Lab monitoring on Acyclovir: which tests and how often
Many chronic medications including Acyclovir (Acyclovir) come with a recommended laboratory monitoring schedule — baseline labs before starting, follow-up checks at defined intervals, and additional tests if symptoms or risk factors change. Knowing what is monitored, why and how often takes the mystery out of routine appointments at 200mg, 400mg, 800mg.
Tests typically monitored on Acyclovir
According to the prescribing information for Acyclovir, the standard monitoring panel for Acyclovir usually includes: liver function (ALT, AST), kidney function (creatinine, eGFR), electrolytes (potassium, sodium), and any class-specific markers (e.g. lipid panel, glucose, hormone levels, blood counts) relevant to Nucleoside antiviral. Acyclovir is a guanosine analogue selectively phosphorylated by viral thymidine kinase to its monophosphate form, then by cellular kinases to acyclovir triphosphate.
Frequency and triggers
Baseline labs before starting Acyclovir establish the reference. Follow-up at 4–12 weeks is typical for most chronic medications, then annually if stable. More frequent monitoring is triggered by dose changes, new symptoms, intercurrent illness, or other interacting medications added to the regimen at 200mg, 400mg, 800mg.
