Phenytoin blood levels should typically be checked at least once every 6 to 12 months for patients on stable doses. However, levels should be monitored more frequently—such as every 2 to 3 weeks—when initiating therapy, adjusting doses, or during periods of changes in health status or medication interactions. Regular monitoring ensures that the drug remains within the therapeutic range and minimizes the risk of toxicity or seizure recurrence. Always follow the specific recommendations of a healthcare provider.

Lactic acid levels should be checked based on the clinical context and the patient's condition. In critically ill patients or those with suspected sepsis, it may be monitored frequently, such as every 1-2 hours, until stabilization is achieved. For patients with known lactic acidosis or those undergoing treatment for conditions that can elevate lactic acid, levels may be checked daily or as needed. Ultimately, the frequency should be guided by the healthcare provider's judgment and the patient's response to treatment.
