Prandin (repaglinide)

Prescription only

Precose (acarbose)

Prescription only
Lowers blood sugar.

Prandin (repaglinide) works quickly to lower blood sugar, especially during mealtimes. However, it can cause hypoglycemia (low blood sugar) if you are not consistent with your diet and exercise schedule.

Lowers blood sugar.

Precose (acarbose) helps lower your post-mealtime blood sugar levels, but it must be taken at the beginning of each main meal in order for it to be most effective.

Upsides
  • Quickly and effectively lowers blood sugar during meal times.
  • Less likely to cause hypoglycemia (low blood sugar) than Starlix (nateglinide).
  • Good first-choice if you cannot tolerate metformin or add-on therapy if your blood sugars are not controlled on metformin alone.
  • Precose (acarbose) helps control meal-time blood sugar levels without causing weight gain.
  • When used alone it doesn't normally cause blood sugar levels to be too low unlike other anti-diabetes medicines.
  • Safe to be used in people age 65 or older.
  • Has relatively few interactions with other medicines.
Downsides
  • May cause some weight gain.
  • May cause hypoglycemia (low blood sugar).
  • Can frequently interfere with how other medicines work.
  • Not a good choice if you have poor kidney function, liver problems, or younger than 18 years old.
  • Not a first choice medicine because it isn't as effective at lowering blood sugar compared to other treatment options.
  • Associated with bothersome side effects like excessive gas and diarrhea.
  • Relatively more expensive than other diabetes medicines.
  • Has to be taken three times a day with each meal.
  • Might cause episodes of low blood sugar when taken together with insulin or medicines that stimulate insulin release.
