Hi Tala
I did read that it can be dangerous to take grapefruit seed extract with Doxy, because it increases the concentration of Doxy in your blood. Some people do it- but only after their Dr has okay'd it.
I have taken it with Biaxin, Bactrim, Rifampin and Ceftin (not all at once! :) ), and it's been fine. But I would recommend checking either with your doctor or a nauturopathic doctor beforehand, just in case.
