Sore Throat and Tonsillitis

Usually a virus, the same ones behind colds and flu. Most sore throats are better within a week without antibiotics. Strep throat is the main bacterial cause, and for people at higher risk of rheumatic fever it needs prompt treatment.

The sore throat ladder

Pain relief does most of the work. Antibiotics help a little, mainly for strep throat. Surgery is for frequent, severe tonsillitis.

  1. Step 1 · Self-careRest, fluids and soothing foodsPlenty of drinks, soft or cold foods, warm salt-water gargles for adults and older children, and no smoke.
    Works
    Comfort care while it runs its course. Without antibiotics, about 1 in 3 people are symptom-free by day 3 and about 8 in 10 by day 7
    Cost
    Free
    How long
    Usually up to a week, sometimes 10 days
    Watch for
    Not able to swallow your own saliva? That’s not a self-care sore throat.

    Ice cream counts as medicine here. Within reason.

  2. Step 2 · PharmacyParacetamol or ibuprofenTaken regularly at the right dose for a few days.
    Works
    Ease pain and fever more than a dummy tablet in trials
    Cost
    About $3–10 a pack
    How long
    A few days
    Watch for
    Ibuprofen: avoid with stomach ulcers, kidney disease or some heart conditions. No aspirin for under 16s.

    Boring, cheap, effective. The holy trinity.

  3. Step 3 · PharmacyMedicated lozenges or throat spraysNumbing or anti-inflammatory lozenges (such as benzocaine or flurbiprofen) and some antiseptic plus anti-inflammatory sprays.
    Works
    Small extra pain relief vs dummy lozenges. Flurbiprofen lozenges caused side effects (such as mouth irritation) in 3–5 in 10 users in trials
    Cost
    About $8–15
    How long
    As needed for a few days
    Watch for
    Not a substitute for proper pain relief. Check age limits on the pack.

  4. Step 4 · PrescriptionAntibiotics (usually penicillin) for likely strep throatYour GP scores your symptoms (fever, pus on the tonsils, tender neck glands, no cough) and may take a throat swab.
    Works
    About 51 in 100 symptom-free by day 3, vs 34 in 100 without; overall they shorten the illness by about 16 hours. The benefit is bigger when strep is confirmed
    Cost
    Under the $25 PBS co-payment
    How long
    5–10 days, as prescribed
    Watch for
    Diarrhoea, rash, thrush. If strep is confirmed, finish the course.

    Antibiotics don’t do viruses. Your throat doesn’t care how much you need to be at work.

  5. Step 5 · PrescriptionA single dose of steroid for severe painSometimes offered for very painful throats, often alongside antibiotics.
    Works
    About twice as many people pain-free at 24 hours, and pain goes about half a day sooner
    Cost
    Under the $25 PBS co-payment
    How long
    One dose
    Watch for
    Not routinely recommended in UK guidelines because safer options exist. Mostly tested in adults.

    One tablet, one day sooner. A niche but real option.

  6. Step 6 · SpecialistEar, nose and throat surgeon (tonsillectomy)For frequent, severe tonsillitis: 7 or more episodes in a year, 5 a year for 2 years, or 3 a year for 3 years.
    Works
    In a UK trial of adults, surgery halved the number of sore-throat days over 2 years, including recovery time
    Cost
    Free in public hospitals (waits apply); private costs vary
    How long
    About 2 weeks of recovery
    Watch for
    Painful recovery. Bleeding afterwards affected up to 1 in 5 adults in the trial, and some needed to return to hospital.

    Two rough weeks to swap for two easier years. Do the maths with your surgeon.

Costs are rough Australian prices in November 2026 and vary by pharmacy and provider. PBS co-payment: $25, or $7.70 with a concession card. Results are typical figures from trials, not promises.

Popular, heavily marketed or often asked about, but the evidence is weak or says no.

What you can do

See your GP if

Call 000 or your local emergency number for trouble breathing, drooling or being unable to swallow saliva, trouble opening your mouth, a muffled voice with severe pain on one side (possible throat abscess, called quinsy), or a stiff neck with fever or confusion.

Common questions

Is it viral or strep?

You can’t tell for sure by looking. Strep is more likely with fever, pus on the tonsils, tender neck glands and no cough. A cough, runny nose and hoarse voice point to a virus. About 1 in 5 sore throats are caused by strep.

What is tonsillitis?

Infection and swelling of the tonsils at the back of the throat, usually from a virus and sometimes strep. Tonsils look red and swollen, sometimes with white spots, and swallowing hurts.

How is a sore throat diagnosed?

Your GP looks at your throat, feels your neck and asks about fever and cough, often using a simple symptom score. A throat swab can confirm strep, which matters most for people at higher risk of rheumatic fever.

Why didn’t my doctor give me antibiotics?

For most people they make little difference: about 16 hours less illness on average, plus a chance of side effects. Your doctor may suggest pain relief and returning if it isn’t improving.

Why do rheumatic fever and strep matter in Australia?

Untreated strep can trigger rheumatic fever, which can damage heart valves. Aboriginal and Torres Strait Islander children in rural and remote areas are at highest risk, so prompt treatment of sore throats and skin sores matters.
