Hi Dana (again),
No, Halcion is in pill form. I've done a bit of reading on it. It's normally prescribed for sleeping problems. I guess it's a sleeping pill they used to use before Ambien (which isn't as strong as Halcion).
I don't quite understand how a sleeping pill would be good for a dental procedure (seems like my head will be nodding and perhaps snoring

but doing a search on this board, it looks like it's quite common for sedation during dental surgery.
