What is normal phenytoin level?

Answer 1

The normal therapeutic range for phenytoin levels in the blood typically falls between 10 to 20 micrograms per milliliter (mcg/mL). Levels below 10 mcg/mL may indicate subtherapeutic dosing, while levels above 20 mcg/mL can increase the risk of toxicity. It's important to monitor these levels regularly, especially in patients on chronic therapy. Always consult a healthcare professional for individualized information and guidance.
