Lab monitoring on Desyrel: which tests and how often
Many chronic medications including Desyrel (Trazodone) 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 50mg, 100mg, 150mg, 300mg.
Tests typically monitored on Desyrel
According to the prescribing information for Trazodone, the standard monitoring panel for Desyrel 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 Anti-Depressants. Trazodone is classified as a serotonin antagonist and reuptake inhibitor (SARI).
Frequency and triggers
Baseline labs before starting Desyrel 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 50mg, 100mg, 150mg, 300mg.
