What is the suggested liver function monitoring for tigecycline?

How often should liver function be monitored on tigecycline?

Tigecycline can cause liver enzyme elevations. The suggested monitoring is to check liver function tests (including ALT, AST, and bilirubin) regularly during treatment, with more frequent testing if baseline liver abnormalities are present or if liver test results start to rise.

What specific liver tests are usually followed?

Clinicians typically monitor:
- Serum ALT and AST (transaminases)
- Total bilirubin (and sometimes direct bilirubin depending on local practice)
These tests help detect drug-related hepatocellular injury and cholestatic patterns.

When should monitoring be increased or tigecycline stopped?

Monitoring should be tightened if liver enzymes increase from baseline, and treatment should be reconsidered if results suggest clinically significant liver injury. In practice, this means additional labs (and clinical assessment) sooner when there are rising transaminases or bilirubin.

Does the recommendation change for patients with liver disease?

Yes. For patients with pre-existing hepatic impairment or abnormal baseline liver tests, clinicians generally start with closer laboratory follow-up and monitor more frequently during therapy.
