About soybean oil eye drops
Type of medicine | Eye lubricant |
Used for | Dry eyes (in adults and children) |
Also called | Emustil® |
Available as | Single-use units of eye drops |
Emustil® is a lubricating eye drop, also known as an 'artificial tear'. Emustil® eye drops contain two ingredients - soybean oil and natural phospholipids. Soybean oil relieves eye dryness and soreness. The natural phospholipids are substances which are naturally found in your tears, but which can be reduced in people with dry eyes. The eye drops moisten, soothe and lubricate the surface of your eye, making it feel more comfortable.
Emustil® eye drops are available on prescription, or you can buy them without a prescription through a pharmacy.
How to use soybean oil eye drops
Wash your hands well before you use the drops.
Twist off the tip of a single-dose unit.
Tilt your head back a little and pull the lower lid of your eye downwards to form a pocket.
Hold the unit upside down near to your eye. Try not to touch your eye as you do this.
Apply enough pressure to release one drop into your eye. Only use a second drop if the first drop missed going into your eye.
Close your eye for a minute or two, and press gently on the side of your nose where the corner of your eye meets your nose. This helps to stop the drop from draining away and keeps it in your eye.
Repeat the process in your other eye if required.

Getting the most from your treatment
Before you start using the eye drops, read the manufacturer's printed information leaflet supplied with the pack. It will give you more information about using the drops and will provide a list of any side-effects which you could experience.
Use one drop into the eye (or eyes) affected by dryness. You can use the drops up to four times a day. If the drops have been prescribed for you then you should follow the directions given to you by your doctor.
If you forget to use the drops at your 'usual' time, do not worry; just put them in when you remember. Do not 'double up' the number of drops you use to make up for forgetting to use them.
When first put in, the eye drops can cause blurred vision. This should quickly clear. Make sure you can see clearly again before you drive and before you use tools or machines.
If you are using any other eye drops or ointments, leave about ten minutes between applying each one. It is usually recommended that you use lubricating drops like Emustil® last. This is so that the drops stay in contact with your eye and lubricate it for as long as possible.
If your symptoms do not improve within a few days, see your doctor for further advice.
