Can Allergies Cause Sore Throat?

Yes, allergies are one of many causes of sore throats. Other common sore throat causes include:

How Allergies Can Cause a Sore Throat

The most common way that allergies cause a sore throat is because of postnasal drip. When you have a runny, stuffy nose, not all the mucus comes out through your nose. Some of it drips down your throat, which can cause you to have to cough or clear your throat.

If you have a lot of postnasal drip, the constant throat-clearing and coughing can lead to a sore throat that does not want to go away.

Sore Throat Allergy Symptoms

If your sore throat is caused by allergies, your symptoms may include:

  • Excessive swallowing

  • Coughing

  • Trouble speaking

  • Throat irritation and clearing

  • Scratchy throat

  • Sneezing

  • Congestion

  • Runny nose

  • Itchy, watery eyes and nose

Sore Throat Allergy Treatment

There are many different ways to treat sore throat allergies. You may need to try multiple types of treatments to get the best results.

Sore Throat Allergy Home Remedies

Home remedies for sore throats from allergies can be used alone or together with other treatments for the most effective relief. Common home remedies for sore throat allergies include:

  • Drink plenty of water. Fluids keep your throat moist and thin out mucus, while dryness can worsen sore throats.

  • Take advantage of warm fluids. Drinking hot herbal tea or eating hot soup can soothe sore throats, as can gargling with warm saltwater. Avoid coffee and other caffeinated drinks, though, because caffeine can be an irritant.

  • Use a neti pot to flush mucus out of your sinuses. Always use sterile water with the specially designed saline mixture, because tap water can cause problems in your nasal cavities.

Sore Throat Allergy Medicine

Many allergy medications are available over the counter, while others require a prescription. There is a wide variety of allergy medication types.


Antihistamines block histamine, a chemical released by your immune system during an allergic reaction that causes symptoms, including itching. Many different forms of antihistamines are available, often over the counter.

Pills and liquids:

  • Diphenhydramine (Benadryl)

  • Cetirizine (Zyrtec)

  • Fexofenadine (Allegra)

  • Loratadine (Alavert, Claritin)

  • Levocetirizine (Xyzal)

  • Desloratadine (Clarinex)

Nasal sprays:

  • Azelastine (Astelin, Astepro)

  • Olopatadine (Patanase)


  • Glycerin, hypromellose, polyethylene glycol (Visine)

  • Ketotifen (Alaway, Zaditor)

  • Pheniramine and naphazoline (Opcon-A, others)

  • Olopatadine (Pataday, Patanol, Pazeo)


Decongestants can help relieve nasal congestion, which may help reduce postnasal drip and sore throats. They can have a lot of side effects, aren’t recommended for long-term use, and shouldn’t be taken by people with certain medical conditions.

Pills and liquids:

  • Cetirizine and pseudoephedrine (Zyrtec-D Allergy Plus Congestion)

  • Fexofenadine and pseudoephedrine (Allegra-D)

  • Desloratadine and pseudoephedrine (Clarinex-D)

  • Loratadine and pseudoephedrine (Claritin-D)

Nasal sprays and drops:

  • Tetrahydrozoline (Tyzine)

  • Oxymetazoline (Afrin)


Corticosteroids help to suppress allergy-related inflammation. They can cause a lot of side effects, especially when used long-term.

Nasal sprays:

  • Budesonide (Rhinocort)

  • Fluticasone propionate (Flonase Allergy Relief)

  • Triamcinolone (Nasacort Allergy 24 Hour)

  • Fluticasone furoate (Flonase Sensimist)

  • Mometasone (Nasonex)

  • Ciclesonide (Zetonna)

  • Beclomethasone (Qnasl)


  • Fluticasone (Flovent)

  • Budesonide (Pulmicort Flexhaler)

  • Beclomethasone (Qvar Redihaler)

  • Ciclesonide (Alvesco)

  • Mometasone (Asmanex Twisthaler)

Pills and liquids:

  • Prednisolone (Prelone)

  • Methylprednisolone (Medrol)

  • Prednisone (Prednisone Intensol, Rayos)

Leukotriene Inhibitors

Leukotriene receptor antagonists block symptom-causing chemicals called leukotrienes. Montelukast (Singulair) is available by prescription only and may cause side effects.

Mast Cell Stabilizers

When antihistamines are not working well or are not well tolerated, mast cell stabilizers can block the release of chemicals in the immune system that contribute to allergic reactions. They usually need to be taken for several days before the full effects are felt.

Sore Throat Allergy Shots

If you find out exactly what you are allergic to, you may be a candidate for allergy shots, which are usually given once or twice a week for about 6 months.

Allergy shots work by injecting small amounts of one or more allergens into your body until your immune system eventually gets used to it and stops reacting. You may need maintenance shots for an additional 3 to 5 years to maintain your resistance to the allergen.

Frequently Asked Questions

Can You Get a Scratchy Throat from Allergies?

Yes. Not only can your throat get irritated from the postnasal drip, but the allergens can cause your throat to itch or feel scratchy.

How Long Does a Sore Throat from Allergies Last?

Unfortunately, a sore throat from allergies may last as long as the rest of your allergy symptoms. For some people, sore throat allergies can become a chronic problem. Talk to a doctor about your best options for treating your allergy symptoms, including a sore throat.

How Do You Get Rid of a Sore Throat from Allergies?

There are a few ways to handle a sore throat from allergies:

  • Try home remedies like drinking lots of water and using a neti pot.

  • Take antihistamines or other allergy medications to help lessen all your allergy symptoms.

  • Take over-the-counter pain relievers like acetaminophen (Tylenol) to help reduce your throat pain.
