i can't think of any reason off the top of my head how tea drinking could adversely interact with medication. i'd wager many brits take their meds with tea so if there were an interaction we'd probably know about it. that is only my opinion however and should only be taken at face value. your best bet is to consult a pharmacist. he or she is highly qualified to answer any of your questions about medications supplements interactions and so on. hope this helps!
can lizinopril hctz interact with oolong tea?
