Upsides
  • Precose (acarbose) helps control meal-time blood sugar levels without causing weight gain.

  • Safe to be used in people age 65 or older.
  • Has relatively few interactions with other medicines.
  • Insulin is the most effective blood sugar-lowering medicine. When used correctly, it'll lower blood sugar every time you use it and prevent the harmful effects of high sugar levels on your organs and blood vessels.

  • Dose can be easily adjusted to make a customized regimen that's tailored to your body.
