Shared Safety Flags

2x 2 hepatotoxic compounds (Anastrozole, Tamoxifen). Liver damage risk significantly increased. Include liver support (TUDCA/NAC) and monitor ALT/AST.
2x 2 compounds share the pct-agent safety flag (Anastrozole, Tamoxifen). Monitor accordingly.
2x 2 compounds share the teratogenic safety flag (Anastrozole, Tamoxifen). Monitor accordingly.

Anastrozole + Tamoxifen
Avoid

The ATAC trial and subsequent pharmacokinetic studies demonstrated that anastrozole significantly reduces plasma concentrations of endoxifen, tamoxifen's primary active metabolite, thereby reducing its effectiveness. This combination should be avoided. If aromatase inhibition is needed alongside a SERM, consider alternative combinations.
