How are CYP2D6 and Wechseljahre related?

CYP2D6 is an enzyme that metabolizes many drugs, including some antidepressants (e.g., paroxetine, venlafaxine) used off-label for menopausal hot flashes. Genetic variants in CYP2D6 can alter drug metabolism, potentially affecting efficacy or side effects. However, there is no well-established direct link between CYP2D6 and the hormonal changes of menopause itself. Most consumer DNA tests (including MyBody-X) do not include CYP2D6 markers; clinical pharmacogenetic testing is more comprehensive. Evidence: mechanistic/unclear. Caveat: do not adjust medication based on a consumer genetic test without consulting a physician.
