What are Ciloxan eye drops used for?
- Bacterial infections of the eye, eg conjunctivitis.

How do Ciloxan eye drops work?
Ciloxan eye drops contain the active ingredient ciprofloxacin, which is a type of medicine called a quinolone antibiotic. Antibiotics are used to treat infections caused by bacteria.
Ciprofloxacin is effective against various types of bacteria, some of which tend to be resistant to other commonly used antibiotics.
Ciprofloxacin kills bacteria by stopping a bacterial enzyme called DNA-gyrase from working. This enzyme is involved in replicating and repairing the genetic material (DNA) of the bacteria. If it doesn't work, the bacteria can't repair themselves or reproduce. This kills the bacteria and clears up the infection.

Ciprofloxacin eye drops are administered into the eye to treat various types of bacterial eye infections. Administering them directly into the eye allows the ciprofloxacin to act locally on the bacteria that are causing the infection.
How do I use Ciloxan eye drops?
- Infections of the eyes or eyelids: The drops only need to be applied during the day. One or two drops should be put in the affected eye(s) four times a day. In severe infections, your doctor may ask you to use one or two drops every two hours during waking hours for the first two days and then reduce application to four times a day for the rest of the course. Always follow your doctor's instructions.
- Corneal ulcers: The drops should be applied throughout the day and night as follows: On the first day, put two drops into the affected eye(s) every 15 minutes for the first six hours and then two drops into the affected eye(s) every 30 minutes for the remainder of the day. On the second day, put two drops in the affected eye every hour. On the third to the fourteenth day, put two drops in the affected eye(s) every four hours.
How to use your eye drops
- If you forget a dose of Ciloxan drops, apply the missed dose as soon as you remember, unless it's almost time for your next dose. In this case, leave out the missed dose and continue with the prescribed routine as usual. Don't use double the amount of eye drops to make up for a missed dose.
- Make sure you complete the course of treatment that your doctor has prescribed, even if your eye appears to be better. Stopping treatment early increases the chance that your symptoms will come back and that any bacteria will grow resistant to the antibiotic.
- Get medical advice immediately if your symptoms get worse at any point during treatment, or if you think you have developed a new infection.
- Do not use Ciloxan for longer than prescribed by your doctor. The drops should not normally be used for longer than 21 days.
What should I know before using Ciloxan eye drops?
- Don't wear contact lenses while you are using Ciloxan eye drops. This is because the drops contain a preservative that can be absorbed by contact lenses and cause eye irritation. Also when you have an eye infection wearing contacts can make it worse.
- Your vision may blur temporarily after you have put the drops into your eye. Don't drive or operate machinery until this has worn off.
- If you get a skin rash or any other sign of allergic reaction, for example swelling of the face or throat, tingling, itching, shortness of breath or collapse, you should stop using the eye drops and consult your doctor immediately.
- Ciloxan eye drops are sterile until opened and keep for four weeks after you first open them. You should dispose of any drops that are left after you've finished your course of treatment. Don't keep any leftover drops 'just in case'. If kept for more than four weeks after opening they could become contaminated with germs that could cause further eye infections.
Who shouldn't use Ciloxan eye drops?
Can I use Ciloxan eye drops while pregnant or breastfeeding?
- The safety of these eye drops for use during pregnancy has not been established. As with all medicines they should not be used during pregnancy unless considered essential by your doctor, and only if the potential benefits outweigh any possible risk to the developing baby. Ask your doctor for more information.
- It's not known if ciprofloxacin passes into breast milk after being used in the eye. When taken by mouth ciprofloxacin does pass into breast milk. Ciloxan eye drops should therefore be used with caution during breastfeeding and only if the potential benefits outweigh any possible risk to the nursing infant. Seek further medical advice from your doctor.
- If your doctor does prescribe you Ciloxan eye drops while you are pregnant or breastfeeding you can minimise the amount of medicine that is absorbed into your bloodstream by pressing on your tear duct (the corner of the eye closest to the nose) while putting in the drops, and for a few minutes after.

However, you should always tell your doctor or pharmacist if you're using any other medicines, including those bought without a prescription and herbal medicines, before you start treatment, so they can check that the combination is safe.
