Recommended Dosage

For treatment of adults with CABP, the recommended dosage of XENLETA is described in Table 1 below. For patients with severe hepatic impairment, dosage adjustment is required [see Dosage and Administration (2.2)].

Dosage Adjustment for Patients with Hepatic Impairment

Monitor patients with hepatic impairment for adverse reactions associated with XENLETA Injection and Tablets throughout the treatment period [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

XENLETA Injection

Reduce the dosage of XENLETA Injection to 150 mg infused intravenously over 60 minutes every 24 hours for patients with severe hepatic impairment (Child-Pugh Class C). No dosage adjustment of XENLETA Injection is needed for patients with mild (Child-Pugh Class A) or moderate (Child-Pugh Class B) hepatic impairment.

XENLETA Tablets

XENLETA Tablets have not been studied in and are not recommended for patients with moderate (Child-Pugh Class B) or severe (Child-Pugh Class C) hepatic impairment. No dosage adjustment of XENLETA Tablets is needed for patients with mild hepatic impairment (Child-Pugh Class A).

Important Administration Instructions

XENLETA Injection

Administer XENLETA Injection by intravenous infusion over 60 minutes. Must dilute in a 250 mL solution of 10 mM citrate buffered 0.9% sodium chloride for injection supplied with XENLETA Injection before use [see Dosage and Administration (2.4)].

XENLETA Tablets

Take XENLETA Tablets at least 1 hour before a meal or 2 hours after a meal. Swallow XENLETA Tablets whole with water (6 to 8 ounces). Do not crush or divide XENLETA Tablets [see Clinical Pharmacology (12.3)].

Preparation of XENLETA Injection for Intravenous Infusion

• Dilute the entire 15 mL vial of XENLETA Injection into the diluent bag supplied with XENLETA injection that contains 250 mL of 10 mM citrate buffered 0.9% sodium chloride.
• Use aseptic technique when adding XENLETA Injection into the diluent bag. Mix thoroughly.
• Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Use the diluent bag only if the solution is clear and the container is undamaged.
• Do not use the diluent bag in series connections.
• Do not add other additives to the diluent bag because their compatibilities with XENLETA Injection have not been established.

Storage of XENLETA Injection After Dilution

After dilution, XENLETA Injection can be stored for up to 24 hours at room temperature and up to 48 hours when refrigerated at 2°C to 8°C (36°F to 46°F).
