Red Clover Isoflavones Red Clover
ModerateRed clover isoflavones come from red clover, so if you take them alongside Tamoxifen, the Tamoxifen may not work as well as it should. In plain terms, red clover isoflavones can weaken the effect of Tamoxifen when the two are used together.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
