Shared Safety Flags

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

Letrozole + Tamoxifen
Monitor

Unlike anastrozole, letrozole does not appear to significantly reduce endoxifen concentrations. However, combining a SERM with an aromatase inhibitor can lead to excessive estrogen suppression. Use with caution and monitor estradiol levels and symptoms.
