About clotrimazole for ear infections
Typ av medicin | An antifungal |
Används för | Fungal infections in the ear in otitis externa |
Även kallad | Canesten® Solution |
Tillgänglig som | Solution for use with a dropper |
Otitis externa is a term used for inflammation in the ear when it is confined to the ear canal and does not go further than the eardrum. If you get things like water, shampoo or soap in your ear then it can cause itching. If you then scratch or poke your ear, this can damage the skin in the ear canal and cause inflammation. Sometimes the inflamed skin becomes infected by germs such as bacteria or fungi. Clotrimazole solution is used to treat ear infections caused by fungi. It is available on prescription or you can buy it without a prescription at a pharmacy.
Before using clotrimazole for ear infections
Tillbaka till innehållTo make sure this is the right treatment for you, before you start using clotrimazole solution in your ear, make sure your doctor or pharmacist knows:
If you are pregnant or breastfeeding. Although clotrimazole is not known to be harmful to babies, you should only use medicines on the recommendation of a doctor while you are expecting or breastfeeding a baby.
Om du någonsin har haft en allergisk reaktion mot en medicin.
If you are using any other drops or remedies in your ears.

How to use clotrimazole solution as ear drops
Tillbaka till innehållWash your hands. Clean your ear gently with warm water and then pat it dry.
Lie down, or tilt your head a little, so that the affected ear is facing upwards.
Gently pull your earlobe downwards to straighten the ear canal.
Hold the dropper from the bottle near to your ear and apply enough pressure to release two or three drops of solution into your ear.
Keep your ear facing upwards for a few minutes to allow the solution to come into contact with the affected area.
Repeat the process in your other ear if both ears are affected.
Replace the bottle dropper.

Tillbaka till innehållBefore you use the drops, read the manufacturer's printed information leaflet from the pack. It will give you more information about clotrimazole and will provide you with a full list of any side-effects which you could experience.
Use the ear drops exactly as your doctor tells you to. Unless you have been told otherwise, put two to three drops into the affected ear(s) two or three times a day. You will need to use the drops until the infection has gone, and then for an extra 14 days after the infection has cleared up in order to prevent re-infection.
Symptoms such as itching and soreness should improve within a few days of using clotrimazole, although redness and skin scaling may take a little longer. If you feel there is no improvement in your symptoms after you have used the drops for about a week, make another appointment to see your doctor.
Otitis externa can be painful. You can take a simple painkiller such as paracetamol, or alternatively ibuprofen, to help relieve the pain.
To help stop further bouts of inflammation and infection, try not to let soap or shampoo get into your ear canal when you wash. You can do this when you have a shower by gently placing a piece of cotton wool coated in soft white paraffin (eg, Vaseline®) into your ear, but do not poke it in.
Otitis externa is more common in people who swim regularly compared to non-swimmers. If it is not possible for you to avoid swimming, try to protect your ears as much as possible.

It can occasionally cause some irritation when it is used at first, and a few people experience mild allergic-type reactions (such as redness and itching). If you experience these or any other symptoms, speak with your doctor or pharmacist for further advice.

Vanliga frågor
How long do I need to use clotrimazole ear drops for to ensure the infection is gone?
You should use the ear drops until the infection has cleared up, and then continue using them for an additional 14 days afterwards. This helps to prevent the infection from returning.
What should I do if my ear still hurts while using the clotrimazole drops?
Otitis externa, the ear inflammation clotrimazole treats, can be painful. You can take common painkillers like paracetamol or ibuprofen to help manage the pain while using the drops.
How can I prevent further ear infections caused by water getting into my ears?
To help prevent future inflammation and infection, try to avoid getting soap or shampoo in your ear canal when washing. A good way to do this during a shower is to gently place a piece of cotton wool coated in soft white paraffin (like Vaseline) into your ear, but be careful not to push it in too far.
