Which drugs require liver function monitoring when prescribed?

• A. Statins, metformin, and acetaminophen
• B. Diuretics and insulin
• C. Antibiotics and anticoagulants
• D. Beta blockers

Answer: (A)

Medications that affect the liver or rely on the liver for metabolism require checking liver function tests to catch hepatotoxicity early and guide safe use. Statins can cause elevations in liver enzymes, so a baseline LFT is typically obtained before starting and then checked again if symptoms develop or during ongoing therapy. Acetaminophen is well known for potential serious liver injury, especially with overdose or chronic high dosing, so liver function assessment is important when it’s used long-term or in patients with risk factors, along with strict counseling on dosing and alcohol avoidance. Metformin isn’t directly hepatotoxic, but liver impairment increases the risk of lactic acidosis, so evaluating hepatic function helps determine suitability before starting and monitoring during treatment, with the option to discontinue if hepatic function worsens. Together, these drugs involve liver-related monitoring, whereas the other drug classes commonly do not require routine LFT monitoring as part of standard practice.
