Phenytoin Toxicity

Excerpt

Since its discovery in 1908, phenytoin has become one of the most well-studied anticonvulsants. With an average monthly cost of $30, it has also become one of the most widely used anticonvulsants, listed on the World Health Organization’s List of Essential Medicines. However, with its narrow therapeutic index and its pervasive daily use, considering potential phenytoin overdose or toxicity from chronic use is key to early management and prevention of further toxicity.
