I won't mix them. They are antagonistic. I still don't understand what you want to combat with those systemic drugs. Where is the problem ?? Systemic drugs have low impact on gastrointestinal infections.
Jorge.

Was your sensitivity test on stool or blood? (I guess I'm asking, do you think your infection is only in your intestinal tract, or do you think it is also in your blood)

Because it seems unclear if itraconazole lasts all the way down to the lower gut... if you are mostly concerned with your gut and not worried about anything in your blood, the itraconazole wouldn't target the lower part of your gut if it gets absorbed into the bloodstream fairly high up in the gut.

If anyone decides itra does not last into the lower gut (and again, I'm not sure), I wonder if one way around this is to do this: mix the antifungal into a premixed drink of psyllium and water, after the psyllium and water has sat for 10 minutes and thickened. The people at Whole Approach Forum do this with some natural antifungals, saying the gel of the psyllium and water delivers the antifungal lower down, slowly releasing it along the gut wall as the gel travels down. I wonder if it would work with this Rx.

No clue on the interaction of itra with berberine though, sorry.
