Removal of earwax

Ear drops

Earwax is naturally produced by your body to protect the skin inside your ear canal. The quantity produced varies between individuals, and sometimes it can build up and become hard and dry, causing hearing problems. Sodium bicarbonate ear drops are used to soften dry and hardened earwax. This reduces the need for wax to be physically removed, but also makes ear irrigation and micro-suction easier when removal is necessary.

You can buy sodium bicarbonate ear drops from pharmacies.

To make sure this is the right treatment for you, before you start using the drops it is important that you speak with a doctor or pharmacist:

  • If you have a burst (perforated) eardrum, or if you have recently had any ear surgery.

  • If you have ever had an allergic reaction to any other ear drops.

  • If you are using any other ear products. This includes any preparations which are available to buy without a prescription, as well as herbal and complementary medicines.

Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about using the drops.

  1. Wash your hands before you begin.

  2. Warm the drops to room temperature before using them. (Let the bottle stand in the room for about half an hour.)

  3. Lie down, or tilt your head a little, so that the affected ear is facing upwards.

  4. Gently pull your earlobe to straighten the ear canal.

  5. Release 3-4 drops into your ear to fill the ear canal. Try not to touch the inside of your ear with the dropper as you do this. If the drops are for a child, only insert as many drops as are needed to fill the ear canal.

  6. Keep your ear facing upwards for 5-10 minutes to keep the solution in your ear.

  7. Repeat the process in your other ear if you have been asked to use the drops in both ears.

  • Use the drops twice a day for 3-5 days. This is usually sufficient to soften the wax, but if your symptoms do not improve, make an appointment to see your doctor for further advice.

  • Do not try to clean inside your ear with cotton buds. If you stick buds or other objects into your ear they can compact the wax and make matters worse. Just wipe the outside of your ear with a clean cloth or tissue if any wax comes out on its own. Flakes or crusts of earwax often fall out bit by bit. You may not notice the wax as it comes out of your ear.

Sodium bicarbonate ear drops can sometimes cause dryness in your ear canal, but this is rarely troublesome. It is unlikely that you will experience any other side-effects but speak with your doctor or pharmacist if there is anything that concerns you.

  • Gardez tous les médicaments hors de la portée et de la vue des enfants.

  • Conserver dans un endroit frais et sec, à l'abri de la chaleur et de la lumière directes.

  • If there is any preparation left in the container after you have finished your course of treatment, do not keep it to use later. Ear drops should not be used if the bottle has been open for longer than four weeks.

Questions fréquemment posées

How long do I need to use the ear drops for before I see an improvement?

You should use the drops twice a day for 3-5 days. This is generally enough to soften the wax. If your symptoms haven't improved after this time, you should consult your doctor for further guidance.

Is it normal for my ear to feel dry after using these ear drops?

Yes, sodium bicarbonate ear drops can sometimes lead to dryness in your ear canal. This is usually not a significant problem. If you have any other concerns, speak with your doctor or pharmacist.

When should I avoid using sodium bicarbonate ear drops?

You should speak with a doctor or pharmacist before using these drops if you have a burst eardrum, or have recently had ear surgery. Also, if you've had an allergic reaction to any other ear drops in the past, or are currently using other ear products, including non-prescription, herbal, or complementary medicines, you should consult them first.

What should I do if I accidentally get the ear drops in my other ear, or if I'm only supposed to treat one ear?

The instructions advise repeating the process in your other ear if you have been asked to use the drops in both ears. If you are only treating one ear, focus on applying the drops only to the affected ear as instructed by your doctor or pharmacist.

After the wax softens, how will it come out of my ear?

Flakes or crusts of earwax often fall out bit by bit on their own, and you might not even notice them coming out. Do not use cotton buds or other objects to try and clean inside your ear, as this can push the wax further in and make the problem worse. Simply wipe the outside of your ear with a clean cloth or tissue if any wax becomes visible.

Can I store unused ear drops for future use?

It's best not to keep any leftover preparation in the container once you've completed your course of treatment. Ear drops should not be used if the bottle has been open for longer than four weeks. Dispose of any out-of-date or unwanted medicines by taking them to your local pharmacy.
