Steglujan (ertugliflozin / sitagliptin) is a combination medication for adults with Type 2 diabetes. The tablet has two diabetes medications that work in different ways to lower blood sugar. It contains ertugliflozin (an SGLT2 inhibitor) and sitagliptin (a DPP-4 inhibitor). You only need to take Steglujan (ertugliflozin / sitagliptin) once a day. It works best when you also follow a balanced meal and exercise plan for diabetes. But this medication can cause side effects like yeast infections. It also has risks like pancreatitis and severe joint pain.
Steglujan (ertugliflozin / sitagliptin) is a combination of two diabetes medications. They work together to lower blood sugar levels.
Ertugliflozin is a sodium glucose co-transporter 2 inhibitor, or SGLT2 inhibitor for short. It blocks the SGLT2 protein in the kidneys. This prevents sugar from absorbing back into your body through the kidneys. It makes the sugar go into your urine. This helps get rid of extra sugar in your blood and lower your blood sugar levels.
Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor. It's also known as a "gliptin." It blocks a protein in the body called DPP-4 from working. This helps insulin stick around in your body longer. It also stops your body from making glucagon, a hormone that raises blood sugar. Together, this helps control your blood sugar levels.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.

It can take a few weeks or months of taking Steglujan (ertugliflozin / sitagliptin) before you see changes to your A1C. Your A1C measures your average blood sugar over time. If you've been taking the medication for a few months and your A1C hasn't gotten better, talk to your diabetes care team. They can help make changes to your treatment plan, if needed.

If you have trouble swallowing the tablet whole, talk to your prescriber. They can help find a different medication that's easier for you to take.
Some people who take Steglujan (ertugliflozin / sitagliptin) might lose some weight. In studies, people lost an average of about 5 to 6 lbs after 6 months of treatment. This weight loss stayed pretty steady for a whole year of treatment. Keep in mind that people in these studies were also taking metformin. It's best to work with your diabetes care team to come up with a meal and exercise plan that fits you. Following a balanced, nutritious diet and staying active with the medication also help lower your blood sugar and keep you healthy. Talk to your care team about how to manage your weight appropriately.

Steglujan (ertugliflozin / sitagliptin) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Some people who take SGLT2 inhibitors, like the ertugliflozin in Steglujan, have had ketoacidosis. This happens when your body makes too many ketones for energy. When there are too many ketones, your blood gets too acidic. This can be very dangerous. Your risk can be higher if you're sick, not eating much, drinking a lot of alcohol, or just had surgery.
Stop taking Steglujan (ertugliflozin / sitagliptin) and get medical help right away if you have signs of ketoacidosis. These can include severe dehydration, like feeling very thirsty or having a very dry mouth. Other signs can be nausea, vomiting, stomach pain, tiredness, and shortness of breath.
Some people taking sitagliptin, which is in Steglujan, have had pancreatitis (or inflammation of the pancreas). This can sometimes cause damage to the pancreas and can be serious. It's not clear if your risk is higher if you've had this problem in the past. But let your prescriber know if you have a history of pancreatitis to be safe.

Steglujan (ertugliflozin / sitagliptin) can make your body lose fluid. This can sometimes lead to low blood pressure and make you feel dizzy. Sit or lie down if you get dizzy, lightheaded, or tired. Make sure to tell your prescriber if this happens.
Some people who took SGLT2 inhibitors, like ertugliflozin in Steglujan, have had sudden kidney problems. It can make problems worse in people who already have kidney issues.
Before starting Steglujan (ertugliflozin / sitagliptin), tell your prescriber if you have kidney problems. Your prescriber might check your kidneys with blood tests before and during treatment. This helps make sure your kidneys are okay and it's safe for you to take the medication.
Call your care team right away if you're not urinating as much, have swelling in the legs, or feel short of breath. These could be signs of kidney problems.
Steglujan (ertugliflozin / sitagliptin) can raise your risk of getting urinary tract infections (UTIs). It can also make you more likely to get a genital infection like a yeast infection. Although rare, some people have gotten a very serious and dangerous genital infection called Fournier's gangrene.
Let a healthcare professional know right away if you have signs of a UTI. This can include feeling pain or burning when you urinate, needing to urinate often, or seeing blood in your urine. Also get medical advice if you think you have a genital infection. Look for signs like fever and itching, pain, soreness, redness, or swelling in that area. Your care team can help treat the problem.
Although rare, Steglujan (ertugliflozin / sitagliptin) might raise some people's risk of needing an amputation. In studies, amputations of the toe or foot were most common. People who needed amputation were more likely to have had a higher A1C from the start, an amputation in the past, or diabetic foot ulcer. The most common reasons for amputation were leg infections and foot ulcers.
Pay careful attention to your legs and feet while taking Steglujan (ertugliflozin / sitagliptin). Be sure to follow up with your care team for foot exams.
Tell your care team if you have any new pain, tenderness, sores, infections, or ulcers in your legs or feet. If this happens, you might need to stop taking Steglujan (ertugliflozin / sitagliptin). Your care team can help you manage foot problems or treat them before they get worse.
Some studies suggest that there might be a connection between medications like sitagliptin (which is in Steglujan) and a risk of heart failure for people with Type 2 diabetes and heart disease. It's not clear if Steglujan carries this risk.
Before starting Steglujan (ertugliflozin / sitagliptin), tell your prescriber your full medical history. This is especially important if you have heart or kidney problems. They can check your risk of heart failure.
Get medical help right away if you have signs of heart failure. Watch for shortness of breath, tiredness, sudden weight gain, or swelling in the feet.
Your blood sugar can drop too much if you take Steglujan (ertugliflozin / sitagliptin) with some other diabetes medications. Insulin is one common example. Others include sulfonylureas like glipizide and glinides like repaglinide. Your prescriber might lower the dose of these medications to prevent low blood sugar.
To be safe, be sure you know how to recognize the signs of low blood sugar. Watch for signs like feeling hungry, shaking, cranky, weak, dizzy, or confused. You might also sweat a lot if have a fast heartbeat. If this happens, eat or drink something sugary (like juice or hard candy) right away to get your sugar back up. Tell your care team if your sugar gets too low.
Some people who take DPP-4 inhibitors, like the sitagliptin in Steglujan, have had severe joint pain. It can show up anytime from a day to many years after starting the medication. Most times, the pain goes away after stopping the medication. If you have any pain in your joints, let your care team know right away.
Although rare, some people taking DDP-4 inhibitors, like the sitagliptin in Steglujan, got a skin problem called bullous pemphigoid. It can cause itchy skin, blistering rash, or sores. These symptoms usually go away once you stop taking the medication and get treated.
If you notice a rash with blisters or itchy skin, speak to a healthcare professional. You might need to stop taking Steglujan (ertugliflozin / sitagliptin) and see a dermatologist.
Some people can have a serious allergic reaction to Steglujan (ertugliflozin / sitagliptin). This can include a rash, peeling or blistering skin, swelling of the face or lips, or trouble breathing.

If this happens, stop taking Steglujan (ertugliflozin / sitagliptin) and get medical help right away.
Tell your prescriber if you've had an allergic reaction to other DPP-4 inhibitors. This includes medications like Tradjenta (linagliptin) or alogliptin (Nesina). You might be more likely to react to Steglujan because it contains a similar medication called sitagliptin.
