About Januvia

Januvia is a prescription medicine used along with diet and exercise to lower blood sugar in patients with type 2 diabetes mellitus (type 2 diabetes). Januvia may be taken alone or along with certain other medicines to control blood sugar.

  • Januvia lowers blood sugar when blood sugar is high, especially after a meal.
  • Januvia also lowers blood sugar between meals.
  • Januvia helps to improve the levels of insulin produced by your own body after a meal.
  • Januvia decreases the amount of sugar made by the body.
  • Januvia is unlikely to cause your blood sugar to be lowered to a dangerous level (hypoglycemia) because it does not work when your blood sugar is low.

Januvia has not been studied in children under 18 years of age.

Januvia has not been studied with medicines known to cause low blood sugar, such as sulfonylureas or insulin. Ask your healthcare professional if you are taking a sulfonylurea or other medicine that can cause low blood sugar.
