We used it a couple of weeks ago for DS (who is 2) after the doctor told us to get some ... he had horrible eczema and hadn't slept for 3 nights from the itching and discomfort. He did warn us that while it might work on some kids to make them tired, it doesn't work on all kids. For DS, the antihistamine didn't work to reduce his ezcema and he was awake just as much on it as off it. We were told to use it through the day, but we gave him one dose at night and he acted drunk (he was really clumsy - walking into walls, falling over etc) so we decided against giving it to him during the day and didn't go back to it after one dose.

I had phenergan once when I was 13 while I had the chicken pox and it knocked me out cold for 16 hours. It seems like a really strong drug and one that I would avoid if possible. I haven't been that impressed by how it worked for me or for DS.
