Yes, there still are Fentanyl-laced lollipops, or "suckers", if you prefer.
The trade name is Actiq, the doses range from 200-1000 mcg/sucker (if I recall correctly).
I have seen them most often used in the setting of chronic/cancer pain management. Perhaps other posters have more experience using them in Peds, if at all.
Oh, and the taste of the suckers....dreamy!
