Final answer:
The greatest priority to address phenytoin's (Dilantin) narrow therapeutic index is to closely monitor the drug levels in the patient's blood, watch for potential drug interactions, and educate patients on proper medication adherence.
Step-by-step explanation:
When addressing phenytoin's (Dilantin) narrow therapeutic index, the greatest priority is to closely monitor the drug levels in the patient's blood. This is because phenytoin has a relatively small range between its therapeutic and toxic levels. Regular blood tests are necessary to ensure the drug is within the optimal range and to prevent adverse effects.
Another important consideration is to monitor for potential drug interactions, as phenytoin can interact with other medications, affecting its effectiveness or increasing the risk of side effects. Healthcare professionals need to be aware of any concomitant medications the patient is taking and adjust the dosage accordingly.
Lastly, it is crucial to educate patients about the importance of adhering to their medication regimen and to communicate any changes or concerns regarding their treatment to their healthcare provider. Skipping doses or making changes to the dosage without medical guidance can lead to fluctuations in drug levels and compromise the therapeutic efficacy of phenytoin.
