Periodically, various tests may be needed.

Monitoring antiepileptic drug treatment with measurement of the concentration of antiepileptic medications in the blood stream is often used to:

  • Correlate with the effectiveness of treatment
  • Document the patient’s compliance with the prescribed medications
  • Correlate with side effect (s) reported by the patient

Also, complete blood counts may be used to measure any potential adverse effects of the anticonvulsant medications on the bone marrow. Liver function tests may be used to measure any potential adverse effects of the anticonvulsant medication on the liver, while pancreatic enzymes may be used to measure any potential adverse effects of the anticonvulsant on the pancreas.

Kidney function may also be tested to measure the ability of the kidney to clear medications that are predominantly removed by the kidney so that the doses of the anticonvulsant can be tailored for patients with altered kidney function.
