Dayvigo for long term use?

I asked my psychiatrist about Dayvigo, since I have now tried and failed trazodone, mirtazapine, and ramelteon. She said that she it’s not safe for long term use and is much like the Z-drugs in that you can get pretty dependent on it. Now, a simple google search tells me it’s safe for long term use and does not carry much of a risk for dependency, but I was wondering if anyone here can confirm or deny?
