What Are Sodium Bicarbonate Ear Drops and How Do They Help?

 

Earwax — or cerumen, to use the clinical term — is completely normal. Your ears produce it to protect the ear canal from dust, bacteria, and debris. But sometimes wax builds up faster than it clears naturally, leading to a blocked, muffled feeling that can be genuinely uncomfortable. That's where sodium bicarbonate ear drops come in. KliarVax Sodium Bicarbonate Ear Drops 5% offer a simple, affordable way to soften hardened wax so it can drain away on its own or be removed more easily. At just £3.46 for a 10ml bottle, it's one of the most accessible earwax treatments available without a prescription. You can browse our full range of ear, nose, and throat products if you're looking for additional support.

Earwax blockage is one of the most common ear complaints seen in UK GP surgeries and pharmacies. The NHS notes that earwax usually falls out on its own, but when it doesn't, drops are often the first recommended step before considering ear irrigation.

 

How Do KliarVax Ear Drops Work to Soften Earwax?

 

The mechanism is straightforward but effective. Sodium bicarbonate is a mild alkaline compound. When introduced into the ear canal, it alters the local pH, which disrupts the structure of hardened wax and helps break it apart. Here's what happens step by step:

  • The alkaline solution contacts the outer surface of the wax plug.
  • It raises the pH of the ear canal environment, softening the wax matrix.
  • The wax becomes less viscous and begins to fragment.
  • Softened wax can then migrate naturally towards the outer ear or be removed by a clinician via irrigation.

It's a gentle process — no harsh chemicals, no syringing required in most cases. Just consistent use over a few days.

 

Who Is KliarVax Suitable For?

 

These drops are designed for adults and older children who are experiencing symptoms of earwax build-up. They're particularly useful if you regularly use hearing aids, earphones, or earplugs — all of which can push wax deeper into the canal. You might also find them helpful if you've been told by a nurse or GP that your ears need softening before irrigation.

KliarVax Sodium Bicarbonate Ear Drops 5% may be suitable for you if you experience:

  • A feeling of fullness or pressure in one or both ears
  • Muffled hearing or a slight reduction in sound clarity
  • Mild earache associated with wax build-up
  • Tinnitus (ringing in the ear) linked to wax blockage

 

How Do KliarVax Ear Drops Compare to Other Earwax Treatments?

 

Feature KliarVax Sodium Bicarbonate 5% Olive Oil Ear Drops
Active ingredient Sodium bicarbonate 5% Olive oil
Mechanism Alkaline pH disrupts wax structure Lubricates and softens wax
Speed of action Typically 3–5 days May take up to 2 weeks
OTC availability Yes Yes

 

Is KliarVax Safe to Store and Use at Home?

 

Yes — provided you follow the instructions carefully. Sodium bicarbonate ear drops should be stored below 25°C, away from direct sunlight, and kept out of reach of children. Once opened, check the product label for the in-use shelf life. Do not use the drops beyond the expiry date printed on the packaging.

It's worth noting that these drops are for external ear canal use only. Never insert anything into the ear canal to try to remove wax manually — this can push wax further in and cause injury. If you're managing other health conditions alongside ear care, you might also find our first aid range useful for general home health management.

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.

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

 

KliarVax Sodium Bicarbonate Ear Drops 5% is an over-the-counter cerumenolytic — a product specifically designed to soften and loosen earwax. The active ingredient, sodium bicarbonate at a 5% concentration, works as a mild alkaline agent that breaks down the lipid and protein structure of hardened wax. It is used to relieve the symptoms of earwax build-up, including blocked ears, muffled hearing, mild earache, and a sensation of pressure or fullness in the ear canal. The NHS recommends earwax softening drops as a first-line approach before considering ear irrigation or microsuction.

This product is for use in the ear canal only. It is not a treatment for ear infections, perforated eardrums, or any other ear condition beyond wax accumulation.

 

What Do You Need to Know Before Using KliarVax Ear Drops?

 

Before using these drops, it's important to check whether they are appropriate for your situation. Do not use KliarVax Sodium Bicarbonate Ear Drops if any of the following apply:

  • You have or suspect a perforated (burst) eardrum
  • You have an active ear infection (otitis externa or otitis media)
  • You have had ear surgery in the past 12 months
  • You have grommets (tympanostomy tubes) in place
  • You are allergic to sodium bicarbonate or any other ingredient in the formulation
  • You have severe or sudden hearing loss — seek urgent medical advice first

Regarding drug interactions, sodium bicarbonate ear drops act locally within the ear canal and are not absorbed systemically in meaningful amounts. As a result:

  • No significant drug interactions are currently known
  • If you use other ear drops, allow at least 15–30 minutes between applications and consult your pharmacist

 

How Should You Use KliarVax Sodium Bicarbonate Ear Drops?

 

Using ear drops correctly makes a real difference to how well they work. Follow these steps carefully each time you apply them:

  1. Wash your hands thoroughly before handling the bottle.
  2. Warm the bottle slightly by holding it 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. Gently pull the outer ear upward and backward to straighten the ear canal.
  5. Instil the recommended number of drops into the ear canal.
  6. Stay in the tilted position for 3–5 minutes to allow the drops to penetrate the wax.
  7. Place a small piece of cotton wool loosely at the ear opening if needed — do not push it in.
  8. Repeat in the other ear if required.
Indication Age Group Dose Frequency
Earwax softening Adults As directed on label Twice daily for up to 7 days
Earwax softening Older children As directed — seek pharmacist advice Twice daily, pharmacist guidance recommended

If symptoms do not improve after one week, stop use and consult your GP or pharmacist. You can also explore our wider ear, nose, and throat range for complementary products.

 

What Are the Possible Side Effects of KliarVax Ear Drops?

 

Side effects with sodium bicarbonate ear drops are uncommon, but it's worth knowing what to look out for.

Common side effects:

  • Mild, temporary stinging or tingling in the ear canal
  • A brief sensation of warmth inside the ear
  • Temporary feeling of fullness as wax softens and shifts

Less common side effects:

  • Skin irritation around the outer ear
  • Mild itching inside the ear canal
  • Transient dizziness if drops are applied cold

Stop using the drops and seek medical advice if you experience significant pain, discharge from the ear, sudden worsening of hearing, or any signs of an allergic reaction such as swelling or rash. If you're managing other minor health concerns alongside ear care, our pain relief range may also be of interest for associated discomfort.

 

How Should You Store KliarVax Sodium Bicarbonate Ear Drops?

 

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and heat sources
  • 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 label

Frequently Asked Questions

You can buy KliarVax Sodium Bicarbonate Ear Drops 5% directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £3.46. No prescription is needed as this is an over-the-counter product. Simply add it to your basket and it will be dispatched to your door.

How do sodium bicarbonate ear drops work in the ear?

Sodium bicarbonate is a mild alkaline compound that, when placed in the ear canal, raises the local pH and disrupts the structure of hardened earwax. This softens the wax so it can break apart and either drain naturally or be removed more easily by a healthcare professional. The process is gentle and does not involve any harsh chemicals.

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

Tilt your head to one side with the affected ear facing upward, then gently pull the outer ear upward and backward to open the canal. Instil the drops as directed, remain in position for 3–5 minutes, and repeat in the other ear if needed. Use twice daily for up to one week, or as advised by your pharmacist.

How long does it take for KliarVax ear drops to soften earwax?

Most people notice a difference within 3 to 5 days of consistent twice-daily use. The NHS recommends using earwax softening drops for several days before attempting irrigation or waiting for natural drainage. If there is no improvement after one week, consult your pharmacist or GP.

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

The dose should be as directed on the product label, typically applied twice daily into the affected ear. Always follow the instructions provided with the product and do not exceed the recommended frequency. If you are unsure about the correct dose for your situation, speak to a pharmacist before use.

Are KliarVax ear drops safe for children?

These drops may be suitable for older children, but you should always consult a pharmacist or GP before using them in younger children or toddlers. Young children's ear canals are more delicate, and professional guidance is important. Our baby and toddler range includes products specifically formulated for younger patients.

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

No — you should not use any ear drops, including sodium bicarbonate ear drops, if you have or suspect a perforated eardrum, unless a doctor has specifically told you it is safe to do so. Using drops with a perforated eardrum can cause pain, infection, or further damage. Always seek medical advice first if you are unsure about the condition of your eardrum.

What are the side effects of KliarVax Sodium Bicarbonate Ear Drops?

Side effects are uncommon but can include mild stinging, a temporary sensation of warmth, or a feeling of fullness in the ear as the wax softens. Less commonly, you may experience mild itching or skin irritation around the outer ear. If you develop significant pain, discharge, or sudden hearing changes, stop use immediately and contact your pharmacist or GP.

Who is eligible to use KliarVax Sodium Bicarbonate Ear Drops?

These drops are suitable for adults and older children experiencing symptoms of earwax build-up, such as blocked ears, muffled hearing, or mild earache. They are not suitable for people with perforated eardrums, active ear infections, grommets, or recent ear surgery. If you have any underlying ear conditions, speak to your GP or pharmacist before use.

What happens if I use too many drops or use them too often?

Using more drops than recommended or applying them more frequently than advised is unlikely to cause serious harm, but it may increase the risk of irritation inside the ear canal. Stick to the dosage instructions on the label and do not use the drops for longer than one week without seeking pharmacist advice. If you accidentally use a large amount, contact your pharmacist for guidance.

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

KliarVax Sodium Bicarbonate Ear Drops should be used for a maximum of one week at a time without further review from a pharmacist or GP. Prolonged or repeated use without professional assessment is not recommended. If your symptoms persist beyond one week, your GP may refer you for ear irrigation or microsuction.

What are the alternatives to sodium bicarbonate ear drops for earwax removal?

Common alternatives include olive oil ear drops, almond oil drops, and proprietary cerumenolytic preparations such as those containing urea hydrogen peroxide. The NHS notes that all of these can be effective at softening wax, though they may take slightly longer to work than sodium bicarbonate. Your pharmacist can help you choose the most appropriate option for your needs.

Can I use KliarVax ear drops before ear irrigation or microsuction?

Yes — in fact, using earwax softening drops for several days before ear irrigation or microsuction is often recommended by healthcare professionals to make the procedure easier and more comfortable. The NHS advises softening drops as a preparatory step before irrigation. Always inform the clinician performing the procedure that you have been using drops beforehand.

Do KliarVax ear drops interact with any other medicines?

Sodium bicarbonate ear drops act locally within the ear canal and are not absorbed into the bloodstream in significant amounts, so no systemic drug interactions are currently known. If you are using other ear drops at the same time, allow at least 15–30 minutes between applications and check with your pharmacist. You can also browse our ear, nose, and throat collection for compatible products.

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

Current NHS guidance recommends earwax softening drops — including sodium bicarbonate, olive oil, and almond oil — as the first-line self-care approach for earwax build-up before considering clinical removal methods. NICE guidance supports the use of cerumenolytic drops to facilitate wax removal and reduce the need for irrigation. Regular use of cotton buds is discouraged as it can push wax deeper into the canal.

How Should You Use KliarVax Sodium Bicarbonate Ear Drops?

Using ear drops correctly is just as important as using the right product. Before you begin, wash your hands thoroughly. Warming the bottle in your hands for a minute or two before application helps prevent dizziness, which can occur if cold liquid enters the ear canal.

Follow these steps each time you apply the drops:

Never insert cotton buds, fingers, or any other object into the ear canal. This can push wax deeper and cause injury to the delicate structures inside the ear.

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

Always follow the dosage instructions printed on the product label. The table below provides a general guide, but your pharmacist can advise on the most appropriate dose for your individual circumstances.

Do not use more drops than recommended in the hope of faster results. Overuse can cause unnecessary irritation to the ear canal lining.

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

There is no single "best" time of day, but many people find it easiest to apply ear drops in the morning and again in the evening — for example, after waking and before bed. Applying them at consistent times each day helps you build a routine and ensures the drops have adequate time to work between applications.

Applying the drops before bed can be particularly convenient, as lying still for a few minutes after application is easier at night. Just make sure you warm the bottle first to avoid any dizziness from cold drops.

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

KliarVax Sodium Bicarbonate Ear Drops should be used for a maximum of one week at a time. In most cases, earwax will soften and begin to clear within 3 to 5 days of regular use. If your symptoms have not improved after seven days of consistent use, stop the drops and consult your GP or pharmacist — you may need ear irrigation or microsuction.

Do not use these drops continuously over long periods without professional review. Repeated courses should only be undertaken on the advice of a healthcare professional.

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

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

Most people tolerate sodium bicarbonate ear drops well, and side effects are generally mild and short-lived. They tend to occur at the start of treatment as the ear canal adjusts to the drops.

  • Mild stinging or tingling sensation in the ear canal immediately after application
  • A brief feeling of warmth inside the ear
  • A temporary sensation of fullness or pressure as the wax begins to soften and shift

These effects usually resolve within a few minutes of application and are not a reason to stop treatment unless they are severe or persistent.

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

Less frequently, some people may experience the following. These are not dangerous in most cases, but you should monitor them and seek advice if they worsen.

  • Mild itching inside the ear canal
  • Skin irritation or redness around the outer ear
  • Transient dizziness, particularly if the drops are applied cold
  • A temporary increase in the sensation of blocked ears as wax loosens

Warming the bottle in your hands before use can help reduce the risk of dizziness. If itching or irritation persists, stop using the drops and consult your pharmacist.

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

Serious side effects are rare with this product when used as directed. However, you should stop use immediately and seek medical attention if you experience any of the following:

  • Significant or worsening pain inside the ear
  • Discharge from the ear (particularly if it is yellow, green, or blood-stained)
  • Sudden or significant worsening of hearing
  • Signs of an allergic reaction, such as swelling of the face, lips, or throat, or a skin rash

These symptoms may indicate an underlying ear infection, a perforated eardrum, or an allergic response — all of which require prompt professional assessment.

What Should You Do If You Experience Side Effects?

If you experience mild side effects such as brief stinging or warmth, you can usually continue using the drops and monitor how you feel. Try warming the bottle before use and ensure you are applying the drops correctly. If side effects are persistent, uncomfortable, or worsening, stop use and speak to your pharmacist or GP as soon as possible.

You can also report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. This helps improve the safety monitoring of medicines available in the UK.

Can KliarVax Sodium Bicarbonate Ear Drops Interact With Other Medicines?

Because sodium bicarbonate ear drops act locally within the ear canal and are not absorbed into the bloodstream in clinically significant amounts, no systemic drug interactions are currently known. However, if you are using other ear drops concurrently — for example, antibiotic ear drops prescribed by your GP — you should allow at least 15 to 30 minutes between applications and seek pharmacist advice to ensure compatibility.

Always inform your pharmacist of all medicines you are currently taking, including over-the-counter products, before starting a new treatment.

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