Which signs and symptoms can Itchy Throat usually be associated with?

Often, an itchy throat is not the only symptom that a person may be dealing with. Symptoms that occur along with an itchy throat vary with the underlying cause.

Itchy throats caused by allergic rhinitis may be accompanied by any combination of the following symptoms:

  • Runny or stuffy nose
  • Sinus pressure
  • Itchy eyes and skin
  • Sneezing
  • Tiredness
  • Swollen, red, or watery eyes

When caused by drug or food allergies, an itchy throat may occur together with any number of symptoms from mild to needing immediate emergency medical treatment.

The symptoms that can occur with an itchy throat due to drug and food allergies include:

  • A red itchy rash known as hives
  • Redness of the skin around the eyes
  • Itchy ears
  • Nausea and vomiting
  • Diarrhea
  • Stomach pain
  • Swelling of the lips, tongue, and throat
  • Trouble breathing or swallowing
  • A sense of doom
  • Drop in blood pressure
  • Loss of consciousness

It can be difficult to distinguish an itchy throat caused by allergic rhinitis from one caused by illness. In both instances, it may be accompanied by nasal congestion or sneezing.

However, if the itchy throat is caused by an acute illness, it will probably be short-lived and accompanied by a combination of the following symptoms:

  • Fever
  • Swollen glands
  • Muscle aches
  • Weakness
  • A headache
  • A cough
  • Nasal congestion

When the itchy throat is caused by dehydration, other symptoms can include

  • Extreme thirst
  • Dry mouth
  • Infrequent dark urine

If the itchy throat is caused by reflux or heartburn, other symptoms may include:

  • Difficulty or pain when swallowing
  • Burning sensation in chest or throat
  • Gas
  • Inflamed voice box
  • Worn down tooth enamel
  • Inflamed gums
  • A bad taste in the mouth


What causes Itchy Throat?

Irritated itchy throats can be caused by a wide variety of factors. Likely causes of an itchy throat include the following:

Allergic rhinitis

A common cause of itchy throat is allergic rhinitis, which is also known as hay fever.

Also known as hay fever, allergic rhinitis may be one of the most common causes of an itchy throat.

Allergic rhinitis happens when the body overreacts to an otherwise harmless substance, releasing a chemical called histamine that causes these overreactions.

Common triggers include pollen, dander, dust, and irritants such as cigarette smoke or exhaust fumes.

Food allergies

Allergic reactions to food happen when the body reacts to certain things we eat as if they were going to harm the body. Reactions generally develop within minutes or a few hours after consuming the trigger food.

The allergy may be mild with symptoms stopping with an itchy throat or mouth. However, they can be life-threatening.

Common trigger foods include peanuts, shellfish, eggs, milk, and wheat.

Drug allergies

Many people suffer from allergies to certain medications including penicillin and other antibiotics. The severity of the allergy will range from mild to life-threatening.

Symptoms of a drug allergy can include an itchy throat that starts shortly after taking a new medication.

Bacterial and viral infections

Strep throat or bacterial cases of tonsillitis may start with an itchy throat before progressing to a more severe sore throat.

Viruses such as the common cold or the flu virus can both cause an itchy throat.

If it is just a cold, the itchy throat is unlikely to progress past being mildly sore. If a person has a flu infection, their throat soreness will be more severe and accompanied by fever, body aches, and chest discomfort.


Dehydration occurs when the body loses more water than it takes in. It is common during hot weather, after exercise, or during illness.

Dehydration can cause a dry mouth, a temporary condition where the mouth and throat don’t have enough saliva. This may cause an itchy feeling in the throat.

Acid reflux

Also known as heartburn, some people with chronic acid reflux experience throat problems. Acid reflux happens when stomach acid backs up from the stomach into the food pipe.

An itchy or sore throat is unlikely to be the only symptom of reflux. However, some people have a condition called silent reflux and may only notice a chronic, itchy throat as a symptom.

Medication side effects

Some medications may cause dry coughs and itchy throats that are not due to allergic reactions.

People taking ACE inhibitors for high blood pressure should be aware that ACE inhibitors may cause an itchy throat and dry cough.

Most often, these symptoms begin shortly after starting an ACE inhibitor and are not accompanied by other symptoms commonly experienced with an itchy throat.

Conditions mentioned above are some common causes of itchy throat. Consult with your doctor for an accurate diagnosis.
