Lefamulin, sold under the brand name Xenleta, is an antibiotic medication used it to treat adults with community-acquired bacterial pneumonia.[5][6] It is taken by mouth or by injection into a vein.[5][6][7]

Relatively common side effects include diarrhea, nausea, pain at the site of injection, and liver inflammation.[5][8] It is a pleuromutilin antibiotic that inhibits the large subunit of bacterial ribosomes.[9][10]

Lefamulin was approved for medical use in the United States in August 2019,[5][11] and in the European Union in July 2020.[3]
