Sore Throat and Allergies

A sore throat, also known as pharyngitis, is a common medical condition characterized by pain, discomfort, or scratchiness in the throat. It typically arises when the throat's mucous membranes become inflamed or irritated due to various causes, such as viral or bacterial infections, allergens, environmental factors, or excessive throat strain. Sore throats can vary in severity, from mild irritation to severe pain, and may be accompanied by other symptoms like difficulty swallowing, coughing, or a hoarse voice. While viral infections like the common cold are among the most common causes of sore throats, bacterial infections like strep throat can also lead to more severe and persistent symptoms. Sore throats are a widespread ailment, and their treatment and management often depend on the underlying cause, making it important to identify the cause for appropriate treatment and management. 

Allergies with a sore throat

Sore throats are a common symptom of allergies due to the body's immune response to allergens. When an individual with allergies comes into contact with allergens like pollen, dust mites, pet dander, or certain foods, their immune system can overreact and release histamines. Histamines are chemicals that cause inflammation and irritation in various parts of the body, including the throat. This inflammation can lead to a sore or scratchy throat. Additionally, postnasal drip, a common allergy symptom, can further exacerbate throat discomfort as mucus from the nose drips down the back of the throat, causing irritation. Therefore, it's not uncommon for people with allergies to experience sore throats as a direct result of their immune system's response to allergens, making it one of the hallmark symptoms of allergic reactions.

What does an allergy sore throat feel like?

An allergy sore throat can be a rather uncomfortable and irritating experience. It typically feels like a persistent, scratchy, and sometimes itchy sensation at the back of the throat. This discomfort is often accompanied by a frequent urge to clear the throat or cough. The reason behind this sensation lies in the body's immune response to allergens. When allergens, such as pollen, dust, or certain foods, are encountered by a person with allergies, the immune system perceives them as threats and releases histamines, which can lead to inflammation and irritation in the throat. This inflammation, in turn, results in the characteristic soreness and discomfort of an allergy-related sore throat. It's important to note that an allergy sore throat is typically not associated with fever or other symptoms commonly seen in viral or bacterial infections, helping to differentiate it from other causes of sore throats.

How long does a sore throat from allergies last?

The duration of a sore throat caused by allergies can vary from person to person and largely depends on the individual's sensitivity to allergens, the specific allergen involved, and their overall health. Allergy-related sore throats can persist for as long as the allergen exposure continues. For instance, during a high pollen season, the sore throat may persist for several days or even weeks if the person is constantly exposed to pollen. However, once the allergen is removed or the allergy is managed effectively with antihistamines or other allergy medications, the sore throat should gradually improve.

If a sore throat persists for an extended period and is not associated with allergies, it could be due to other underlying conditions. A short-lived sore throat (lasting a few days) is often attributed to viral infections like the common cold or influenza. In contrast, a prolonged sore throat (lasting more than a week) may be indicative of a bacterial infection, such as strep throat, which often requires antibiotics for treatment. Other potential causes of persistent sore throats may include postnasal drip, gastroesophageal reflux disease (GERD), or environmental factors like smoking or dry air. It's crucial to consult a healthcare professional if a sore throat persists or is accompanied by severe symptoms to determine the underlying cause and receive appropriate treatment.

How bad is a sore throat from allergies?

A sore throat from allergies can vary in severity, ranging from mild discomfort to more pronounced irritation. In more severe instances or when allergies are left untreated, the sore throat can worsen. Prolonged exposure to allergens can lead to persistent inflammation and a more intense sore throat. It might become painful, making swallowing and talking uncomfortable. Additionally, severe allergy symptoms can trigger secondary complications like sinusitis or bronchitis, which can further exacerbate throat discomfort. It's essential to address allergies promptly through allergen avoidance measures or medications, as untreated or severe allergies can lead to more significant throat-related issues and a decreased quality of life.

Can seasonal allergies cause a sore throat?

Seasonal allergies, also known as hay fever or allergic rhinitis, can indeed cause sore throats, and different allergens trigger these reactions during specific seasons. Here's an overview of common seasonal allergies, their allergy seasons, and the severity of their impact:

Mold Spores:

Mold spores can be present year-round but are more prevalent in warm, damp conditions, making them common in late summer and early fall. Mold spore allergies can range from mild to severe, with symptoms exacerbated in high humidity.


Ragweed allergies typically peak in late summer and early fall. Ragweed pollen is a potent allergen and can cause significant allergic reactions, including sore throats.

Grass Pollen:

Grass pollen allergies are most prevalent in late spring and early summer. Grass pollen can be a moderate-to-severe allergen, leading to various allergy symptoms, including sore throats.

Tree Pollen:

Tree pollen allergies are common in the spring. The severity of tree pollen allergies can vary depending on the specific type of tree, but they are generally moderate in nature.

Other Weeds (e.g., Sagebrush, Lamb's Quarters):

Allergies to other weed pollen types can occur in late summer and early fall. The severity varies, with some weed pollen allergens causing more severe symptoms than others.

It's important to note that individual reactions to these allergens can differ, and the severity of symptoms can vary. People with allergies may experience a range of symptoms, including a sore throat, runny or stuffy nose, sneezing, and itchy or watery eyes.

How do you get rid of an allergy sore throat?

Short-term treatments

  • Over-the-Counter Medications: Consider using antihistamines, decongestants, or combination allergy medications to reduce inflammation and block histamine release.
  • Salt Water Gargle: Soothe a sore throat temporarily by gargling with warm salt water.
  • Allergen Avoidance: Stay indoors on high pollen days, use air purifiers, keep windows closed, and maintain a clean living environment to reduce allergen exposure.
  • Nasal Irrigation: Use saline solutions for nasal irrigation to rinse allergens from nasal passages, reducing postnasal drip and throat irritation.
  • Hydration: Stay well-hydrated by drinking plenty of fluids to keep the throat moist and ease discomfort.
  • Humidifier Use: Consider using a humidifier in your bedroom to add moisture to the air, reducing throat dryness.

Long-term treatments

At Aspire Allergy & Sinus, we offer a range of long-term treatments to address allergy-related sore throat symptoms effectively:

Allergy Shots (Immunotherapy):

Allergy shots, also known as immunotherapy, involve administering gradually increasing doses of allergens to help the body build tolerance over time. This reduces the body's exaggerated immune response to allergens. Immunotherapy can significantly alleviate sore throat symptoms by desensitizing the immune system to the specific allergens responsible for the discomfort. This long-term treatment aims to reduce the frequency and severity of sore throats caused by allergies.

Allergy Drops (Sublingual Immunotherapy):

Sublingual immunotherapy, also known as allergy drops, involves placing liquid drops containing allergen extracts under the tongue, where they are absorbed. Over time, the body becomes less reactive to these allergens. Like allergy shots, sublingual immunotherapy helps reduce the immune response to allergens. By addressing the underlying allergic triggers, it can provide long-term relief from sore throat symptoms caused by allergies.

ExACT Immunoplasty:

ExACT Immunoplasty combines the power of immunotherapy with advanced diagnostics to pinpoint specific environmental allergens affecting the patient. It offers personalized treatment plans. By precisely identifying and targeting the specific allergens responsible for sore throat symptoms, ExACT provides tailored and effective long-term relief. This approach aims to eliminate or greatly reduce sore throat discomfort related to allergies.

These long-term treatments at Aspire Allergy & Sinus are designed to address the root causes of allergy-related sore throats, offering patients sustained relief and an improved quality of life by gradually desensitizing the immune system to allergens and reducing the frequency and severity of allergic reactions.

How do I know if my sore throat is due to allergies?

Here are some things to look out for to help determine if your sore throat is due to allergies:

Seasonal Patterns: Pay attention to the timing of your sore throat symptoms. Allergies often exhibit seasonal patterns, with symptoms peaking during specific times of the year when allergens like pollen, grass, or ragweed are prevalent.

Accompanying Symptoms: Take note of any additional allergy symptoms you may be experiencing. Allergies commonly cause symptoms like sneezing, itchy or watery eyes, nasal congestion, and a persistent cough in addition to a sore throat.

Triggers: Identify potential allergens that could be triggering your sore throat. Common allergens include pollen, dust mites, pet dander, and specific foods. If exposure to these allergens coincides with your sore throat episodes, it may be an indication of allergy involvement.

Consistency: Consider the consistency of your symptoms. Allergies often lead to chronic or recurrent sore throats, especially when exposed to allergens regularly. If your sore throat persists over an extended period or occurs seasonally, allergies could be a likely culprit.

Consult an Allergist: For a definitive diagnosis, it's advisable to consult with an allergist. Allergists can perform tests such as skin prick tests or blood tests to determine the specific allergens causing your symptoms. These tests can confirm whether your sore throat is indeed related to allergies or if another underlying condition is involved.

If you suspect that allergies may be contributing to your sore throat, seeking the expertise of an allergist can help you identify the triggers and develop an effective management plan to alleviate your symptoms and improve your overall quality of life.

FAQ's about sore throat and allergies

What is the best allergy medicine for a sore throat?

The best allergy medicine for a sore throat is one that treats the underlying causes of your allergies, not just masks the symptoms. Those would be long-term treatments such as allergy shots, allergy drops, or ExACT Immunoplasty. However, if you’re looking for something quick and effective, you can try soothing your throat by drinking hot tea or taking over-the-counter antihistamines. Medications such as loratadine (Claritin), cetirizine (Zyrtec), or fexofenadine (Allegra), can be effective in relieving throat discomfort related to allergies by reducing inflammation and histamine response. For individuals with persistent or more severe allergy symptoms, combination allergy medications that include an antihistamine and a decongestant, like loratadine-pseudoephedrine (Claritin-D) or cetirizine-pseudoephedrine (Zyrtec-D), may provide added relief. 

Can allergies cause a sore throat?

Yes, allergies can cause a sore throat. When allergens like pollen, dust mites, or certain foods are encountered, the immune system can react by releasing histamines, leading to throat irritation and discomfort. Postnasal drip, a common allergy symptom, can further contribute to a sore throat.

What if my sore throat isn’t from allergies?

Sore throat symptoms that are not allergy-related often indicate an underlying infection, commonly caused by viruses or bacteria. In these cases, individuals may experience a painful and scratchy sensation in the throat, which can make swallowing uncomfortable. The throat typically appears red and inflamed, and coughing may be present. 

Bacterial infections, such as strep throat, can lead to more severe symptoms like a high fever, headache, and swollen lymph nodes in the neck. Viral infections, like the common cold or flu, may also be accompanied by symptoms such as a runny or stuffy nose, sneezing, and body aches. It's essential to differentiate between allergy-related and infection-related sore throats, as the treatment approaches can vary significantly, with bacterial infections often requiring antibiotics for resolution.

What if I have a sore throat but I’m not sick?

If you have a sore throat but are not experiencing other symptoms typically associated with an illness, such as a fever, cough, or congestion, it's possible that your sore throat may be due to non-infectious factors.
