What is Januvia (sitagliptin)?

What is Januvia (sitagliptin) used for?

  • Type 2 diabetes in adults

How Januvia (sitagliptin) works

Typically, your body controls blood sugar by releasing certain hormones. These hormones tell your body to make more insulin and to produce less sugar. But a protein called dipeptidyl peptidase-4 (DPP-4) breaks down these hormones. As a result, you have higher levels of sugar in your blood.

Januvia (sitagliptin) is a DPP-4 inhibitor, which means that it blocks the action of DPP-4. In doing so, Januvia (sitagliptin) allows insulin to stick around longer in your body and tells your body to make less sugar. These actions lower your blood sugar levels.

Pharmacist tips for Januvia (sitagliptin)

pharmacist

  • Take Januvia (sitagliptin) every day with or without food.

    • It's best to avoid alcohol when possible during treatment with Januvia (sitagliptin). Drinking alcohol with this medication can cause dangerously low blood sugar and raise your risk of an inflamed pancreas. If you drink alcohol regularly and it's difficult for you to cut it out completely, ask your provider what's a safer amount to drink.

      • Tell your provider right away if you experience severe stomach pain that doesn't go away. This can be a symptom of an inflamed pancreas (pancreatitis).

        • If you're taking Januvia (sitagliptin) with other diabetes medications that can lower your blood sugar levels, like insulin or glipizide, you might be at risk of having dangerously low blood sugar. Make sure to check your blood sugar if you feel shaky, confused, or have a fast heartbeat. Drink four ounces of fruit juice (about the amount in a typical juice box) or take four glucose tablets if your sugar levels are low (less than 70 mg/dL).

          • Tell your provider if you experience any changes in weight, trouble breathing, unusual tiredness, or swelling in the feet, ankles, or legs while taking Januvia (sitagliptin). Though rare, it's possible for this medication to cause or worsen heart failure. Let your provider know if you have a history of heart problems before starting Januvia (sitagliptin).

            • It's important to eat healthy and exercise regularly to keep your blood sugar under control. Make sure to work with your provider on a diet and exercise plan while taking Januvia (sitagliptin).

Your provider might order blood work done before you start treatment and while you take Januvia (sitagliptin) to check your kidney health, especially if you already have kidney problems. If you develop any kidney problems, you might need to stop taking this medication. Talk with your provider if you're urinating less than usual while taking Januvia (sitagliptin).

                  risk-warning

                  Serious allergic reactions

                    Rarely, Januvia (sitagliptin) can cause serious allergic reactions, such as rash, peeling or blistering skin, swelling, trouble breathing, and dizziness. This is more likely to happen within the first three months you start this medication. Let your provider know if you've had an allergic reaction to other DPP-4 inhibitors or "gliptins", such as Tradjenta (linagliptin) or alogliptin (Nesina). Though unclear, it's possible that taking Januvia (sitagliptin) might cause you to have another allergic reaction. If you experience an allergic reaction to Januvia (sitagliptin), stop the medication and get medical care right away.
