Almost everyone experiences the inconvenience of an itchy throat once in a while. Having this symptom is a common sign of hay fever and other allergies or of a viral or bacterial infection. It is usually possible to manage them with simple over-the-counter (OTC) treatments and home remedies.

What causes itchy throat?
Allergic rhinitis
Allergic rhinitis, also known as hay fever, is one of the most common causes of an itchy throat. It occurs when a body overreacts to an otherwise harmless substance, releasing a chemical called histamine. Pollen, dander, dust, dust mites, and irritants like cigarette smoke or exhaust fumes are common triggers.

Your home remedies will depend on your allergens. Try using the air conditioner and air purifier rather than opening your windows if you have seasonal allergies or pollen allergies. If possible, use a filter designed for allergy sufferers.

Additionally, you should strive to keep your house as clean and fresh as possible. If you suffer from allergic rhinitis, you should regularly deep clean your mattress, carpet, and other upholstery.

Food allergies
A food allergy occurs when the body responds to certain things we eat as if they were going to harm us. The reaction usually occurs within minutes or a few hours after eating the trigger food.

An itchy mouth may be the only symptom of the allergy. They are, however, life-threatening.

Peanuts, shellfish, eggs, milk, and wheat are common trigger foods.

Drug allergies
Many people have allergies to certain medications, including penicillin and other antibiotics. These allergies can range from mild to life-threatening.

An itchy throat that occurs after taking a new medication can be a sign of a drug allergy.

Viral and bacterial infections
An itchy throat may accompany cases of tonsillitis or streptococcal tonsillitis before progressing to a more severe sore throat.

It is unlikely to worsen if it is only a cold. In addition to throat soreness, a flu infection will cause fever, body aches, and chest discomfort.

Dehydration
The body becomes dehydrated when it loses more water than it takes in. Hot weather, exercise, and illness are common causes.

Dehydration can cause a dry mouth, a temporary condition where the mouth and throat are dehydrated. The result may be an itchy throat.

Acid reflux
Some people with chronic acid reflux experience throat problems, also known as heartburn. Acid reflux occurs when stomach acid backs up into the food pipe.

A sore or itchy throat is unlikely to be the only symptom of reflux. There are also some people who suffer from silent reflux and only notice chronic, itchy throat symptoms.

Medication side effects
It is possible for some medications to cause dry coughs and itchy throats that are not caused by allergies.

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

This usually occurs shortly after starting an ACE inhibitor and is not accompanied by other common symptoms of an itchy throat.
