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
  • DRUG-NAME is an oral blood sugar lowering medicine. It's a good option if you don't like injections.
  • Does not cause weight gain.
  • May be a good option for those with bad liver function.
  • Does not cause hypoglycemia (low blood sugar) when taken by itself.
  • 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
  • Typically not first-choice treatment for diabetes.
  • Only lowers A1C (average blood sugar over time) by ~0.5%.
  • Risk for heart failure has not been seen in other medicines that work just like it.
  • May be more expensive than other anti-diabetic medicines.
  • 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.
