Selective serotonin reuptake inhibitor (SSRI)
Citalopram and blood test results
Routine blood tests sometimes shift in unexpected ways during treatment with a chronic medication. Citalopram (Citalopram) at 10mg, 20mg, 40mg may directly alter certain lab parameters, indirectly affect others through its mechanism, or interfere with the assay itself in rare cases. Knowing what is normal, what is monitored and what is artefact prevents unnecessary worry.
Lab effects of Citalopram
Possible lab effects of Citalopram are listed in the prescribing information. They typically reflect the medication's mechanism: changes in liver enzymes, kidney function markers, blood counts, electrolytes, glucose or lipids depending on the agent. Citalopram selectively inhibits the serotonin reuptake transporter, increasing synaptic serotonin availability with limited affinity for noradrenaline transporters or other receptors. Most changes are mild and reversible; significant shifts trigger dose adjustment or further investigation.
Routine monitoring
According to the prescribing information for Citalopram, baseline labs before starting Citalopram and periodic monitoring during treatment are recommended for many medications in Selective serotonin reuptake inhibitor (SSRI). The frequency depends on the agent and on individual risk factors. Fasting requirements for specific tests are independent of Citalopram dosing — the test instructions take precedence.
