What is Januvia?

Januvia (sitagliptin) is a prescription medication used to improve blood sugar control in adults with type 2 diabetes. It belongs to a class of drugs known as DPP-4 inhibitors and is often used when other diabetes medications, like metformin, have not provided adequate control of blood sugar levels.

Januvia Drug Class and Categories

Drug Class: DPP-4 Inhibitor (Dipeptidyl Peptidase-4 Inhibitor)

Categories:

• Oral Antidiabetic Agents
• Blood Sugar Control Medications

Active Ingredient in Januvia

The active ingredient in Januvia is sitagliptin. It works by regulating insulin levels in the body, particularly after meals, which helps to lower blood sugar levels.

Popular and Other Names

• Brand Names: Januvia
• Generic Name: Sitagliptin
• Other Names: Sitagliptin Phosphate

Mode of Action

Januvia works by inhibiting the enzyme DPP-4, which breaks down incretin hormones in the body. Incretins are hormones released by the intestines in response to food intake and play a significant role in regulating insulin and blood sugar levels. By preventing the breakdown of these hormones, Januvia increases the levels of insulin released by the pancreas and decreases the amount of sugar produced by the liver.

How to Use Januvia

Januvia is taken orally, with or without food. It is usually taken once daily. For best results, it should be taken at the same time each day. Januvia is often prescribed in combination with other antidiabetic medications.

Recommended Dosage

The recommended dosage for Januvia is 100 mg once daily. The dosage may be adjusted based on individual response and the presence of any kidney impairment. Always follow your healthcare provider's instructions regarding the dosage.

Directions for Use

• Take Januvia exactly as prescribed by your healthcare provider.
• Do not crush or chew the tablet; swallow it whole with water.
• Take it at the same time each day to maintain an even level in your bloodstream.
• If you miss a dose, take it as soon as you remember. If it's close to the time of your next dose, skip the missed dose and continue with your regular schedule. Do not double the dose.

Cautions
