Women have a higher risk of breast cancer recurrence if they take tamoxifen along with paroxetine, fluoxetine, or sertraline... but NOT citalopram,
escitalopram, or fluvoxamine. .....About 30% of women on tamoxifen also take an SSRI for depression or hot flashes. FDA will add new warnings..and Medco is alerting physicians if a woman on tamoxifen gets paroxetine, fluoxetine, or sertraline. Suggest using one of the other SSRIs or venlafaxine if needed for depression or hot flashes.
