Usage Instructions

How Should This Medication Be Used

Chloramphenicol injection comes as a liquid to be injected into a vein by a doctor or nurse in a hospital. It is usually given every 6 hours. The length of your treatment depends on the type of infection being treated. After your condition improves, your doctor may switch you to another antibiotic that you can take by mouth to complete your treatment. You should begin to feel better during the first few days of treatment with chloramphenicol injection. If your symptoms do not improve or get worse, tell your doctor. Use chloramphenicol injection for as long as your doctor tells you, even if you feel better. If you stop using chloramphenicol injection too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
