Metformin and Acarbose are paired when Metformin is taken during or after a meal and Acarbose is taken with the first meal, it is recommended to take the medication under the supervision of a doctor. Metformin and Acarbose are both hypoglycemic drugs. Metformin controls fasting blood sugar by reducing glucose output from the liver, while Acarbose reduces glucose absorption by controlling the body’s appetite, which in turn lowers postprandial blood sugar. The combination of the two can play a very good role in controlling pre-meal and post-meal blood sugar. However, there are also bad aspects of the combination of the two, metformin and acarbose have certain gastrointestinal reactions, such as nausea and vomiting, abdominal discomfort, so the combined application may increase gastrointestinal discomfort. The choice of hypoglycemic drugs is very important, you need to go to a regular hospital to follow the doctor’s instructions.
