Uses
What is Januvia used for?
Januvia (sitagliptin) is used with diet and exercise to help lower blood sugar levels in people with type 2 diabetes.
Januvia may also be used for other conditions as determined by your healthcare provider.
How does Januvia work?
Januvia works to help keep your blood sugar levels from getting too high. Januvia blocks an enzyme called DPP-4. Blocking DPP-4 helps increase the levels of natural hormones in your body called incretins. Incretins help lower blood sugar by increasing insulin levels, especially after meals. They also decrease the amount of glucose (sugar) that is made by the liver.
Januvia is available in the following dosage forms that are taken by mouth.
- 25 mg oral tablets
- 50 mg oral tablets
- 100 mg oral tablets

Januvia should be stored at room temperature, between 68 F to 77 F (20 C to 25 C). It can be exposed to temperatures between 59 F to 86 F (15 C to 30 C), for shorter periods of time, such as when transporting it. Store in a cool, dry place, in a tightly closed container.
