What Are Sodium Bicarbonate Ear Drops?

 

Blocked ears are frustrating. Whether it's a dull muffled sound, a sense of fullness, or just that nagging feeling that something isn't quite right, ear wax build-up is one of the most common causes. Sodium bicarbonate ear drops offer a simple, clinically recognised way to soften hardened wax so your ears can clear more easily — without the need for a GP appointment. Care Sodium Bicarbonate Ear Drops 10ml are available over the counter and are a trusted first-line option recommended by NHS guidance for ear wax management. You can find them alongside other ear, nose, and throat products in our Ear, Nose & Throat collection.

Each 10ml bottle contains a 5% w/v solution of sodium bicarbonate in water. It's a straightforward formulation — no unnecessary additives, no complicated instructions. Just a gentle, effective way to tackle ear wax at home.

 

How Do Care Sodium Bicarbonate Ear Drops Work?

 

Ear wax (cerumen) is produced naturally by glands in the outer ear canal. It's actually protective — trapping dust, debris, and bacteria. But sometimes it builds up faster than it clears, leading to blockage. So how do these drops help?

  • Sodium bicarbonate raises the pH of the ear canal environment.
  • This alkaline shift breaks down the lipid and protein structure of hardened wax.
  • The wax softens and becomes less adherent to the canal walls.
  • Once softened, wax can migrate out naturally or be removed more easily during ear irrigation (syringing).

The NHS recommends using ear drops such as sodium bicarbonate solution to soften wax before attempting any form of ear irrigation. Using drops alone for several days is often enough to resolve mild to moderate blockages without any further intervention.

 

Who Should Use Care Sodium Bicarbonate Ear Drops?

 

These drops are suitable for most adults and children over 12 years who are experiencing symptoms of ear wax build-up. If you're unsure whether wax is the cause of your symptoms, it's worth speaking to a pharmacist before starting treatment.

  • Adults with symptoms of ear wax blockage (muffled hearing, ear fullness, mild earache)
  • People preparing for ear irrigation or microsuction at a clinic
  • Those who have been advised by their GP or nurse to use ear wax softening drops
  • Individuals who use hearing aids or earphones regularly, as these can accelerate wax build-up

 

How Do Sodium Bicarbonate Ear Drops Compare to Olive Oil Drops?

 

Feature Care Sodium Bicarbonate Ear Drops Olive Oil Ear Drops
Active ingredient Sodium bicarbonate 5% w/v Olive oil
Mechanism Alkaline pH breaks down wax structure Lubricates and softens wax
NHS recommended? Yes Yes
Suitable before irrigation? Yes Yes

 

Is Care Sodium Bicarbonate Ear Drops Suitable for Everyone?

 

Not quite. While sodium bicarbonate ear drops are safe for most people, there are some important exceptions. Do not use these drops if you have a perforated eardrum, an active ear infection, grommets in place, or if you have had recent ear surgery. If you experience pain, discharge, or sudden hearing loss, stop use immediately and consult your GP. These symptoms may indicate a condition that requires medical assessment rather than self-treatment.

It's also worth noting that if you wear hearing aids, you should remove them before applying the drops and wait until the ear is dry before reinserting. For general ear health queries or if you're managing other conditions alongside ear wax, our First Aid collection includes a range of products to support everyday health needs.

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 Care Sodium Bicarbonate Ear Drops 10ml

 

What Is Care Sodium Bicarbonate Ear Drops and What Is It Used For?

 

Care Sodium Bicarbonate Ear Drops 10ml is an over-the-counter ear care product used to soften and loosen hardened ear wax. The active ingredient, sodium bicarbonate 5% w/v, is a well-established cerumenolytic agent — meaning it helps break down the composition of ear wax so it can clear from the ear canal more easily. The NHS recognises ear wax softening drops as a first-line approach before considering ear irrigation or microsuction.

You might use these drops if you're experiencing muffled hearing, a sensation of fullness in the ear, mild discomfort, or if your GP or practice nurse has recommended softening drops ahead of a wax removal appointment. They are not a treatment for ear infections, tinnitus, or hearing loss caused by other conditions.

 

What Do You Need to Know Before Using Care Sodium Bicarbonate Ear Drops?

 

Before using these drops, check the following contraindications carefully:

  • Do not use if you have a perforated (burst) eardrum
  • Do not use if you have an active ear infection (otitis externa or otitis media)
  • Do not use if you have grommets or other ear tubes in place
  • Do not use if you have had recent ear surgery
  • Do not use in children under 12 years without medical advice
  • Avoid contact with eyes

There are no known significant drug interactions with topical sodium bicarbonate ear drops. However, if you are using other ear drops concurrently, allow at least 15 minutes between applications and seek pharmacist advice.

  • No clinically significant interactions with systemic medicines have been identified for topical otic use

 

How Should You Use Care Sodium Bicarbonate Ear Drops?

 

  1. Wash your hands thoroughly before use.
  2. Gently warm the bottle in your hands for a minute or two — cold drops can cause dizziness.
  3. Tilt your head to one side so the affected ear faces upward.
  4. Carefully instil the drops into the ear canal as directed.
  5. Remain in this position for 2–3 minutes to allow the drops to penetrate the wax.
  6. Place a small piece of cotton wool loosely at the ear opening to absorb any excess.
  7. Repeat for the other ear if required.
  8. Use twice daily for up to 5 days, or as directed by your pharmacist or GP.
Indication Age Group Dose Frequency
Ear wax softening Adults & children over 12 As directed on pack Twice daily, up to 5 days
Pre-irrigation preparation Adults As directed on pack Twice daily for 3–5 days before appointment

If you're managing ear health alongside other conditions, it may be worth exploring our Allergy and Hay Fever collection, as allergic rhinitis can sometimes contribute to ear congestion and wax build-up.

 

What Are the Possible Side Effects of Care Sodium Bicarbonate Ear Drops?

 

Side effects from sodium bicarbonate ear drops are uncommon when used as directed. Most people tolerate them well. However, as with any medicine, some individuals may experience reactions.

Common side effects:

  • Mild, temporary stinging or tingling in the ear canal
  • Sensation of increased ear fullness immediately after application (this usually resolves quickly)

Less common side effects:

  • Localised skin irritation around the ear opening
  • Dizziness if drops are applied too cold
  • Temporary worsening of muffled hearing as wax softens and shifts

Stop using the drops and seek medical advice if you experience ear pain, discharge, bleeding, or sudden significant hearing loss. These may indicate an underlying condition requiring assessment.

 

How Should You Store Care Sodium Bicarbonate Ear Drops?

 

  • Store below 25°C in a cool, dry place
  • Keep out of direct sunlight
  • Keep the bottle tightly closed when not in use
  • Keep out of the reach and sight of children
  • Do not use after the expiry date printed on the bottle
  • Discard any remaining solution 28 days after opening
  • Do not store in the bathroom or near a heat source

Frequently Asked Questions

Where can I buy sodium bicarbonate ear drops online in the UK?

You can buy Care Sodium Bicarbonate Ear Drops 10ml directly from Cured Pharmacy, a UK GPhC-registered online pharmacy. No prescription is needed as these are a General Sale List (GSL) medicine. They are available for just £3.49 with convenient online ordering and delivery to your door.

How do sodium bicarbonate ear drops work in the ear?

Sodium bicarbonate creates an alkaline environment in the ear canal, which disrupts the structure of hardened ear wax. This softening effect allows the wax to break apart and either migrate out naturally or be removed more easily during ear irrigation. It's a well-established mechanism supported by NHS guidance on ear wax management.

How do I use Care Sodium Bicarbonate Ear Drops step by step?

Warm the bottle in your hands, tilt your head so the affected ear faces upward, and instil the drops into the ear canal. Stay in that position for 2–3 minutes, then place a small piece of cotton wool loosely at the ear opening. Use twice daily for up to 5 days, or as directed by your pharmacist.

How long does it take for sodium bicarbonate ear drops to clear ear wax?

Most people notice an improvement within 3 to 5 days of twice-daily use. In some cases, particularly with very hard or impacted wax, it may take the full 5-day course before the wax softens sufficiently. If there is no improvement after 5 days, consult your GP or pharmacist — you may need ear irrigation or microsuction.

What is the correct dose of Care Sodium Bicarbonate Ear Drops?

Use the drops twice daily as directed on the product packaging. The drops should be applied to the affected ear or ears, and you should remain still for a few minutes after application to allow the solution to work. Do not exceed the recommended duration of use without seeking medical advice.

Can children use Care Sodium Bicarbonate Ear Drops?

These drops are generally suitable for adults and children aged 12 years and over. For children under 12, you should always consult a GP or pharmacist before use, as ear wax management in younger children may require a different approach. Never attempt ear irrigation in young children without professional guidance.

Are there any side effects of sodium bicarbonate ear drops?

Side effects are uncommon but can include a mild stinging or tingling sensation in the ear canal after application. Some people notice a temporary feeling of increased fullness as the wax softens and shifts. If you experience pain, discharge, or sudden hearing loss, stop use immediately and seek medical advice.

Can I use these ear drops if I have a perforated eardrum?

No — you must not use sodium bicarbonate ear drops if you have a perforated eardrum or suspect one. Introducing any liquid into the middle ear through a perforation can cause serious complications including infection. Always check with your GP if you are unsure about the condition of your eardrum before using any ear drops.

What are the alternatives to sodium bicarbonate ear drops for ear wax?

The main alternatives are olive oil ear drops and almond oil ear drops, both of which are also recommended by the NHS for softening ear wax. Sodium bicarbonate drops may work slightly faster due to their chemical action, whereas oil-based drops work by lubricating the wax. Your pharmacist can help you choose the most suitable option — you can browse related products in our Ear, Nose & Throat collection.

How long can I use Care Sodium Bicarbonate Ear Drops for?

These drops should be used for a maximum of 5 consecutive days unless directed otherwise by a healthcare professional. Prolonged use beyond this without medical advice is not recommended. If your symptoms persist after 5 days, speak to your GP or pharmacist about further assessment or treatment options.

Can I use sodium bicarbonate ear drops before ear syringing?

Yes — in fact, this is one of the most common reasons people use them. The NHS recommends using ear wax softening drops for several days before ear irrigation to make the procedure more effective and comfortable. Your GP surgery or ear care clinic may specifically advise you to use drops in the days leading up to your appointment.

What happens if I miss a dose of Care Sodium Bicarbonate Ear Drops?

If you miss an application, simply continue with your next scheduled dose — do not double up to compensate. Consistency helps, but missing one application is unlikely to significantly affect the outcome. Just carry on with the twice-daily routine until you complete the course.

Who is eligible to use Care Sodium Bicarbonate Ear Drops?

These drops are suitable for adults and young people aged 12 and over who have symptoms of ear wax build-up and no contraindications such as a perforated eardrum, active ear infection, or grommets. They are available without a prescription. If you have any doubt about your suitability, a pharmacist can advise you quickly and easily.

Do sodium bicarbonate ear drops interact with other medicines?

No clinically significant interactions between topical sodium bicarbonate ear drops and systemic medicines have been identified. If you are using other ear drops at the same time, leave at least 15 minutes between applications. Always mention all medicines you are taking to your pharmacist if you have any concerns.

What is the latest guidance on using ear drops for ear wax removal?

Current NHS guidance recommends ear wax softening drops — including sodium bicarbonate solution — as the first step in managing ear wax build-up at home. NICE guidance also supports the use of cerumenolytic drops before ear irrigation. For general wellbeing products to complement your ear care routine, take a look at our Vitamins and Supplements collection.

How Should You Use Care Sodium Bicarbonate Ear Drops?

Using these drops correctly makes a real difference to how well they work. Always read the label before use, and follow these steps carefully to get the most from your treatment.

What Is the Correct Dose of Care Sodium Bicarbonate Ear Drops?

The dose is straightforward and the same for all adult users. Always follow the instructions on the product label, and do not use more frequently than recommended without speaking to a pharmacist or GP first.

When Is the Best Time to Use Care Sodium Bicarbonate Ear Drops?

There is no strict requirement to use these drops at a specific time of day, but many people find it easiest to apply them in the morning and again in the evening — for example, after breakfast and before bed. Applying them at night can be particularly convenient, as lying still for a few minutes is easier when you're winding down. Avoid using the drops immediately before activities where you need clear hearing, as the wax may temporarily shift during treatment.

If you wear hearing aids, always remove them before applying the drops and wait until the ear canal is fully dry before reinserting.

How Long Can You Use Care Sodium Bicarbonate Ear Drops For?

Use these drops for a maximum of 5 consecutive days. For most people, this is sufficient to soften the wax enough for it to clear naturally or to prepare the ear for irrigation. If your symptoms have not improved after 5 days, do not continue using the drops without seeking advice from your GP or pharmacist — persistent symptoms may indicate a more significant blockage or an underlying condition that needs professional assessment.

Once opened, discard any remaining solution after 28 days, even if the bottle is not empty.

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

What Are the Most Common Side Effects of Care Sodium Bicarbonate Ear Drops?

Care Sodium Bicarbonate Ear Drops are generally well tolerated when used as directed. Most people complete a course without experiencing any notable side effects. That said, it's important to know what to look out for.

  • Mild stinging or tingling sensation in the ear canal immediately after application
  • Temporary feeling of increased ear fullness as the wax softens and moves
  • Brief sensation of muffled hearing during the treatment period

These effects are usually short-lived and resolve on their own within a few minutes of application. They are not a reason to stop treatment unless they are severe or persistent.

What Are the Less Common Side Effects of Care Sodium Bicarbonate Ear Drops?

Less commonly, some individuals may experience reactions that are slightly more noticeable, particularly if they have sensitive skin around the ear or if the drops are applied incorrectly.

  • Localised skin irritation or redness around the outer ear opening
  • Dizziness or a brief spinning sensation, usually caused by applying cold drops
  • Itching inside the ear canal
  • Temporary worsening of hearing as softened wax shifts position within the canal

Warming the bottle in your hands before use can help reduce the risk of dizziness. If irritation around the ear persists, discontinue use and consult your pharmacist.

What Are the Serious Side Effects of Care Sodium Bicarbonate Ear Drops?

Serious side effects are rare with this product when used correctly. However, certain symptoms should prompt you to stop using the drops immediately and seek medical attention. These include ear pain that worsens during or after use, discharge or fluid coming from the ear, bleeding from the ear canal, or a sudden and significant drop in hearing. These symptoms may suggest a perforated eardrum, an ear infection, or another condition that requires professional assessment rather than self-treatment.

What Should You Do If You Experience Side Effects?

For mild side effects such as brief stinging or temporary fullness, no action is usually needed — simply continue with the course as directed. If you experience persistent irritation, pain, or any of the serious symptoms listed above, stop using the drops straight away. Contact your pharmacist in the first instance, as they can assess whether you need to see a GP. In the event of a severe allergic reaction — which is extremely rare — seek emergency medical help immediately.

Can Care Sodium Bicarbonate Ear Drops Interact With Other Medicines?

No clinically significant interactions between topically applied sodium bicarbonate ear drops and systemic medicines have been identified. Because the drops act locally within the ear canal and are not absorbed into the bloodstream in meaningful amounts, the risk of systemic drug interactions is considered negligible. If you are using other ear drops at the same time — for example, antibiotic ear drops prescribed by your GP — leave at least 15 minutes between applications and seek pharmacist advice to ensure both products are used safely and effectively.

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