Linezolid is an
antibiotic in the
oxazolidinone family that works as a
bacterial protein synthesis inhibitor. It is used for the
treatment of Gram-positive, multidrug-resistant
bacteria.
Adverse effects of
linezolid include
bone marrow suppression, peripheral or
optic neuropathy, and, less commonly,
lactic acidosis.
Lactic acidosis usually occurs as a result of cardiopulmonary failure or
sepsis, but it is sometimes caused by
drugs, such as
linezolid, and
treatment of such
lactic acidosis involves cessation of the
drug. We
report a case of
lactic acidosis caused by the use of
linezolid for the
treatment of persistent
methicillin-resistant Staphylococcus aureus bacteremia, which occurred after endoscopic
sclerotherapy of gastic
varices.
