Before Using This MedicineIn 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:
