Been taking azathioprine 50mg taken twice daily for over 3 years now, and was just diagnosed via a colonoscopy, pockets in the colon walls, did biopsy and cancer was negative. No family history of this, and I believe azathioprine was the corporate. Just today my liver doctor reduced it to 25mg once daily. I am thinking azathioprine cannot be taken long term especially in high mg dosis.
Thanks a lot, very comprehensive & informative explanation, which is helpful to clear concepts & to remember it lifelong appreciated your hard work & sincere approach
