About ciprofloxacin eye preparations

Ciprofloxacin eye drops and ointment are used to treat bacterial eye infections. They work by helping to kill the germs (bacteria) which are causing the infection. Eye infections are a common cause of conjunctivitis. In conjunctivitis, your eye becomes inflamed, feels gritty, and may 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 often spreads to both eyes. Most cases of infective conjunctivitis clear within a week or so without treatment. For more severe infections, or for infections which do not clear on their own, an antibiotic eye drop such as ciprofloxacin is used.
Ciprofloxacin is also prescribed to treat corneal ulcers. A corneal ulcer is one which forms on the delicate layer covering the surface of your eye.
Before using ciprofloxacin eye preparations
Tillbaka till innehållSome 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 ciprofloxacin it is important that your doctor or pharmacist knows:
Om du är gravid eller ammar.
If you have ever had an allergic reaction to ciprofloxacin or any other antibiotic, or to any other eye drops.
Om du tar eller använder några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

How to use ciprofloxacin eye preparations
Tillbaka till innehållBefore you start this treatment, read the manufacturer's printed information leaflet from the pack. The leaflet will give you more information about the drops or ointment, and a full list of possible side-effects. If your eyes have an obvious discharge or 'crust', it can help if you bathe them with cool clean water before using ciprofloxacin.
How to use eye drops
First wash your hands thoroughly.
For most eye drops, you should not shake the bottle. Some suspension eye drops may need to be shaken before use. Check the label on your medicine first. Remove the cap, trying not to touch the tip of the bottle..
It helps to do the following steps in front of a mirror:
Luta huvudet lite bakåt och dra det nedre ögonlocket nedåt för att bilda en ficka.
Hold the bottle upside down near to your eye. Try not to touch your eye with the bottle as you do this, but don't worry if you do.
Gently press the base of the bottle to release one drop into your eye. Your eye can only hold about one drop of liquid, any more will over-flow down your cheek.
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 liquid from draining away and keeps it in your eye.
Repeat the process in your other eye if you have been told to use the drops in both eyes.
If you need to administer more than one drop into an eye, wait a few minutes before repeating the process. If you need to use more than one eye drop medicine at a time, wait at least 5 minutes between each medicine.
Replace the cap after use and store out of reach of children.
If you have any difficulty using eye drops ask a pharmacist for advice. There are other techniques that may suit you better and devices available to help you.
How to use eye ointment
First wash your hands.
Remove the cap from the tube.
Pull the lower lid of your eye downwards to form a pocket.
Hold the tube upside down near to your eye.
Gently press on the tube to release a thin line of ointment along the inside of your lower eyelid. Try not to touch your eye with the end of the tube as you do this.
Blink a few times to spread the ointment around the inside of your eye.
Repeat the process in your other eye if you have been told to use it in both eyes.
Replace the cap on the tube.

Tillbaka till innehållIf you have a corneal ulcer, you will need to use ciprofloxacin eye drops regularly, day and night, for the first two days. Your doctor will tell you how often to use them - this is often every 15 minutes to begin with, then every 30 minutes, then every hour. On day three, it is likely that you will be able to reduce the frequency to every four hours. Try not to miss putting the drops in but, if you do forget, put them in as soon as you remember.
For other infections, use the drops regularly exactly as your doctor tells you to. If the infection is severe, this is likely to be every two hours for the first two days. (Just use the drops while you are awake - you do not need to wake yourself up during the night to put them in.) On day three, reduce the frequency down to four times a day.
Ciprofloxacin eye ointment is frequently prescribed to use at night. If you are using eye drops during the day, you are unlikely to need to use the ointment during the day as well. Sometimes only the eye ointment is prescribed, in which case you may be asked to use it 3-4 times during the day, as well as at bedtime.
If your symptoms do not improve within a few days, or if they become worse, speak again with your doctor.
When you first put the drops or ointment into your eye, it may cause blurred vision. This should quickly clear, but make sure you can see clearly again before you drive and before using machines or tools.
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.
If the tip of the tube/bottle touches your eye(s) when putting the drops in, it is a good idea to squeeze out two or three drops straightaway on to some tissue and rinse the tip with salt water.
Eye infections can cause your eyes to become more sensitive to sunlight than usual. Wearing sunglasses may help to prevent this.
If you are using any other eye drops or eye ointments, leave 5-10 minutes between applying each preparation.
Even when your eye appears normal again, there may still be some germs (bacteria) present. It is important to continue to use ciprofloxacin for a further 48 hours once your eye appears normal. This will help to make sure that all the bacteria have been killed. It is likely that you may need to use ciprofloxacin for about a week. You should not use it for longer than three weeks.
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.

Can ciprofloxacin eye preparations cause problems?
Tillbaka till innehållFörutom sina nyttiga effekter kan de flesta läkemedel orsaka oönskade biverkningar, även om inte alla upplever dem. Dessa förbättras vanligtvis när din kropp anpassar sig till det nya läkemedlet, men tala med din läkare eller apotekare om någon av följande biverkningar fortsätter eller blir besvärliga.

Whilst using ciprofloxacin eye drops or ointment, if you feel any pain or swelling of the tendons (the tough fibres that attach your muscles to bone - for example, the Achilles heel), stop treatment and let your doctor know straightaway. Tendonitis is a rare side-effect of using ciprofloxacin.
