Elvated ALT levels

Hi all I have been taking Kalydeco for almost 5 months now. My liver test have been going downhill since. From normal range to an ALT level of over 250. Any words of wisdom? I have not spoken to the doc yet, but I am soooo worried. I don't want to stop Kalydeco - it is such a life changer.
