Is a Throat Spray for Sore Throat Right for You?

 

A sore throat can stop you in your tracks. Whether it hits first thing in the morning or creeps up during a long day, that raw, scratchy pain is hard to ignore. Ultra Chloraseptic Anaesthetic Throat Spray 15ml is an over-the-counter local anaesthetic spray designed to target throat pain directly at the source, giving you fast-acting relief when you need it most. If you're looking for a throat spray for sore throat that gets to work quickly without the need for a prescription, this could be exactly what you need. You can browse our full range of cold and flu remedies to find the right combination of products for your symptoms.

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. In the meantime, symptomatic relief is key — and a targeted anaesthetic spray can make a real difference to your comfort and ability to eat, drink, and speak normally.

 

How Does Ultra Chloraseptic Throat Spray Work?

 

The active ingredient in this spray is benzocaine 0.71% w/v, a well-established local anaesthetic used in a range of OTC medicines. Here's how it works:

  • Benzocaine is sprayed directly onto the mucous membranes at the back of the throat.
  • It temporarily blocks sodium channels in the nerve cell membranes of the throat lining.
  • This interrupts the transmission of pain signals to the brain.
  • The numbing effect typically begins within seconds of application.
  • Relief lasts for a short period, allowing you to eat, drink, or swallow more comfortably.

Because benzocaine acts locally rather than being absorbed into the bloodstream in significant amounts at OTC doses, it has a well-established safety profile when used as directed. It does not treat the underlying cause of a sore throat — it simply manages the pain while your body recovers.

 

Who Is Ultra Chloraseptic Throat Spray Suitable For?

 

This spray is suitable for a wide range of people dealing with throat discomfort. It's particularly useful if you need targeted, rapid relief without taking oral tablets or capsules. It is appropriate for:

  • Adults and teenagers experiencing a sore throat due to a cold, flu, or viral infection
  • Children aged 6 years and over (at the correct dose, under adult supervision)
  • People who struggle to swallow tablets and prefer a spray format
  • Those who need relief during the day without drowsiness or systemic effects

It is not suitable for children under 6 years of age. People with a known hypersensitivity to benzocaine or other ester-type local anaesthetics should not use this product. If you are pregnant or breastfeeding, speak to your pharmacist or GP before use.

How Should You Store Ultra Chloraseptic Throat Spray?

Do not use the spray after the expiry date printed on the label. If you're managing multiple symptoms at once, you might also find our pain relief collection helpful for complementary options such as paracetamol or ibuprofen to address fever or general aches alongside your throat discomfort.

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

 

Ultra Chloraseptic Anaesthetic Throat Spray 15ml is an over-the-counter oropharyngeal spray containing benzocaine 0.71% w/v as its active ingredient. It is used to provide temporary relief from the pain and discomfort of sore throats in adults and children aged 6 years and over. Sore throats are most commonly caused by viral upper respiratory tract infections — the kind that accompany a cold or flu — and while they usually resolve without treatment, managing the pain in the meantime is important for day-to-day comfort. This spray works locally, meaning it acts directly on the throat lining rather than being absorbed into the body in significant amounts.

 

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

 

Before using this spray, it's important to check that it is appropriate for you. Do not use this product if any of the following apply:

  • You are allergic to benzocaine or any other ester-type local anaesthetic
  • You are allergic to any other ingredient in the formulation
  • The person using it is under 6 years of age
  • You have a condition called methaemoglobinaemia (a rare blood disorder)

Speak to your pharmacist or GP before using this spray if you are pregnant, breastfeeding, or have any underlying health conditions affecting your mouth or throat. You should also seek medical advice if your sore throat is severe, accompanied by a high fever, difficulty breathing, or a rash — these may indicate a more serious condition requiring medical assessment.

Regarding drug interactions, no clinically significant interactions are known at OTC doses of benzocaine spray. However, you should always inform your pharmacist of any other medicines you are taking, including herbal remedies and supplements. If you are managing other aspects of your health, our ear, nose and throat collection includes a range of products that may complement your care.

 

How Should You Use Ultra Chloraseptic Throat Spray?

 

Always use this spray exactly as directed on the label or as advised by your pharmacist. Follow these steps carefully:

  1. Remove the cap from the spray nozzle.
  2. Hold the bottle upright and point the nozzle towards the back of your throat.
  3. Press the pump firmly to release three sprays directly onto the affected area.
  4. Do not inhale the spray — direct it at the throat lining only.
  5. Replace the cap after use and store the bottle safely.
  6. Repeat every two to three hours as needed, up to the maximum daily dose.
Indication Age Group Dose Frequency

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
  • Mild burning or stinging sensation immediately after application

Less common side effects:

  • Localised irritation or redness of the throat lining
  • Allergic reactions such as rash, itching, or swelling (seek medical advice immediately if this occurs)
  • In very rare cases, benzocaine has been associated with methaemoglobinaemia — a serious condition affecting the blood's ability to carry oxygen. Stop use and seek urgent medical attention if you notice pale, grey, or blue-coloured skin, lips, or fingernails, or if you feel unusually short of breath.

If you experience any unexpected or concerning symptoms after using this spray, stop use immediately and contact your pharmacist or GP. You can also report side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

 

How Should You Store Ultra Chloraseptic Throat Spray?

  • Keep the bottle tightly capped when not in use.
  • Keep out of the reach and sight of children at all times.
  • Do not use after the expiry date printed on the bottle or outer packaging.

Frequently Asked Questions

How does benzocaine throat spray work in the body?

Benzocaine is a local anaesthetic that works by temporarily blocking sodium channels in the nerve endings of the throat lining. This interrupts the transmission of pain signals to the brain, producing a numbing effect within seconds of application. It acts locally and is not significantly absorbed into the bloodstream at OTC doses.

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

Remove the cap, point the nozzle towards the back of your throat, and press the pump to deliver three sprays. Avoid inhaling the spray — aim it directly at the sore area. Repeat every two to three hours as needed, and always replace the cap after use.

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

Adults should use three sprays directed to the back of the throat, repeated every two to three hours as needed. Do not exceed the recommended frequency of use. If symptoms persist beyond three days, consult your pharmacist or GP.

When is the best time to use a throat spray for sore throat relief?

You can use this throat spray for sore throat discomfort at any time of day — it's particularly helpful before meals or drinks when swallowing is most painful. It's also useful first thing in the morning when throat pain tends to be at its worst. Use it as needed throughout the day, staying within the recommended dosage.

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 expected and harmless. Some people may experience mild irritation or a stinging sensation at the application site. In very rare cases, benzocaine has been linked to a serious blood condition called methaemoglobinaemia — stop use and seek urgent medical help if you notice blue or grey discolouration of the lips or skin.

How do I manage side effects of benzocaine throat spray?

Temporary numbness is a normal and expected effect of benzocaine and will resolve on its own within a short time. If you experience irritation or discomfort that persists, stop using the spray and speak to your pharmacist. For any signs of an allergic reaction — such as swelling, rash, or difficulty breathing — seek medical attention immediately.

Can children use Ultra Chloraseptic Throat Spray?

Yes, Ultra Chloraseptic Throat Spray is suitable for children aged 6 years and over when used at the correct dose and under adult supervision. It must not be used in children under 6 years of age. Always read the label carefully before giving any medicine to a child.

Who is not eligible to use Ultra Chloraseptic Throat Spray?

This spray is not suitable for children under 6 years old, or for anyone with a known allergy to benzocaine or other ester-type local anaesthetics. People with methaemoglobinaemia should also avoid this product. If you are pregnant, breastfeeding, or have an underlying health condition, speak to your pharmacist or GP before use.

How long can you use Ultra Chloraseptic Throat Spray for?

This spray is intended for short-term use only. If your sore throat has not improved after three days of use, or if it worsens at any point, you should stop using the spray and seek advice from your GP or pharmacist. Prolonged use without medical supervision is not recommended.

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

Using more than the recommended dose increases the risk of side effects, including excessive numbness and, in rare cases, methaemoglobinaemia. If you think you or someone else has used too much, contact NHS 111 or your nearest A&E department for advice. Always keep medicines out of the reach of children.

What are the alternatives to Ultra Chloraseptic Throat Spray?

Alternatives include throat lozenges containing benzocaine or lidocaine, antiseptic gargles, and oral pain relief medicines such as ibuprofen or paracetamol, which can also help with fever. You can explore our full oral health collection for additional options. Speak to your pharmacist to find the most suitable product for your symptoms.

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

No clinically significant interactions are known between benzocaine throat spray and common cold and flu medicines at OTC doses. However, you should always check with your pharmacist before combining medicines, particularly if you are taking prescription medications. Our cold and flu collection includes a range of products that can be used alongside this spray.

Is Ultra Chloraseptic Throat Spray safe to use during pregnancy?

If you are pregnant or breastfeeding, you should speak to your GP or pharmacist before using this spray. While benzocaine acts locally and is not significantly absorbed into the bloodstream 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 risks.

What are the latest findings on benzocaine for sore throat relief?

Benzocaine has been used as a local anaesthetic in OTC throat products for many decades and remains a well-established option for short-term sore throat pain relief. Regulatory bodies including the MHRA continue to approve its use in OTC products at appropriate concentrations. The main area of ongoing safety awareness relates to the rare risk of methaemoglobinaemia, which is why following the recommended dose is essential.

How Should You Use Ultra Chloraseptic Anaesthetic Throat Spray?

Using this spray correctly ensures you get the most effective relief with the lowest risk of side effects. Always read the label before use and follow the instructions carefully. If you are unsure about anything, ask your pharmacist for guidance before starting.

Do not spray into the eyes or nose. If accidental contact occurs, rinse thoroughly with water and seek medical advice if irritation persists.

What Is the Correct Dose of Ultra Chloraseptic Throat Spray?

The dose varies depending on the age of the person using the spray. Always follow the recommended dose and do not use more frequently than advised. Using more than the recommended amount does not improve relief and increases the risk of side effects.

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

This spray can be used at any point during the day when throat pain is causing discomfort. Many people find it most helpful before meals, as swallowing food and drink can be particularly painful when the throat is inflamed. Using it shortly before eating allows the anaesthetic effect to take hold, making mealtimes more manageable. It is also useful first thing in the morning, when throat pain is often at its most intense after a night of mouth breathing.

You do not need to take it at fixed intervals — simply use it when you need relief, staying within the recommended dosage guidelines.

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 will begin to improve within three to five days, and the spray should only be used for as long as symptoms persist. If your sore throat has not improved after three days of using the spray, or if it gets worse rather than better, stop using it and consult your GP or pharmacist. They can assess whether a different treatment or further investigation is needed.

Do not use this spray continuously for extended periods without seeking medical advice. Prolonged use of local anaesthetics in the throat is not recommended without professional guidance.

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 an expected result of benzocaine's local anaesthetic action and is not a cause for concern — it will resolve on its own within a short time after application. Some people also notice a mild stinging or burning sensation immediately after spraying, which typically fades quickly.

  • Temporary numbness of the mouth and throat
  • Tingling sensation at the site of application
  • Mild stinging or burning immediately after use

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

Less commonly, some people may experience localised irritation or redness of the throat lining. Allergic reactions to benzocaine, while uncommon, can occur — particularly in people who have previously reacted to ester-type local anaesthetics. If you notice any signs of an allergic reaction, stop using the spray immediately and seek medical advice.

  • Localised throat irritation or redness
  • Skin rash or itching
  • Swelling of the mouth, lips, or throat (seek urgent help if this occurs)
  • Unusual taste in the mouth

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

In very rare cases, benzocaine has been associated with a serious condition called methaemoglobinaemia. This is a disorder in which the blood's ability to carry oxygen is reduced. It is more likely to occur if the product is used in excessive amounts or in people with certain pre-existing conditions. Symptoms can include pale, grey, or blue-coloured skin, lips, or fingernails, shortness of breath, rapid heart rate, and confusion. If you or someone else experiences any of these symptoms after using this spray, stop use immediately and call 999 or go to your nearest A&E department.

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

For mild side effects such as temporary numbness or tingling, no action is needed — these will resolve on their own. If you experience persistent irritation, an allergic reaction, or any of the serious symptoms described above, stop using the spray and seek medical advice promptly. You can report any suspected side effects to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. This helps regulators monitor the safety of medicines used in the UK.

Can Ultra Chloraseptic Throat Spray Interact With Other Medicines?

No clinically significant drug interactions are known for benzocaine throat spray at OTC doses. However, if you are taking any prescription medicines — particularly those that affect the blood or nervous system — it is always sensible to check with your pharmacist before using any new OTC product. People with a history of sensitivity to local anaesthetics should exercise particular caution and seek advice before use.

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