Kemnicol 250mg Capsule contains Chloramphenicol, a broad-spectrum antibiotic effective against a wide range of Gram-positive and Gram-negative bacterial infections. It acts by inhibiting bacterial protein synthesis through binding to the 50S ribosomal subunit, thereby preventing peptide bond formation and bacterial growth. Kemnicol is indicated for the treatment of serious infections such as typhoid fever, meningitis, rickettsial infections, and certain respiratory tract infections where other antibiotics may be ineffective or contraindicated. This medication is administered orally, with the dosage and duration dependent on the type and severity of the infection, as well as patient-specific factors such as age and renal function. Due to its potential for serious adverse effects, including bone marrow suppression and aplastic anemia, Chloramphenicol should be used under strict medical supervision with regular monitoring of blood counts. It is contraindicated in patients with known hypersensitivity to Chloramphenicol and should be used cautiously in neonates and individuals with hepatic or renal impairment. Patients are advised to complete the full prescribed course to prevent resistance development. Common side effects may include gastrointestinal disturbances, headache, and reversible bone marrow suppression. Kemnicol 250mg Capsule is a critical therapeutic option reserved for infections unresponsive to first-line agents.
