I can't argue with a Doctor about anti-biotics, but Medifast is a Medically approved "food" and "should" work as good as any food to dampen the effects of the meds on your tummy. Personally, I'd just schedule the meds with one of my regular Medifast meals, but that's me.
You could email one of our nurses at
judy@medifastdiet.com, for a professional opinion on the question.
Anti-biotics do have there place, I guess, but personally, I refuse to take them unless I'm dying of gang-green or something some day (knock on wood). I haven't taken them for 30 years.
After you're through with your meds, you might want to look for those little bugs that live in your stomach that you'll destroy with the anti-biotics. They're very important to digestion and your immune system. You should be able to find them in pill form at your health food store. (They're in Yogurt, but better not eat yogurt while on the plan)
I like to think my bods capable of fighting off disease and infections on it's own, thank you....
