Hi Tabby
pumping the stomach only helps if it is done almost immediately when the stuff is ingested. once the stuff is absorbed pumping the stomach does no good. the throwing up is not, in the case of carbamazepine, the result of stomach irritation. it is an effect of drug intoxication.... the stuff was already in his system when he got there.
bizarre no fluid replacement... i was hooked up to one of those big liquid bags for 24 hours, they said they had to put minimum 3 of those things through me... and then redraw my levels!

AND during that 24 hours, they were collecting/measuring my "liquid output" as well! plus i was on all kindsa monitors, O2 monitor, heart...
maybe he is less acute than i was ... i'm sure they drew his levels.... you probably don't need to worry. the XR will take time to flush out though, that's the only thing, and they can't really speed it up. i am sure they are making sure he drinks water. i passed out after a while, so probably they had to do iv fluids on me as i couldn't drink.
see, the best we could figure, in my case, is that i took a defective 400XR and it delivered the full amount into my blood immediately.
i hope you have a good visit with your hubby. you are a trooper.
