I've read that Glumetza can interact with magnesium and ginseng. I've been taking magnesium and ginseng at my naturopath's direction, however I am starting Glumetza soon (as per my endocrinologist) and don't want to have a reaction. Does anybody know how long magnesium and ginseng stay in your system? Should I stop taking them for a period of time before starting the glumetza?
