About gentamicin ear drops
|Type of medicine||Anti-infective ear drop|
|Used for||Treatment of ear infections in adults and children|
Gentamicin ear drops are prescribed for bacterial ear infections. The drops kill germs (bacteria) which are the cause of infection. If the ear is swollen as well as infected (as in otitis externa, for example), your doctor may prescribe gentamicin ear drops which also contain hydrocortisone. These drops will reduce the inflammation as well as treat the infection.
Before using gentamicin ear drops
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you (or your child) start using gentamicin drops, it is important that your doctor knows:
- If you have a burst (perforated) eardrum.
- If you are pregnant or breast-feeding.
- If you have ever had an allergic reaction to gentamicin or to any other antibiotic, or to any other ear drops.
- If you have a condition called myasthenia gravis. This is a condition which causes muscle weakness.
- If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
How to use gentamicin ear drops
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about the drops and will provide you with a full list of any side-effects which you may experience from using them.
- Wash your hands before you begin.
- Clean your ear gently with warm water and pat it dry.
- Remove the cap from the bottle of ear drops.
- Lie down, or tilt your head a little, so that the affected ear is facing upwards.
- Gently pull your earlobe to straighten the ear canal.
- Hold the container upside down near to the ear. Try not to touch the inside of your ear as you do this.
- Apply enough pressure to the container to release two or three drops 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 you have been asked to use the drops in both ears.
- Replace the cap on to the bottle of drops.
Getting the most from your treatment
- Use the drops exactly as you have been advised by your doctor. It is likely that your doctor will recommend you use the drops three or four times during the day, and also at night. Try not to miss any doses. If you forget to put the drops in on time, do it as soon as you remember.
- Do not try to clean inside your ear with cotton buds. If you stick buds or other objects into your ear, they can damage and irritate the inflamed skin, and make things worse. Just wipe the outside of your ear with a clean cloth or tissue if any discharge appears.
- You will be prescribed a short course of treatment (usually no more than 7-10 days). If you feel your infection is no better after this time, make another appointment to see your doctor for advice.
