You will have been prescribed fusidic acid eye drops to treat an eye infection called conjunctivitis. The drops kill the bacteria which are the cause of the infection.

Conjunctivitis causes your eye to become inflamed, feel gritty, and water more than usual. The white of your eye may look red, and your eyelids may become swollen and stuck together with a discharge when you wake up in the morning. Only one eye may be infected to begin with, but it can often spread to both eyes. Most cases of infective conjunctivitis clear within a week or so without treatment, but more severe infections (or infections which do not clear on their own) require an antibiotic eye drop such as fusidic acid.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start using fusidic acid eye drops it is important that your doctor or pharmacist knows:

  • If you are pregnant or breast-feeding.
  • If you have ever had an allergic reaction to a medicine, or to any other eye drops.
  • If you are taking or using any other medicines, including those available to buy without a prescription, herbal and complementary medicines.

Before you start this treatment, read the manufacturer's printed information leaflet from the pack. The leaflet will give you more information about the drops, and a full list of side-effects which you may experience from using them. If your eyes have an obvious discharge or 'crust', it can help if you bathe them with cool clean water before using the drops.

  1. Wash your hands well.
  2. Remove the cap.
  3. Tilt your head back a little and gently pull the lower lid of your eye out to form a pocket.
  4. Hold the tube upside down near to your eye. Try not to touch your eye as you do this.
  5. Gently squeeze the tube to release one drop into the bottom eyelid.
  6. 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.
  7. Repeat the process in your other eye if you have been asked to use the drops in both eyes.
  8. Replace the cap.
  • Fusidic acid eye drops are supplied as a gel in a tube. As the drop of gel enters your eye, it will become a liquid.
  • Use the drops twice a day unless you have been told otherwise by your doctor. Try not to miss any doses. If you forget to put the drops in on time, do it as soon as you remember.
  • When you first put a drop into your eye, it may cause blurred vision. This should quickly clear, but make sure you can see clearly before you drive or use machines or tools.
  • Your eye should start to feel better within a few days. Continue to use the drops for a further two days after your symptoms have gone. This will help to prevent the infection from coming back.
  • Take care to avoid spreading the infection from one eye to the other, and to other members of your family. Washing your hands regularly (particularly after touching your eyes), and not sharing towels or pillows will help to prevent the infection from spreading.
  • Eye infections can cause your eyes to become more sensitive to sunlight than usual. Wearing sunglasses may help to prevent this.
  • Do not wear contact lenses until your symptoms have completely gone. Wait for 24 hours after the last dose of eye drops before using your lenses again.
  • If you are using any other eye drops or eye ointments, leave at least five minutes between applying each preparation.
  • If you feel your infection is no better after a week, make another appointment to see your doctor for advice. If you feel your symptoms are becoming worse despite using the drops, you should arrange to see your doctor for advice straightaway. In particular, see your doctor again if your eye becomes painful, if light starts to hurt your eyes, or if your sight is affected.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with fusidic acid eye drops. You will find a full list in the manufacturer's information leaflet supplied with your drops. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Common side-effects of
fusidic acid eye drops
What can I do if I experience this?

If you experience any other symptoms which you think may be due to these eye drops, ask your doctor or pharmacist for advice.

  • Keep all medicines out of the reach and sight of children.
  • Store in a cool, dry place, away from direct heat and light.
  • Throw away the tube after you have finished your course of treatment, even if there is some left. Do not keep to use later, as eye drops must not be used if the container has been opened for longer than four weeks.

Never use more than the prescribed dose. If you suspect that someone has swallowed some of this medicine, go to the accident and emergency department of your local hospital at once. Take the container with you, even if it is empty.

If you buy any medicines check with a pharmacist that they are safe to use with your other medicines.

If you are having an operation or dental treatment, tell the person carrying out the treatment which medicines you are using.

This medicine is for you. Never give it to other people even if their condition appears to be the same as yours.

Never keep out-of-date or unwanted medicines. Take them to your local pharmacy which will dispose of them for you.

If you have any questions about this medicine ask your pharmacist.
