Green Tea and Blood Pressure Drug Don't Mix

b_250_0_16777215_00_images_obgrabber_2014-01_34f23f8246.jpgbit245/Thinkstock (NEW YORK) -- Health experts have touted the medicinal benefits of green tea for years but there’s a new report that might make some people reluctant to start enjoying the beverage. A team of international researchers from Japan, Germany and Italy say that green tea has been shown to interact with the prescription drug nadolol, which is taken to control high blood pressure.

The researchers discovered after studying 10 volunteers over two weeks who took both the drug and drank either green tea or water that the tea reduces the effectiveness of nadolol, which has the brand name Corgard. Therefore, they recommended anyone prescribed nadolol, which is less frequently used in the U.S. than other beta blockers, to avoid drinking green tea or at least check with their physicians before doing so.

Beta blockers help to lower blood pressure by slowing the heart rate and easing the heart’s workload.
