What lab value should be monitored for patients on anticonvulsants like Dilantin and Depakote?

• A. Calcium levels
• B. Complete blood count (CBC)
• C. Blood glucose levels
• D. Liver enzyme levels

Answer: (B)

When patients are on anticonvulsants like Dilantin (phenytoin) and Depakote (valproic acid), it is crucial to monitor their complete blood count (CBC) due to the potential hematological side effects associated with these medications. Phenytoin can lead to blood dyscrasias, including leukopenia, thrombocytopenia, and macrocytic anemia, particularly in chronic use. Regular monitoring of the CBC allows for early detection of these potentially serious conditions, which can inform timely interventions if necessary. Valproic acid is also known to have similar risks and can affect platelet counts, increasing the importance of regularly checking the CBC in patients taking this medication. Therefore, monitoring the complete blood count is essential to ensure that any adverse effects on hematologic function are identified and addressed promptly, making it the most relevant lab value to watch in this context. This vigilance helps manage the overall safety and effectiveness of treatment in patients on these anticonvulsants.
