Hi Doctor, My Son Has Accidently Chewed My Glycazide Tab

Hi Doctor, My son has accidently chewed my glycazide tab . When i found him the tablet was still in his mouth full. Just little juice in his mouth. I took it out gave 3 spoons of sugar. It has been 6 hrs since then He had his dinner and milk..he seems fine no symptoms. Its midnight here and he is fast asleep. I just worried want to know if he will be ok.

Thanks
