Can Allergies Cause a Sore Throat?

Waking up with a scratchy, sore throat can be concerning — especially if you’re unsure of the cause. While most people may assume it is due to a cold or infection, allergies can also cause a sore throat. If you’ve been dealing with a persistent sore throat that seems to come and go with the seasons, allergens could be to blame. So, can allergies cause a sore throat? Let’s dive into the connection and what you can do to find relief.

How Allergies Can Lead To a Sore Throat

Allergies occur when your immune system overreacts to substances like pollen, dust mites, pet dander, or mold. When you’re exposed to these allergens, your body releases histamines, which trigger symptoms like sneezing, congestion, and post-nasal drip. Post-nasal drip, in particular, is a common cause of allergy-related sore throats.

When allergens irritate your nasal passages, your body produces excess mucus to flush them out. This mucus can trickle down the back of your throat, leading to irritation, scratchiness, and discomfort — especially in the morning.

Signs Your Sore Throat Might Be Due to Allergies

It’s not always easy to tell if your sore throat is caused by allergies or something else, such as a cold or viral infection. However, allergy-related sore throats often come with other telltale symptoms, including:

• Post-nasal Drip: A constant feeling of mucus in your throat, causing you to clear it frequently.
• Itchy Throat and Ears: Unlike a cold, allergies can cause itchiness in your throat, ears, and even the roof of your mouth.
• Watery, Itchy Eyes: A sore throat from allergies is often accompanied by red, watery, and itchy eyes.
• No Fever or Body Aches: Unlike viral infections, allergies do not typically cause fever, muscle aches, or fatigue.
• Seasonal Patterns: If your sore throat flares up during certain times of the year — like spring or fall — seasonal allergies could be the cause.

How to Find Relief from Allergy-related Sore Throats

Reduce Allergen Exposure

• Keep windows closed during high pollen seasons to prevent allergens from entering your home.
• Use an air purifier with a HEPA filter to remove allergens from indoor air.
• Wash bedding frequently to minimize exposure to dust mites and pet dander.

Stay Hydrated

Drinking plenty of water helps thin mucus and soothe an irritated throat. Warm teas with honey can also provide relief from scratchiness.

Try Saline Nasal Rinses

Nasal irrigation using a saline spray or a neti pot can help clear allergens from your nasal passages, reducing post-nasal drip and throat irritation.

Use Over-the-counter Allergy Medications

Antihistamines can help block histamine release and alleviate symptoms like post-nasal drip and throat irritation. Nasal corticosteroids like fluticasone (Flonase) can also reduce nasal inflammation.

Consider Allergy Treatment Options

If allergies are a persistent problem, an allergist can help identify your triggers through allergy testing and recommend long-term solutions like immunotherapy (allergy shots or sublingual immunotherapy).

When to See a Doctor

While allergy-related sore throats are common, it’s important to seek medical attention if your symptoms persist or worsen. You should see a doctor if:

• Your sore throat lasts more than two weeks
• You experience difficulty swallowing or breathing
• You have a fever, swollen glands, or other signs of infection
• Over-the-counter treatments do not provide relief
