I drank lucozade on a regular basis through out my first and second pg. I also thought it would be safe as it is used for the glucose test which i had for both pg's. At the end of my second pg, I was admitted to hospital as baby's heart rate was through the roof. After a general Chat with a midwife I was scorned for drinking lucozade and blamed for babies high heart rate. A week and half later I was admitted again for the babies heart rate yet again being 210+ bpm, this time having not touched another drop of lucozade. So I'm undecided whether it was harmful or not. They say lucozade sport (isotonic drinks) are ok. Not lucozade. But having had two different occasions with and without Lucozade I can't say for sure what is best.
