4.3 Contraindications
Should not be administered to patients hypersensitive to chloramphenicol, or any of the other ingredients of the preparation.
Patients with a known personal or family history of blood dyscrasias including aplastic anaemia.
4.4 Special warnings and precautions for use
The association or chloramphenicol with childhood leukaemia's and Gray baby syndrome warrants careful consideration before using ocular chloramphenicol in neonates and small children.
Chloramphenicol is absorbed systemically from the eye and toxicity has been reported following chronic exposure. Bone marrow hypoplasia, including aplastic anaemia and death, has been reported following topical use of Chloramphenicol. Whilst the hazard is a rare one, it should be borne in mind when assessing the benefits expected from the use of the compound. Where Chloramphenicol is used on a long- term or intermittent basis, it may be advisable to perform a routine blood profile before therapy and at appropriate intervals thereafter to detect any haemopoietic abnormalities.
In severe infections the topical use of chloramphenicol should be supplemented by appropriate systemic treatment.
Prolonged use of chloramphenicol eye drops should be avoided as it may increase the likelihood of sensitisation and emergence of resistant organisms. If any new infection appears during treatment, the antibiotic should be discontinued and appropriate measures taken. Chloramphenicol should be reserved for use only in infections for which it is specifically indicated.
Chloramphenicol does not provide adequate coverage against Pseudomonas aeruginosa and Serratia marcescens.
Do not use for more than 5 days without consulting a doctor.
Medical advice should be sought if there is no improvement in the condition after 2 days or if symptoms worsen at any time.
Patients should be referred to their doctor if any of the following apply:
• Disturbed vision
• Severe pain within the eye
• Photophobia
• Eye inflammation associated with a rash on the scalp or face
• The eye looks cloudy
• The pupil looks unusual
• Suspected foreign body in the eye
Patients should also be referred to their doctor if any of the following in his/her medical history apply:
• Previous conjunctivitis in the recent past
• Glaucoma
• Dry eye syndrome
• Eye surgery or laser treatment in the last 6 months
• Eye injury
• Current use of other eye drops or eye ointment
• Contact lens use
If you wear contact lenses, seek advice either from your contact lens practitioner (optician, optometrist) or doctor before you use this product. You should not wear your contact lenses during the course of treatment. If you wear soft contact lenses do not start wearing them for at least 24 hours after you have finished using the eye drops.
The packaging will convey the following information:
• If symptoms do not improve within 48 hours talk to your doctor
• Seek further immediate medical advice at any time if symptoms worsen
• Do not use if you are allergic to chloramphenicol or any of the ingredients
Phenylmercuric nitrate is irritating to the skin. Topical application to eyes has been associated with mercurialentis and atypical band keratopathy.
4.5 Interaction with other medicinal products and other forms of interaction
Chymotrypsin will be inhibited if given simultaneously with chloramphenicol.
4.6 Fertility, pregnancy and lactation
Safety for use in pregnancy and lactation has not been established. A serious side effect of chloramphenicol is Gray baby syndrome, known to occur if chloramphenicol is given to neonates.
Chloramphenicol has also been associated with childhood leukaemia’s and bone marrow depression. It is likely that systemic absorption of chloramphenicol occurs following ocular administration.
Chloramphenicol is known to penetrate well into foetal circulation and is found in breast milk at low concentrations. The reduced ability of the foetus and neonate to metabolise chloramphenicol may lead to the drug concentrating in the foetal or neonatal circulation.
Therefore topical ocular chloramphenicol must be used only if considered essential and not prophylactically or to treat minor infections.
4.7 Effects on ability to drive and use machines
The use of an eye ointment may cause some blurring of vision. Patients should not drive or operate hazardous machinery unless vision is clear.
4.8 Undesirable effects
Local effects:
Sensitivity reactions such as transient irritation, burning, stinging, itching and dermatitis.
Systemic effects:
Bone marrow depression, aplastic anaemia, angioneurotic oedema, anaphylaxis, urticaria, fever, vesicular and maculopapular dermatitis have been reported and are causes for discontinuation.
