4 Drug and Medication Information
4.1 Drug Indication

Xenleta is indicated for the treatment of community-acquired pneumonia (CAP) in adults when it is considered inappropriate to use antibacterial agents that are commonly recommended for the initial treatment of CAP or when these have failed.

Consideration should be given to official guidance on the appropriate use of antibacterial agents.
