I was at the hospital at 1:30 am because my son was running a very high fever. He felt very hot when I took him out of his bed. My thermometer wasn t working so I rushed him straight to the ER where they took it and it was 103.6- at 2:17 am they gave him Tylenol. At 3:17am they gave him motrin because I had only given him motrin at 6:20pm the night before (no Tylenol until they administered). They told me to alternate between Tylenol and Motrin every 4 hours so as not to O.D. I automatically issued that it was OK to give him one or the other every 4 hours since their purpose was pretty much the same (to bring down fever). So like an IDIOT, I have him another dose of motrin at 8am and then another at 12noon. (First was 5 hours after initial and then the 2nd was 4 hours after the previous). I didnt have tylenol to give him so i pretty much substituded the tylenol doses with motrin. I am so scared right now. I didnt realize what I had done until after the 2nd dose. So he had all of this motrin within a 9 hour period. The two doses I gave him were 1.875ml each and I m unsure what the hospital have him. Will my son be OK or should I take him to the doctor? We re the doses far enough apart to where it won t hurt him? If it helps, my son is 29.1 pounds and is 17 months old and 33.5 tall.
