Hi Punisher, I posted this in your other thread but figured I'd share it here as well.
6-MP and Lialda can be taken together. There are warnings (most poorly worded or mistaken) out there on the internet about taking them together because they DO interact. However, what studies have found is that 6-TGN levels (a metabolite of 6-MP) are increased by Mesalamine (the active ingredient in Lialda). Now, this may be bad if your 6-TGN levels are already too high. But if your 6-TGN levels are too low, then the Lialda may actually make the 6-MP work right because you want your 6-TGN in a specific therapeutic range. Neat huh? Your doctor should be regularly monitoring your blood work to make sure nothing is going wrong and may also choose to do a specialized test that actually monitors that 6-TGN level. That way if yours in fact does go too high, he or she may choose to take you off the Lialda to see if that helps.
Kinda confusing, I know
Let me know if you need anything specific explained. You can also follow that 6-TGN link above to learn more about it. It also contains links to studies that verify what I am saying.
In addition, we have
a subforum dedicated to 6-MP located here so you can connect with others on it. You'll see others in that forum on "Imuran" and "Azathioprine". They're very similar to 6-MP in that they actually turn into 6-MP once the body starts to break them down. So they're your med buddies too
