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 discomfort is hard to ignore. Ultra Chloraseptic Anaesthetic Throat Spray Blackcurrant 15ml is a targeted, fast-acting throat spray for sore throat relief, available over the counter without a prescription. It delivers benzocaine — a well-established local anaesthetic — directly to the affected area, helping to numb pain quickly so you can get on with your day. You can find it alongside other ear, nose, and throat remedies at Cured Pharmacy.

Sore throats are one of the most common reasons people visit a pharmacist in the UK. Most cases are caused by viral infections and resolve on their own within a week, but the discomfort in the meantime can be significant. This spray offers a practical, non-systemic option for managing that pain while your body heals.

 

How Does Ultra Chloraseptic Throat Spray Work?

 

The active ingredient is benzocaine 0.71% w/v. Benzocaine is a local anaesthetic from the ester class. It works by temporarily blocking sodium channels in the nerve endings of the throat's mucosal lining, which interrupts the transmission of pain signals to the brain. The result? A localised numbing effect that kicks in within minutes of application.

  • Benzocaine binds to voltage-gated sodium channels in sensory nerve fibres
  • Sodium ion influx is blocked, preventing nerve depolarisation
  • Pain signals cannot travel to the brain from the affected tissue
  • The effect is localised — it does not enter the bloodstream at therapeutic OTC doses
  • Relief typically lasts for a short period, allowing repeated dosing throughout the day

Because the action is local rather than systemic, it avoids the gastrointestinal effects sometimes associated with oral analgesics like ibuprofen. That said, it treats the symptom rather than the underlying cause, so it works best as part of a broader approach to managing a sore throat.

 

Who Should Use Ultra Chloraseptic Throat Spray?

 

This spray is suitable for adults and children aged 6 years and over who are experiencing mild to moderate sore throat pain. It is particularly useful when you need fast, targeted relief without taking oral tablets — for example, if you have difficulty swallowing pills or prefer not to use systemic pain relief.

  • Adults with a sore throat caused by a cold, flu, or minor infection
  • Children aged 6 and over (under adult supervision)
  • People who prefer a non-oral route for pain relief
  • Those looking for a convenient, portable throat spray for sore throat symptoms

It is not suitable for children under 6, or for anyone with a known allergy to benzocaine or other ester-type local anaesthetics. If you are pregnant or breastfeeding, speak to your pharmacist or GP before use.

 

How Does Ultra Chloraseptic Compare to Throat Lozenges?

 

Feature Ultra Chloraseptic Throat Spray Throat Lozenges (e.g. Strepsils)
Active ingredient Benzocaine 0.71% w/v Varies (e.g. amylmetacresol, lidocaine)
Onset of action Within minutes of spraying Gradual as lozenge dissolves
Suitable for children Age 6 and over Varies by product (often 12+)
Route Direct oropharyngeal spray Oral (dissolved in mouth)

 

How Should You Store Ultra Chloraseptic Throat Spray?

 

Store the spray below 25°C, away from direct sunlight and heat sources. Keep the cap on when not in use to prevent contamination of the nozzle. As with all medicines, keep it out of the reach and sight of children. Do not use after the expiry date printed on the packaging.

If you are managing multiple symptoms alongside a sore throat — such as pain elsewhere in the body — you might also want to explore our pain relief range for complementary options. Always check with your pharmacist before combining products.

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 Ultra Chloraseptic Anaesthetic Throat Spray Blackcurrant 15ml

 

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

 

Ultra Chloraseptic Anaesthetic Throat Spray Blackcurrant 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 as its active ingredient — a local anaesthetic that temporarily numbs the throat lining. It is used for symptomatic relief only and does not treat the underlying cause of a sore throat, whether viral or bacterial. The blackcurrant flavour makes it more palatable, particularly for older children using it under adult supervision.

Sore throats are extremely common and are most often caused by viral upper respiratory tract infections. According to NHS guidance, most sore throats clear up on their own within a week. This spray helps manage discomfort in the meantime, making it easier to eat, drink, and speak.

Common side effects:

  • Altered taste sensation

Less common side effects:

Stop using the spray immediately and seek urgent medical attention if you notice bluish discolouration of the lips or fingernails, shortness of breath, or rapid heart rate. These could be signs of methaemoglobinaemia.

How does Ultra Chloraseptic Throat Spray work in the body?

The spray contains benzocaine 0.71% w/v, which is a local anaesthetic. It works by blocking sodium channels in the nerve endings of the throat lining, preventing pain signals from reaching the brain. The action is entirely localised — it does not enter the bloodstream at normal 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 once to release a single spray. Allow the spray to coat the throat briefly before swallowing. Repeat every two hours as needed, up to a maximum of six times in 24 hours.

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

Adults should use one spray directed to the back of the throat every two hours as needed. Do not exceed six sprays in any 24-hour period. If symptoms persist beyond three days, consult your pharmacist or GP.

Can children use Ultra Chloraseptic Throat Spray?

Yes, children aged 6 and over can use this spray under adult supervision, using the same dose as adults — one spray every two hours, up to six times daily. It must not be used in children under 6 years of age. Always supervise use in younger children to ensure correct application.

What are the side effects of Ultra Chloraseptic Throat Spray?

Most people tolerate this spray well. Possible side effects include temporary numbness beyond the throat, mild local irritation, or altered taste. In rare cases, hypersensitivity reactions or methaemoglobinaemia may occur — stop use immediately and seek medical help if you notice bluish lips or difficulty breathing.

Who should not use Ultra Chloraseptic Throat Spray?

Do not use this spray if you are allergic to benzocaine or any ester-type local anaesthetic. It is also not suitable for children under 6 years old. If you are pregnant, breastfeeding, or have a history of methaemoglobinaemia, speak to your GP or pharmacist 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, or if it is getting worse, you should stop using the spray and consult your GP. Prolonged use without medical review is not recommended.

Is Ultra Chloraseptic Throat Spray a throat spray for sore throat caused by tonsillitis?

This spray can help relieve the pain associated with tonsillitis, but it does not treat the underlying infection. If tonsillitis is caused by bacteria, your GP may prescribe antibiotics. Use this spray as a throat spray for sore throat symptom relief while awaiting or alongside medical treatment.

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

Exceeding the recommended dose increases the risk of side effects, including the rare but serious risk of methaemoglobinaemia. If you accidentally use more than directed, contact NHS 111 or your nearest pharmacist for advice. Do not use more than six sprays in 24 hours.

What are alternatives to Ultra Chloraseptic Throat Spray?

Alternatives include throat lozenges containing benzocaine or lidocaine, antiseptic lozenges such as Strepsils, or systemic pain relief such as ibuprofen or paracetamol. You can also explore our cold and flu range for products that address multiple symptoms at once. Your pharmacist can advise on the most suitable option for your situation.

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

If you are pregnant, you should speak to your GP or pharmacist before using this spray. While benzocaine is applied locally, it is always advisable to seek professional guidance before using any medicine during pregnancy. Your pharmacist can suggest the safest options for sore throat relief during pregnancy.

Does Ultra Chloraseptic Throat Spray interact with other medicines?

No clinically significant drug interactions are known at OTC doses. However, if you are taking prescribed medicines — particularly those affecting the cardiovascular or nervous system — it is always sensible to check with your pharmacist before adding any new product. You can also browse our pain relief collection if you need additional symptom management.

What is the best time to use Ultra Chloraseptic Throat Spray?

Use the spray whenever sore throat pain is most troublesome — many people find it particularly helpful before meals to make eating and drinking more comfortable. You can also use it before bed if throat pain is disrupting sleep. Space doses at least two hours apart and do not exceed six sprays in 24 hours.

What does the latest research say about benzocaine throat sprays?

Benzocaine has been used as a local anaesthetic for decades and its efficacy for oropharyngeal pain relief is well established in clinical literature. Regulatory bodies including the MHRA continue to approve benzocaine-containing products for OTC use at appropriate concentrations. Current guidance recommends using the lowest effective dose for the shortest necessary duration.

How Should You Use Ultra Chloraseptic Throat Spray?

Using this spray correctly is straightforward, but it is worth taking a moment to get the technique right. Directing the spray accurately to the back of the throat ensures the benzocaine reaches the affected area and provides the most effective relief.

Follow these steps each time you use the spray:

Do not inhale the spray. If you accidentally spray into your eyes, rinse thoroughly with water and seek medical advice if irritation persists.

What Is the Correct Dose of Ultra Chloraseptic Throat Spray?

The dose is the same for adults and children aged 6 and over — one spray per dose, repeated every two hours as needed. Never exceed six doses in any 24-hour period, regardless of age. 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?

There is no fixed schedule — use the spray when your sore throat pain is most bothersome. Many people find it particularly helpful before meals, as numbing the throat briefly can make eating and drinking significantly more comfortable. Using it before bed may also help if throat pain is keeping you awake.

Space each dose at least two hours apart. If you find yourself needing it more frequently than every two hours, this may indicate your symptoms are worsening and you should seek advice from a pharmacist or GP.

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 seven days, and you should only need the spray for a few days at most. If your symptoms have not improved after three days of use, or if they are getting worse rather than better, stop using the spray and consult your GP.

Prolonged use without medical review is not recommended. A persistent sore throat may indicate a bacterial infection requiring antibiotics, or another condition that needs professional assessment.

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?

Most people who use this spray do not experience significant side effects. Because benzocaine acts locally rather than systemically, the risk of widespread adverse effects is low at the recommended OTC dose. That said, some people do notice mild effects at or near the site of application.

  • Temporary numbness or tingling in the mouth, tongue, or lips
  • Mild local irritation or a burning sensation in the throat
  • Altered or reduced taste sensation shortly after use

These effects are generally short-lived and resolve on their own as the benzocaine wears off. They are not usually a reason to stop using the spray unless they are particularly bothersome.

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

Less commonly, some individuals may experience reactions that go beyond mild local effects. These are more likely in people with sensitivities to local anaesthetics or related compounds.

  • Hypersensitivity or allergic reactions, including skin rash, itching, or hives
  • Swelling of the mouth, lips, or throat (angioedema)
  • Contact dermatitis in or around the oral cavity
  • Nausea if a significant amount is swallowed

If you notice any of these reactions, stop using the spray immediately and seek advice from your pharmacist or GP.

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

A rare but serious risk associated with benzocaine-containing products is methaemoglobinaemia — a condition in which the blood's ability to carry oxygen is reduced. This is most likely to occur with excessive use or in individuals with certain genetic enzyme deficiencies. It has been reported more frequently in young children, which is one reason this spray is not suitable for those under 6 years of age.

Seek emergency medical attention immediately if you or someone else experiences any of the following after using this spray:

  • Bluish or greyish discolouration of the lips, fingernails, or skin (cyanosis)
  • Shortness of breath or difficulty breathing
  • Rapid or irregular heartbeat
  • Dizziness, confusion, or loss of consciousness
  • Extreme fatigue or weakness

What Should You Do If You Experience Side Effects?

For mild side effects such as temporary numbness or taste changes, no action is usually needed — simply wait for the effect to pass. If you experience an allergic reaction or any of the serious symptoms listed above, stop using the spray immediately and contact NHS 111, your GP, or go to your nearest A&E department.

You can also report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. Reporting helps improve the safety information available for all medicines.

Can Ultra Chloraseptic Throat Spray Interact With Other Medicines?

No clinically significant drug interactions have been identified for benzocaine at OTC doses when used as directed. Because the active ingredient acts locally and is not significantly absorbed into the bloodstream, the risk of systemic interactions is very low. However, if you are taking any prescribed medicines — particularly those affecting the cardiovascular or nervous system — it is always worth checking with your pharmacist before use.

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