FAQs About STEGLUJAN™ (ertugliflozin and sitagliptin)

Get the facts from our FAQs.

STEGLUJAN is for adults with type 2 diabetes, in addition to diet and exercise. Not for treating type 1 diabetes or diabetic ketoacidosis (increased ketones in the blood or urine). If you have had pancreatitis (inflammation of the pancreas) in the past, it is not known if you have a higher chance of getting it while you take STEGLUJAN.

STEGLUJAN works with the pancreas to increase insulin production, the liver to reduce sugar production, and the kidneys to remove some sugar when you pee.

STEGLUJAN is a once-daily pill you take in the morning, with or without food. Not an injection. You can make STEGLUJAN part of your morning routine.

Although it's not for weight loss, STEGLUJAN may help you lose some weight.*

STEGLUJAN may cause serious side effects, including:

  • Inflammation of the pancreas (pancreatitis) which may be severe and lead to death. Certain medical problems make you more likely to get pancreatitis.

Before you start taking STEGLUJAN, tell your doctor if you have ever had:

  • pancreatitis
  • a history of alcoholism
  • kidney problems
  • stones in your gallbladder (gallstones)
  • high blood triglyceride levels

Stop taking STEGLUJAN and call your doctor right away if you have pain in your stomach area (abdomen) that is severe and will not go away. The pain may be felt going from your abdomen through to your back. The pain may happen with or without vomiting. These may be symptoms of pancreatitis.

  • Dehydration. STEGLUJAN can cause some people to become dehydrated (the loss of body water and salt). Dehydration may cause you to feel dizzy, faint, lightheaded, or weak, especially when you stand up (orthostatic hypotension). You may be at risk of dehydration if you:
    • have low blood pressure
    • take medicines to lower your blood pressure, including water pills (diuretics)
    • have kidney problems
    • are on a low sodium (salt) diet
    • are 65 years of age or older

    Talk to your doctor about what you can do to prevent dehydration including how much fluid you should drink on a daily basis.

  • Vaginal yeast infection. Women who take STEGLUJAN may get vaginal yeast infections. Symptoms of a vaginal yeast infection include:
    • vaginal odor
    • white or yellowish vaginal discharge (discharge may be lumpy or look like cottage cheese)
    • vaginal itching
  • Yeast infection of the penis (balanitis or balanoposthitis). Men who take STEGLUJAN may get a yeast infection of the skin around the penis. Certain men who are not circumcised may have swelling of the penis that makes it difficult to pull back the skin around the tip of your penis. Other symptoms of yeast infection of the penis include:
    • redness, itching, or swelling of the penis
    • rash of the penis
    • foul smelling discharge from the penis
    • pain in the skin around your penis

Talk to your doctor about what to do if you get symptoms of a yeast infection of the vagina or penis. Your doctor may suggest you use an over-the-counter antifungal medicine. Talk to your doctor right away if you use an over-the-counter antifungal medicine and your symptoms do not go away.

  • Heart failure. Heart failure means your heart does not pump blood well enough. Before you start taking STEGLUJAN, tell your doctor if you have ever had heart failure or have problems with your kidneys. Contact your doctor right away if you have any of the following symptoms:
    • increasing shortness of breath or trouble breathing, especially when you lie down
    • swelling or fluid retention, especially in the feet, ankles or legs
    • an unusually fast increase in weight
    • unusual tiredness

These may be symptoms of heart failure.

STEGLUJAN may have other side effects. See Possible Risks & Side Effects to learn more.

Even if you’re working hard to eat right and exercise, your A1C levels may increase over time. This is not unusual and can happen no matter how hard you work. You're not alone. Many people with type 2 diabetes often need to add or change medications to help get A1C levels under control. STEGLUJAN builds on the work you’re already doing. It can help you make progress lowering your A1C.

  • Ketoacidosis (increased ketones in the blood or urine) has happened in people with type 1 and type 2 diabetes during treatment and also in people with diabetes who were sick or who had surgery during treatment with STEGLUJAN. Ketoacidosis is a serious condition, which may require hospitalization and may lead to death. Symptoms may include nausea, tiredness, vomiting, trouble breathing, and abdominal (stomach area) pain. If you get any of these symptoms, stop taking STEGLUJAN and call your doctor. If possible, check for ketones in your urine or blood, even if your blood sugar is less than 250 mg/dL.

Follow your doctor’s instructions for treating low blood sugar.
  • Necrotizing fasciitis, a rare but serious bacterial infection of the tissue under the skin in the area between and around the anus and genitals (perineum), has happened in women and men who take medicines that lower blood sugar in the same way as STEGLUJAN, which may lead to hospitalization, multiple surgeries, and death. Seek immediate medical attention if you have fever or feel very weak, tired, or uncomfortable and you develop: pain or tenderness, swelling, or redness of skin in the perineum.
  • Increased fats in your blood (bad cholesterol or LDL).
  • Serious allergic reactions. If you have any symptoms of a serious allergic reaction, stop taking STEGLUJAN and call your doctor right away.
