What Is Chloraseptic Throat Spray and How Does It Help?

 

A sore throat can make even the simplest things — swallowing, talking, drinking a cup of tea — feel genuinely miserable. Chloraseptic throat spray is a fast-acting, over-the-counter option designed to take the edge off that pain quickly, without the need for a prescription. Ultra Chloraseptic Anaesthetic Throat Spray Cherry 15ml contains benzocaine 0.71% w/v as its active ingredient, a well-established local anaesthetic used to temporarily numb the throat and reduce discomfort. The cherry flavour makes it a little more pleasant to use, which matters when your throat is already irritated. You can browse our full range of cold and flu remedies if you need additional support alongside this spray.

Sore throats are one of the most common reasons people visit a pharmacist in the UK. According to the NHS, most sore throats are caused by viral infections and will resolve on their own within a week, but that doesn't make the discomfort any easier to live with in the meantime. This spray offers targeted, localised relief right where you need it.

 

How Does Ultra Chloraseptic Throat Spray Work?

 

The active ingredient, benzocaine, belongs to a class of medicines called local anaesthetics. When you spray it onto the back of your throat, it temporarily blocks the sodium channels in the nerve endings of the throat lining. This interrupts the pain signals being sent to your brain, producing a numbing effect within seconds. It doesn't treat the underlying cause of your sore throat — whether that's a virus, bacteria, or irritation — but it does make the symptoms significantly more manageable.

  • Benzocaine binds to nerve cell membranes in the throat lining
  • Sodium channel activity is temporarily blocked
  • Pain signal transmission to the brain is interrupted
  • Localised numbness provides short-term symptomatic relief

 

Who Should Use Ultra Chloraseptic Throat Spray?

 

This spray is suitable for adults and children aged 6 years and over who are experiencing a sore throat. It's particularly useful when you need quick relief — before a meal, before a meeting, or simply to get through the day more comfortably. That said, it's not appropriate for everyone, and there are some groups who should exercise caution or avoid it altogether.

  • Adults with a sore throat caused by a cold, flu, or mild infection
  • Children aged 6 and over (under adult supervision only)
  • People who need fast, localised throat pain relief without systemic medication
  • Those who find swallowing tablets or capsules difficult due to throat pain

Specifications of Ultra Chloraseptic Anaesthetic Throat Spray Cherry 15ml

 

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

 

Ultra Chloraseptic Anaesthetic Throat Spray Cherry 15ml is an over-the-counter medicine used to relieve the pain and discomfort of a sore throat. It contains benzocaine 0.71% w/v, a local anaesthetic that temporarily numbs the affected area. It is used for symptomatic relief only — it does not treat the underlying cause of a sore throat, whether viral or bacterial. The NHS advises that most sore throats clear up on their own within a week, but symptomatic relief can make that time considerably more comfortable.

 

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. There are certain situations where you should not use it, and others where you should seek advice first.

Do not use this spray if you:

  • Are allergic to benzocaine, any other local anaesthetic, or any other ingredient in the spray
  • Are under 6 years of age
  • Have a known hypersensitivity to para-aminobenzoic acid (PABA) derivatives
  • Have a condition called methaemoglobinaemia

Speak to your pharmacist or GP before use if you:

  • Are pregnant or breastfeeding
  • Have liver disease
  • Are taking medicines that may interact with benzocaine
  • Have a sore throat that is severe, persistent beyond 3 days, or accompanied by high fever, rash, or difficulty breathing

Known drug interactions:

  • No clinically significant interactions are known at OTC doses; however, benzocaine may theoretically interact with other local anaesthetics if used concurrently
  • Inform your pharmacist of all medicines you are taking, including herbal remedies

 

How Should You Use Ultra Chloraseptic Throat Spray?

 

Always use this spray exactly as directed on the label. Do not exceed the stated dose. If you are unsure, ask your pharmacist for guidance. For additional pain management options, you might also find our pain relief collection useful alongside this product.

  1. Remove the cap from the spray nozzle
  2. Open your mouth wide and point the nozzle towards the back of your throat
  3. Press the pump firmly to release 3 sprays directly onto the sore area
  4. Wait approximately 15 seconds before swallowing
  5. Replace the cap after use
  6. Repeat every 2 hours if needed, but do not exceed 8 doses (24 sprays) in any 24-hour period
Indication Age Group Dose Frequency
Sore throat pain relief Adults and children 6+ 3 sprays Every 2 hours; max 8 doses per 24 hours
Sore throat pain relief Under 6 years Not recommended Not applicable

 

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

 

Like all medicines, this spray can cause side effects, although not everyone will experience them. Most side effects are mild and related to the local anaesthetic action of benzocaine.

Common side effects:

  • Temporary numbness or tingling in the mouth and throat — this is expected and part of how the medicine works
  • Mild burning or stinging sensation immediately after application

Less common side effects:

  • Hypersensitivity or allergic reactions (rash, itching, swelling)
  • Methaemoglobinaemia — a rare but serious condition where the blood's ability to carry oxygen is reduced; seek immediate medical attention if you notice pale, grey, or blue-tinged skin, shortness of breath, or fatigue after use
  • Contact dermatitis around the mouth in rare cases

Stop using the spray and seek medical advice immediately if you experience any signs of a serious allergic reaction, including swelling of the face, lips, or throat, or difficulty breathing.

 

How Should You Store Ultra Chloraseptic Throat Spray?

 

Correct storage helps maintain the effectiveness and safety of this medicine. If you're also managing other health products at home, our vitamins and supplements collection has further guidance on general health maintenance.

  • Store below 25°C in a cool, dry place
  • Do not freeze

  • Do not use after the expiry date printed on the label

Frequently Asked Questions

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

You can buy Ultra Chloraseptic Anaesthetic Throat Spray Cherry 15ml directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £4.99. It's available without a prescription and can be delivered to your door. You'll also find it alongside other cold and flu remedies on our site if you need additional products.

How does chloraseptic throat spray work in the body?

The active ingredient, benzocaine 0.71% w/v, is a local anaesthetic that works by temporarily blocking sodium channels in the nerve endings of the throat lining. This interrupts pain signals before they reach the brain, producing a numbing effect within seconds of application. It acts locally — it doesn't enter the bloodstream in significant amounts at the doses used in this spray.

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

Open your mouth wide and direct the nozzle towards the back of your throat, then press the pump to release 3 sprays. Wait around 15 seconds before swallowing to allow the benzocaine to take effect. You can repeat this every 2 hours, but do not use more than 8 doses (24 sprays) in any 24-hour period.

How quickly does chloraseptic throat spray start working?

Ultra Chloraseptic Throat Spray typically begins to numb throat pain within seconds of application, as benzocaine acts directly on local nerve endings in the throat. The numbing effect is short-lived, which is why you can reapply every 2 hours as needed. It is not a cure for the underlying cause of your sore throat, so if symptoms persist beyond 3 days, see your GP.

What is the correct dose of Ultra Chloraseptic Throat Spray for adults?

The recommended dose for adults is 3 sprays directed to the back of the throat, repeated every 2 hours as needed. You should not exceed 8 doses (24 sprays) in any 24-hour period. Always read the product label before use and consult your pharmacist if you have any questions about dosing.

Can children use Ultra Chloraseptic Throat Spray?

Ultra Chloraseptic Throat Spray is not suitable for children under 6 years of age. For children aged 6 and over, it can be used under adult supervision at the same dose as adults — 3 sprays every 2 hours, up to 8 doses per day. If you are unsure whether this product is appropriate for your child, speak to a pharmacist before use.

What are the side effects of Ultra Chloraseptic Throat Spray?

The most common side effect is temporary numbness or tingling in the mouth and throat, which is the intended effect of benzocaine. Less commonly, some people may experience a mild burning sensation, or in rare cases, a hypersensitivity reaction such as rash or swelling. Stop use immediately and seek medical attention if you notice any signs of a serious allergic reaction or unusual symptoms such as blue-tinged skin or difficulty breathing.

Who should not use Ultra Chloraseptic Throat Spray?

You should not use this spray if you are allergic to benzocaine or any other local anaesthetic, or if you have a condition called methaemoglobinaemia. It is also not suitable for children under 6 years old. Pregnant or breastfeeding women and people with liver disease should speak to a pharmacist or GP before use.

How long can I use Ultra Chloraseptic Throat Spray for?

This spray is intended for short-term symptomatic relief only. If your sore throat has not improved after 3 days of use, or if it worsens at any point, you should stop using the spray and consult your GP. Prolonged use without medical supervision is not recommended, as a persistent sore throat may indicate an underlying condition that needs assessment.

Can I use Ultra Chloraseptic Throat Spray if I am pregnant?

If you are pregnant or breastfeeding, you should speak to your GP or pharmacist before using this spray. While benzocaine is applied locally and systemic absorption is minimal at OTC doses, it is always best to seek professional advice before using any medicine during pregnancy. Your pharmacist can help you weigh up the benefits and any potential risks.

Does Ultra Chloraseptic Throat Spray interact with other medicines?

No clinically significant drug interactions are known at the doses used in this over-the-counter spray. However, you should always inform your pharmacist of all medicines you are taking — including prescription medicines, over-the-counter products, and herbal remedies — before starting any new treatment. If you are taking medicines for heart conditions or blood disorders, seek specific advice before use.

What happens if I accidentally swallow Ultra Chloraseptic Throat Spray?

Swallowing a small amount of the spray as directed is expected and not harmful — you are instructed to wait 15 seconds before swallowing after each application. However, if you or a child accidentally swallows a large amount of the product, contact NHS 111 or your nearest A&E immediately. Keep the packaging with you so medical staff can identify the ingredients quickly.

What are the alternatives to chloraseptic throat spray?

Alternatives include throat lozenges containing benzocaine or lidocaine, antiseptic gargles such as those containing chlorhexidine or povidone-iodine, and systemic pain relief medicines such as paracetamol or ibuprofen. You can explore our ear, nose and throat collection for a range of options. Your pharmacist can advise on the most suitable choice based on your symptoms.

Is Ultra Chloraseptic Throat Spray suitable for people with diabetes?

The spray itself does not contain significant amounts of sugar and is applied locally to the throat, so it is unlikely to affect blood glucose levels. However, if you have diabetes and are unwell with a sore throat, it is worth monitoring your blood glucose more closely, as illness can affect glucose control. Speak to your pharmacist or GP if you have any specific concerns about using this product alongside your diabetes management.

What is the latest research on benzocaine throat sprays?

Benzocaine has been used as a local anaesthetic for many decades and its mechanism of action — sodium channel blockade — is well established in clinical literature. Regulatory bodies including the MHRA continue to monitor the safety of benzocaine-containing products, particularly regarding the rare risk of methaemoglobinaemia. Current guidance supports its use at OTC doses for short-term sore throat relief in adults and children aged 6 and over, provided the product is used as directed.

How Should You Use Ultra Chloraseptic Anaesthetic Throat Spray?

Using this spray correctly ensures you get the most effective relief from your sore throat. Always read the label before use and follow the instructions carefully — it only takes a few seconds to apply and the numbing effect begins almost immediately.

Here is a step-by-step guide to using the spray:

What Is the Correct Dose of Ultra Chloraseptic Throat Spray?

The dose is the same for adults and children aged 6 and over. Do not use more than the recommended number of sprays per dose, and do not apply more frequently than every 2 hours. Exceeding the stated dose does not improve relief and may increase the risk of side effects.

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

There is no fixed time of day for using this spray — you apply it whenever your throat pain is troublesome. Many people find it particularly helpful before meals, as swallowing can be especially painful when you have a sore throat. Using it shortly before eating or drinking can make mealtimes much more manageable.

It can also be useful before important conversations, meetings, or any situation where you need to speak clearly without discomfort. Just remember to allow the 15-second wait time before swallowing after each application, and keep track of how many doses you have used throughout the day so you don't exceed the maximum of 8 doses in 24 hours.

How Long Can You Use Ultra Chloraseptic Throat Spray For?

This spray is designed for short-term use only. Most sore throats caused by viral infections resolve within 7 days, and the spray should only be used for symptomatic relief during this period. If your symptoms have not improved after 3 days of use, or if they worsen at any point, stop using the spray and consult your GP or pharmacist promptly.

A sore throat that persists beyond a week, or one accompanied by a high fever, difficulty breathing, or a rash, may indicate a more serious condition that requires medical assessment. Do not continue using this spray as a substitute for seeking appropriate medical care.

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?

The most frequently reported side effect of this spray is temporary numbness or tingling in the mouth and throat. This is entirely expected — it is the intended action of benzocaine, the active local anaesthetic ingredient. The sensation typically fades within a short time after application.

  • Temporary numbness or tingling in the mouth and throat
  • Mild burning or stinging sensation immediately after spraying
  • Altered 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 reactions that go beyond the expected numbing effect. These are not typical but are worth being aware of before you use the spray for the first time.

  • Skin irritation or contact dermatitis around the lips or mouth
  • Mild swelling or redness of the oral mucosa
  • Nausea if a large amount is swallowed accidentally
  • Headache in rare cases

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

Serious side effects are rare but require immediate medical attention if they occur. The most significant risk associated with benzocaine-containing products is methaemoglobinaemia — a condition where the blood's ability to carry oxygen is reduced. This is more likely with excessive use or in people with certain genetic conditions. Symptoms include pale, grey, or blue-tinged skin (particularly around the lips and fingernails), shortness of breath, rapid heart rate, and unusual fatigue. Stop using the spray immediately and call 999 or go to your nearest A&E if you notice any of these symptoms.

Serious allergic reactions (anaphylaxis) are also possible, though very rare. Signs include sudden swelling of the face, lips, tongue, or throat, difficulty breathing, or a widespread skin rash. This is a medical emergency — call 999 immediately.

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

For mild side effects such as temporary numbness or a brief stinging sensation, no action is usually needed — these will resolve on their own. If you experience any side effect that concerns you, or one that does not resolve quickly, stop using the spray and 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.

Can Ultra Chloraseptic Throat Spray Interact With Other Medicines?

No clinically significant drug interactions are known at the doses used in this over-the-counter spray. Benzocaine is applied locally and systemic absorption is minimal. However, you should always tell your pharmacist about all medicines you are taking — including prescription drugs, other OTC products, and herbal supplements — before starting any new treatment. People taking medicines that affect blood oxygen levels or those with a history of blood disorders should seek specific advice before use.

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