What Is the Best Over-the-Counter Medicine for Sore Throat?
For most adults, ibuprofen 400mg is the most effective over-the-counter medicine for sore throat because it reduces both pain and the underlying inflammation at the same time. Paracetamol is a strong alternative, and medicated lozenges containing benzocaine (a local anaesthetic that numbs the throat) work faster but for shorter periods. This guide explains exactly which option is best for your situation, what the evidence says, and the mistakes I see people make every week at my pharmacy counter.
Why the Cause of Your Sore Throat Changes What You Should Take
Before you reach for anything, it helps to understand what is actually happening. The pain you feel when swallowing comes from inflammation of the pharynx (the back of the throat). That inflammation has different causes, and the cause changes the best treatment approach.
The vast majority of sore throats, around 85-90%, are caused by viral infections. Cold viruses, influenza, and COVID-19 can all cause throat inflammation. [1] Viral sore throats cannot be treated with antibiotics. Antibiotics have zero effect on viruses. What they respond to is time, rest, good hydration, and the right pain-relief medicines.
Bacterial sore throats, typically caused by Streptococcus pyogenes (commonly called strep throat), make up around 10-15% of adult cases. [2] These do respond to antibiotics, but they still benefit from OTC pain relief in the meantime. If you have a fever above 38.3°C (101°F), white patches on your tonsils, and no cough, bacterial infection is more likely and you should see a doctor.
💡 Key Takeaway
Most sore throats are viral. OTC medicines treat the pain and inflammation effectively while your immune system clears the infection. Do not demand antibiotics for a standard viral sore throat.
The Best OTC Medicines for Sore Throat: What Each One Actually Does
There are three main categories of OTC medicine available for sore throat relief. Each works differently and each has a best-fit situation.
1. Ibuprofen (NSAIDs) — Best Overall for Most Adults
Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) that blocks the COX enzyme (cyclooxygenase), which the body uses to produce prostaglandins (the chemical messengers that trigger pain and swelling). [3] By reducing prostaglandin production, ibuprofen addresses the inflammation causing the throat pain, not just the pain sensation itself.
The standard adult dose is 200mg to 400mg every 6 to 8 hours with food. Clinical trials comparing ibuprofen and paracetamol for sore throat consistently show ibuprofen provides greater pain reduction at equivalent doses, precisely because of this anti-inflammatory action. [4]
Who should not take ibuprofen: people with stomach ulcers, severe kidney disease, asthma triggered by NSAIDs, or women in the third trimester of pregnancy. Take it with food to protect your stomach lining.
2. Paracetamol (Acetaminophen) — Safest Option for Most People
Paracetamol reduces pain signals in the brain and lowers fever. It does not reduce inflammation at the source, which is why it is slightly less targeted for inflammatory throat pain than ibuprofen. But it is the safest option for children, pregnant women, people with stomach problems, and most elderly patients.
Standard adult dose is 500mg to 1000mg every 4 to 6 hours, up to 4000mg per 24 hours. Do not exceed this. The point I make at my counter all the time: many people take paracetamol alongside cold and flu combination tablets without realising those tablets already contain paracetamol. Always check the ingredients of any other medicine you are taking simultaneously. [5]
3. Medicated Lozenges and Throat Sprays — Fastest Local Relief
Lozenges containing benzocaine (a local anaesthetic) numb the throat directly. They do not reduce inflammation or treat any infection. What they do is provide rapid, localised relief in 5 to 10 minutes, which is helpful before meals or when the pain spikes at night. The effect lasts 30 to 60 minutes. Brands like Strepsils, Difflam, and Cepacol are commonly available.
Menthol-based lozenges give a cooling sensation and mild relief for mild throat irritation. They work well for early-stage soreness or throat dryness.
Throat sprays containing benzydamine (an anti-inflammatory) can also reduce throat inflammation locally and are particularly useful when swallowing tablets is painful.
| Medicine | Best For | How Long to Work | Avoid If |
|---|---|---|---|
| Ibuprofen 400mg | Moderate to severe inflammatory throat pain | 30–60 minutes | Stomach ulcer, kidney disease, late pregnancy |
| Paracetamol 500–1000mg | Mild-moderate pain; children; pregnancy | 30–45 minutes | Liver disease, alcohol dependence |
| Benzocaine lozenges | Fast localised numbing; pre-meal relief | 5–10 minutes | Allergy to local anaesthetics; children under 5 |
| Benzydamine spray | Local anti-inflammatory; when swallowing tablets is hard | 15–30 minutes | Children under 6 (consult pharmacist for dose) |
💡 Key Takeaway
Ibuprofen is first choice for most adults. Paracetamol when ibuprofen is contraindicated. Add a numbing lozenge for faster onset relief in the meantime. You can use lozenges and ibuprofen together safely.

Home Remedies That Actually Help (And One That Doesn't)
Home remedies are not a replacement for OTC medicines when symptoms are moderate to severe. But several have good evidence and work well alongside them.
Warm salt water gargles are the most evidence-supported non-drug option. Half a teaspoon of table salt dissolved in a glass of warm water, gargled for 30 seconds and spat out, reduces throat swelling (the salt draws fluid out of inflamed tissue via osmosis) and kills some surface bacteria. [7] Do this every 2 to 3 hours when symptoms are active.
Warm honey and lemon drinks genuinely reduce throat irritation. Honey has antimicrobial properties and coats the inflamed mucosa. One randomised trial found honey was more effective than a placebo for reducing throat symptoms in upper respiratory tract infections. [8] Do not give honey to children under 12 months old, as it carries a risk of infant botulism.
Staying well hydrated is not optional. Dehydration makes throat pain worse, thickens mucus, and slows the immune response. Warm fluids work best. Cold drinks numb the throat temporarily but can increase irritation in some people.
The one that doesn't work as well as claimed: cold-and-flu combination sachets with paracetamol, vitamin C, and decongestant. They provide symptom relief from the paracetamol. But the doses of vitamin C in those sachets are too small to have meaningful therapeutic effect on an established sore throat. The marketing is ahead of the evidence.

The most dangerous habit I see every single day is taking paracetamol for every symptom without asking why the symptom is there. A headache, body aches, slight fever — patients reach for paracetamol as a reflex. What most people do not know is that these recurring symptoms are often signalling stress, poor sleep, or low iron — things paracetamol cannot fix. Meanwhile the liver processes every milligram silently. I have seen patients stack Panadol, Emzor, and a combination cold tablet in the same day without realising they all contain paracetamol, sometimes totalling over 3,000mg before they reach my counter. I always tell them: the day you take paracetamol for stomach pain is the day it has stopped being used correctly.
💡 Key Takeaway
Salt water gargles and honey drinks are legitimate supportive care. Use them alongside, not instead of, appropriate OTC pain relief when your symptoms are moderate to severe.

When to See a Doctor Instead of Self-Treating
Most sore throats resolve within 7 days without medical intervention. [9] But certain signs tell you a doctor is needed.
See a doctor if you have a fever above 38.5°C that does not come down with ibuprofen, white patches or pus on the tonsils, difficulty opening your mouth or a muffled voice (which can signal a peritonsillar abscess, a pocket of infection around the tonsil), swollen glands in the neck that are tender to touch, a skin rash appearing at the same time as the throat pain (possible scarlet fever in children), or symptoms that get worse after day 3 rather than better.
Children under 3 with sore throat and fever should always be assessed by a doctor rather than self-treated. And in adults, a sore throat that persists beyond 3 weeks without any obvious cause needs an ENT evaluation to rule out other pathology.
In my experience at the pharmacy counter, the patients I worry about most are the ones who come on day 6 saying the sore throat has been getting steadily worse and they assumed it would resolve on its own. That trajectory, getting worse after day 3, is a clinical signal that something else is going on.

Worsening after day 3, high fever, throat swelling, or a rash alongside sore throat are all signs to see a doctor rather than self-treat.
Sore Throat Myths vs Facts
❌ Myth
"A sore throat always needs antibiotics to get better."
✓ Fact
85-90% of sore throats are viral and will not respond to antibiotics at all. [1] OTC pain relief and time are the correct treatment for the majority of cases.
❌ Myth
"Throat lozenges treat the infection."
✓ Fact
Lozenges containing benzocaine numb the throat locally. They don't reduce inflammation, kill viruses, or treat bacterial infections. They're pain management tools, not antimicrobials. [3]
❌ Myth
"You can't take ibuprofen and paracetamol together for a sore throat."
✓ Fact
Ibuprofen and paracetamol work through different mechanisms and can be taken together safely in adults, staggered every 3 hours. They are not the same drug and do not interact. [10]
Choosing the Right OTC Medicine for Different Situations
Sore throat is one of the most common reasons people reach for an over-the-counter medicine, but the principles that apply here — matching the right drug to the right situation — apply across dozens of conditions. Our complete guide to over-the-counter medicines covers every major OTC category with the same pharmacist-verified detail you just read.
If your sore throat is coming alongside a dry, persistent cough, it is worth reading our guide on the best OTC medicine for cough, since several cough formulations also contain throat-soothing ingredients that can treat both symptoms simultaneously.
And if your throat irritation seems connected to seasonal allergies rather than a viral infection (the soreness appears at certain times of year, comes with watery eyes or sneezing, and doesn't worsen after day 3), our post on the best OTC medicine for allergies may point you toward a more effective treatment approach.
◆ Pharmacist Verdict
If I had one recommendation for a straightforward sore throat in a healthy adult: ibuprofen 400mg with food, every 6 to 8 hours. Add a benzocaine lozenge when you need faster relief before eating or at night. And for anyone who can't take ibuprofen, paracetamol 1000mg is entirely adequate and safe. What I want you to take away from this article is simpler than people expect: most sore throats don't need a doctor. They need rest, hydration, the right pain relief taken at the right dose, and time.
But 'most' is not 'all'. If you are getting worse on day 3 or 4 rather than better, come and see me or a doctor. The throat infection that turns into a peritonsillar abscess is not something paracetamol will fix.

Frequently Asked Questions
For most adults, ibuprofen 400mg is the most effective OTC option because it reduces both pain and inflammation at the source. Paracetamol is a good alternative if you cannot take ibuprofen. Benzocaine lozenges provide faster but shorter-lasting local relief and can be used alongside either tablet.
Ibuprofen is generally better for sore throat because it reduces inflammation as well as pain. However, if you have a stomach ulcer, are pregnant, or cannot take anti-inflammatory medicines, paracetamol is the safer choice. You can stagger both safely in adults, every 3 hours alternating, as they work through different mechanisms and do not interact.
Yes. Benzocaine lozenges numb the throat locally while ibuprofen reduces the underlying inflammation systemically. They work through different mechanisms and are safe to combine in most adults. This combination gives you faster onset relief from the lozenge plus longer-lasting anti-inflammatory effect from the ibuprofen.
Antibiotics are only needed when a sore throat is caused by bacterial infection, typically strep throat. Signs that suggest a bacterial cause include severe throat pain, fever above 38.3°C, white patches on tonsils, and no cough. A sore throat that lasts more than 7 days or worsens after day 3 should be assessed by a doctor. Self-prescribing antibiotics for a viral sore throat has no benefit and contributes to antibiotic resistance.
Yes, for mild throat irritation. Warm salt water gargles, honey drinks, and good hydration all support recovery. But for moderate to severe sore throat pain, these work best alongside OTC pain relief rather than as a replacement. If swallowing is painful enough to prevent you from drinking adequately, you need medical review.
Lozenges containing benzocaine provide the fastest and strongest numbing effect, working within 5 to 10 minutes. Brands including Strepsils, Difflam, and Cepacol are widely available. Menthol lozenges offer a milder cooling sensation suitable for mild irritation. Benzocaine lozenges are not recommended for children under 5 years.
