Sorry. I have no experience in that department. You could ask your doctor if there would be any reason for caution. Some drugs wreak havoc on the body and can create constipation issues or exacerbate existing conditions.

Are you concerned about interaction between the herbs in the product and your medication? Also curious about what you want from the cleanse. If it's a need for fiber and regularity, perhaps you could try the fiber and tea first.  Or you may want to try a cleanse regimen that isn't as long as Colonix (although I think it's great!) One benefit of cleansing is that it encourages people to drink more water and that is helpful in general for the whole body.
