What is Januvia?

Januvia is an oral tablet prescribed to help manage type 2 diabetes. The active ingredient in Januvia is sitagliptin. Sitagliptin helps control blood sugar levels by increasing insulin production and decreasing the amount of sugar released by the liver.

The Food and Drug Administration (FDA) has approved Januvia as an add-on treatment to diet and exercise for adults with type 2 diabetes. Januvia is not approved for type 1 diabetes.

Unfortunately, brand name Januvia can be expensive in the U.S. due to patent laws. High costs can make it challenging for some patients to access this medication. One way to significantly reduce the price is to buy Januvia from an online Canadian pharmacy like My Drug Center. The same FDA-approved Januvia is available from reputable pharmacies at a fraction of the U.S. cost.

Your body normally regulates blood sugar levels by using certain hormones called incretins. Incretins instruct your body to produce more insulin and less sugar. However, an enzyme called dipeptidyl peptidase-4 (DPP-4) breaks down incretins, limiting their effects. As a result, blood sugar levels remain higher than normal.

Januvia (sitagliptin) is a medication known as a DPP-4 inhibitor. It works by blocking the DPP-4 enzyme from breaking down incretins. By blocking DPP-4, Januvia allows incretins to stay active in your body for longer. With more active incretins, your body receives signals to increase insulin production and decrease sugar production. This helps lower your blood sugar levels to a healthy range.

Januvia Dosages

Januvia comes as oral tablets that are available in three dosages: 25 mg, 50 mg, and 100 mg. The dosage your doctor prescribes will depend on their evaluation of your medical history and symptoms.

Januvia is meant to be taken once daily, with or without food. Your doctor may occasionally do blood tests to monitor your kidney function while you are on Januvia. Based on these tests, they may adjust your Januvia dosage as needed.

It's important to pair taking Januvia with a healthy lifestyle. Maintaining a nutritious diet and getting regular exercise can help you experience the full benefits.

If you miss a dose of Januvia, take it as soon as you remember. But if it's close to the time for your next dose, skip the missed one and stick to your regular schedule. Do not take two doses to make up for a missed dose.

Januvia Side Effects

Januvia can cause side effects in some people. If any side effects persist or become bothersome, contact your doctor right away.

Common side effects include:

  • Upper respiratory tract infection
  • Stuffy nose
  • Runny nose
  • Sore throat
  • Headache


What is Januvia used for?

How much does Januvia cost?

Januvia is an expensive medication in the United States, even for those with insurance plans. The retail price for a 30-day supply of Januvia can be over $600. This presents a significant financial burden for many patients who rely on Januvia to manage their diabetes.

Fortunately, there are ways to save money on important medications like Januvia. Ordering from a reputable online Canadian pharmacy can help reduce your costs by up to 90% compared to U.S. retail prices. Reputable pharmacies like My Drug Center source prescription drugs from Canada, where government regulations cap the prices of medications. They are then able to pass on significant savings to their customers.
