I don't know what the numbers mean, but it is possible that the herbs in the Tetra Cleanse are releasing a number of toxins that may result in elevated levels until they are eliminated from his body. The probiotics may also be producing some candida die-off which do this, as well.
I can't tell you what to do...only what I would do, and that is keep cleansing. I'd also keep him off the medication if he's feeling better without it.
