What Are Sore Throat Lozenges and How Do Strefen Honey & Lemon Lozenges Help?

 

A sore throat can stop you in your tracks. Whether it's that scratchy, raw feeling first thing in the morning or a sharp pain every time you swallow, throat discomfort is one of the most common reasons people visit a pharmacist. Sore throat lozenges like Strefen Honey & Lemon offer a targeted, locally acting option that gets to work right where it hurts. Each lozenge contains flurbiprofen 8.75mg — a non-steroidal anti-inflammatory drug (NSAID) — which tackles both the pain and the underlying inflammation causing it. You can browse our full range of ear, nose and throat remedies if you're looking for additional support alongside these lozenges.

Strefen Honey & Lemon Lozenges are available over the counter for adults and adolescents aged 12 and over. The honey and lemon flavour makes them pleasant to use, which matters when you're already feeling rough. Each pack contains 16 lozenges, giving you a solid course of treatment to get through the worst of a sore throat episode.

 

How Do Strefen Honey & Lemon Lozenges Work?

 

Flurbiprofen, the active ingredient in Strefen, belongs to the NSAID class of medicines. NSAIDs work by inhibiting the enzyme cyclo-oxygenase (COX), which is responsible for producing prostaglandins — the chemical messengers that trigger pain and inflammation in the body. By reducing prostaglandin production locally in the throat, flurbiprofen helps ease both the pain and swelling that make swallowing so uncomfortable.

  • The lozenge dissolves slowly in the mouth, releasing flurbiprofen directly onto the throat mucosa.
  • Local delivery means the active ingredient reaches the inflamed tissue quickly and efficiently.
  • Anti-inflammatory action reduces swelling in the throat lining, not just masking pain.
  • Each lozenge provides relief for up to 3 to 6 hours per dose.

 

Who Should Use Strefen Honey & Lemon Lozenges?

 

These lozenges are designed for adults and adolescents aged 12 and over who are experiencing a sore throat with associated pain and inflammation. They're particularly useful when your throat feels inflamed rather than just mildly irritated — for example, during a cold, flu, or tonsillitis episode. That said, they're not a substitute for antibiotics if a bacterial infection is confirmed by your GP.

  • Adults aged 18 and over with acute sore throat pain
  • Adolescents aged 12 to 17 (under adult supervision)
  • People who prefer a locally acting treatment over systemic oral tablets
  • Those who want anti-inflammatory action alongside pain relief

 

How Do Strefen Lozenges Compare to Other Sore Throat Remedies?

Are Strefen Lozenges Suitable for Everyone, and How Should They Be Stored?

 

Not everyone can use Strefen lozenges safely. They are not suitable for children under 12, people with a known hypersensitivity to aspirin or other NSAIDs, those with active peptic ulcers, or individuals with severe kidney, liver, or heart failure. If you are pregnant or breastfeeding, speak to your doctor or pharmacist before using these lozenges, as NSAIDs carry specific risks during pregnancy — particularly in the third trimester. If you're managing other health conditions alongside a sore throat, our cold and flu range may also be worth exploring for complementary symptom relief.

Store Strefen Honey & Lemon Lozenges below 25°C in a dry place, away from direct sunlight. Keep them out of the reach and sight of children. Do not use after the expiry date printed on the packaging.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Are Strefen Honey & Lemon Lozenges and What Are They Used For?

 

Strefen Honey & Lemon Lozenges are an over-the-counter medicine used to relieve the pain and inflammation of sore throats in adults and adolescents aged 12 and over. Each lozenge contains flurbiprofen 8.75mg, an NSAID that acts locally in the throat to reduce both pain and swelling. According to the NHS, most sore throats are caused by viral infections and will clear up on their own within a week, but medicines like these lozenges can help manage symptoms in the meantime. They are not intended to treat the underlying cause of a sore throat — they simply make the experience more bearable while your body recovers.

 

What Do You Need to Know Before Using Strefen Honey & Lemon Lozenges?

 

Before using these lozenges, it's important to check whether they are appropriate for you. Do not use Strefen Honey & Lemon Lozenges if any of the following apply:

  • You are under 12 years of age
  • You have a known allergy or hypersensitivity to flurbiprofen, aspirin, or any other NSAID
  • You have or have had a peptic ulcer or gastrointestinal bleeding
  • You have severe heart failure, severe kidney impairment, or severe liver impairment
  • You are in the third trimester of pregnancy
  • You have been told to avoid NSAIDs by your doctor

The following medicines may interact with flurbiprofen. Tell your pharmacist or doctor if you are taking any of these:

  • Anticoagulants such as warfarin or heparin
  • Other NSAIDs including ibuprofen or aspirin
  • Lithium
  • Methotrexate
  • Antihypertensive medicines (blood pressure treatments)
  • Diuretics (water tablets)

 

How Should You Use Strefen Honey & Lemon Lozenges?

 

Always use these lozenges exactly as described in the patient information leaflet or as directed by your pharmacist. Do not chew or swallow the lozenge whole — it needs to dissolve slowly in your mouth to deliver the active ingredient to the throat.

  1. Place one lozenge in your mouth.
  2. Allow it to dissolve slowly — do not chew or bite it.
  3. Repeat every 3 to 6 hours as needed.
  4. Do not use more than 5 lozenges in any 24-hour period.
  5. Do not use for more than 3 consecutive days without consulting a doctor or pharmacist.
Indication Age Group Dose Frequency
Sore throat pain and inflammation Adults (18+) 1 lozenge Every 3–6 hours, max 5 in 24 hours
Sore throat pain and inflammation Adolescents (12–17) 1 lozenge Every 3–6 hours, max 5 in 24 hours
Not applicable Children under 12 Do not use Not recommended

If you're also dealing with other cold and flu symptoms alongside your sore throat, you might find it helpful to explore our pain relief range for additional options to manage headaches or body aches at the same time.

 

What Are the Possible Side Effects of Strefen Honey & Lemon Lozenges?

 

Like all medicines, Strefen lozenges can cause side effects, although not everyone will experience them. If you notice any side effects that concern you, stop using the lozenges and speak to your pharmacist or GP.

Common side effects (may affect up to 1 in 10 people):

  • Mouth or throat irritation
  • Nausea
  • Oral discomfort or altered taste

Less common side effects (may affect up to 1 in 100 people):

  • Headache
  • Dizziness
  • Gastrointestinal discomfort or upset stomach
  • Mouth ulcers

Seek immediate medical attention if you experience swelling of the face, lips, tongue, or throat, difficulty breathing, or a severe skin reaction. These may be signs of a serious allergic reaction (anaphylaxis), which is rare but requires urgent treatment.

 

How Should You Store Strefen Honey & Lemon Lozenges?

 

Correct storage helps maintain the quality and safety of your lozenges. Follow these guidelines:

  • Store below 25°C in a dry place
  • Keep away from direct sunlight and moisture
  • Keep out of the reach and sight of children
  • Do not use after the expiry date printed on the packaging
  • Do not dispose of medicines via wastewater or household waste — return unused lozenges to your pharmacist

If you're looking after your general health during a bout of illness, it's also worth checking whether your vitamins and supplements are supporting your immune system through recovery.

Frequently Asked Questions

Where can I buy Strefen Honey & Lemon Lozenges online in the UK?

You can buy Strefen Honey & Lemon Lozenges directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, without a prescription. They are classed as an over-the-counter medicine suitable for adults and adolescents aged 12 and over. Simply add them to your basket and they'll be dispatched promptly to your door.

How do Strefen Honey & Lemon Lozenges work in the body?

Strefen lozenges contain flurbiprofen 8.75mg, an NSAID that inhibits the cyclo-oxygenase (COX) enzyme, reducing the production of prostaglandins — the chemicals responsible for pain and inflammation. Because the lozenge dissolves slowly in the mouth, flurbiprofen is delivered directly to the inflamed throat tissue rather than being absorbed systemically first. This local action means you can feel relief relatively quickly at the site of discomfort.

How do I use Strefen Honey & Lemon Lozenges step by step?

Place one lozenge in your mouth and allow it to dissolve slowly — do not chew or swallow it whole. You can use one lozenge every 3 to 6 hours as needed, up to a maximum of 5 lozenges in any 24-hour period. Do not use for more than 3 consecutive days without speaking to a pharmacist or doctor.

What is the maximum dose of Strefen lozenges in 24 hours?

The maximum dose is 5 lozenges in any 24-hour period for adults and adolescents aged 12 and over. Exceeding this dose increases the risk of side effects without providing additional benefit. If your symptoms are severe enough that you feel you need more than the recommended amount, please consult your GP or pharmacist.

When is the best time to use Strefen Honey & Lemon Lozenges?

Use a lozenge whenever your sore throat pain is most troublesome — many people find mornings and evenings particularly uncomfortable. Space each lozenge at least 3 hours apart and try to use them at consistent intervals throughout the day for steady symptom control. Avoid using them immediately before bed if you're concerned about the lozenge dissolving while you're drowsy.

What are the side effects of Strefen Honey & Lemon Lozenges?

Common side effects include mouth or throat irritation, nausea, and altered taste. Less commonly, some people experience headache, dizziness, or mild gastrointestinal discomfort. Rarely, a serious allergic reaction can occur — if you notice swelling of the face, lips, or throat, or have difficulty breathing, seek emergency medical help immediately.

How do I manage side effects from Strefen lozenges?

If you experience mild mouth or throat irritation, try allowing the lozenge to dissolve more slowly or use it after eating. For nausea, using the lozenge with a small amount of food or water beforehand may help. If side effects persist or feel severe, stop using the lozenges and speak to your pharmacist or GP promptly.

Who should not use Strefen Honey & Lemon Lozenges?

These lozenges are not suitable for children under 12, people with a known allergy to aspirin or other NSAIDs, those with active peptic ulcers, or individuals with severe heart, kidney, or liver failure. They should also be avoided in the third trimester of pregnancy. Always check with your pharmacist if you are unsure whether this product is right for you — you can also browse our ear, nose and throat range for alternative options.

Can I take Strefen lozenges if I am pregnant or breastfeeding?

Strefen lozenges should not be used during the third trimester of pregnancy, as NSAIDs can cause harm to the unborn baby at this stage. Use during the first and second trimesters should only be considered on the advice of a doctor. If you are breastfeeding, speak to your pharmacist or GP before using these lozenges, as flurbiprofen may pass into breast milk.

Can I take Strefen lozenges with other medicines?

Strefen lozenges can interact with several medicines, including anticoagulants like warfarin, other NSAIDs such as ibuprofen or aspirin, lithium, methotrexate, blood pressure medicines, and diuretics. Always tell your pharmacist about every medicine you are currently taking before starting Strefen lozenges. If you are taking any of these medicines, your pharmacist can advise on the safest approach.

What happens if I miss a dose of Strefen lozenges?

If you forget to take a lozenge when your symptoms flare up, simply use one as soon as you remember — as long as it has been at least 3 hours since your last lozenge. Do not double up by taking two lozenges at once to make up for a missed dose. Continue with your usual schedule and stay within the maximum of 5 lozenges per 24 hours.

How long can you use Strefen Honey & Lemon Lozenges for?

Strefen lozenges should not be used for more than 3 consecutive days. Most viral sore throats begin to improve within this timeframe. If your symptoms have not improved after 3 days, or if they worsen at any point, you should consult your GP to rule out a bacterial infection or another underlying cause.

Are Strefen lozenges the same as sore throat lozenges containing anaesthetic?

No — Strefen lozenges work differently from anaesthetic lozenges. Anaesthetic lozenges (such as those containing lidocaine) temporarily numb the throat to mask pain, whereas Strefen contains flurbiprofen, an NSAID that actively reduces inflammation as well as pain. This means Strefen addresses one of the root causes of throat discomfort rather than simply numbing the sensation.

What are the alternatives to Strefen Honey & Lemon Lozenges?

Alternatives include anaesthetic lozenges containing lidocaine, antiseptic lozenges such as those containing amylmetacresol and dichlorobenzyl alcohol, or systemic pain relief such as paracetamol or ibuprofen tablets. The right choice depends on your symptoms and medical history — your pharmacist can help you decide. You can also explore our wider cold and flu collection for complementary products.

What does the latest research say about flurbiprofen lozenges for sore throat?

Clinical studies have shown that flurbiprofen 8.75mg lozenges provide statistically significant reductions in sore throat pain compared to placebo, with onset of action within approximately 30 minutes of use. Research published in peer-reviewed journals supports their use for acute pharyngitis and tonsillitis-related throat pain in adults. The NHS recognises NSAIDs as an effective option for managing sore throat discomfort while the body fights the underlying infection.

How Should You Use Strefen Honey & Lemon Lozenges?

Using Strefen Honey & Lemon Lozenges correctly is straightforward, but it's important to follow the instructions carefully to get the most benefit and avoid unnecessary side effects. The lozenge must dissolve slowly in your mouth — this is what allows the flurbiprofen to reach the inflamed throat tissue directly.

Follow these steps each time you use a lozenge:

What Is the Correct Dose of Strefen Honey & Lemon Lozenges?

The correct dose depends on your age. Do not exceed the recommended dose under any circumstances. If you are unsure whether this product is appropriate for you, speak to your pharmacist before use.

When Is the Best Time to Use Strefen Honey & Lemon Lozenges?

Use a lozenge whenever your sore throat pain is at its worst — many people find that symptoms are most intense in the morning upon waking or in the evening. Try to space each lozenge at least 3 hours apart to maintain consistent relief throughout the day without exceeding the maximum daily dose.

Avoid using a lozenge immediately before lying down or sleeping, as the lozenge needs to dissolve fully in an upright or seated position for safe and effective use.

How Long Can You Use Strefen Honey & Lemon Lozenges For?

Strefen Honey & Lemon Lozenges should not be used for more than 3 consecutive days. The NHS advises that most sore throats caused by viral infections resolve within 7 to 10 days, with the worst symptoms typically easing within the first few days.

If your sore throat has not improved after 3 days of using these lozenges, or if your symptoms worsen at any point, stop using the lozenges and consult your GP. This is particularly important if you develop a high fever, difficulty swallowing, or a rash, as these may indicate a more serious condition requiring medical assessment.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Strefen Honey & Lemon Lozenges?

Most people use Strefen Honey & Lemon Lozenges without experiencing significant side effects. However, as with all medicines containing an NSAID, some people do notice mild reactions, particularly in the mouth and throat where the lozenge dissolves.

  • Mouth or throat irritation
  • Nausea
  • Altered or unpleasant taste in the mouth
  • Oral discomfort

What Are the Less Common Side Effects of Strefen Honey & Lemon Lozenges?

Less commonly, some people may experience side effects that are more systemic in nature, even though the lozenge acts locally. These are generally mild and resolve once you stop using the lozenges.

  • Headache
  • Dizziness
  • Mild gastrointestinal discomfort or upset stomach
  • Mouth ulcers
  • Dry mouth

What Are the Serious Side Effects of Strefen Honey & Lemon Lozenges?

Serious side effects are rare but require immediate medical attention. Because flurbiprofen is an NSAID, there is a small risk of serious reactions, particularly in people who are sensitive to this class of medicine. Stop using the lozenges immediately and seek emergency help if you experience any of the following:

  • Swelling of the face, lips, tongue, or throat (angioedema)
  • Difficulty breathing or wheezing
  • Severe skin reactions such as blistering or peeling
  • Signs of gastrointestinal bleeding, such as vomiting blood or passing black stools

What Should You Do If You Experience Side Effects of Strefen Lozenges?

For mild side effects such as mouth irritation or nausea, try allowing the lozenge to dissolve more slowly or use it after a small meal. If side effects are persistent, uncomfortable, or worrying, stop using the lozenges and speak to your pharmacist or GP as soon as possible. You can also report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Never ignore a side effect that feels unusual or severe. Your pharmacist is always a good first point of contact for advice on managing any reactions you experience.

Can Strefen Honey & Lemon Lozenges Interact With Other Medicines?

Yes — because flurbiprofen is an NSAID, it can interact with a number of other medicines. These interactions can increase the risk of side effects or reduce the effectiveness of other treatments you may be taking. Always inform your pharmacist or doctor about every medicine, supplement, or herbal remedy you are currently using before starting Strefen lozenges.

Key interactions to be aware of include anticoagulants such as warfarin (increased bleeding risk), other NSAIDs or aspirin (increased gastrointestinal side effects), lithium (increased lithium levels in the blood), methotrexate (increased toxicity risk), antihypertensives (reduced blood pressure control), and diuretics (reduced effectiveness and increased kidney risk).

If you are concerned about any side effects, contact your pharmacist or GP immediately.
