ICD-10: T36.2X4

The ICD-10-CM code T36.2X4 pertains to cases of poisoning by the chloramphenicol group of antibiotics, specifically categorized as "undetermined." This classification is part of a broader set of codes that address various types of poisoning, adverse effects, and underdosing related to medications.

Clinical Description

Overview of Chloramphenicol

Chloramphenicol is a broad-spectrum antibiotic that was historically used to treat serious infections, particularly those caused by bacteria resistant to other antibiotics. It works by inhibiting bacterial protein synthesis. However, due to its potential for serious side effects, including aplastic anemia and gray baby syndrome, its use has become limited and is often reserved for specific situations where other antibiotics are ineffective or contraindicated.

Poisoning by Chloramphenicol

The code T36.2X4 specifically indicates cases where an individual has been poisoned by chloramphenicol, but the circumstances surrounding the poisoning are classified as "undetermined." This could imply that the exact cause of the poisoning—whether it was accidental, intentional, or due to an adverse reaction—has not been clearly established.

Symptoms and Clinical Presentation

Symptoms of chloramphenicol poisoning can vary widely depending on the dose and the individual's health status. Common symptoms may include:

• Nausea and vomiting
• Diarrhea
