What Ciprofloxacin is used for

Ciprofloxacin is an anti-infective medicine, specifically an antibiotic, used to treat certain bacterial eye conditions. It is available as eye drops and eye ointment.

Bacterial Corneal Ulcer: This is a serious infection on the clear front surface of your eye (the cornea). Ciprofloxacin is particularly effective against a type of bacteria called Pseudomonas, which is a common cause of corneal ulcers, especially in people who wear contact lenses.
Conjunctivitis: This is an inflammation of the conjunctiva, the clear membrane that covers the white part of your eye and lines the inside of your eyelids. Ciprofloxacin can be used to treat bacterial forms of conjunctivitis.

Your ophthalmologist will determine if Ciprofloxacin is the right treatment for your specific eye infection.

How it works

Ciprofloxacin belongs to a group of antibiotics called fluoroquinolones. It is a ‘second-generation’ fluoroquinolone, meaning it is a modern and effective antibiotic. It works by killing the bacteria that cause eye infections. It is especially strong against certain types of bacteria, such as Pseudomonas, which can cause severe eye infections like corneal ulcers.

By stopping the growth and spread of these harmful bacteria, Ciprofloxacin helps to clear the infection and allows your eye to heal.

How it’s used

Ciprofloxacin eye drops or ointment should only be used exactly as prescribed by your ophthalmologist. The dosing can vary significantly depending on the severity of your eye condition.

For severe conditions like bacterial corneal ulcers, you might be advised to use the eye drops very frequently, sometimes as often as hourly. As your eye infection starts to heal, your doctor will gradually reduce (taper) the frequency of the drops. It is crucial to follow this tapering schedule precisely and not stop the medicine suddenly, even if your eye feels better, unless advised by your doctor.

If you are using eye drops:

Wash your hands thoroughly with soap and water before touching your eyes or the medicine bottle.
Tilt your head back slightly and pull down your lower eyelid to create a small pocket.
Hold the dropper tip directly over your eye, being careful not to touch your eye or any other surface with the tip.
Gently squeeze the bottle to release one drop into the pocket.
Close your eye gently for a minute or two. Do not blink excessively or rub your eye.
If you need to use more than one drop in the same eye, wait at least 5-10 minutes between drops to allow each drop to be absorbed.

If you are using eye ointment:

Wash your hands thoroughly.
Tilt your head back and pull down your lower eyelid to create a small pocket.
Hold the tube above your eye and gently squeeze a small ribbon of ointment (about 1 cm) into the pocket.
Close your eye gently and roll your eyeball around to spread the ointment.
You might experience blurred vision for a short time after applying ointment.

Always replace the cap immediately after use. Do not share your eye medicine with anyone else.

Always follow your ophthalmologist’s exact instructions.

Good to know

Prescription eye medicine — use only as directed by a qualified ophthalmologist. This page is for general education and is not a substitute for professional medical advice, diagnosis or a prescription. Do not self-medicate or reuse an old prescription.

Precautions & side effects

While Ciprofloxacin is generally safe and effective when used as directed, there are a few important points to keep in mind:

White Crystal Deposits: If you are using Ciprofloxacin intensively, especially for a corneal ulcer, you might notice harmless white crystal deposits forming on the surface of the ulcer. These are usually temporary and do not typically cause harm, but it’s important to mention them to your ophthalmologist during your follow-up visits.
Doctor’s Review is Essential: Ciprofloxacin is a powerful medicine for serious eye infections like corneal ulcers. It is not a substitute for regular check-ups and reviews by your ophthalmologist. Your doctor needs to monitor the healing process and adjust your treatment as necessary.
Prescription Medicine: Ciprofloxacin is a prescription-only eye medicine. This means you should only use it as directed by a qualified ophthalmologist. Do not self-medicate or reuse an old prescription, as this can be dangerous and lead to complications or antibiotic resistance.
Allergies: Inform your doctor if you have ever had an allergic reaction to Ciprofloxacin or any other fluoroquinolone antibiotics.
Contact Lenses: If you wear contact lenses and have an eye infection, you will likely be advised to stop wearing them until the infection has completely cleared and your doctor gives you permission to resume.

Always discuss any concerns or unusual symptoms with your ophthalmologist.

Understanding Eye Infections and Your Treatment

Eye infections can range from mild irritations to serious conditions that can affect your vision. When bacteria cause an infection, it’s called a bacterial eye infection. Two common types are conjunctivitis and corneal ulcers.

Conjunctivitis, often called ‘pink eye’, is an inflammation of the conjunctiva, the clear membrane that covers the white part of your eye and the inside of your eyelids. It can make your eye red, itchy, watery, and sometimes produce a discharge. Bacterial conjunctivitis needs antibiotic treatment to clear the infection and prevent it from spreading.

A corneal ulcer is a more serious condition. It’s an open sore on the cornea, the clear, dome-shaped front surface of your eye. Corneal ulcers can be very painful, cause blurred vision, sensitivity to light, and a feeling of something in your eye. If not treated promptly and correctly, a corneal ulcer can lead to permanent vision loss. People who wear contact lenses are at a higher risk for corneal ulcers, especially if they don’t follow proper hygiene practices. Ciprofloxacin is particularly effective against certain bacteria, like Pseudomonas, which are often involved in severe corneal ulcers.

Your ophthalmologist will carefully examine your eye to determine the type and severity of your infection before prescribing the most appropriate treatment, such as Ciprofloxacin.

Correct Use of Eye Drops and Ointments

Using your eye medicine correctly is vital for its effectiveness and to ensure a speedy recovery. Incorrect application can reduce the medicine’s benefit or even introduce more germs into your eye.

Hand Hygiene is Key: Always wash your hands thoroughly with soap and water before and after applying eye drops or ointment. This is the most important step to prevent further contamination.
Avoid Contamination: Never let the tip of the dropper or ointment tube touch your eye, eyelid, eyelashes, or any other surface. This can contaminate the medicine and introduce new bacteria into your eye.
Proper Application: Tilt your head back, gently pull down your lower eyelid to form a pocket. Look up and carefully squeeze the prescribed number of drops or a small ribbon of ointment into this pocket.
Gentle Closure: After applying, close your eye gently for a minute or two. Avoid blinking excessively or squeezing your eyes shut tightly, as this can push the medicine out.
Multiple Medicines: If you are using more than one type of eye drop, or both drops and ointment, wait at least 5-10 minutes between different medicines. Apply drops before ointments.
Follow Schedule: Stick to the dosing schedule provided by your doctor. Do not skip doses or stop the medicine early, even if your eye feels better, unless specifically told to do so. Stopping early can lead to the infection returning or becoming harder to treat.

General Hygiene, Storage, and When to Seek Help

Maintaining good eye hygiene is crucial, especially when you have an infection. Avoid rubbing your eyes, as this can worsen the irritation and spread the infection. If you wear contact lenses, your doctor will almost certainly advise you to stop wearing them until your eye has fully healed. Do not share towels, pillowcases, or eye makeup with others, as this can spread eye infections.

Store your Ciprofloxacin eye drops or ointment at room temperature, away from direct sunlight and excessive heat, unless your doctor or the packaging instructs otherwise. Always keep all medicines out of the reach of children.

It’s important to know when to seek further medical attention. While Ciprofloxacin is effective, if your symptoms worsen, you experience new symptoms, or if your eye does not seem to be improving after a few days of treatment, contact your ophthalmologist immediately. Signs to watch out for include increased pain, worsening redness, increased discharge, sudden changes in vision, or severe sensitivity to light.
