Acarbose Hypoglycemia: Why You Must Use Glucose, Not Sucrose
Acarbose blocks sucrose breakdown, so it won't raise low blood sugar. Treat acarbose-related hypoglycemia with glucose tablets or milk instead.

Januvia vs Actos: Key Differences in Effect and Risk
Januvia is weight-neutral with low hypoglycemia risk but modest HbA1c drop; Actos lowers glucose more but can cause weight gain and fluid retention.
