Sore Throat

Your nose and throat produce up to a quart of mucus each day to keep you keep tissues from drying out and to clear away bacteria. Normally, you swallow mucus and don’t even notice it’s there. However, allergies can cause mucus to thicken and build up, resulting in postnasal drip.

Causes & Symptoms

Allergy-induced sore throat occurs when contact with an allergen causes postnasal drip. Usually the culprit is pollen, which is typically a seasonal allergy, but other allergens that can cause postnasal drip include smoke, dust mites, mold, mildew and pet dander.

Postnasal drip can cause sore throat, cough, trouble swallowing, difficulty speaking and scratchiness. Your throat will likely feel raw from coughing or from particles entering the respiratory system.


There are several methods of caring for allergy-induced sore throat that can provide immediate relief.

  • Gargle warm salt water. Stir one teaspoon of salt into eight ounces of warm water. The relief is temporary, but it does help clear mucus away.
  • Drink lots of fluids, especially water. It is important to stay hydrated when you don’t feel well. Tea with honey or lemon can help relieve a scratchy or sore throat, and the steam from hot tea can help clear sinuses.
  • Take antihistamine to help clear mucus OR ibuprofen to relieve pain. PLEASE NOTE: Some antihistamines contain a fever reducer, which cannot be combined with ibuprofen. Be careful when taking medicines and read labels carefully.
  • Clear your sinuses with a nasal rinse from a Neti Pot or similar instrument. This helps clear postnasal drip.

The best way to prevent allergy-induced sore throat is to avoid allergens. This is not always possible, however, so many patients opt for immunotherapy allergy treatment. Allergy shots and allergy drops help your body build an immune response to allergens to reduce or stop allergy symptoms.
