What should I avoid while taking Precose?

While you're taking the diabetes drug Precose (acarbose), you should avoid drinking alcohol in excess, because alcohol may cause a decline in blood sugar. Ask your doctor about the safe use of alcohol while on this drug. You should also avoid unhealthy meals and being inactive. If you don't follow your doctor's dietary instructions while taking Precose, you may experience more abdominal pain, diarrhea and gas.
