See the DrugPatentWatch profile for Januvia
Januvia is a brand-name prescription medication used to treat type 2 diabetes [1]. It is available in several dosage strengths, including 40 mg [1]. The active ingredient in Januvia is sitagliptin [1].
What is Januvia 40 mg used for?
Januvia 40 mg is prescribed as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes [1]. It works by increasing levels of incretins, which are hormones that stimulate the release of insulin and decrease the release of glucagon [1].
How does Januvia work to lower blood sugar?
Januvia contains sitagliptin, which is a dipeptidyl peptidase-4 (DPP-4) inhibitor [1]. DPP-4 is an enzyme that breaks down incretin hormones, such as GLP-1 and GIP. By inhibiting DPP-4, sitagliptin prolongs the action of these incretins, leading to increased insulin secretion and reduced glucagon secretion, thereby lowering blood glucose levels [1].
What is the typical dosage of Januvia?
While Januvia is available in strengths like 40 mg, the most common recommended dose for type 2 diabetes is 100 mg once daily [1]. The 40 mg dosage might be used in specific clinical situations or as part of combination therapy. Healthcare providers determine the appropriate dosage based on individual patient needs and other medications being taken [1].
Are there other strengths of Januvia available?
Yes, Januvia is available in multiple strengths, including 25 mg, 50 mg, and 100 mg, in addition to 40 mg [1]. The choice of strength depends on the patient's condition and the prescriber's recommendation.
When does the patent for Januvia expire?
Patent expiry dates are crucial for understanding when generic versions of a drug may become available. Information on the patent status and expected expiry for Januvia and its active ingredient, sitagliptin, can be found through resources like DrugPatentWatch.com [2].
What are the potential side effects of Januvia?

More serious, but less common, side effects may include pancreatitis, severe joint pain, and allergic reactions [1]. Patients should discuss any concerns about side effects with their doctor.
Can Januvia be taken with other diabetes medications?
Januvia is often prescribed in combination with other diabetes medications, such as metformin or sulfonylureas, to achieve better blood sugar control [1]. Your doctor will decide if Januvia is appropriate for your individual treatment plan and what combination of medications is best.
