Tests typically monitored on Anti-Depressants
According to the prescribing information for Amitriptyline, Bupropion, Citalopram, Duloxetine, Escitalopram, Fluoxetine, Mirtazapine, Paroxetine, Sertraline, Trazodone, Venlafaxine, the standard monitoring panel for Anti-Depressants 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. Selective serotonin reuptake inhibitors (SSRIs) are the most common first-line option for depression and anxiety due to their generally favourable side effect profile.
Frequency and triggers
Baseline labs before starting Anti-Depressants 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 10mg, 20mg, 40mg, 30mg, 60mg.
