High Liver Enzymes

So, he's only been on the Voriconazole (antifungal medication) for about a week, but at his first weekly lab draw, they saw his liver enzymes were elevated. I am surprised it happened so quickly. So, they have lowered the dosage of Voriconazole he is taking, and have added Ursodiol to help his liver out. Within a few days of starting Voriconazole, he started complaining of blurry vision, especially when it is dark, or very bright out, but this seems to have subsided. The Prednisone (steroids) seem to be making him a bit moody, but nothing to extreme at this point. It seems to be giving him redness in the face, but luckily no other side effects.

The past few days, his cough seems to be coming back. His lungs sound pretty clear, so I'm hoping this is just temporary.
