Abstract: Objective To analyze new adverse reactions-double knee joint pain-caused by linezolid in order to provide reference for related clinical pharmaceutical care. Methods The causes of double knee joint pain in a 39-year-old female patient were analyzed who had suffered mycobacterium abscess infection after resection of intervertebral schwannoma and taken oral linezolid tablets 0.6 g, oral clarithromycin tablets 0.5 g, and oral moxifloxacin tablets 0.4 g. Drugs that might have caused joint pain were identified using the Naranjo’s assessment scale. Results The pain and discomfort of knee joint in both legs were attributed to linezolid, and considered new adverse reactions caused by linezolid. Conclusion Pharmacists should be alert to new adverse reactions caused by linezolid and give high-quality pharmaceutical care while watching out for such marrow suppression as leukopenia caused by linezolid.
