Tell your doctor before using these drops if you are allergic to aspirin or to medicines called non-steroidal anti-inflammatory drugs (NSAIDs).

Use one drop twice daily for two weeks, unless you have been told otherwise.

When you first put the drops in, they may cause a little irritation or blurred vision. This soon passes.

Available asEye drops

Bromfenac belongs to a group of medicines known as non-steroidal anti-inflammatory drugs (NSAIDs). The eye drops are used short-term to relieve eye pain and swelling after cataract surgery.

To make sure this is the right treatment for you, before you start using the eye drops it is important that your doctor knows:

  • If you have ever had an allergic reaction to a medicine. It is particularly important that you tell your doctor if you know you are allergic to an NSAID such as naproxen, diclofenac, or ibuprofen, or if you have ever had a bad reaction to aspirin.
  • If you have a tendency to bleed easily.
  • If you know you have an eye infection.
  • If you have sugar diabetes or rheumatoid arthritis.
  • If you are pregnant or breast-feeding.
  • If you are taking any other medicines or using any other eye drops. This includes any medicines or creams 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 the eye drops and will also provide you with a full list of the side-effects which you could experience from using them.

How to use eye drops

  1. First wash your hands.
  2. Remove the cap.
  3. Tilt your head back a little and pull the lower lid of your eye downwards to form a pocket.
  4. Hold the bottle upside down near to your eye. Try not to touch your eye as you do this.
  5. Gently apply enough pressure to the bottle to release one drop into your eye.
  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 told to use the drops in both eyes.
  8. Replace the cap.
  • Use the drops exactly as your doctor tells you to. It is usual to use one drop twice daily (morning and evening), starting the day after your cataract surgery and continuing for two weeks.
  • Take care not to touch your eye, fingers, or any other surface with the dropper of the bottle. This could contaminate the drops left in the bottle.
  • If your doctor has recommended you use another eye preparation as well as these drops then leave at least five minutes between putting in bromfenac drops and the other preparation.
  • Remember to use the drops at regular intervals and try not to miss any doses. If you do forget, use them as soon as you remember (unless it is nearly time for your next dose, in which case just use the drops when they are next due). Do not 'double up' to make up for forgetting to use the drops.
  • When first put in, eye drops can make your eyes water and may sometimes cause blurred vision. If this happens, it should quickly clear. Make sure you can see clearly again before you drive, or use tools or machines.
  • Try to keep the appointments which have been booked for you with the eye clinic. This is so your doctor can check on your progress.
  • Bromfenac can cause your eyes to become more sensitive to sunlight than usual. Avoid strong sunlight and do not use sunbeds while you are using the drops. If this happens, you may find wearing sunglasses helps.
  • If you normally wear contact lenses, your doctor will recommend you use glasses for a time following cataract surgery. This is to allow your eyes to recover from the procedure. Another reason why you should not wear contact lenses while you are using bromfenac eye drops is that they contain a preservative which can affect soft contact lenses.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the ones associated with bromfenac. You will find a full list in the manufacturer's information leaflet supplied with the eye 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.

Bromfenac side-effects (these affect less than 1 in 100 people)
What can I do if I experience this?
Eye discomfort or discharge, dry eyes, redness, itching, or irritation, eyelid puffinessThis can happen soon after applying the drops. It should pass quickly
Cough, nosebleeds, runny noseIf any of these become troublesome, mention it to your doctor

Bottles of eye drops contain preservatives which some people can develop an allergic reaction to. If your eye becomes red or inflamed after using the drops, contact your doctor for advice.

If you experience any other symptoms which you think may be due to the eye drops, speak with a doctor or pharmacist.

  • Keep all medicines out of the reach and sight of children.
  • Store in a cool, dry place, away from direct heat and light.
  • Bottles of eye drops only keep for four weeks once the bottle has been opened. Dispose of the bottle once your course of treatment has finished, even if there is still some solution remaining.

This preparation is for use in the eyes only. If someone swallows some of it, go to the accident and emergency department of your local hospital. Take the container with you, even if it is empty.

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

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

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

Do not 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.
