Well 6 weeks post diagnose my 7 year old developed an ear and throat infection. She was promptly prescribed sugar free amoxicillin. The first pharmacy I went to tried to give me full sugar medicine I was quite relieved that I double checked when I got the bottle ! the 2nd pharmacy showed me the bottle (paranoid mummy) and it deffinatly said sugar free on it so I was happier, as the week has gone on her sugars have gradually raised to above acceptable levels and at first I thought it was the infection however her dad forgot to give her a team time dose last night, and her sugars returned to normal, and then immediately following the dose today her sugars have shot up. I have made the decision to stop them, she is 7 days into treatment, is better and only a couple of doses left so my question is can sugar free cause a raise in sugars-is there some sort of sweetener substitute that can affect her sugars ?
