What lab values should be monitored for tamoxifen?

When a patient is on tamoxifen, it is important to monitor liver function tests (LFTs), including AST, ALT, and bilirubin, due to the potential for hepatotoxicity. Additionally, monitoring lipid profiles is advised, as tamoxifen can affect cholesterol levels. Routine checks for endometrial health, such as transvaginal ultrasound, may also be appropriate due to the drug's association with uterine changes. Regular assessments of bone density may be considered, especially in postmenopausal women, to evaluate any impact on bone health.
