What Are Sugar Free Cough Drops and Do They Work?

 

A scratchy throat and persistent cough can make even an ordinary day feel exhausting. Covonia Double Impact Cough Drops – Strong Original Sugar Free – 30g are an over-the-counter throat lozenge designed to soothe irritation and ease coughing without any added sugar. If you are looking for sugar free cough drops that deliver a genuinely cooling sensation, these are worth considering. They are available to buy from our Ear, Nose & Throat range at Cured Pharmacy.

Coughs are one of the most common reasons people visit a pharmacist in the UK. The NHS notes that most coughs are caused by viral upper respiratory tract infections and typically resolve within three weeks. Throat lozenges containing menthol can help manage symptoms in the meantime, providing temporary relief while your body recovers naturally.

 

How Do Covonia Double Impact Cough Drops Work?

 

The "double impact" name refers to the two-pronged approach these drops take. They combine menthol and eucalyptus oil — both well-established ingredients in cough and throat products — to target irritation from two angles simultaneously.

  • Menthol activates cold-sensitive receptors (TRPM8 receptors) in the mouth and throat, creating a cooling sensation that temporarily reduces the perception of throat irritation and the urge to cough.
  • Eucalyptus oil has mild decongestant properties and contributes an additional soothing effect on the upper airways.
  • Dissolving slowly in the mouth allows the active ingredients to coat the throat lining gradually, prolonging the soothing effect.
  • The sugar free formulation means the drops do not contribute to tooth decay, which is a genuine advantage over sugar-containing alternatives.

 

Who Should Use Covonia Double Impact Cough Drops?

 

These drops are suitable for adults and young people aged 12 and over who are experiencing a dry, tickly, or irritating cough, or a sore throat associated with a cold or mild upper respiratory infection. They are particularly useful for anyone who wants to avoid added sugar in their throat remedies.

  • Adults with a dry or tickly cough linked to a cold or mild throat irritation
  • People with diabetes or those monitoring their sugar intake who still need cough relief
  • Individuals who prefer a menthol-based lozenge over liquid cough medicines
  • Anyone aged 12 and over looking for a convenient, portable cough remedy

They are not intended to treat productive (chesty) coughs where mucus is present, or coughs caused by smoking, asthma, or other underlying conditions. If you are unsure whether these drops are right for you, speak to a pharmacist before use.

 

How Do Covonia Cough Drops Compare to Other Throat Lozenges?

 

Feature Covonia Double Impact Sugar Free Standard Sugar-Containing Throat Lozenge
Sugar free Yes No
Active ingredients Menthol & Eucalyptus Oil Varies (often menthol only)
Suitable for diabetics More suitable Less suitable
Cooling sensation Strong (double action) Mild to moderate

 

Are Covonia Sugar Free Cough Drops Safe to Store and Use Long Term?

 

These drops should be stored below 25°C in a dry place, away from direct sunlight. Keep them out of reach of children. Once opened, use within the period indicated on the packaging. If you are managing other health conditions alongside a cough — for example, if you also need support from our Cold and Flu collection — it is worth reviewing all products with your pharmacist to avoid any overlap in ingredients.

These are intended for short-term symptomatic relief only. If your cough persists beyond seven days, worsens, or is accompanied by a high fever, breathlessness, or blood in phlegm, you should seek medical advice promptly. Do not use these drops as a substitute for medical treatment of an underlying condition.

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 Covonia Double Impact Cough Drops and What Are They Used For?

 

Covonia Double Impact Cough Drops – Strong Original Sugar Free are an over-the-counter throat lozenge used to relieve the symptoms of a dry, tickly, or irritating cough and sore throat. They contain menthol and eucalyptus oil, both of which have a long history of use in cough and throat preparations. The NHS advises that most coughs caused by colds or mild upper respiratory infections do not require prescription treatment and can be managed with self-care measures, including throat lozenges. These drops are classified as a General Sale List (GSL) medicine in the UK, meaning you can purchase them without a prescription.

 

What Do You Need to Know Before Using Covonia Double Impact Cough Drops?

 

Before using these drops, read the following carefully. They are not suitable for everyone.

Do not use these drops if you:

  • Are under 12 years of age
  • Are allergic to menthol, eucalyptus oil, or any other ingredient in the product
  • Have a productive (chesty) cough with significant mucus — a different product may be more appropriate
  • Have a cough caused by asthma, chronic bronchitis, or emphysema without first consulting a doctor

Speak to your pharmacist or GP before use if you:

  • Are pregnant or breastfeeding
  • Have diabetes — while these drops are sugar free, some sweeteners used may still affect some individuals
  • Are taking any prescribed medicines
  • Have a persistent cough lasting more than seven days

Known interactions:

  • No significant drug interactions are known at standard doses for menthol or eucalyptus oil lozenges
  • If you are taking multiple medicines, always check with your pharmacist

 

How Should You Use Covonia Double Impact Cough Drops?

 

Using these drops correctly ensures you get the most benefit from them. Always follow the instructions on the packaging. Do not chew or swallow the drops whole — they are designed to dissolve slowly.

  1. Wash your hands before handling the drops.
  2. Place one drop in your mouth.
  3. Allow it to dissolve slowly — do not chew or crunch it.
  4. Repeat as needed, following the dosage guidance below.

If you are also dealing with other cold symptoms, you might find it helpful to browse our Cold and Flu range for complementary products.

 

What Are the Possible Side Effects of Covonia Double Impact Cough Drops?

 

Like all medicines, these drops can cause side effects, although not everyone experiences them. Menthol and eucalyptus oil are generally well tolerated at the doses found in throat lozenges.

Common side effects:

  • Mild tingling or cooling sensation in the mouth and throat (this is expected and part of the product's action)
  • Temporary mild mouth irritation

Less common side effects:

  • Nausea if drops are used excessively or swallowed whole
  • Allergic reactions — including rash, itching, or swelling — are rare but possible; stop use immediately if these occur
  • Heartburn or mild stomach discomfort in sensitive individuals

If you experience any serious reaction, including difficulty breathing or swelling of the face or throat, seek emergency medical attention immediately. The NHS advises contacting 999 or going to A&E for signs of a severe allergic reaction (anaphylaxis).

 

How Should You Store Covonia Double Impact Cough Drops?

 

Proper storage keeps the drops effective and safe to use throughout their shelf life. If you are keeping a range of health products at home — including items from our Pain Relief collection — it is good practice to store all medicines together in a cool, dry place out of children's reach.

  • Store below 25°C
  • Keep in a dry place, away from direct sunlight and moisture
  • Keep out of the sight and reach of children
  • Do not use after the expiry date printed on the packaging
  • Do not store in a bathroom cabinet where humidity can affect the product

Frequently Asked Questions

Where can I buy Covonia Double Impact Sugar Free Cough Drops online in the UK?

You can buy Covonia Double Impact Sugar Free Cough Drops directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. They are available without a prescription as a General Sale List medicine. Simply add them to your basket and they will be dispatched to your door.

How do Covonia Double Impact Cough Drops work in the body?

The drops contain menthol, which activates cold-sensitive TRPM8 receptors in the mouth and throat, producing a cooling sensation that temporarily reduces the urge to cough. Eucalyptus oil adds a secondary soothing effect on the upper airways. Together, they provide a dual-action approach to throat and cough irritation.

Are Covonia sugar free cough drops suitable for people with diabetes?

Yes, these drops are sugar free, which makes them a more appropriate choice for people with diabetes compared to sugar-containing throat sweets. However, they do contain sweeteners, so if you have any concerns about specific ingredients, check with your pharmacist or diabetes care team before use.

How do I use Covonia Double Impact Cough Drops step by step?

Place one drop in your mouth and allow it to dissolve slowly — do not chew or swallow it whole. Repeat as needed according to the dosage instructions on the pack. Dissolving the drop slowly ensures the menthol and eucalyptus oil coat the throat lining for maximum soothing effect.

What is the correct dose of Covonia cough drops for adults?

Adults and young people aged 12 and over should dissolve one drop slowly in the mouth as needed. Always follow the dosage instructions printed on the packaging and do not exceed the recommended daily amount. If you are unsure, ask your pharmacist for guidance.

Can children under 12 use Covonia Double Impact Sugar Free Cough Drops?

No — these drops are not recommended for children under 12 years of age. If you need cough or throat relief for a younger child, speak to a pharmacist who can recommend a suitable age-appropriate product. You can also browse our Baby and Toddler range for products designed for younger children.

What are the side effects of Covonia sugar free cough drops?

Side effects are uncommon at normal doses. You may notice a mild tingling or cooling sensation in the mouth, which is expected. Rarely, some people may experience mild mouth irritation or, if drops are overused, nausea. Stop use and consult a pharmacist if you notice any unusual reaction.

How long can I use Covonia cough drops for?

These drops are intended for short-term symptomatic relief only. If your cough or sore throat has not improved after seven days, or if it worsens, you should seek advice from a pharmacist or GP. Persistent coughs can sometimes indicate an underlying condition that needs proper assessment.

Are Covonia Double Impact Cough Drops sugar free and vegan?

These drops are confirmed as sugar free. For specific information about vegan suitability, check the product packaging or contact the manufacturer directly, as formulations can change. If you are looking for vegan-friendly health products more broadly, our Vegan collection may be helpful.

What are alternatives to Covonia sugar free cough drops?

Alternatives include other menthol-based throat lozenges, sugar free throat sweets from other brands, or liquid cough medicines containing similar active ingredients. Your pharmacist can help you choose the most appropriate option based on your specific symptoms and medical history.

Can I use Covonia cough drops during pregnancy?

If you are pregnant, you should speak to your GP or pharmacist before using any over-the-counter medicine, including throat lozenges. While menthol lozenges are widely used, there is limited formal clinical data on their safety in pregnancy, so professional guidance is always the safest approach.

Do Covonia cough drops interact with other medicines?

No significant drug interactions are known for menthol or eucalyptus oil lozenges at standard doses. However, if you are taking prescribed medicines or have an underlying health condition, it is always sensible to check with your pharmacist before adding any new product to your routine.

What is the best time to use Covonia Double Impact Cough Drops?

You can use these drops at any time of day when you experience cough or throat irritation. Many people find them particularly helpful during the day when a tickly cough is most disruptive, or in the evening to ease throat discomfort before sleep. Use them as needed within the recommended daily dose.

What happens if I accidentally swallow a Covonia cough drop whole?

Swallowing a single drop whole is unlikely to cause serious harm in an adult, but it may cause mild nausea or stomach discomfort. The drops are designed to dissolve slowly in the mouth for maximum effect. If a child swallows one, or if you have any concerns, contact NHS 111 for advice.

What are the latest findings on menthol lozenges for cough relief?

Menthol has been studied for its action on TRPM8 cold receptors, and research supports its role in temporarily reducing cough sensitivity and throat irritation. The NHS and BNF both recognise demulcent lozenges as a reasonable self-care option for dry, tickly coughs. These drops align with current evidence-based self-care guidance for mild upper respiratory symptoms.

How Should You Use Covonia Double Impact Sugar Free Cough Drops?

These drops are designed to be dissolved slowly in the mouth — not chewed or swallowed whole. Allowing them to dissolve gradually ensures the menthol and eucalyptus oil coat the throat lining properly, giving you the most effective relief from irritation and coughing.

Follow these steps each time you use a drop:

What Is the Correct Dose of Covonia Double Impact Sugar Free Cough Drops?

Always follow the dosage instructions printed on the product packaging. The table below summarises the general guidance for this product.

Never exceed the recommended daily dose. If you are unsure how many drops are appropriate for your situation, ask your pharmacist before use.

When Is the Best Time to Use Covonia Double Impact Sugar Free Cough Drops?

You can use these drops at any point during the day when coughing or throat irritation becomes uncomfortable. Many people find them most useful during the daytime when a persistent tickly cough is disruptive to work or conversation. They can also be helpful in the evening to ease throat discomfort before sleep, though they are not a sedative and will not directly aid sleep.

There is no fixed schedule — use them as and when symptoms arise, within the daily dose limit. If you find yourself needing them very frequently throughout the day, that may be a sign your symptoms need further assessment by a pharmacist or GP.

How Long Can You Use Covonia Double Impact Sugar Free Cough Drops For?

These drops are intended for short-term use only. Most coughs caused by a cold or mild upper respiratory infection resolve within two to three weeks, and the drops are designed to manage symptoms during that period. If your cough or sore throat has not improved after seven days of use, or if it gets worse rather than better, stop using the drops and seek advice from a pharmacist or GP.

Do not use these drops as a long-term solution for a chronic cough. Persistent coughing can be a sign of an underlying condition — such as asthma, acid reflux, or a more serious respiratory issue — that requires proper diagnosis and treatment.

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

What Are the Most Common Side Effects of Covonia Double Impact Sugar Free Cough Drops?

Most people use these drops without experiencing any unwanted effects. The most frequently noticed sensation is the strong cooling feeling in the mouth and throat — this is entirely expected and is part of how the menthol works. It is not a side effect in the traditional sense, but if you find it unexpectedly intense, simply allow the drop to dissolve more slowly.

  • Strong cooling or tingling sensation in the mouth and throat
  • Mild temporary mouth irritation
  • Slight watering of the eyes due to the menthol vapour

What Are the Less Common Side Effects of Covonia Double Impact Sugar Free Cough Drops?

Less commonly, some people may experience mild digestive discomfort, particularly if drops are used more frequently than recommended or swallowed whole rather than dissolved slowly. These effects are generally mild and resolve on their own once you stop using the product.

  • Nausea or mild stomach discomfort, particularly if overused
  • Heartburn or acid reflux in sensitive individuals
  • Mild headache in rare cases

What Are the Serious Side Effects of Covonia Double Impact Sugar Free Cough Drops?

Serious side effects are rare but can occur. Allergic reactions to menthol or eucalyptus oil, while uncommon, have been reported. Signs of a serious allergic reaction include swelling of the face, lips, tongue, or throat, difficulty breathing, a sudden rash, or dizziness. If you experience any of these symptoms, stop using the drops immediately and seek emergency medical attention by calling 999 or going to your nearest A&E department.

Do not ignore symptoms that feel unusual or disproportionate to what you would expect from a throat lozenge. When in doubt, always seek professional advice.

What Should You Do If You Experience Side Effects of Covonia Cough Drops?

For mild side effects such as mouth irritation or nausea, simply stop using the drops and allow the symptoms to settle. Drinking water can help. If the side effect is more persistent or concerning, contact your pharmacist or GP for guidance. You can also report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk — this helps improve medicine safety for everyone.

Can Covonia Double Impact Cough Drops Interact With Other Medicines?

No clinically significant drug interactions are currently known for menthol or eucalyptus oil lozenges used at standard doses. However, if you are taking prescribed medicines — particularly those for respiratory conditions, heart conditions, or epilepsy — it is always worth checking with your pharmacist before using any new over-the-counter product. This is especially important if you are already using other cough or cold remedies that may contain overlapping ingredients.

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