Chloramphenicol

What is Chloramphenicol?

Chloramphenicol is a prescription antibiotic used to treat serious bacterial infections. It belongs to a group of medicines known as broad-spectrum antibiotics, meaning it can act against many different types of bacteria.

Healthcare professionals may prescribe chloramphenicol for infections such as:

Severe bacterial infections when other antibiotics are not suitable

Certain eye infections

Typhoid fever and related infections

Meningitis caused by susceptible bacteria

Serious respiratory or systemic infections

Because of potential serious side effects, chloramphenicol is usually reserved for situations where other antibiotics may not be effective or appropriate.

Available formulations and strengths

Chloramphenicol may be available in different dosage forms depending on medical use:

Oral capsules or tablets

Intravenous injections (hospital use)

Eye drops

Ophthalmic ointments

Specific strengths vary depending on the manufacturer and regulatory approvals in different countries.

What is the Recommended Dosage of Chloramphenicol?

The appropriate dosage of chloramphenicol must be determined by a licensed healthcare professional.

Factors influencing dosage

Healthcare providers consider several factors when determining the dose:

Type and severity of infection

Patient age

Body weight

Liver and kidney function

Route of administration (oral, injection, or eye preparation)

Available dosage forms

Chloramphenicol may be administered as:

Oral capsules or tablets

Injectable formulations in hospital settings

Ophthalmic drops or ointments for eye infections

Because this medication can have significant side effects, treatment should only occur under careful medical supervision.

How Chloramphenicol Works

Chloramphenicol works by inhibiting bacterial protein synthesis.

Bacteria require proteins to grow, multiply, and maintain their essential functions. Chloramphenicol blocks specific bacterial enzymes involved in protein production. As a result:

Bacterial growth slows or stops

The immune system can eliminate the infection more effectively

This antibiotic helps control bacterial infections but does not treat viral illnesses such as colds or influenza.
