Does milk thistle cause drug interactions?

Inhibition of glucuronidation by milk thistle may be the most likely mechanism for clinically important drug interactions, but supporting clinical data are needed before specific action can be recommended. Drs. Horn and Hansten are both professors of pharmacy at the University of Washington School of Pharmacy.

Does milk thistle have any effect on P-gp?

Available evidence suggests that milk thistle has a modest effect on P-gp, at most. More study is needed to confirm this. Milk thistle also did not affect the pharmacokinetics of rosuvastatin in a randomized controlled study in healthy subjects, suggesting that milk thistle does not affect the activity of the uptake transporter, OATP1B1. 5
