What common side effect of antivirals should be monitored during treatment?

Monitoring liver function abnormalities is crucial during antiviral treatment because many antiviral agents can exert hepatotoxic effects. Drugs such as certain nucleoside analogs and non-nucleoside reverse transcriptase inhibitors have been known to cause elevation in liver enzymes, which can indicate liver injury. Regular assessment of liver function tests (LFTs) helps healthcare providers identify any potential complications early, allowing for timely intervention.

While cardiac arrhythmias, nephrotoxicity, and fatigue can also occur with specific antiviral agents, they are not as universally associated with this class of medications as liver function abnormalities. Therefore, consistent monitoring of liver function is a standard practice to ensure patient safety and manage any adverse effects effectively during antiviral therapy.
