Sore Throat Remedies: What Works and What Doesn’t

Why a sore throat hurts

Viral infections cause most sore throats, and the pain comes from inflammation of the lining of the throat and tonsils. The pain peaks on days 2–3 and fades over a week. The goals of treatment are to reduce pain and keep you hydrated while the immune system does the work. For the medical background see pharyngitis.

Painkillers: the most effective remedy

Paracetamol (acetaminophen) and ibuprofen reduce pain and fever. Ibuprofen is somewhat more effective for sore throat pain in many studies.
Take regular doses as directed for the first couple of days rather than waiting for the pain to peak.
Check you are not taking duplicate products (for example, cold and flu remedies that contain paracetamol).
Do not give aspirin to children and teenagers under 16.
People with stomach ulcers, kidney disease, asthma or on blood thinners should check before using ibuprofen.

Fluids, honey and warm drinks

Staying hydrated keeps the throat moist and helps swallowing. Warm drinks (tea, broth) and cold treats (ice lollies, ice chips) both ease pain. A spoonful of honey in tea or on its own soothes the throat and has some evidence for cough relief, but should not be given to babies under one year because of the risk of botulism. Avoid very hot, acidic or alcoholic drinks, which irritate the throat.

Salt-water gargles

Gargling with warm salt water (about half a teaspoon of salt in a glass of warm water) is cheap and safe for older children and adults. It may reduce swelling and bring temporary relief by drawing fluid from the tissues, though evidence is limited. Spit it out rather than swallowing. Mouthwashes with antiseptics can sting and have not been shown to shorten the illness.

Lozenges, sprays and numbing products

Throat lozenges stimulate saliva and provide short-term relief; those with local anaesthetic (benzocaine, lidocaine) or an anti-inflammatory (flurbiprofen) numb or soothe the throat more.
Sprays with anaesthetic work quickly but wear off in minutes.
Sugar-free options are better for the teeth.
Lozenges are not suitable for children under six years because of the choking risk.
Products labelled “antibacterial” will not treat a viral infection.

Steroids for severe sore throat

A Cochrane review found that corticosteroids (for example a single dose of dexamethasone) increase the chance of pain resolution in 24–48 hours in people with a severe sore throat, particularly if they also receive antibiotics for a bacterial infection. Because of possible side effects, they are prescribed selectively by a doctor and are not an over-the-counter remedy.

What about antibiotics?

Antibiotics only help if the sore throat is caused by bacteria, mainly group A strep, and a test is recommended when your symptoms fit. For viral sore throat they do not shorten illness and cause side effects. If you are prescribed an antibiotic, take the full course. See strep throat.

Remedies with little or no evidence

Vitamin C, zinc and echinacea taken after symptoms begin: little or no effect on a sore throat.
Apple cider vinegar, garlic, raw onion and gargling with bleach or hydrogen peroxide: not supported; some can burn.
Herbal sprays and “immune-boosting” supplements: evidence is limited.
Leftover antibiotics: do not use them.
Smoking: delays healing and irritates the throat.

Comfort measures

Rest and sleep with the head slightly raised.
Use a humidifier or inhale steam from a hot shower.
Choose soft, bland foods: soup, yoghurt, eggs, porridge, smoothies.
Avoid smoke, strong fragrances and shouting.
Stay home while you have a fever, and wash hands often.

Children and sore throat

Use age-appropriate doses of paracetamol or ibuprofen, offer fluids and cold treats, and avoid lozenges in under-sixes. Honey is fine after the first birthday. Seek medical advice if your child has trouble swallowing or breathing, refuses to drink, drools, has a high fever or looks very unwell.

When to see a doctor

Severe pain with high fever and no cough.
Difficulty breathing, swallowing or opening the mouth, or drooling (urgent).
Symptoms for more than a week, or worsening after initially improving.
Recurrent sore throats, or a persistent one-sided sore throat.
Hoarseness for more than four weeks, a neck lump or unexplained weight loss.
Weakened immunity or recent contact with strep.

Three common situations

Sore throat and runny nose on day 2: painkiller, fluids, honey and gargles; expect improvement in several days.

Severe sore throat with fever and no cough: see a doctor for a strep test.

Sore throat for three weeks: have it examined; consider allergy, reflux, smoking or another cause.

Key points to remember

The best remedies for a sore throat are regular simple painkillers, fluids and rest, supported by gargles, honey and lozenges. Avoid antibiotics unless a bacterial cause is confirmed, and seek care for warning signs or symptoms lasting beyond a week.
