Linezolid was approved for clinical use for methicillin resistant Staphylococcus aureus and vancomycin-resistant Enterococci. Additionally it is used in the management of drug resistant tuberculosis. It is well-tolerated however bone marrow suppression and neuropathies may occur in patients taking this antibiotic for more than 2 weeks. Black discoloration and black hairy tongue (BHT) due to linezolid is rarely reported. We report two cases of BHT. Two patients of drug resistant pulmonary tuberculosis developed benign hairy tongue with linezolid 600mg per day. In both the cases black colored/hairy tongue was reported within 2-3 weeks of linezolid treatment. Both patients improved after withdrawal of linezolid. Subsequent reintroduction of linezolid with good oral hygiene was well tolerated and both patients completed the treatment of 2 years duration without any recurrence. Black discoloration and BHT is a rare but transient adverse reaction with linezolid. Reintroduction of linezolid with good oral hygiene is well tolerated.
