No doubt you can take along with Milk but here are some instructions from side
The Table what you taking is combination of two drugs (Tab.Glimepiride
the drug Glimepiride will cause low sugars in your body so, make sure that you take enough breakfast at least bread or biscuit along with milk and again at 11 a.m you can have fruit or snack so that your sugar levels will not go down.
You can also request your treating doctor to modify the Drug combination, My suggestion is it will be more safe if we go for Glimepiride in the morning dose (single dose) Metformin along with 2 major meals.
When ever you sweat/feel weak; take some sugar containing juice
all the best
