What Are Menthol Pastilles for Colds?

 

When a cold strikes, the combination of a scratchy throat and a stuffy nose can make even the simplest tasks feel exhausting. Menthol pastilles for colds offer a convenient, no-fuss way to ease those symptoms while you go about your day. Olbas Oil Menthol Pastilles bring together the familiar cooling sensation of menthol with the classic Olbas Oil aromatic blend — a combination that has been trusted in UK households for decades. If you're looking for other cold and flu remedies to complement your recovery, you can browse our full cold and flu range at Cured Pharmacy.

Each pastille is designed to dissolve slowly in the mouth, releasing active aromatic vapours that work on both the throat and the nasal passages simultaneously. They're small enough to carry in a pocket or bag, which makes them genuinely practical when you're at work or out and about.

 

How Do Olbas Oil Menthol Pastilles Work?

 

The mechanism here is straightforward but effective. As the pastille dissolves on your tongue, it releases a blend of volatile aromatic oils alongside menthol. These compounds stimulate cold-sensitive receptors in the mouth and throat — particularly TRPM8 receptors — producing that characteristic cooling sensation. At the same time, the vapours travel upward into the nasal cavity, helping to temporarily relieve the feeling of congestion.

  • Menthol activates cold receptors in the mucous membranes, reducing the perception of nasal blockage
  • Eucalyptus oil has mild decongestant properties and contributes to the soothing vapour effect
  • Mint and cajeput oils add to the cooling, refreshing sensation in the throat
  • Wintergreen and clove oils provide a mild analgesic-like warmth that can ease throat discomfort

It's worth noting that these pastilles don't treat the underlying viral infection — colds are caused by viruses and resolve on their own. What they do is make the symptomatic period more manageable.

 

Who Should Use Olbas Oil Menthol Pastilles?

 

These pastilles are suitable for most adults and older children dealing with the typical symptoms of a cold or mild upper respiratory tract infection. They're particularly useful if you want symptom relief without reaching for a liquid medicine or tablet.

  • Adults and teenagers aged 12 and over experiencing sore throat or nasal congestion
  • People who prefer a lozenge format over syrups or sprays
  • Those looking for a non-drowsy option that won't interfere with driving or work
  • Individuals who want to complement other cold remedies already in use

They are not suitable for children under 3 years of age. If you're unsure whether they're right for a child between 3 and 12, speak to a pharmacist first.

 

How Do Olbas Oil Menthol Pastilles Compare to Other Cold Lozenges?

 

Feature Olbas Oil Menthol Pastilles Standard Menthol Lozenges
Active ingredients Menthol + Olbas Oil aromatic blend Menthol only (typically)
Nasal congestion relief Yes — aromatic vapours target nasal passages Limited — menthol sensation only
Throat soothing Yes Yes
Suitable for children under 3 No Varies by product

 

Are Olbas Oil Menthol Pastilles Suitable for Everyday Storage and Use?

 

Store your pastilles below 25°C in a dry place, away from direct sunlight. Avoid leaving them in a hot car or on a sunny windowsill, as heat can cause the pastilles to soften and stick together. Once opened, keep the pack sealed to preserve the aromatic oils. These menthol pastilles for colds are a handy addition to any medicine cabinet during the winter months, and they travel well in a bag or coat pocket. If you're stocking up on other throat and respiratory products, our ear, nose and throat collection has a wide selection to choose from.

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.

Specifications of Olbas Oil Menthol Pastilles

 

What Are Olbas Oil Menthol Pastilles and What Are They Used For?

 

Olbas Oil Menthol Pastilles are an over-the-counter (OTC) remedy used to relieve the symptoms of colds, catarrh, and mild upper respiratory tract infections. They work by releasing menthol and a blend of aromatic plant-derived oils as they dissolve in the mouth, providing temporary relief from sore throats and the sensation of nasal congestion. They do not treat the underlying viral cause of a cold — the NHS advises that most colds clear up on their own within 7 to 10 days — but they can make the symptomatic period considerably more comfortable.

These pastilles are classified as a General Sale List (GSL) medicine in the UK, meaning you can purchase them without a prescription. They are not an antibiotic and will not shorten the duration of a viral illness.

 

What Do You Need to Know Before Using Olbas Oil Menthol Pastilles?

 

Before using these pastilles, check the following contraindications and warnings carefully:

  • Do not use if you are allergic to menthol, eucalyptus oil, mint oil, cajeput oil, wintergreen oil, juniper berry oil, clove oil, or any other ingredient in the pastille
  • Not suitable for children under 3 years of age
  • Speak to your GP or pharmacist before use if you are pregnant or breastfeeding — some aromatic oils are not recommended during pregnancy
  • Avoid use if you have a known sensitivity to salicylates (wintergreen oil contains methyl salicylate)
  • If your sore throat is severe, persists for more than 3 days, or is accompanied by a high fever, difficulty swallowing, or a rash, seek medical advice rather than self-treating

Regarding drug interactions, no clinically significant interactions have been reported at standard OTC doses. However:

  • Wintergreen oil (methyl salicylate) may theoretically interact with anticoagulants such as warfarin if used in large quantities — this is more relevant to topical products but worth noting
  • If you are taking any prescribed medicines, check with your pharmacist before use

 

How Should You Use Olbas Oil Menthol Pastilles?

 

  1. Remove one pastille from the pack
  2. Place it in your mouth and allow it to dissolve slowly — do not chew or swallow whole
  3. Breathe gently through your nose as it dissolves to maximise the decongestant vapour effect
  4. Repeat as needed, following the maximum daily dose on the packaging
  5. Wash your hands after handling if you have been touching your face or nose
Age Group Dose Frequency
Adults and children 12+ 1 pastille As needed; do not exceed stated daily maximum
Children 3–11 As directed on pack (age-appropriate dose) As needed; consult pharmacist if unsure
Children under 3 Not suitable

What Are the Possible Side Effects of Olbas Oil Menthol Pastilles?

 

Side effects with these pastilles are uncommon when used as directed. Most people tolerate them well. However, as with any medicine, reactions can occur.

Common side effects:

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

Less common side effects:

  • Mild mouth or throat irritation, particularly with prolonged or excessive use
  • Nausea if too many pastilles are taken in a short period
  • Allergic reactions (rare) — symptoms may include rash, itching, swelling of the mouth or throat, or difficulty breathing; seek immediate medical attention if this occurs

Stop using the pastilles and speak to a pharmacist or GP if you experience any unexpected or worsening symptoms.

 

How Should You Store Olbas Oil Menthol Pastilles?

 

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and sources of heat
  • Keep the pack sealed when not in use to preserve the aromatic oils
  • 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 or near a sink where moisture could affect the pastilles

How do Olbas Oil Menthol Pastilles work in the body?

As the pastille dissolves in your mouth, it releases menthol and a blend of aromatic oils including eucalyptus, mint, and cajeput. These compounds stimulate cold-sensitive receptors in the mouth and throat, creating a cooling sensation that eases discomfort. The vapours also travel into the nasal passages, temporarily relieving the feeling of congestion.

How do I use Olbas Oil Menthol Pastilles step by step?

Place one pastille in your mouth and allow it to dissolve slowly — do not chew or swallow it whole. Breathe gently through your nose as it dissolves to get the most from the decongestant vapours. Repeat as needed throughout the day, staying within the maximum daily dose stated on the pack.

What is the correct dose of Olbas Oil Menthol Pastilles for adults?

Adults and children aged 12 and over should take one pastille as needed, without exceeding the maximum daily dose printed on the packaging. If symptoms persist beyond 3 days or worsen, speak to a pharmacist or GP. Do not take more than the recommended amount in an attempt to speed up relief.

Are Olbas Oil Menthol Pastilles safe for children?

These pastilles are not suitable for children under 3 years of age. For children aged 3 and above, follow the age-appropriate dosage instructions on the pack carefully. If you're looking for cold remedies specifically designed for younger children, our baby and toddler range includes suitable alternatives. Always consult a pharmacist if you are unsure about the right product for your child's age.

Can I use Olbas Oil Menthol Pastilles during pregnancy?

If you are pregnant or breastfeeding, you should speak to your GP or pharmacist before using these pastilles. Some of the aromatic oils in the blend — particularly those derived from plants with salicylate-like compounds — may not be recommended during pregnancy. Your healthcare provider can advise on the safest option for managing cold symptoms at this time.

What are the side effects of Olbas Oil Menthol Pastilles?

Most people use these pastilles without any problems. Possible side effects include mild mouth or throat irritation and, if too many are taken, nausea. Rarely, an allergic reaction may occur — signs include rash, swelling of the mouth or throat, or difficulty breathing, which require immediate medical attention. Stop use and contact a pharmacist if you notice anything unexpected.

How do I manage side effects of Olbas Oil Menthol Pastilles?

If you experience mild mouth irritation, try spacing out your pastilles more throughout the day and ensure you are not exceeding the recommended dose. Staying well hydrated can also help soothe any throat discomfort. For any more serious reactions, stop use immediately and seek advice from a pharmacist or GP.

Who is eligible to use Olbas Oil Menthol Pastilles?

These pastilles are suitable for adults and children aged 3 and over who are experiencing sore throat, nasal congestion, or catarrh associated with a cold. They are not suitable for anyone with a known allergy to menthol or any of the aromatic oils in the blend. Pregnant or breastfeeding individuals should seek pharmacist advice before use.

What happens if I take too many Olbas Oil Menthol Pastilles?

Taking more than the recommended daily dose may cause nausea, increased mouth irritation, or stomach upset. If you or someone else has taken a large quantity, contact NHS 111 or your nearest pharmacist for guidance. Always keep medicines out of the reach of children to prevent accidental ingestion.

What are alternatives to Olbas Oil Menthol Pastilles?

Alternatives include other menthol-based throat lozenges such as Vicks VapoDrops, Strepsils Menthol, or plain menthol sweets. For broader cold and flu symptom relief, you can explore our full cold and flu range. Your pharmacist can help you identify the most appropriate product based on your specific symptoms.

How long can I use Olbas Oil Menthol Pastilles for?

These pastilles are intended for short-term symptomatic relief. If your symptoms have not improved after 3 to 5 days of use, or if they worsen at any point, you should stop using the pastilles and consult a pharmacist or GP. Prolonged self-treatment of a sore throat without medical review is not recommended.

Do Olbas Oil Menthol Pastilles actually clear a blocked nose?

They do not physically unblock the nasal passages in the way a decongestant nasal spray would. Instead, the menthol and aromatic vapours stimulate cold receptors in the nasal lining, which creates the sensation of easier breathing. Many people find this sensation genuinely helpful during a cold, even though airflow is not measurably increased.

Can I use Olbas Oil Menthol Pastilles alongside other cold medicines?

Generally, yes — these pastilles can be used alongside paracetamol or ibuprofen for pain and fever relief, as there are no known significant interactions at standard OTC doses. However, avoid combining them with other products containing the same aromatic oils to prevent overexposure. If you are taking any prescribed medicines, check with your pharmacist first.

What is the latest research on menthol pastilles for colds?

Research confirms that menthol activates TRPM8 cold-sensitive receptors in the nasal mucosa, producing a subjective sensation of improved airflow — though studies note this is a perceptual effect rather than a measurable increase in nasal patency. The NHS acknowledges that while there is no cure for the common cold, symptomatic remedies including menthol-based products can help manage discomfort. Current evidence supports their use for short-term relief of throat and nasal symptoms.

How Should You Use Olbas Oil Menthol Pastilles?

Using these pastilles correctly makes a real difference to how effective they feel. The key is to let the pastille do its work slowly rather than rushing through it.

Avoid eating or drinking immediately after use, as this can reduce the duration of the soothing effect in your throat.

What Is the Correct Dose of Olbas Oil Menthol Pastilles?

Always follow the dosage instructions on the product packaging. The table below provides a general guide, but the pack leaflet takes precedence if there is any difference.

Never give these pastilles to a child under 3 years of age. If you are unsure about the appropriate dose for a child, speak to a pharmacist before use.

When Is the Best Time to Use Olbas Oil Menthol Pastilles?

There is no fixed time of day for using these pastilles — you can take them whenever your symptoms feel most troublesome. Many people find them particularly helpful in the morning when nasal congestion tends to be at its worst, or in the evening to ease a sore throat before sleep. They are also convenient to use during the working day as they are discreet and non-drowsy, so they won't affect your concentration or ability to drive.

If you are using them to help with sleep, allow the pastille to dissolve fully before lying down to avoid any risk of choking.

How Long Can You Use Olbas Oil Menthol Pastilles For?

These pastilles are designed for short-term use during the symptomatic phase of a cold or mild upper respiratory tract infection. Most colds resolve within 7 to 10 days according to NHS guidance. If your symptoms have not improved after 3 to 5 days of using the pastilles, or if they worsen at any point, stop use and consult a pharmacist or GP. Persistent sore throat or nasal symptoms may indicate a secondary infection or another condition that requires medical assessment.

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

What Are the Most Common Side Effects of Olbas Oil Menthol Pastilles?

The majority of people who use Olbas Oil Menthol Pastilles experience no side effects at all. The cooling, tingling sensation in the mouth and throat is an expected part of how the product works — it is not a side effect. That said, a small number of users may notice the following:

  • Mild tingling or burning sensation in the mouth, particularly on first use
  • Temporary increase in saliva production as the pastille dissolves
  • A strong menthol taste that some people find intense

These effects are generally mild and resolve quickly once the pastille has fully dissolved.

What Are the Less Common Side Effects of Olbas Oil Menthol Pastilles?

Less commonly, some individuals may experience the following, particularly if the pastilles are used more frequently than recommended:

  • Mild irritation or soreness of the mouth lining or throat
  • Nausea or stomach discomfort if too many pastilles are taken in a short period
  • Headache — though this is difficult to attribute directly to the pastilles rather than the underlying cold
  • Dry mouth after the cooling effect wears off

If you notice any of these effects, reduce the frequency of use and ensure you are staying within the recommended daily dose.

What Are the Serious Side Effects of Olbas Oil Menthol Pastilles?

Serious side effects are rare but can occur, most commonly as a result of an allergic reaction to one of the aromatic oils in the blend. Signs of a serious allergic reaction (anaphylaxis) include:

  • Swelling of the lips, tongue, throat, or face
  • Difficulty breathing or swallowing
  • Skin rash, hives, or widespread itching
  • Dizziness or feeling faint

If you experience any of these symptoms, stop using the pastilles immediately and call 999 or go to your nearest A&E department. Do not wait to see if symptoms improve on their own.

What Should You Do If You Experience Side Effects?

For mild side effects such as mouth irritation or nausea, simply stop using the pastilles and allow the symptoms to settle. Drinking water can help soothe any residual throat discomfort. If you are concerned that a side effect may be related to an interaction with another medicine you are taking, speak to your pharmacist as soon as possible — they can review your full medication list and advise accordingly.

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 monitoring across the UK.

Can Olbas Oil Menthol Pastilles Interact With Other Medicines?

No clinically significant drug interactions have been reported with Olbas Oil Menthol Pastilles at standard over-the-counter doses. However, wintergreen oil — one of the components of the Olbas Oil blend — contains methyl salicylate, which is chemically related to aspirin. If you are taking anticoagulant medicines such as warfarin, or if you have been advised to avoid salicylates, speak to your pharmacist before use. Similarly, if you are taking any prescribed medicines for a chronic condition, a quick check with your pharmacist is always a sensible precaution.

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