Best Throat Lozenges in Australia: Strepsils, Difflam, Cepacol & More (2026 Guide)
At a Glance
Medicated lozenges containing anti-inflammatory or anaesthetic ingredients provide genuine pain relief for sore throats. For mild irritation, non-medicated options like Soothers or Butter-Menthol work well at a lower cost. Most sore throats are viral and resolve within a week — see your GP if symptoms persist beyond 7 days or are severe.
Difflam Anti-inflammatory Lozenges for the most effective medicated relief
Butter-Menthol Lozenges for affordable soothing comfort
A sore throat is one of those symptoms that sends people straight to the lozenge aisle, usually when they already feel flat and do not want to overthink it. The trouble is that throat lozenges are sold as if they all do the same job, when in practice some are mainly soothing while others contain ingredients that can make a real dent in pain and inflammation.
We compared the main Australian options by active ingredient, expected level of relief, taste, cost per lozenge, and how strong the evidence is behind each type.
How We Assessed
- •Active ingredient and mechanism: Does the lozenge contain a TGA-recognised active ingredient with evidence for sore throat relief?

- •Price per lozenge: Calculated from typical retail prices at major Australian pharmacies as of early 2026.
- •Taste and compliance: Lozenges only work if people actually use them — flavour and texture matter.
- •Suitability: Age restrictions, pregnancy considerations, and contraindications.
- •Availability: Widely stocked across Chemist Warehouse, Priceline Pharmacy, Amcal, Terry White Chemmart, and supermarkets.
How Throat Lozenges Work
Not all throat lozenges are created equal. They fall into four broad categories based on their mechanism of action, and understanding this helps you pick the right one for your symptoms.
Antiseptic lozenges
These contain ingredients like amylmetacresol and dichlorobenzyl alcohol (as found in Strepsils Original) that kill or inhibit the growth of bacteria and viruses in the throat. They are best suited for the early stages of a sore throat when you want to reduce the microbial load. However, since most sore throats are viral, the direct germ-killing effect may be modest — the real benefit often comes from the soothing action of sucking on the lozenge itself.
Anti-inflammatory lozenges
These are the heavy hitters. Lozenges containing benzydamine (Difflam) or flurbiprofen (Strepsils Intensive) work by reducing inflammation directly at the throat tissue. They provide genuine, measurable pain relief backed by clinical evidence. If your throat is noticeably swollen and painful, these are typically the most effective OTC option.
Anaesthetic lozenges
Products like Cepacol contain local anaesthetic agents or numbing compounds that temporarily block pain signals from the throat. The relief is fast but relatively short-lived — typically 20 to 30 minutes per lozenge. They are useful when you need quick relief for a specific task like eating or giving a presentation.
Soothing (non-medicated) lozenges
Products like Soothers and Butter-Menthol rely on ingredients such as menthol, eucalyptus oil, and honey to soothe irritation through lubrication and a cooling sensation. They do not contain TGA-scheduled active ingredients, so they are more like therapeutic confectionery. That said, the physical act of sucking a lozenge stimulates saliva production, which naturally lubricates and soothes the throat — so even non-medicated lozenges provide genuine comfort.
Our Top Picks
Best Medicated Lozenge: Difflam Anti-inflammatory Lozenges
Difflam lozenges contain benzydamine hydrochloride, a non-steroidal anti-inflammatory drug (NSAID) that works directly on inflamed throat tissue. Clinical studies support benzydamine's effectiveness for reducing sore throat pain and swelling. Available in several flavours including honey & lemon and mint, they are pleasant enough to use regularly throughout the day.
Difflam Anti-inflammatory Lozenges
Anti-inflammatory throat lozenges containing benzydamine hydrochloride for relief of sore throat pain and inflammation.
Pros
- Contains a clinically proven anti-inflammatory (benzydamine)
- Targets both pain and swelling directly at the throat
- Available in multiple flavours
- Well-tolerated by most adults
Cons
- More expensive than non-medicated options (around $0.50-0.80 per lozenge)
- Not suitable for children under 6 years
- Can cause temporary mouth or tongue numbness
Best Antiseptic Lozenge: Strepsils Sore Throat Lozenges
Strepsils is arguably Australia's most recognised throat lozenge brand. The Original formula contains two antiseptic agents — amylmetacresol and 2,4-dichlorobenzyl alcohol — which have been shown to have antibacterial and antiviral activity. The range is extensive, with options including Strepsils Plus (with anaesthetic), Strepsils Honey & Lemon, and Strepsils Intensive (a separate anti-inflammatory product). For a reliable, well-priced antiseptic lozenge, the original is hard to beat.
Strepsils Sore Throat Lozenges
Medicated lozenges for temporary relief of sore throat pain and discomfort. Contains amylmetacresol and dichlorobenzyl alcohol.
Pros
- Dual antiseptic action against bacteria and viruses
- Huge range of flavours and variants
- Widely available — pharmacies, supermarkets, petrol stations
- Affordable at around $0.30-0.50 per lozenge
Cons
- Antiseptic action may be limited for viral sore throats
- Original flavour can be medicinal tasting
- Does not reduce inflammation like Difflam or Strepsils Intensive
Best Soothing Lozenge: Soothers Throat Drops
Soothers are technically throat drops rather than medicated lozenges, containing menthol and eucalyptus oil along with pleasant flavourings like honey and lemon. They work by stimulating saliva flow and providing a cooling menthol sensation that eases throat discomfort. They will not kill bacteria or reduce inflammation, but for a mildly scratchy throat — or when you simply want soothing comfort without medication — they are a great choice. They also taste noticeably better than most medicated options.
Soothers Throat Drops
Soothing throat drops with menthol and eucalyptus oil for temporary relief of sore throat discomfort. Non-medicated option.
Pros
- Pleasant taste — multiple flavour options
- Affordable (around $0.15-0.30 per drop)
- Available in pharmacies and supermarkets
- Suitable for mild throat irritation
- No significant drug interactions or side effects
Cons
- Not medicated — will not treat infection or reduce inflammation
- Contains sugar (not ideal if sucking multiple per day)
- Less effective for severe sore throats
Best Anaesthetic Lozenge: Cepacol Antibacterial Lozenges
Cepacol lozenges deliver a noticeable numbing effect that kicks in quickly — you can feel it working within minutes. They contain cetylpyridinium chloride, an antibacterial agent, and some variants also include a local anaesthetic. The numbness typically lasts around 20 to 30 minutes, making them ideal when you need targeted relief for swallowing, eating, or talking. They are widely available and sit in the mid-price range.
Cepacol Antibacterial Throat Lozenges
Dual-action antibacterial and anaesthetic throat lozenges containing cetylpyridinium chloride for sore throat relief.
Pros
- Fast-acting numbing effect
- Antibacterial agent may help reduce throat bacteria
- Good for temporary relief before meals or presentations
- Widely available at Australian pharmacies
Cons
- Numbing effect is short-lived (20-30 minutes)
- Some people dislike the numbing sensation
- Not as effective for inflammation as Difflam
- Slightly medicinal taste
Best Value: Butter-Menthol Throat Lozenges
Butter-Menthol lozenges are an Australian classic. They contain menthol as their key soothing ingredient and come in the familiar butter-flavoured drop that generations of Australians have grown up with. At around 15 to 25 cents per lozenge, they are among the most affordable throat soothing options. While they do not contain medicated active ingredients, menthol provides a genuine cooling and mildly anaesthetic effect on the throat. For everyday throat comfort and value for money, they remain a solid choice.
Butter-Menthol Throat Lozenges
Traditional Australian throat lozenges with menthol for soothing relief of minor throat irritation.
Pros
- Excellent value for money
- Iconic Australian taste — most people already know if they like them
- Menthol provides a genuine cooling sensation
- Available everywhere — pharmacies, supermarkets, convenience stores
Cons
- Not medicated — limited effectiveness for severe sore throats
- Contains sugar
- Only one flavour option
Honourable Mention: Strepsils Intensive
Strepsils Intensive is worth a special mention because it contains flurbiprofen 8.75mg — a proper NSAID that provides anti-inflammatory pain relief similar to Difflam. It is a strong option for more severe sore throat pain and is backed by good clinical evidence. It sits at a higher price point and is pharmacist-only in some formulations, but if Difflam is not available, Strepsils Intensive is an excellent alternative.
Strepsils Intensive (Flurbiprofen 8.75mg)
Anti-inflammatory throat lozenges containing flurbiprofen for targeted relief of severe sore throat pain and swelling.

Medicated vs Non-Medicated Lozenges: When Each Is Appropriate
This is perhaps the most important distinction to understand when choosing a throat lozenge. Getting it right can save you money and help you get better relief.
When to choose medicated lozenges
- •Your throat is noticeably painful, red, or swollen.
- •You are struggling to swallow food or drinks comfortably.
- •Pain is interfering with sleep or daily activities.
- •You are in the first 2-3 days of a sore throat when symptoms tend to peak.
- •You prefer targeted relief over oral painkillers like paracetamol or ibuprofen.
Combining Treatments
Medicated lozenges can generally be used alongside oral paracetamol or ibuprofen for more comprehensive pain relief. However, avoid combining Difflam or Strepsils Intensive lozenges with oral NSAIDs (like Nurofen) without checking with your pharmacist first, as this may increase the risk of side effects.
When non-medicated lozenges are fine
- •Your throat is mildly scratchy or dry rather than truly painful.
- •You are recovering from a cold and just want ongoing comfort.
- •Your sore throat is caused by dry air, air conditioning, or mild overuse of your voice.
- •You want something to suck on during a long flight or in a dry office environment.
- •You prefer to avoid medication where possible.
What Causes a Sore Throat — and When Lozenges Help
Understanding why your throat hurts helps you choose the right treatment — and know when to skip the lozenges and see a doctor instead.
Viral sore throats (most common)
Around 80% of sore throats are caused by viral infections — the common cold, influenza, or COVID-19. These typically come with other symptoms like a runny nose, cough, mild fever, and general tiredness. Viral sore throats resolve on their own within 5 to 7 days. Antibiotics do not help. This is where OTC throat lozenges shine — they provide symptomatic relief while your immune system does the heavy lifting.
Bacterial sore throats (strep throat)
About 15-30% of sore throats in children and 5-15% in adults are caused by Group A Streptococcus bacteria — commonly called strep throat. Signs that suggest bacterial infection include a sudden onset of severe throat pain, high fever (above 38.5 degrees Celsius), swollen and tender lymph nodes in the neck, white patches on the tonsils, and absence of cough or runny nose. Strep throat requires a GP visit and usually a course of antibiotics to prevent complications. Lozenges can help with pain while you wait for the antibiotics to kick in.
When to See Your GP
See your GP promptly if: your sore throat lasts longer than 7 days; you have a high fever (above 38.5°C); you notice white patches or pus on your tonsils; you have difficulty breathing or swallowing saliva; you experience a stiff neck or difficulty opening your mouth; a child under 4 has a persistent sore throat. These may be signs of a bacterial infection or another condition requiring professional assessment.
Other causes
- •Dry air or air conditioning: Common in Australian offices and during winter. Non-medicated lozenges and staying hydrated usually suffice.
- •Post-nasal drip: Mucus from allergies or sinusitis dripping down the back of the throat can cause irritation. Treating the underlying cause (with antihistamines or nasal sprays) is more effective than lozenges alone.
- •Voice strain: Teachers, coaches, and singers are prone to this. Rest your voice and use soothing lozenges.
- •Acid reflux (GORD): Stomach acid irritating the throat. Requires treatment of the reflux itself — lozenges provide only temporary relief.
What to Look For When Buying Throat Lozenges
- •Check the active ingredient: If you want genuine pain relief, look for benzydamine (Difflam), flurbiprofen (Strepsils Intensive), or an anaesthetic agent. If you just want comfort, menthol-based options are cheaper and effective.
- •Consider sugar content: If you are using multiple lozenges daily for several days, sugar-free options are better for your teeth. Strepsils and Difflam both offer sugar-free variants.
- •Read the age restrictions: Most medicated lozenges are not suitable for children under 6. Always check the label.
- •Look at pack size for value: Larger packs generally offer better value per lozenge. A 36-pack of Strepsils is usually better value than two 16-packs.
- •Check for drug interactions: If you take regular medications, particularly blood thinners or other NSAIDs, speak to your pharmacist before using anti-inflammatory lozenges.
Frequently Asked Questions
Are throat lozenges better than throat spray?
Neither is inherently better — they deliver active ingredients differently. Lozenges dissolve slowly and provide sustained contact with the throat over several minutes. Sprays deliver a quick burst of medication. Some people find sprays easier to use, especially children who might chew lozenges. Difflam, for example, is available as both a lozenge and a spray with the same active ingredient (benzydamine). The best choice comes down to personal preference.
How many throat lozenges can I take per day?
This varies by product and you should always follow the directions on the label. As a general guide: Difflam lozenges are typically limited to one every 1.5 to 3 hours (up to 12 per day for adults); Strepsils Original allow one every 2 to 3 hours; Strepsils Intensive is limited to a maximum of 5 lozenges in 24 hours. Non-medicated options like Soothers and Butter-Menthol do not have strict limits, but excessive use adds unnecessary sugar to your diet.
Can I give throat lozenges to children?
Most medicated lozenges are not recommended for children under 6 due to both the active ingredients and the choking risk. Some products, like Strepsils, have specific children's formulations suitable from age 6. For younger children, consult your pharmacist about age-appropriate options — honey (for children over 12 months) mixed with warm water is a well-supported home remedy. Never give lozenges to children under 3 due to the choking hazard.
Are throat lozenges safe during pregnancy?
Non-medicated lozenges like Soothers and Butter-Menthol are generally considered safe during pregnancy. However, medicated lozenges — particularly those containing NSAIDs like flurbiprofen (Strepsils Intensive) or benzydamine (Difflam) — should be used with caution. NSAIDs are generally avoided in the third trimester. Always consult your pharmacist or GP before using any medicated throat lozenge during pregnancy or breastfeeding.
Do throat lozenges actually kill germs?
Antiseptic lozenges like Strepsils Original do have demonstrated antibacterial and antiviral activity in laboratory settings. However, in practice, their ability to meaningfully reduce the duration or severity of infection is limited. The soothing effect of the lozenge itself — stimulating saliva and coating the throat — may provide as much benefit as the antiseptic action. Anti-inflammatory lozenges (Difflam, Strepsils Intensive) do not claim to kill germs but are typically more effective at reducing actual pain.
Can I use throat lozenges with paracetamol or ibuprofen?
Antiseptic lozenges (Strepsils Original) and non-medicated lozenges (Soothers, Butter-Menthol) can generally be used safely alongside oral pain relievers. However, be cautious combining anti-inflammatory lozenges (Difflam, Strepsils Intensive) with oral NSAIDs like ibuprofen (Nurofen), as this doubles up on the same type of drug and may increase the risk of stomach irritation. When in doubt, ask your pharmacist.
