Cymbalta and blood test results
Routine blood tests sometimes shift in unexpected ways during treatment with a chronic medication. Cymbalta (Duloxetine) at 20mg, 30mg, 60mg 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 Cymbalta
Possible lab effects of Duloxetine 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. Cymbalta inhibits the reuptake of both serotonin and norepinephrine at the synapse. Most changes are mild and reversible; significant shifts trigger dose adjustment or further investigation.
Routine monitoring
According to the prescribing information for Duloxetine, baseline labs before starting Cymbalta and periodic monitoring during treatment are recommended for many medications in Anti-Depressants. The frequency depends on the agent and on individual risk factors. Fasting requirements for specific tests are independent of Cymbalta dosing — the test instructions take precedence.
