Antibiotics do tend to be sugary/syrups, this is because they taste vile.Not sure if it helps, they still smell pretty vile. Anyway, If you want to see, look at the Patient Information Leaflet. There's a trend to cut out sugar in most liquid medication, to save kid's teeth as much as anything, but i'm guessing that antibiotics are pretty low priority since few people are on them for a long length of time (some people are, if Alex is ask your pharmacist to check it out). Copepod's right (as usual 🙂) it might be the infection that's causing the high and if so, that should improve.
