Selective serotonin reuptake inhibitor (SSRI)
Sertraline and blood test results
Routine blood tests sometimes shift in unexpected ways during treatment with a chronic medication. Sertraline (Sertraline) at 25mg, 50mg, 100mg 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 Sertraline
Possible lab effects of Sertraline 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. Sertraline selectively blocks the reuptake of serotonin (5-HT) by the presynaptic neuron, increasing the concentration of serotonin in the synaptic cleft. Most changes are mild and reversible; significant shifts trigger dose adjustment or further investigation.
Routine monitoring
According to the prescribing information for Sertraline, baseline labs before starting Sertraline 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 Sertraline dosing — the test instructions take precedence.
