What does a phenytoin level of 7 mcg/mL indicate?

A phenytoin level of 7 mcg/mL indicates that the level is lower than the expected therapeutic range, which typically falls between 10 to 20 mcg/mL for most patients. Phenytoin is an antiepileptic medication used to control seizures, and maintaining a therapeutic level is crucial for ensuring efficacy in seizure management. If the level is below the therapeutic range, it suggests that the medication may not be providing adequate control of seizures, and adjustments to the dosage may be necessary. This understanding of therapeutic ranges is vital in clinical practice to ensure optimal treatment outcomes for patients undergoing seizure management.
