Liver toxicity due to Azathioprine

Hello,
I have been diagnosed with IGA Vasculitis and was taking Azathioprine 100 mg until recently when my Liver enzymes AlT and AST elevated to 8 to 10 times beyond the normal ranges.
I was taken off the azathioprine but continue with the prednisone for another 56 days on a taper dosage.
I am wondering if anyone has experience this and how long it may have taken for your liver enzymes to return to normal and while off Azathioprine did your IGA labs get worse?
Also did/does anyone experience extreme dizziness/light headedness and tiredness while on azathioprine and prednisone?
Thanks for any input or thoughts!
