A client taking duloxetine discloses heavy alcohol use. What should the nurse do first?

In this scenario, the most appropriate action is to report the client's heavy alcohol consumption to the primary health care provider. Clients taking duloxetine are at an increased risk for adverse effects when combined with alcohol, including potential exacerbation of side effects such as sedation, increased risk of liver damage, and heightened serotonin syndrome. Given that duloxetine is often prescribed for mood disorders and pain management, it's crucial for the healthcare team to be aware of any behaviors that could undermine the treatment plan or pose risks to the client's health.

By reporting the client's alcohol use, the nurse ensures that the primary health care provider can assess the situation, modify treatment options if necessary, and provide appropriate intervention. This step is vital for safeguarding the client's well-being, as alcohol can significantly impact both the effectiveness of duloxetine and the client's mental health status.

The other options do not address the immediate need for intervention and oversight in light of significant alcohol use in a client on this medication. Teaching relaxation exercises or referring to a dual diagnosis program may be beneficial later but do not prioritize the urgent requirement for medical input given the interaction between alcohol and the medication. Sharing information at a treatment conference is also important, but it does not provide the immediate response necessary in this scenario.
