Zofran IV

Hi all,

I'm not a nurse but a concerned patient with a quick question about Zofran. I'm a 20 year old female. I was in the ER for about 12 hours today after a scare with a pulmonary embolism (I don't have one, yay!) but I also had diarrhea once before I went to the ER around 11:30 PM Wednesday. I threw up during my blood draw at about 1:00 AM Thursday. I was awake for most of the night and nausea set in about 4 AM or 5 AM Thursday morning. I'd had an IV for fluids somewhere in there, and sometime between 8 and 10 (kind of a mixed up mess in my head) the nurse gave me an IV injection of Zofran. I'm pretty sure she flushed it twice and it burnt a little bit going in but not anything awful. I made the mistake of reading about Zofran online and all of the issues it can cause with prolonged QT intervals, which I have a weird phobia of having (my most recent EKG the interval was 362 ms). Anyways, I don't know how much the IV injection was because I really wasn't paying that much attention. Anywhere between 7 and 9 hours has passed since the injection. I was moved to a room where they had a heart monitor on for about half an hour (just to free up bed space in the ER) and maybe 30 minutes after that they released me.

I don't really know anything about Zofran. I have not been having any adverse symptoms (my heart rate gets going really fast when I get out of bed but I'm still feeling kinda cruddy (think it may have been the flu?) and have occasional bouts of very little diarrhea. However I haven't eaten anything or slept much, just trying to stay hydrated. Are prolonged QT intervals something I should worry about after just this one and only IV dose? I didn't experience any adverse reactions in the hospital either, I actually fell asleep for a few hours. I know that no one would've given it to me if they were worried about it, but I am such a worrier about that kind of stuff. I also had another EKG done probably 4 hours before the Zofran dose. Thanks so much!
