What Ceftazidime is used for
Ceftazidime is an anti-infective medicine, specifically an antibiotic from the cephalosporin family. It is used in ophthalmology to treat severe bacterial infections of the eye. These conditions require prompt and expert medical attention to prevent serious complications and preserve vision.
- Bacterial Endophthalmitis: This is a serious infection inside the eye, often affecting the vitreous (the jelly-like substance filling the eye) and retina. Ceftazidime is particularly effective against gram-negative bacteria, including Pseudomonas, which can cause this type of infection. It is typically given as an intravitreal injection, meaning directly into the eye, by an ophthalmologist.
- Fortified Topical for Keratitis: Keratitis is an inflammation or infection of the cornea, the clear front part of the eye. In some severe cases of bacterial keratitis, Ceftazidime may be used as a ‘fortified topical’ preparation. This means a specially prepared, higher concentration eye drop, which is also prescribed and supervised by an eye specialist.
It is crucial to understand that these are serious eye conditions requiring immediate and specialised care. Ceftazidime is used as part of a comprehensive treatment plan under the strict guidance of an ophthalmologist.
How it works
Ceftazidime is a third-generation cephalosporin antibiotic. It works by targeting and killing specific types of bacteria that cause eye infections. Its mechanism involves interfering with the bacteria’s ability to build and maintain their cell walls, which are essential for their survival. Without a strong cell wall, the bacteria cannot survive and reproduce, leading to the resolution of the infection.
A key feature of Ceftazidime is its strong activity against a wide range of gram-negative bacteria, including a particularly difficult-to-treat bacterium called Pseudomonas aeruginosa. This makes it a valuable medicine for severe eye infections where such bacteria are suspected or confirmed to be the cause.
By effectively eliminating the harmful bacteria, Ceftazidime helps to reduce inflammation, prevent further damage to eye tissues, and aid in the recovery process from serious eye infections.
How it’s used
Ceftazidime is a medicine that is administered by eye specialists in a hospital or clinic setting and is never for self-use. The way it is used depends on the specific eye condition being treated:
- For Bacterial Endophthalmitis: Ceftazidime is typically given as an intravitreal injection. This means a very small, precise amount of the medicine (2.25 mg/0.1 mL) is injected directly into the vitreous gel inside the eye. This procedure is performed by a qualified ophthalmologist under sterile conditions to ensure the medicine reaches the site of infection effectively. It is usually a single dose, but your doctor may decide to repeat the injection after 48-72 hours if needed, based on your response to treatment and the severity of the infection.
- For Fortified Topical for Keratitis: In certain severe cases of keratitis, Ceftazidime may be prepared as a ‘fortified topical’ eye drop. This is a specially compounded, higher concentration eye drop that is applied to the surface of the eye. The frequency and duration of these drops will be strictly determined by your ophthalmologist.
It is very important to follow all instructions given by your ophthalmologist regarding your treatment. Do not attempt to administer this medicine yourself or change the dosage or frequency. This medicine is part of a specialised treatment plan for serious eye conditions and requires professional administration and monitoring.
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. This is given only by specialists in a hospital or clinic setting and is never for self-use.
Precautions & side effects
As with any powerful medicine, especially one administered for serious eye conditions, certain precautions are taken with Ceftazidime:
- Hospital Use Only: Ceftazidime is a prescription medicine intended for hospital use only. It is administered by qualified ophthalmologists and never for self-use.
- Intravitreal Administration: When given as an intravitreal injection, the procedure is performed under strict sterile conditions by an eye specialist to minimise risks.
- Combination Therapy: For bacterial endophthalmitis, Ceftazidime is often used in combination with another antibiotic, vancomycin. This ‘pairing’ provides broad-spectrum coverage against a wider range of bacteria (both gram-negative and gram-positive), which is crucial when the exact type of bacteria causing the infection is not yet known or when a mixed infection is suspected.
- Monitoring: Your ophthalmologist will closely monitor your eye’s response to the treatment. This includes regular examinations to check for improvement in the infection and to identify any potential side effects.
- Allergies: Always inform your doctor if you have any known allergies to antibiotics, especially to cephalosporins or penicillins, as there can be cross-reactivity.
- General Warnings: 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. Use only as directed by a qualified ophthalmologist.
Your doctor will discuss all potential risks and benefits with you before administering Ceftazidime and will ensure it is the most appropriate treatment for your specific condition.
Understanding Serious Eye Infections
Our eyes are precious and complex organs, and sometimes they can be affected by serious infections that require immediate and specialised medical attention. Two such conditions where Ceftazidime is often used are bacterial endophthalmitis and severe bacterial keratitis.
Bacterial Endophthalmitis is a very serious infection inside the eye. It can occur after eye surgery, an eye injury, or in rare cases, spread from another part of the body. Symptoms can include severe eye pain, redness, blurred vision, sensitivity to light, and sometimes pus or discharge from the eye. Because this infection can rapidly lead to vision loss if not treated promptly and effectively, it is considered a medical emergency. Treatment often involves injecting antibiotics directly into the eye to deliver the medicine precisely where it is needed.
Bacterial Keratitis is an infection of the cornea, the clear, dome-shaped front surface of your eye. It can be caused by bacteria, often after an eye injury, improper contact lens use, or a weakened immune system. Symptoms include eye pain, redness, blurred vision, tearing, and a feeling like something is in your eye. Severe forms of bacterial keratitis can also threaten vision and require intensive antibiotic treatment, sometimes with specially prepared ‘fortified’ eye drops.
It is vital to remember that if you experience any sudden changes in your vision, severe eye pain, redness, or discharge, you should seek immediate medical attention from an ophthalmologist. Early diagnosis and treatment are key to preserving your vision.
General Advice for Eye Medicine Use and Hygiene
While Ceftazidime is administered by specialists, understanding general eye care and hygiene is important for overall eye health and recovery from any eye condition. When using any eye medicine, whether prescribed drops or ointments, proper technique and hygiene are crucial to prevent further infection and ensure the medicine works effectively. Always wash your hands thoroughly with soap and water before touching your eyes or handling any eye medicine. Avoid touching the tip of the medicine bottle or tube to your eye or any other surface, as this can contaminate the medicine. If you are ever prescribed eye drops for home use (not Ceftazidime, which is hospital-administered), tilt your head back, pull down your lower eyelid to form a small pocket, and gently squeeze the prescribed number of drops into the pocket. Close your eye gently for a minute or two to allow the medicine to absorb. For ointments, apply a thin strip along the inside of your lower eyelid. Always replace the cap tightly after use.
Store all eye medicines as directed by your pharmacist or doctor, usually in a cool, dry place away from direct sunlight. Never share your eye medicines with anyone else, and do not use expired medicines. If you wear contact lenses, your doctor will advise you on when it is safe to wear them again during and after treatment for an eye infection.
When to Seek Further Help
Even after receiving treatment in a hospital setting, it is important to be aware of your symptoms and know when to seek further medical advice. Your ophthalmologist will schedule follow-up appointments to monitor your progress. It is crucial to attend all these appointments. If, between appointments, you experience any worsening of your symptoms, such as increased eye pain, redness, blurred vision, new discharge, or any other concerning changes, contact Pristine Eye Hospitals or your ophthalmologist immediately. Do not wait for your next scheduled appointment if you feel your condition is deteriorating. Your doctor needs to be aware of any changes to adjust your treatment plan if necessary. Always communicate openly with your healthcare team about any concerns or questions you may have regarding your eye health and treatment.
