Description
Chloramphenicol Overview
Chloramphenicol Eye Ointment is a topical antibiotic medicine used for the short-term treatment of acute bacterial conjunctivitis and other superficial bacterial eye infections. It works by stopping the growth of susceptible bacteria, allowing the infection to clear and symptoms such as redness, discharge, irritation, and soreness to improve.
In the UK, chloramphenicol eye ointment is classified as a pharmacy medicine, meaning it can be supplied following assessment by a pharmacist. It is intended for short courses only and should be used exactly as directed.
Understanding Bacterial Eye Infections
What is conjunctivitis?
Conjunctivitis is inflammation of the conjunctiva, the thin transparent membrane covering the white of the eye and lining the inside of the eyelids. It has several possible causes, including bacterial infection, viral infection, allergy, and irritation.
Chloramphenicol is effective only when the cause is bacterial.
Symptoms of bacterial conjunctivitis
Bacterial conjunctivitis commonly presents with:
- Redness of one or both eyes
- Yellow or green discharge
- Sticky eyelids, particularly on waking
- Gritty or burning sensation
- Mild swelling of the eyelids
Pain, sensitivity to light, or changes in vision are not typical and require urgent assessment.
What Is Chloramphenicol Eye Ointment?
Chloramphenicol Eye Ointment contains chloramphenicol, a broad-spectrum antibiotic that has been used in ophthalmology for many years.
As an ointment formulation, it:
- remains in contact with the eye surface for longer than drops
- is particularly useful for night-time use
- may cause temporary blurred vision after application
Chloramphenicol eye preparations are commonly used in UK primary care and community pharmacy for uncomplicated bacterial eye infections.
How Does Chloramphenicol Eye Ointment Work?
Mechanism of action
Chloramphenicol works by:
- inhibiting bacterial protein synthesis
- binding to bacterial ribosomes
- preventing bacteria from multiplying
This stops the infection from progressing and allows the immune system to clear the bacteria.
Spectrum of activity
Chloramphenicol is active against many bacteria commonly responsible for eye infections, including:
- Staphylococcus species
- Streptococcus species
- Haemophilus influenzae
It is not effective against viral, allergic, or fungal eye conditions.
What Chloramphenicol Treats — and What It Does Not
What it treats
Chloramphenicol Eye Ointment is used to treat:
- acute bacterial conjunctivitis
- superficial bacterial eye infections
- infected eyelids where bacteria are involved
What it does not treat
Chloramphenicol does not:
- treat viral conjunctivitis
- relieve allergic eye symptoms
- treat fungal eye infections
- replace medical care for serious eye conditions
If symptoms do not improve promptly, reassessment is essential.
Who Would Use Chloramphenicol Eye Ointment?
Chloramphenicol Eye Ointment may be suitable for:
- adults and children aged 2 years and over
- individuals with symptoms consistent with bacterial conjunctivitis
- those assessed by a pharmacist as suitable for pharmacy treatment
It is often chosen when discharge is present and the eyes are sticky or crusted.
Who Should Avoid Chloramphenicol Eye Ointment
Chloramphenicol Eye Ointment may not be suitable if:
- you are allergic to chloramphenicol
- you have a history of bone marrow disorders
- you wear contact lenses during treatment
- you have severe eye pain or sudden vision changes
Always tell your pharmacist about existing medical conditions.
How to Use Chloramphenicol Eye Ointment
Dosage and application
- Apply a small ribbon of ointment (approximately 1 cm) inside the lower eyelid
- Use 3 to 4 times daily, unless advised otherwise
- Treatment usually lasts 5 days
Wash hands before and after use and avoid touching the nozzle to the eye.
Important usage advice
- Do not wear contact lenses during treatment
- Complete the full course even if symptoms improve
- Temporary blurred vision may occur after application
Safety, Warnings and Side Effects
Common side effects
Some people may experience:
- mild stinging or burning
- temporary blurred vision
- mild eye irritation
These effects usually settle quickly.
Rare but serious considerations
Very rarely, chloramphenicol has been associated with blood disorders when used systemically. The risk from short-term topical eye use is extremely low, but this is why:
- treatment duration is limited
- repeated or unnecessary courses are avoided
When to Seek Medical Advice
Seek urgent medical advice if:
- symptoms worsen or do not improve after 48 hours
- you experience significant eye pain
- vision becomes blurred or reduced
- light sensitivity develops
- symptoms affect a child under 2 years
These may indicate a more serious eye condition.
Use in Pregnancy and Breastfeeding
If you are pregnant or breastfeeding, speak to a pharmacist or GP before using chloramphenicol eye ointment. It is generally avoided unless clearly advised.
How Chloramphenicol Compares to Other Eye Treatments
Ointment vs eye drops
- Ointment provides longer contact time and is useful at night
- Drops cause less blurring and are often preferred during the day
In some cases, both formulations may be used together.
Antibiotic vs non-antibiotic eye treatments
Lubricating eye drops can soothe irritation but will not treat bacterial infection.
Supporting Eye Health During Infection
To reduce spread and support recovery:
- clean away discharge with sterile cotton wool and cooled boiled water
- avoid touching or rubbing the eyes
- do not share towels or pillows
- wash hands frequently
Good hygiene helps prevent reinfection.
Chloramphenicol Summary
Chloramphenicol Eye Ointment is a trusted short-term antibiotic treatment for bacterial eye infections. When used correctly and for the recommended duration, it is effective, well tolerated, and widely used in UK pharmacy and primary care settings.
If symptoms persist, worsen, or are accompanied by pain or vision changes, further medical assessment is essential.
