Generic Chloramphenicol Information

Introduction

Chloramphenicol is an antibiotic that interferes with bacterial protein synthesis. It is primarily used for serious infections caused by susceptible Gram‑positive and Gram‑negative bacteria when safer alternatives are unavailable or ineffective. In Hong Kong, Chloramphenicol is listed on the Hospital Authority formulary for selected indications such as meningitis, typhoid fever, and certain ocular infections. The active compound is Chloramphenicol, and it belongs to the broader medication group of antibiotics. In addition to its systemic use, topical formulations are employed for bacterial conjunctivitis and keratitis.

What is Chloramphenicol?

Chloramphenicol is a broad‑spectrum bacteriostatic antibiotic first isolated in 1947 from Streptomyces venezuelae. It is a synthetic derivative of the natural product chloramphenicol, licensed originally under the brand name Chloromycetin.

Chloramphenicol is the generic version of Chloromycetin, containing the same active compound Chloramphenicol. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

The drug is available in oral tablets, injectable powder for reconstitution, and ophthalmic eye‑drop formulations. Manufacturers vary by region; in Hong Kong the product is supplied by licensed overseas pharmaceutical companies that meet the standards of the Hong Kong Pharmacy and Poisons Ordinance.

How Chloramphenicol Works

Chloramphenicol binds reversibly to the 50S subunit of bacterial ribosomes. This interaction blocks the peptidyl transferase activity, preventing the formation of peptide bonds during translation. By halting protein synthesis, bacterial growth is arrested (bacteriostatic effect). The drug penetrates most body fluids, including cerebrospinal fluid, which explains its utility in central nervous system infections. After oral administration, peak plasma concentrations are reached within 1–2 hours; the drug is metabolized in the liver mainly by glucuronidation and eliminated via the kidneys. Its relatively long half‑life (1.5–3 hours in adults) allows for twice‑daily dosing in most systemic formulations.

Conditions Treated with Chloramphenicol

• Typhoid fever (Salmonella Typhi) – especially when resistance to fluoroquinolones or third‑generation cephalosporins is documented.
• Meningitis caused by Haemophilus influenzae or Neisseria meningitidis in patients who cannot tolerate β‑lactams.
• Bacterial conjunctivitis and keratitis – topical eye drops treat Gram‑negative organisms such as Pseudomonas aeruginosa.
• Rickettsial infections – including scrub typhus, where Chloramphenicol is an alternative to doxycycline.
• Severe or life‑threatening infections with multi‑drug‑resistant organisms when other agents are contraindicated.

In Hong Kong, outbreaks of Salmonella foodborne illness and occasional cases of bacterial meningitis make Chloramphenicol a valuable rescue therapy, especially in tertiary hospitals.

Patient Groups Most Likely to Benefit

• Adults with confirmed or highly suspected infections by Chloramphenicol‑susceptible bacteria where first‑line agents are ineffective, contraindicated, or unavailable.
• Patients requiring central nervous system penetration, such as meningitis, because the drug reaches therapeutic levels in cerebrospinal fluid.
• Individuals with penicillin or cephalosporin allergy needing an alternate antimicrobial class.
• Travelers returning from endemic regions with typhoid fever or rickettsial diseases, provided susceptibility testing supports use.

Contraindications include a known hypersensitivity to Chloramphenicol, pre‑existing bone‑marrow suppression, or concomitant use of drugs that markedly increase the risk of aplastic anemia. Elderly patients and those with hepatic impairment may require dose adjustments and closer monitoring.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset – nausea, vomiting, abdominal pain.
• Mild reversible thrombocytopenia – reduced platelet count that usually resolves after discontinuation.
• Transient neutropenia – mild decrease in neutrophil count, often without clinical infection.

Rare

• Gray baby syndrome – a potentially fatal condition in newborns caused by accumulation of the drug; not applicable to adult patients but important for prescribing in obstetric contexts.
• Hypersensitivity reactions – rash, pruritus, or mild fever.

Serious

• Aplastic anemia – irreversible bone‑marrow failure that may occur weeks to months after therapy; incidence is low but carries high mortality.
• Severe leukopenia – profound reduction of white blood cells leading to opportunistic infections.
• Hepatotoxicity – elevated transaminases, rare cases of clinically significant liver injury.

Drug–Drug Interactions

• Warfarin – Chloramphenicol may potentiate anticoagulant effects, increasing INR; monitor coagulation parameters closely.
• Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin) – may reduce Chloramphenicol plasma levels, decreasing efficacy.
• Cyclosporine – concurrent use can raise cyclosporine concentrations, raising nephrotoxicity risk.
• Alcohol – while not a direct pharmacologic interaction, heavy alcohol use can exacerbate hepatic metabolism disturbances.

Patients should disclose all current medications, herbal supplements, and over‑the‑counter products to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Oral tablets (250 mg) – typical adult dose for systemic infection: 500 mg every 6 hours (2 g/day) for 7–14 days, adjusted for renal or hepatic impairment.
• Injectable form – 1 g intravenously every 12 hours for severe infections such as meningitis; infusion over 30–60 minutes.
• Ophthalmic drops (.5 % solution) – one drop in the affected eye every 2 hours for the first 24 hours, then taper to 4 times daily until resolution.

Missed dose: Take the missed dose as soon as remembered unless it is close to the time of the next scheduled dose; do not double‑dose.

Overdose: Symptoms may include severe bone‑marrow suppression, hepatic dysfunction, or gastrointestinal distress. Seek immediate medical attention; treatment is supportive, with possible use of granulocyte colony‑stimulating factor (G‑CSF) for severe neutropenia.

Precautions:

• Take tablets with a full glass of water; food does not significantly affect absorption.
• Avoid alcohol excess, as it can worsen hepatic side effects.
• Patients with pre‑existing liver disease should have baseline liver function tests and periodic monitoring.
