Neurontin and blood test results
Routine blood tests sometimes shift in unexpected ways during treatment with a chronic medication. Neurontin (Gabapentin) at 100mg, 300mg, 400mg, 600mg, 800mg 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 Neurontin
Possible lab effects of Gabapentin 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. Gabapentin binds the alpha-2-delta auxiliary subunit of voltage-gated calcium channels in the central nervous system, reducing presynaptic calcium influx and the release of excitatory neurotransmitter… Most changes are mild and reversible; significant shifts trigger dose adjustment or further investigation.
Routine monitoring
According to the prescribing information for Gabapentin, baseline labs before starting Neurontin and periodic monitoring during treatment are recommended for many medications in Neurological Medications. The frequency depends on the agent and on individual risk factors. Fasting requirements for specific tests are independent of Neurontin dosing — the test instructions take precedence.
