b. monitor drug levels, actions, and side effects.
When two drugs that are both-bound are taken together, there is a possibility of drug interaction as they may compete for binding sites. This can result in an increased concentration of one or both drugs in the blood, leading to potential adverse effects. Therefore, the primary care NP should closely monitor the patient for drug levels, actions, and side effects to ensure safety and efficacy of treatment. Increasing the doses of both drugs or teaching the patient to increase protein intake is not an appropriate solution, and staggering the doses 1 hour apart may not be sufficient to prevent potential drug interactions.
