elevated alk phos, ALT and AST

Help....

I am scheduled to have a hip replacement in a little over a week and had pre-op bloodwork done. My alk phos was 218, ALT 476 and AST 186. I have been taking a lot of Advil with Arthrotec twice a day and vicodin 5/500 two to three times per day due to the pain. I am also on Wellbutrin 150 mg per day and Cymbalta 60 mg per day. Could these elevations be due to my medications. None of my other results are abnormal and I had normal blood work done in December before being on all of these anti-inflammatories.

I am so worried that my surgery will be cancelled because of this. I really need to get this done so that I can resume my life.

any advice??
