Januvia® (Sitagliptin) Tablets for Type 2 Diabetes
Januvia® (sitagliptin) is a once-daily oral medicine used to improve glycaemic control in adults with type 2 diabetes mellitus. It enhances the body’s natural incretin system to help regulate blood glucose levels and is commonly prescribed alongside diet and exercise.
Purchasing Januvia® through LifePath Meds may provide a cost-effective option while maintaining access to genuine, high-quality medication.
What Is Januvia®?
Januvia® contains sitagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor. It works by increasing levels of incretin hormones, which stimulate insulin release in response to meals and reduce hepatic glucose production.
According to the National Institute for Health and Care Excellence (NICE), DPP-4 inhibitors may be used as monotherapy when metformin is unsuitable or in combination with other glucose-lowering therapies. In the UK, regulatory oversight is provided by the Medicines and Healthcare products Regulatory Agency (MHRA).
Indications
- Improvement of blood glucose control in adults with type 2 diabetes.
- Use as monotherapy or in combination with metformin, insulin, or sulfonylureas when additional glycaemic control is required.
Dosage and Administration
Route: Oral administration.
The usual recommended dose is 100 mg once daily. Dosage adjustments may be necessary in patients with impaired renal function.
Tablets may be taken with or without food and should be swallowed whole with water. To maintain consistent blood sugar control, take the medicine at approximately the same time each day.
If a dose is missed, it should be taken as soon as remembered on the same day. Do not take two doses within one day.

How Januvia® Works
Sitagliptin inhibits the DPP-4 enzyme, prolonging the activity of incretin hormones such as GLP-1 and GIP. These hormones increase insulin secretion when blood glucose levels are elevated and suppress glucagon release, helping to reduce postprandial and fasting glucose concentrations.
Unlike some other diabetes treatments, Januvia® does not usually cause weight gain and carries a low risk of hypoglycaemia when used alone.
Possible Side Effects
Common
- Nasopharyngitis (cold-like symptoms)
- Headache
- Upper respiratory tract infections
Serious but Rare
- Pancreatitis: Severe abdominal pain radiating to the back, nausea, or vomiting.

- Severe allergic reactions: Rash, swelling, difficulty breathing, or dizziness.
Seek immediate medical attention if serious symptoms develop.
Drug Interactions
