Does long-term chloramphenicol cause anaemia in Malawi?

Common clinical practice in many tropical paediatric departments is that chloramphenicol courses are limited to 2 weeks due to concerns about anaemia. However, this approach is not supported by current research and animal models. We used chloramphenicol for 6 weeks in 146 children with septic arthritis. All the children improved clinically. Most children were anaemic on presentation (mean haemoglobin [Hb] 8.43 SD 1.9), but the anaemia improved rapidly with clinical resolution of the infection and was maintained at 6 months after presentation (mean Hb 10.57 SD 1.86)
