Description

Chloramphenicol (klor-am-FEN-i-kole) is used in the treatment of infections caused by bacteria. It works by killing bacteria or preventing their growth.

Chloramphenicol is used to treat serious infections in different parts of the body. It is sometimes given with other antibiotics. However, chloramphenicol should not be used for colds, flu, other virus infections, sore throats or other minor infections, or to prevent infections.

Chloramphenicol should only be used for serious infections in which other medicines do not work. This medicine may cause some serious side effects, including blood problems and eye problems. Symptoms of the blood problems include pale skin, sore throat and fever, unusual bleeding or bruising, and unusual tiredness or weakness. You and your doctor should talk about the good this medicine will do as well as the risks of taking it .

Chloramphenicol is available only with your doctor's prescription, in the following dosage forms:



Before Using This Medicine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For chloramphenicol, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to chloramphenicol. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy—Chloramphenicol has not been shown to cause birth defects in humans. However, use is not recommended within a week or two of your delivery date. Chloramphenicol may cause gray skin color, low body temperature, bloated stomach, uneven breathing, drowsiness, pale skin, sore throat and fever, unusual bleeding or bruising, unusual tiredness or weakness, or other problems in the infant.

Breast-feeding—Chloramphenicol passes into the breast milk and has been shown to cause unwanted effects, such as pale skin, sore throat and fever, unusual bleeding or bruising, unusual tiredness or weakness, or other problems in nursing babies. It may be necessary for you to take another medicine or to stop breast-feeding during treatment. Be sure you have discussed the risks and benefits of the medicine with your doctor.

Children—Newborn infants are especially sensitive to the side effects of chloramphenicol because they cannot remove the medicine from their body as well as older children and adults.

Older adults—Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of chloramphenicol in the elderly with use in other age groups.

Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking chloramphenicol, it is especially important that your health care professional know if you are taking any of the following:
