Overview
Januvia 100mg Tablet contains sitagliptin 100mg, a dipeptidyl peptidase-4 (DPP-4) inhibitor used together with diet and exercise to improve blood glucose control in adults with type 2 diabetes mellitus, either alone or in combination with other antidiabetic medicines such as metformin.
Sitagliptin works by blocking the DPP-4 enzyme, which normally breaks down incretin hormones (such as GLP-1) released after eating. By preserving these hormones for longer, sitagliptin increases insulin release from the pancreas and reduces glucagon release, in a glucose-dependent manner that lowers blood glucose mainly around meals.
How it Works
Sitagliptin inhibits DPP-4, the enzyme responsible for rapidly degrading incretin hormones GLP-1 and GIP. This prolongs the active levels of these hormones, which enhance glucose-dependent insulin secretion from pancreatic beta cells and suppress glucagon secretion from alpha cells, together improving blood glucose control with a relatively low risk of hypoglycemia when used alone.
Directions for Use
Take Januvia 100mg Tablet once daily, at about the same time each day, with or without food, swallowing the tablet whole with a glass of water. Continue taking this medicine regularly, even if you feel well, as ongoing treatment is needed for long-term blood glucose control.
Dosage
The usual dose of Januvia 100mg Tablet is once daily, taken with or without food, though your doctor may adjust the dose if you have reduced kidney function. Always take exactly as prescribed and continue any recommended diet and exercise measures alongside this medicine.

Drug / Food Interactions
- Sulfonylureas (e.g. glibenclamide, gliclazide): combining with sitagliptin increases the risk of hypoglycemia, and your doctor may reduce the sulfonylurea dose
- Insulin: combining with sitagliptin also increases hypoglycemia risk, and an insulin dose reduction may be needed
- Digoxin: sitagliptin can slightly increase digoxin levels, so monitoring is advised if used together

- Take at the same time each day alongside your prescribed diet and exercise plan
- Report severe abdominal pain to your doctor promptly, as it could indicate pancreatitis

Frequently Asked Questions
What is Januvia 100mg Tablet used for?
Januvia 100mg Tablet is used, alongside diet and exercise, to improve blood glucose control in adults with type 2 diabetes, either on its own or combined with other diabetes medicines such as metformin.
Does this medicine cause hypoglycemia (low blood sugar) on its own?
When used alone, sitagliptin has a relatively low risk of causing hypoglycemia because it works in a glucose-dependent manner. However, the risk increases if it is combined with a sulfonylurea or insulin, in which case your doctor may adjust those medicines’ doses.
Do I still need to follow a diet and exercise plan while taking this medicine?
Yes, sitagliptin is intended to be used together with diet and exercise, not as a replacement for them – lifestyle measures remain an important part of managing type 2 diabetes.
What symptoms should make me contact my doctor urgently?
Seek prompt medical attention for severe, persistent abdominal pain (which could suggest pancreatitis), or signs of a severe allergic reaction such as facial swelling, difficulty breathing, or a widespread blistering skin rash.
What should I do if I miss a dose of Januvia 100mg Tablet?
