3.4/ 5 average rating with 79 reviewsforJanumet
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.

Upsides
  • This 2-in-1 combination can lower the number of pills you have to take daily.
  • Lowers A1c (average blood sugar over time) up to 2.5%.
  • Available in extended and immediate release forms to allow better control of your blood sugar.
  • Doesn't increase your appetite unlike other anti-diabetic medicines.
  • Does not cause hypoglycemia or very low blood sugar.
  • 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.
Downsides
  • Available as brand name only and may be expensive.
  • Metformin component usually causes upset stomach.
  • Sitagliptin component may increase your risk for throat infections and inflammation of pancreas.
  • Not appropriate for those with poor kidney function.
  • 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.
