Which of the following is an appropriate intervention for monitoring while on SSRIs?

Monitoring liver function tests is particularly relevant when a patient is on selective serotonin reuptake inhibitors (SSRIs) because many SSRIs are metabolized through the liver. This metabolic pathway makes the liver vulnerable to drug-induced changes, and some patients may develop liver dysfunction as a result of taking these medications. Therefore, assessing liver function can help identify potential adverse effects early, ensuring timely intervention if any liver abnormalities arise.

While monitoring blood glucose levels, BMI, and thyroid function can be important in specific patient populations and conditions, they are not routinely required for all patients on SSRIs. Blood glucose monitoring is more critical in patients with diabetes or those at risk for hyperglycemia. Monitoring BMI can be necessary in the context of weight changes associated with certain SSRIs, but it's not a standard procedure for all patients. Thyroid function is relevant in the context of patients with known thyroid disorders or when there are clinical indications of thyroid dysfunction. Thus, liver function tests stand out as a critical aspect of monitoring the safe use of SSRIs in general practice.
