Hormones and Birth Control with vitamins, minerals and herbal supplements
Supplements are widely used and rarely disclosed to the prescriber, which makes them a common source of unrecognised interactions with Hormones and Birth Control (Hormones and Birth Control). Many supplements are inert or harmless, but a small number — particularly herbal extracts and high-dose vitamins — can affect how Clomiphene, Conjugated Estrogens, Drospirenone, Estradiol, Estriol, Levonorgestrel, Levothyroxine, Progesterone, Raloxifene, Testosterone, Tibolone works at 1%, 1.62%, 0.3mg, 0.625mg, 1.25mg.
High-priority supplement interactions
St John's Wort is the herbal supplement most often flagged for interactions because it strongly induces CYP3A4 and reduces plasma levels of many medications including several Hormones and Birth Control agents. Grapefruit-extract supplements work in the opposite direction. High-dose vitamin K affects anticoagulants. Calcium and iron can chelate certain antibiotics.
