What is the therapeutic level range for Dilantin?

The therapeutic level range for Dilantin (phenytoin) is crucial for ensuring the medication's effectiveness while minimizing the risk of toxicity. The correct range of 10-20 mcg/mL reflects the concentration at which Dilantin is effective for seizure control. Maintaining the serum levels within this range helps to optimize its anti-seizure activity and allows for effective management of conditions such as epilepsy. Levels below 10 may lead to inadequate seizure control, while levels above 20 may increase the risk of adverse effects such as ataxia, nystagmus, or even more severe consequences. Understanding this therapeutic range is essential for safe medication management and for monitoring patient treatment effectively.
