Can I Skip Metformin For One Day And When Should I Take It?

I cannot remember if I took my metformin 850. it is now 3 hours after lunch and my reading is 112.can I wait and take my pill tomorrow or is this normal. I can monitor my blood and if it goes too high I can take my pill, but what reading does it have to read before I take my pill?

Since your sugar is 112 and you do not remember if you have taken your metformin 850 mg, and 3 hours have past, it is evident that you have taken your metformin.This is because your sugar level is normal now,and that you already had your lunch 3 hours before, so now the action of metformin is almost completed, and the Carbohydrate.... sugar in your system(glucose) is normal.You can wait till tomorrow,as this is normal.Always remember.... Metformin(850) is safe drug in diabetes.. provided the blood sugar level is maintained above 150.You can safely repeat metformin(850) if level of sugar is above 150.Also note
An exercise like walking for 20 min ( in case you do not remember whether medicine was taken , will help a lot to reduce the blood sugar level, and also not cause a low blood sugar level.
Ideally if you wish to control your diabetes and reduce the sugar levels, It is recommended to do exercise for 20 min(simple walking) after half an hour of taking metformin.... but after lunch or dinner and within 4 hours of taking metformin.

Hope you follow my advice and keep me posted on the effect of exercise after taking metformin(within 4 hours of consuming metformin)
