I've been concerned about this one for a while, as it is listed as one of the "talk to your doctor immediately" symptoms.
I've been on azathioprine for about 5 years now and my pee looks like that every time I take the medicine. I've always worried this is a sign that the meds are really stressful on my kidneys or maybe liver, but my docs have never seemed too concerned by it...
But it seems like it's fairly common and no one else here is too concerned by it so I guess it's ok?
