What Is Chloraseptic Throat Spray and How Does It Help?

 

A sore throat can stop you in your tracks. Whether it's the scratchy, raw feeling that arrives with a cold or the sharper pain that makes swallowing feel like a chore, you want relief — and you want it quickly. Chloraseptic throat spray has been a trusted name in sore throat relief for decades, and the Ultra Chloraseptic Original Menthol Throat Spray 15ml brings that same targeted action in a compact, easy-to-use bottle. Available over the counter for just £4.99, it's a practical option to keep in your medicine cabinet during cold and flu season. If you're looking for other cold and flu remedies, you can browse our full Cold and Flu collection at Cured Pharmacy.

The active ingredient is phenol 1.4% w/v — a well-established antiseptic and local anaesthetic used in throat preparations. Phenol works directly at the site of discomfort, temporarily numbing the throat lining to ease pain while also providing mild antiseptic action. The menthol flavour adds a cooling sensation that many people find soothing. It's a straightforward, no-fuss product designed to do one thing well: take the edge off a sore throat fast.

 

How Does Ultra Chloraseptic Menthol Throat Spray Work?

 

Understanding how a medicine works helps you use it with confidence. Ultra Chloraseptic acts locally — meaning it works right where you spray it, rather than being absorbed into your bloodstream. Here's what happens when you use it:

  • Local anaesthetic action: Phenol temporarily blocks nerve signals in the throat lining, reducing the sensation of pain within seconds of application.
  • Antiseptic effect: Phenol has recognised antiseptic properties, helping to reduce bacterial presence at the site of irritation.
  • Cooling sensation: The menthol formulation creates a cooling effect that can make the throat feel more comfortable almost immediately.
  • Targeted delivery: The spray nozzle directs the medicine precisely to the back of the throat, where discomfort is usually most intense.

Because the action is local rather than systemic, onset is rapid — most people notice relief within a minute or two of spraying. This makes it particularly useful before meals or when you need to speak or swallow comfortably.

 

Who Should Use Ultra Chloraseptic Original Menthol Throat Spray?

 

This spray is suitable for a wide range of people dealing with mild to moderate sore throat pain. It's especially handy when you need fast, localised relief without reaching for systemic pain relief. That said, it's not right for everyone — always read the label before use.

Ultra Chloraseptic Original Menthol Throat Spray is generally suitable for:

  • Adults and teenagers aged 12 and over (standard adult dosing)
  • Children aged 6 to 11 years (at the appropriate reduced dose — see dosage section)
  • People with a sore throat associated with a cold, flu, or mild upper respiratory tract infection
  • Those who prefer a topical spray over tablets or lozenges

It is not suitable for children under 6 years of age. People with a known hypersensitivity to phenol or any other ingredient in the formulation should avoid this product. If your sore throat is severe, accompanied by a high fever, difficulty breathing, or lasts longer than three days, you should seek medical advice rather than continuing to self-treat.

What Is Ultra Chloraseptic Menthol Throat Spray and What Is It Used For?

 

Ultra Chloraseptic Original Menthol Throat Spray is an over-the-counter medicine used to relieve the pain and discomfort of a sore throat. It contains phenol 1.4% w/v as its active ingredient, which acts as both a local anaesthetic and an antiseptic. It is used to provide short-term symptomatic relief from sore throat pain in adults and children aged 6 years and over. It is not a treatment for the underlying cause of a sore throat — rather, it manages the pain while your body recovers. The NHS notes that most sore throats clear up on their own within a week, and self-care measures including appropriate OTC medicines can help manage symptoms in the meantime.

 

What Do You Need to Know Before Using Ultra Chloraseptic Throat Spray?

 

Before using this spray, it's important to check whether it's appropriate for you. Do not use Ultra Chloraseptic Original Menthol Throat Spray if any of the following apply:

  • You are allergic to phenol or any other ingredient in the formulation
  • Your child is under 6 years of age
  • You have a known hypersensitivity to local anaesthetics
  • Your sore throat is severe, accompanied by a high fever (above 38°C), difficulty swallowing, or a skin rash — these may indicate a more serious condition requiring medical assessment
  • Your symptoms have not improved after 3 days of use

Speak to your pharmacist or GP before using this product if you are pregnant or breastfeeding, as safety data for phenol-based throat sprays in pregnancy is limited and professional guidance is recommended. There are no clinically significant drug interactions known at the doses used in this OTC product, but always inform your pharmacist of any other medicines you are taking.

  • No significant interactions with common OTC medicines have been identified at standard doses
  • If you are taking immunosuppressant medicines or have a compromised immune system, seek medical advice before self-treating a sore throat

 

How Should You Use Ultra Chloraseptic Original Menthol Throat Spray?

 

Using this spray correctly ensures you get the most from each dose. Follow these steps carefully:

  1. Remove the cap from the spray bottle.
  2. Point the nozzle towards the back of your throat, keeping your mouth open wide.
  3. Press the pump firmly to release the spray — 3 sprays per dose for adults and children aged 12 and over.
  4. Allow the spray to coat the back of the throat. Try not to swallow immediately.
  5. Replace the cap after use and store the bottle safely.
  6. Repeat every 2 hours as needed, but do not exceed the maximum number of doses in 24 hours.
Age Group Dose Frequency Maximum Daily Doses
Adults and children 12+ 3 sprays Every 2 hours 6 times in 24 hours
Children aged 6–11 3 sprays Every 2 hours 6 times in 24 hours (under adult supervision)
Children under 6 Not suitable — do not use

 

What Are the Possible Side Effects of Ultra Chloraseptic Throat Spray?

 

Like all medicines, Ultra Chloraseptic can cause side effects, although not everyone experiences them. Because the spray acts locally in the throat, systemic side effects are uncommon. If you experience any unexpected or concerning symptoms, stop using the product and speak to a pharmacist or GP. You can also report suspected side effects to the MHRA via the Yellow Card scheme.

Common side effects (may affect a small number of users):

  • Temporary numbness or tingling in the mouth and throat
  • Mild burning or stinging sensation at the site of application
  • Altered taste sensation immediately after use

Less common side effects (rare but possible):

  • Localised irritation or redness in the mouth or throat
  • Hypersensitivity reactions — including rash, itching, or swelling — particularly in those with a known sensitivity to phenol
  • In very rare cases, signs of a serious allergic reaction (anaphylaxis) such as swelling of the face, lips, or throat, or difficulty breathing — seek emergency medical help immediately if this occurs

 

How Should You Store Ultra Chloraseptic Original Menthol Throat Spray?

 

Correct storage keeps the product safe and effective for its full shelf life. Follow these storage instructions:

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and sources of heat
  • Do not freeze
  • Keep the bottle tightly capped when not in use
  • Keep out of the sight and reach of children
  • Do not use after the expiry date printed on the bottle or carton
  • Do not dispose of medicines via wastewater or household waste — return unused medicines to your pharmacy

If you're managing a range of symptoms during cold and flu season, it's worth exploring our Pain Relief collection for complementary options such as paracetamol or ibuprofen, which can help with fever and general aches alongside a sore throat spray. For broader immune and wellness support, our Vitamins and Supplements collection includes vitamin C and zinc products that are commonly used during winter months.

Frequently Asked Questions

Where can I buy Ultra Chloraseptic Throat Spray online in the UK?

You can buy Ultra Chloraseptic Original Menthol Throat Spray 15ml directly from Cured Pharmacy online for £4.99, with fast UK-wide delivery. It is a General Sale List (GSL) medicine, so no prescription is needed. It is also available in many high street pharmacies and supermarkets across the UK.

How does chloraseptic throat spray work in the body?

Ultra Chloraseptic contains phenol 1.4% w/v, which acts as a local anaesthetic by temporarily blocking pain signals in the nerve endings of the throat lining. It also has mild antiseptic properties, helping to reduce bacterial load at the site of irritation. Because it works locally rather than systemically, it does not enter the bloodstream in significant amounts at the doses used.

How do I use Ultra Chloraseptic Throat Spray step by step?

Remove the cap, open your mouth wide, and point the nozzle towards the back of your throat. Press the pump to release 3 sprays, then try to avoid swallowing immediately to allow the medicine to coat the throat. You can repeat this every 2 hours, up to a maximum of 6 times in any 24-hour period.

What is the correct dose of Ultra Chloraseptic for adults?

Adults and young people aged 12 and over should use 3 sprays directed to the back of the throat per dose. This can be repeated every 2 hours but should not exceed 6 doses in a 24-hour period. Always follow the instructions on the product label or as directed by your pharmacist.

Can children use Ultra Chloraseptic Menthol Throat Spray?

Yes — Ultra Chloraseptic is suitable for children aged 6 years and over, using the same dose of 3 sprays every 2 hours under adult supervision. It must not be used in children under 6 years of age. If your child's sore throat is severe or accompanied by a high fever, consult your GP rather than self-treating.

What are the side effects of Ultra Chloraseptic Throat Spray?

Most people tolerate Ultra Chloraseptic well, but some may experience temporary numbness, tingling, or a mild burning sensation in the mouth and throat after use. Rarely, localised irritation or hypersensitivity reactions such as rash or swelling may occur. If you notice any signs of a serious allergic reaction — such as swelling of the face or difficulty breathing — stop use immediately and seek emergency medical help.

How long can you use Ultra Chloraseptic Throat Spray for?

You should not use Ultra Chloraseptic for more than 3 consecutive days without seeking advice from a pharmacist or GP. Most sore throats caused by viral infections resolve within 7 to 10 days, but if your symptoms persist, worsen, or are accompanied by a high fever or difficulty swallowing, you should seek medical assessment. Prolonged self-treatment without improvement may indicate a condition that needs professional attention.

Is Ultra Chloraseptic safe to use during pregnancy?

Safety data for phenol-based throat sprays during pregnancy is limited, and it is advisable to speak to your GP or midwife before using this product if you are pregnant or breastfeeding. Your healthcare professional can recommend the most appropriate option for managing sore throat symptoms safely during pregnancy. Do not self-treat without seeking guidance first.

What happens if I use too much Ultra Chloraseptic Throat Spray?

Using more than the recommended dose is unlikely to cause serious harm when used as directed, but exceeding the maximum of 6 doses in 24 hours is not advised. If you accidentally swallow a large amount of the spray or a child ingests the product, contact NHS 111 or your nearest A&E for advice. Always keep the bottle out of reach of children.

What are alternatives to Ultra Chloraseptic Throat Spray?

Alternatives include benzydamine-based sprays such as Difflam, which has anti-inflammatory as well as local anaesthetic properties, or throat lozenges containing local anaesthetics such as lidocaine or benzocaine. Systemic pain relief such as paracetamol or ibuprofen can also help with sore throat pain and fever — you can explore options in our Pain Relief collection. Speak to your pharmacist to find the most suitable option for your symptoms.

Does Ultra Chloraseptic Throat Spray interact with other medicines?

No clinically significant drug interactions have been identified with Ultra Chloraseptic at the doses used in this OTC product. However, if you are taking prescription medicines — particularly immunosuppressants or medicines that affect the nervous system — it is always sensible to check with your pharmacist before adding any new product. Your pharmacist can review your full medicines list quickly and at no charge.

How quickly does Ultra Chloraseptic Throat Spray start working?

Most people notice a reduction in throat pain within a minute or two of applying the spray, as phenol acts rapidly on the local nerve endings in the throat lining. The numbing effect is temporary and will wear off after a period of time, which is why the spray can be reapplied every 2 hours as needed. It is designed for fast, short-term relief rather than long-lasting treatment.

Can I use Ultra Chloraseptic Throat Spray alongside cold and flu remedies?

In most cases, yes — Ultra Chloraseptic can be used alongside standard cold and flu remedies such as paracetamol-based products, decongestants, or cough medicines, as it acts locally in the throat rather than systemically. However, always check the ingredients of any combination cold and flu product to avoid accidentally doubling up on any active ingredient. If you're unsure, ask your pharmacist for advice. You can also browse our Cold and Flu collection for a range of complementary products.

What are the latest findings on phenol throat sprays for sore throat?

Phenol has been used as a topical antiseptic and local anaesthetic in throat preparations for many decades, and its efficacy for short-term sore throat pain relief is well established in clinical practice. Current NHS guidance supports the use of appropriate OTC medicines, including local anaesthetic throat sprays, for symptomatic relief of mild sore throats. There is no evidence to suggest that phenol-based sprays are harmful when used as directed for short periods.

Is Ultra Chloraseptic Throat Spray suitable for people with diabetes?

Ultra Chloraseptic Original Menthol Throat Spray does not contain significant amounts of sugar, and its local action means it is unlikely to affect blood glucose levels. However, if you have diabetes and are unwell with a sore throat, it is important to monitor your blood glucose more closely, as illness can affect glucose control. If you manage diabetes at home, our Diabetes Monitoring collection has a range of testing supplies to help you stay on top of your readings.

How Should You Use Ultra Chloraseptic Original Menthol Throat Spray?

Using Ultra Chloraseptic correctly is straightforward, but it's worth taking a moment to get the technique right so the spray reaches the back of the throat where it's needed most. Always wash your hands before handling the bottle, and check the expiry date before each use.

Follow these steps for each dose:

What Is the Correct Dose of Ultra Chloraseptic Throat Spray?

The dose is the same for adults and children aged 6 and over, but the maximum daily frequency must be observed carefully. Never exceed the recommended number of doses in a 24-hour period, and do not give this product to children under 6 years of age under any circumstances.

When Is the Best Time to Use Ultra Chloraseptic Throat Spray?

There is no fixed time of day for using this spray — it is used on an as-needed basis whenever throat pain is troublesome. Many people find it particularly helpful before meals, as swallowing can be especially uncomfortable when a sore throat is at its worst. Using a dose before eating can make mealtimes more manageable and help you maintain adequate nutrition and hydration during illness.

It can also be useful before speaking for extended periods — for example, if you need to attend work or a meeting despite having a sore throat. Just remember to keep track of how many doses you have used throughout the day to avoid exceeding the maximum of 6 doses in 24 hours.

How Long Can You Use Ultra Chloraseptic Throat Spray For?

Ultra Chloraseptic is intended for short-term use only. You should not use it for more than 3 consecutive days without consulting a pharmacist or GP. If your sore throat has not improved after 3 days, or if it worsens at any point, it is important to seek professional medical advice rather than continuing to self-treat. A persistent or worsening sore throat may indicate a bacterial infection such as tonsillitis or strep throat, which may require antibiotic treatment.

If symptoms resolve before 3 days, you can stop using the spray as soon as you feel comfortable. There is no need to complete a fixed course — use it only for as long as symptoms require relief.

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

What Are the Most Common Side Effects of Ultra Chloraseptic Throat Spray?

Ultra Chloraseptic Original Menthol Throat Spray is generally well tolerated when used as directed. Because it acts locally in the throat rather than being absorbed into the bloodstream, systemic side effects are uncommon. The most frequently reported effects are directly related to the local anaesthetic action of phenol and are usually mild and short-lived.

  • Temporary numbness or tingling in the mouth and throat
  • Mild burning or stinging sensation immediately after application
  • Altered or reduced taste sensation for a short period after use

What Are the Less Common Side Effects of Ultra Chloraseptic Throat Spray?

Less commonly, some people may experience localised irritation or a mild reaction at the site of application. These effects are not typical but are worth being aware of, particularly if you have a history of sensitivity to antiseptic products or local anaesthetics.

  • Localised redness or irritation in the mouth or throat
  • Dry or uncomfortable sensation in the throat following repeated use
  • Mild nausea if a significant amount of the spray is accidentally swallowed

What Are the Serious Side Effects of Ultra Chloraseptic Throat Spray?

Serious side effects are rare but can occur in people with a hypersensitivity to phenol or other ingredients in the formulation. If you experience any of the following, stop using the product immediately and seek urgent medical attention.

  • Swelling of the face, lips, tongue, or throat (angioedema)
  • Difficulty breathing or swallowing
  • Widespread skin rash, hives, or itching
  • Dizziness or feeling faint

These symptoms may indicate a serious allergic reaction (anaphylaxis), which is a medical emergency. Call 999 or go to your nearest A&E immediately if you suspect anaphylaxis.

What Should You Do If You Experience Side Effects of Ultra Chloraseptic?

For mild side effects such as temporary numbness or tingling, no action is usually needed — these effects resolve on their own within a short time. If you find the sensation uncomfortable, you can reduce the frequency of use or try an alternative sore throat remedy. For any side effect that concerns you, or that does not resolve, speak to your pharmacist or GP. 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 Ultra Chloraseptic Throat Spray Interact With Other Medicines?

No clinically significant interactions between Ultra Chloraseptic and other commonly used medicines have been identified at the doses used in this OTC product. Because phenol acts locally in the throat and is not absorbed systemically in meaningful amounts at these doses, the risk of interaction with other medicines is considered very low. However, if you are taking prescription medicines — particularly those that affect the immune system or nervous system — it is always good practice to check with your pharmacist before using any new product. Your pharmacist can review your medicines quickly and advise you on the safest approach.

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