Generic Chloromycetin

Introduction

Chloromycetin is an antibacterial medication containing the active compound chloramphenicol. It belongs to the broad‑spectrum antibiotic group and is used in the United Kingdom for infections where other agents are unsuitable or ineffective. Originally developed in the 194s, chloramphenicol has retained a niche role because of its ability to penetrate body fluids and tissues that many antibiotics cannot reach. In the UK, the drug is prescribed for serious bacterial infections such as typhoid fever, meningitis caused by susceptible organisms, and certain eye infections. The product is marketed under the generic name Chloromycetin and is supplied by various international manufacturers that meet UK quality standards.

What is Chloromycetin?

Chloromycetin is the generic version of the original brand‑name drug Chloramphenicol, which was marketed worldwide under names such as Chloromycetin, Roxithromycin‑C, and C‑Cip. The formulation contains the same active molecule, chloramphenicol, and is produced by licensed pharmaceutical companies that follow Good Manufacturing Practice (GMP). As a generic, Chloromycetin offers a cost‑effective alternative to branded products while delivering identical therapeutic activity. Our online pharmacy provides this generic alternative, ensuring access to a high‑quality antibiotic at near‑manufacturer pricing.

How Chloromycetin Works

Chloramphenicol inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit. This binding blocks the peptidyl transferase activity required for peptide bond formation, halting elongation of the nascent protein chain. Because the drug targets a step common to many bacterial species, it exhibits a broad spectrum of activity against Gram‑positive, Gram‑negative, anaerobic, and atypical organisms.

• Onset of action: Clinical effects are usually observed within 24–48 hours of the first dose, reflecting rapid distribution into plasma and extracellular fluids.
• Duration and clearance: Chloramphenicol has a half‑life of 1.5–3 hours in adults with normal liver function. It is primarily metabolised by hepatic glucuronidation and excreted in urine as conjugated metabolites. Dose adjustments are required in severe hepatic impairment because the metabolic pathway can become saturated, leading to accumulation.

Conditions Treated with Chloromycetin

• Typhoid fever (Salmonella Typhi): Oral or intravenous chloramphenicol remains an option when resistance to fluoroquinolones is documented. The drug reaches therapeutic concentrations in the bloodstream and intracellular compartments where Salmonella persists.
• Bacterial meningitis: When causative organisms are known to be susceptible (e.g., Haemophilus influenzae, Neisseria meningitidis), chloramphenicol penetrates the cerebrospinal fluid (CSF) effectively, especially after meningeal inflammation.
• Eye infections (conjunctivitis, keratitis): Ophthalmic preparations containing chloramphenicol are used for bacterial conjunctivitis caused by susceptible Staphylococcus spp. or Streptococcus spp.
• Rickettsial diseases: In cases of epidemic typhus or murine typhus, chloramphenicol provides an alternative to doxycycline when contraindicated.
• Anaerobic infections: For mixed‑flora intra‑abdominal or pelvic infections where anaerobes predominate, chloramphenicol’s activity against Bacteroides fragilis adds therapeutic breadth.

These indications are recognised by the UK Medicines and Healthcare products Regulatory Agency (MHRA) and are reflected in the British National Formulary (BNF) under “chloramphenicol.” The drug’s utility lies in its ability to treat infections that are difficult to manage with first‑line agents, especially when resistance patterns limit other choices.

Who is Chloromycetin For?

• Adults with severe systemic infections where susceptibility testing confirms chloramphenicol sensitivity and alternative antibiotics are unsuitable (e.g., allergy, resistance).
• Patients requiring high CSF penetration, such as those with meningitis caused by chloramphenicol‑sensitive organisms.
• Individuals with limited access to newer antibiotics but who need a reliable, broad‑spectrum agent.
• Travelers returning from endemic regions who develop typhoid fever and have laboratory confirmation of susceptible Salmonella.

Chloromycetin is not recommended for patients with known bone‑marrow disorders, severe hepatic impairment, or a history of aplastic anaemia. Pregnant women and nursing mothers should avoid chloramphenicol because of documented fetal toxicity and potential for neonatal bone‑marrow suppression.

Risks, Side Effects, and Interactions

Common

• Gastro‑intestinal upset: Nausea, vomiting, or diarrhoea occur in up to 10 % of patients.
• Mild reversible bone‑marrow suppression: Transient neutropenia or thrombocytopenia may be observed, especially with prolonged therapy.
• Headache and dizziness: Frequently reported during the initial weeks of treatment.

Rare

• Aplastic anaemia: An irreversible, potentially fatal suppression of haematopoiesis occurring in <1 % of exposed individuals; risk appears unrelated to dose or duration.
• Grey‑baby syndrome: Severe cyanosis and cardiovascular collapse in neonates exposed via breast‑milk; avoidance in lactating mothers is mandatory.
• Hypersensitivity reactions: Rash, pruritus, or, rarely, Stevens‑Johnson syndrome.

Serious

• Severe bone‑marrow failure: Manifesting as pancytopenia, requiring immediate drug discontinuation and haematology support.
• Hepatotoxicity: Elevated transaminases and, in rare cases, hepatic necrosis have been reported with high‑dose or prolonged regimens.
• Serious drug–drug interactions: Concurrent use with warfarin may potentiate anticoagulation; co‑administration with other myelosuppressive agents (e.g., chemotherapy) increases the risk of profound cytopenias.

Patients should promptly report any unexplained bruising, persistent fever, or unusual fatigue while on chloramphenicol.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing (oral): 500 mg every 6 hours for most infections, adjusted to 250 mg every 6 hours in patients with hepatic impairment. Intravenous dosing follows the same mg‑per‑kg schedule (approximately 25 mg/kg/day divided q6h).
• Duration: Typically 7–14 days, guided by clinical response and microbiology results. Longer courses increase the risk of bone‑marrow toxicity.
• Missed dose: Take the forgotten dose as soon as remembered unless the next scheduled dose is within 2 hours; in that case, skip the missed dose and resume the regular schedule. Do not double‑dose.
• Overdose: Symptoms may include severe nausea, vomiting, profound bone‑marrow suppression, and hepatic dysfunction. Seek emergency medical attention; treatment is supportive, with possible use of activated charcoal if ingestion was recent.
• Precautions: Avoid alcohol, as both are metabolised by the liver and can exacerbate hepatotoxicity. Patients with renal failure should have dosing frequency reduced after renal function assessment.

FAQ

• **Can Chloromycetin be stored at temperatures above room temperature?**
  Chloromycetin should be kept at a controlled room temperature of 20–25 °C (68–77 °F). Storing it in hot environments, such as a car glove compartment, may degrade the active ingredient, reducing efficacy.

• **What does the tablet imprint on Chloromycetin look like?**
  Generic chloramphenicol tablets commonly bear a flat “C” on one side and the strength “500 mg” on the other, though imprint designs can vary by manufacturer. Checking the packaging and accompanying leaflet helps confirm authenticity.

• **Is there any difference between European and Asian formulations of chloramphenicol?**
  European formulations generally use lactose or microcrystalline cellulose as fillers, whereas some Asian versions may contain starch‑based excipients. Both meet pharmacopeial, but patients with specific intolerances should review the inactive ingredient list.

• **Can Chloromycetin be taken with oral contraceptives?**
  Chloramphenicol does not induce hepatic enzymes that affect hormonal contraception, so it is unlikely to reduce contraceptive efficacy. Nonetheless, if you experience persistent vomiting, additional contraceptive protection is advisable.

• **What are the legal requirements for personal import of Chloromycetin into the UK?**
  Individuals may import a 3‑month supply for personal use under the UK’s “personal importation” exemption, provided the product is for a legitimate medical need and is not a controlled substance. Customs may request a copy of the prescription or a doctor’s letter.

• **Does Chloromycetin appear on standard drug‑testing panels for athletes?**
  Chloramphenicol is listed under the World Anti‑Doping Agency’s prohibited substances in the “antibiotics” category. Athletes subject to testing should disclose therapeutic use and obtain a Therapeutic Use Exemption (TUE) where applicable.

• **How long does it take for Chloromycetin to be completely eliminated from the body?**
  After cessation, chloramphenicol’s plasma levels fall below detectable limits within 24 hours in individuals with normal liver function. Metabolites may persist for up to 48 hours, but they are pharmacologically inactive.

• **Are there special considerations for patients with G6PD deficiency?**
  Chloramphenicol does not cause oxidative stress in red blood cells, so it is not contraindicated in G6PD‑deficient individuals. However, any haemolytic episodes should be evaluated promptly.

• **Can Chloromycetin be used as a prophylactic agent after potential exposure to typhoid?**
  In rare situations where a close contact of a confirmed case is unable to receive the first‑line vaccine, a short course of chloramphenicol (e.g., 500 mg twice daily for 5 days) may be considered, but only under medical supervision.

• **What packaging does Chloromycetin come in when ordered from abroad?**
  The medication is typically supplied in sealed, tamper‑evident blister packs or bottles, each labeled with batch number, expiry date, and storage instructions. Our pharmacy includes a clear outer envelope to protect the product during transit.
