Generic Chloramphenicol

Introduction

Chloramphenicol is an antibiotic that inhibits bacterial protein synthesis and is used for serious infections when other agents are unsuitable. In the United Kingdom it is restricted to specific indications because of safety concerns, but it remains valuable for certain life‑threatening or resistant infections. The active compound is chloramphenicol, and the medication belongs to the broad group of antibiotics. Occasionally it is employed in ophthalmic or topical formulations for bacterial eye infections.

What is Chloramphenicol?

Chloramphenicol is the generic version of the original brand Chloromycetin, containing the same active compound chloramphenicol. It is a broad‑spectrum antibiotic originally discovered in the 194s from Streptomyces venezuelae. The drug is available as oral tablets, injectable solution, and ophthalmic drops. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Chloramphenicol Works

Chloramphenicol binds to the 50S ribosomal subunit of susceptible bacteria, blocking the peptidyl transferase activity essential for peptide bond formation. This halts bacterial protein synthesis, leading to a bacteriostatic effect that prevents bacterial growth. The drug reaches therapeutic concentrations within 2–4 hours after oral administration, distributes widely into tissues and fluids, and is eliminated primarily by hepatic metabolism (glucuronidation) followed by renal excretion. The half‑life averages 1.5–3 hours in healthy adults.

Conditions Treated with Chloramphenicol

• Serious systemic infections caused by susceptible organisms (e.g., Haemophilus influenzae, Streptococcus pneumoniae, certain Staphylococcus spp.) when first‑line agents are contraindicated.
• Meningitis caused by susceptible Haemophilus or Streptococcus species, especially in patients allergic to β‑lactam antibiotics.
• Typhoid fever (Salmonella Typhi) in regions with multidrug‑resistant strains.
• Bacterial conjunctivitis and corneal ulcers where topical chloramphenicol eye drops are indicated.

In the UK, the incidence of multidrug‑resistant meningitis and typhoid is low, but chloramphenicol remains reserved for cases where susceptibility testing confirms its efficacy or where alternative therapies are unsuitable.

Who is Chloramphenicol For?

• Adults with severe infections where standard antibiotics cannot be used due to allergy, resistance, or drug interactions.
• Patients with confirmed susceptibility of the causative organism to chloramphenicol (laboratory testing required).
• Individuals requiring ophthalmic therapy for bacterial eye infections unresponsive to other topical agents.

Chloramphenicol is not appropriate for patients with a known history of bone‑marrow suppression, porphyria, or those who are pregnant or breastfeeding unless the benefit outweighs the risk, as evaluated by a qualified clinician.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset – nausea, vomiting, abdominal pain.
• Mild reversible neutropenia – transient reduction in white‑blood‑cell count, usually dose‑related.

Rare

• Aplastic anemia – irreversible bone‑marrow failure; risk is unpredictable and not dose‑dependent.
• Gray syndrome in newborns – manifests as cyanosis, abdominal distension, and metabolic acidosis when chloramphenicol accumulates.

Serious

• Severe bone‑marrow suppression leading to pancytopenia, infection, and bleeding.
• Hypersensitivity reactions – Stevens‑Johnson syndrome, toxic epidermal necrolysis.

Drug–drug interactions

• Cytochrome P450 inhibitors (e.g., erythromycin, clarithromycin) can increase chloramphenicol plasma levels, heightening toxicity risk.
• Warfarin – chloramphenicol may potentiate anticoagulant effect; INR monitoring is advised.
• Lithium – concurrent use may raise lithium concentrations, requiring serum level checks.

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

Practical Use: Dosing, Missed Dose, Overdose

• Standard oral dosing for adults: 500 mg every 6 hours (total 2 g/day) for systemic infections; dosage may be adjusted for renal or hepatic impairment.
• Injectable dosing: 50 mg/kg loading dose, then 25 mg/kg every 6 hours.
• Ophthalmic drops: 1 % chloramphenicol solution, one drop in the affected eye every 2 hours for the first 24 hours, then every 4 hours.

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

Overdose – Symptoms may include severe nausea, vomiting, abdominal pain, and hematologic abnormalities. Seek immediate medical attention; treatment is supportive, with possible use of activated charcoal if presentation is early.

Practical precautions – Avoid alcohol while taking chloramphenicol as it may exacerbate hepatic toxicity. Food does not significantly affect absorption, so tablets may be taken with or without meals. Patients with liver disease should have liver function monitored regularly.

FAQ

• Is Chloramphenicol available in both brand‑name and generic forms in the UK?
  Yes. The original brand name is Chloromycetin, while generic chloramphenicol contains the same active ingredient and is usually less expensive.

• Does Chloramphenicol require cold storage?
  No. Chloramphenicol tablets and injectables should be stored at controlled room temperature (15‑30 °C) away from moisture and direct sunlight. Ophthalmic drops may be stored in a cool, dry place but do not need refrigeration.

• What does the tablet appearance look like?
  Generic chloramphenicol tablets are typically white, round, and film‑coated, containing inactive excipients such as lactose and magnesium stearate. Specific branding may vary by supplier.

• Can I travel internationally with chloramphenicol in my possession?
  When traveling, keep the medication in its original packaging with a copy of the prescription or a legitimate import permit. Some countries impose restrictions on antibiotics, so verify local regulations before arrival.

• Are there differences in formulation between regions (e.g., EU vs. Asia)?
  Formulations may differ slightly in excipients or packaging due to regional regulatory requirements. However, the active compound concentration (500 mg per tablet) remains standard across approved products.

• Is chloramphenicol listed on any drug‑testing panels for athletes?
  Chloramphenicol is not a prohibited substance by major anti‑doping agencies, but athletes should disclose any medication use to team medical staff to avoid inadvertent violations.

• What historic events led to chloramphenicol’s restricted use?
  In the 196s, reports of aplastic anemia and gray syndrome prompted stricter monitoring and limited its role to cases where alternative antibiotics are ineffective or contraindicated.

• How does chloramphenicol compare with newer broad‑spectrum antibiotics?
  Newer agents such as carbapenems have broader activity and lower risk of bone‑marrow toxicity, but chloramphenicol retains value against certain resistant organisms and in resource‑limited settings.

• Is there a known interaction between chloramphenicol and herbal supplements?
  Some herbal products (e.g., St. John’s wort) induce cytochrome P450 enzymes and could potentially lower chloramphenicol levels, reducing efficacy. Disclosure of all supplements is advisable.

• What are the legal requirements for personal import of chloramphenicol into the UK?
  The UK permits personal import of a three‑month supply for personal use, provided the medication is for a legitimate medical purpose and accompanied by a prescription or medical clearance. Importation must comply with MHRA regulations.
