		Factor Description		Reduced pharmacological effects leading to insufficient efficacy and/or treatment failure.
Mechanism Description		Attenuated pharmacological effects of  Chloramphenicol when combined with Ferrous fumarate

Recommended Action
Management		Patients with preexisting anemia should preferably not receive chloramphenicol due to the drug's depressive effect on bone marrow and reticulocytes. If use is unavoidable, the lowest effective dosage of chloramphenicol should be given. Hematologic response to iron or vitamin B12 therapy should be closely monitored.
