I-Guard Eye Drop 0.5% — Chloramphenicol Antibiotic by Beximco

I-Guard Eye Drop 0.5% — Chloramphenicol | Beximco Pharmaceuticals

Overview

I-Guard Eye Drop 0.5% is a standard-strength Chloramphenicol ophthalmic solution for bacterial conjunctivitis and superficial eye infections. Chloramphenicol 0.5% is one of the most widely used first-line topical antibiotics for eye infections globally due to its broad spectrum of coverage and well-established safety profile for short-term use. For diabetic patients, maintaining ocular health is critical — prompt treatment of infections prevents complications on already compromised diabetic eyes.

Mechanism of Action

Chloramphenicol inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit and blocking the peptidyl transferase reaction. Bacteriostatic activity against most organisms. Covers: Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, Moraxella lacunata, Neisseria gonorrhoeae, and many other bacterial conjunctivitis pathogens.

Indications

• Acute and chronic bacterial conjunctivitis
• Blepharoconjunctivitis
• Trachoma (adjunct to systemic therapy)
• Bacterial keratitis — superficial
• Post-operative prophylaxis

Dosage

Critical Diabetic Patient Warnings

• Impaired corneal healing: Diabetic corneas heal more slowly — if bacterial infection progresses to keratitis, early ophthalmologist review is essential
• Do not self-treat repeatedly: Recurrent eye infections in diabetics may signal worsening immune function or glucose control — review HbA1c
• Distinguish infectious vs. diabetic eye disease: Redness and discharge may be due to infectious conjunctivitis OR diabetic vascular complications — confirm diagnosis
• Avoid prolonged courses: Use for minimum effective duration; prolonged use without review is not safe

Side Effects

Contraindications

• Known hypersensitivity to chloramphenicol
• Herpes simplex keratitis (viral — antibiotic ineffective)
• Fungal ocular infections
• Neonates — risk of systemic absorption and grey baby syndrome
• History of blood dyscrasia or aplastic anaemia
