Which laboratory test would identify an adverse effect of dantrolene sodium?

• A. Kidney function tests
• B. Electrolyte panel
• C. Complete blood count
• D. Liver function tests

Answer: (D)

Adverse effects of dantrolene sodium include potential hepatotoxicity, so the lab test that best identifies this risk is liver function testing. Dantrolene can cause liver injury, especially with longer use or higher doses, which may show up as elevated liver enzymes (AST/ALT), increased bilirubin, or other hepatic abnormalities. Regular liver function tests before starting therapy and during treatment help detect hepatotoxicity early and guide decisions about continuing or stopping the drug. Other tests—kidney function, electrolyte panels, and complete blood counts—monitor different systems and do not specifically reveal dantrolene-related liver injury.
