allergic symptoms.


Weed Pollen: Ragweed is a dominant allergen in the fall, and its pollen can be a major trigger for allergies.

Mold Spores: Mold spore levels can remain elevated into the fall season, especially in damp or rainy conditions.


Indoor Allergens: While outdoor allergens decrease in the colder season of the year, indoor winter allergies become more prominent. Common indoor allergens include dust mites, pet dander, cockroach droppings, and indoor mold in areas with poor ventilation.

Specific allergens and their prevalence vary by region and climate. Some people may be allergic to year-round allergens like dust mites or pet dander, which can cause symptoms throughout the year.

How Do I Know if My Sore Throat is from Allergies?

How Do I Know if My Sore Throat is from Allergies


Differentiating between sore throats caused by allergies and one caused by other factors can be challenging because both can share similar symptoms. Here are some clues that may help you determine if your sore throat is due to allergies:

Seasonal Patterns: Allergies, such as pollen allergies (hay fever or allergic rhinitis), often follow seasonal patterns. If your sore throat tends to occur during specific times of the year when certain allergens are prevalent, like spring or fall, it might be related to allergies.

Accompanying Symptoms: Allergies typically come with other symptoms like sneezing, runny or stuffy nose, itchy or watery eyes, and sometimes coughing. If you have these symptoms along with a sore throat, it's more likely to be allergy-related.

Environmental Triggers: Consider if you were recently exposed to potential allergens, such as pollen, pet dander, dust mites or mold. If you were in an environment where these allergens are present, it could contribute to your sore throat.

No Fever: Allergies don’t typically cause a fever. If you have a sore throat without an elevated body temperature, it's less likely to be caused by an infection.

Consistent Symptoms: Allergies tend to cause consistent symptoms when you're exposed to allergens. If you notice that your sore throats occur in specific situations or locations where you encounter allergens, it might be related to allergies.

Response to Allergy Medication: Taking over-the-counter allergy medications, such as antihistamines or nasal sprays, can often provide relief from allergy-related symptoms, including a sore throat. If your sore throat improves after taking these medications, it suggests an allergic cause.

History of Allergies: If you have a known history of allergies, especially if you've been diagnosed by an allergist, and you experience a sore throat along with other symptoms as an allergic response, it's more likely to be related to allergies.

Is it Normal to Get a Sore Throat from Allergies?

Yes, it is normal to get a sore throat from allergies, especially if you have allergic rhinitis (hay fever). Allergies can cause a range of symptoms, including sneezing, runny or stuffy nose, itchy or watery eyes, a sore throat, and even an allergy cough.

When you are exposed to allergens that you are sensitive to such as pollen, pet dander, dust mites or mold spores, your immune system reacts to them.

Your immune system releases histamines and other chemicals in response to the allergens. These chemicals can cause inflammation and irritation in various parts of your body, including your throat.

Allergies often lead to postnasal drip, where excess mucus produced in your nose and throat drips down the back of your throat. This can irritate the throat lining and lead to a sore or scratchy throat.

Postnasal drip can also trigger coughing, which can further irritate your throat and nasal passages.

How Long Will Allergy Sore Throats Last?

The duration of an allergy-related sore throat can vary from person to person and depends on several factors, including the individual's sensitivity to allergens, the specific allergens involved, and the effectiveness of allergy management. Here are some general guidelines:

Acute Sore Throat: An allergy-related sore throat is typically acute. It can persist for a few days to a couple of weeks, especially if you continue to be exposed to allergens.

Seasonal Allergy Symptoms: If your sore throat is primarily triggered by seasonal allergens like pollen, it may coincide with specific times of the year when these allergens are prevalent. In such cases, your sore throat is likely to improve as the allergen levels decrease.

Chronic Allergies: Some individuals have chronic allergies, such as year-round allergies to dust mites, pet dander or mold. In these cases, a sore throat can be persistent if allergen exposure remains constant.

Relieving Sore Throat Symptoms from Allergies

The severity of an allergy-related sore throat or even one that is due to cold symptoms can be improved with appropriate treatment. Over-the-counter medications such as InstaSoothe Sore Throat + Pain Relief Spray in Cherry Flavor that numbs pain fast with two powerful pain relieving active ingredients or InstaSoothe Sore Throat + Soothing Comfort Honey and Echinacea Flavor lozenges that are fast-acting and soothe throat pain are both effective options for temporary relief of throat pain symptoms.

If you find that your sore throat persists or worsens despite your efforts to manage your allergies or if you experience other concerning symptoms, consult a healthcare professional for a thorough evaluation and personalized treatment.

Chronic or recurrent throat symptoms should not be ignored, as they can sometimes be a sign of other underlying conditions that require medical attention. Mucinex® products are formulated to help ease your sore throat and other cold and allergy symptoms to help you get back to feeling better fast.
