First aid for an itchy throat

An itchy throat is irritation or a tickling sensation in the throat. It may accompany a common cold, allergic rhinitis or exposure to dry air, dust, perfume or smoke. House dust mite allergy can cause symptoms that are worse indoors, while food allergy may begin soon after eating a trigger food and can involve the mouth, skin, stomach or breathing.

The symptom does not by itself identify the cause. A runny nose, sneezing, cough, fever, rash or timing after a meal can help a clinician work out the pattern.

Drink regularly and try warm water with honey if suitable for your age and health. Gargling with warm salt water may soothe an adult throat; do not swallow the mixture. Use a humidifier that is cleaned as directed, and avoid smoke, strong scents and very spicy foods. If allergies are suspected, reduce exposure and ask a pharmacist whether allergy medication is appropriate. Do not use someone else’s prescription or combine products without checking their ingredients.

Call emergency services for sudden throat tightness, swelling of the lips or tongue, wheezing, trouble breathing, dizziness or collapse, particularly after eating or taking a medicine. Arrange medical review for a persistent sore throat, high fever, pus, dehydration, worsening pain or symptoms that keep returning. A clinician can assess infection and allergy patterns and provide an emergency plan when needed.

Ask whether the timing suggests allergic rhinitis, a food allergy or another trigger, which products are safe for you, and what symptoms should prompt emergency treatment.
