Do you want to briefly talk about drug interactions?
I saw a Canadian Medical Association journal article that estimated that only 10% of adverse reactions are reported. The frequency of drug interactions, and Dr. Ellis referred to this early on in his questions.... I know there are quite a few drug interactions with natural health products. For example, they can affect the INR of Coumadin. It's less well known on newer anticoagulants like dabigatran. Some natural health products, like St. John's wort, can affect the plasma concentration of cyclosporine with organ transplants or antiretroviral levels.
Can you talk a bit about drug interactions between natural health products and other medications?
