What is Steglujan?

Steglujan contains a combination of ertugliflozin and sitagliptin. Ertugliflozin and sitagliptin help control blood sugar levels. Ertugliflozin works by helping the kidneys get rid of glucose from your bloodstream. Sitagliptin works by regulating the levels of insulin your body produces after eating.

Steglujan is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus.

Steglujan is not for treating type 1 diabetes.

Warnings

You should not use Steglujan if you have severe kidney disease, if you are on dialysis, or if you have diabetic ketoacidosis.

This medicine can make you dehydrated, which could cause you to feel weak or dizzy (especially when you stand up).

Stop taking Steglujan and call your doctor right away if you have symptoms of pancreatitis: severe pain in your upper stomach spreading to your back, with or without nausea and vomiting.

In rare cases, this medicine can cause serious infections in the penis or vagina. Get medical help right away if you have burning, itching, odor, discharge, pain, tenderness, redness or swelling of the genital or rectal area, fever, or if you don't feel well.

Before taking this medicine

You should not use Steglujan if you are allergic to ertugliflozin o sitagliptin, or if you have:

• severe kidney problems, end stage renal disease, or if you are on dialysis.

To make sure Steglujan is safe for you, tell your doctor if you have ever had:

• diabetic ketoacidosis;

• liver or kidney disease;

• a bladder infection or urination problems;

• problems with your pancreas, including surgery;

• a diabetic foot ulcer or amputation;

• heart problems, high or low blood pressure;

• blood circulation problems, especially in your legs;

• nerve damage in your legs;

• gallstones;

• high triglycerides (a type of fat in blood);

• alcoholism;

• type 1 diabetes; or

• if you are eating less, there is a change in your diet, or you are on a low salt diet.

Follow your doctor's instructions about using Steglujan if you are pregnant. Blood sugar control is very important during pregnancy, and your dose needs may be different during each trimester.

You should not use Steglujan during the second or third trimester of pregnancy.

You should not breastfeed while using this medicine.

Steglujan is not approved for use by anyone younger than 18 years old.

How should I take Steglujan?

Steglujan is usually taken once per day in the morning. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

You may take Steglujan with or without food.

Call your doctor if you are sick with vomiting or diarrhea, if you consume less food or fluid than usual, or if you are sweating more than usual.

Tell your doctor if you have a planned surgery.

Your blood sugar will need to be checked often, and you may also need to test the level of ketones your urine. Ertugliflozin can cause life-threatening ketoacidosis (too much acid in the blood). Even if your blood sugar is normal, contact your doctor if a urine test shows that you have ketones in the urine.

You may have low blood sugar (hypoglycemia) and feel very hungry, dizzy, irritable, confused, anxious, or shaky. To quickly treat hypoglycemia, eat or drink a fast-acting source of sugar (fruit juice, hard candy, crackers, raisins, or non-diet soda).

Your doctor may prescribe a glucagon injection kit in case you have severe hypoglycemia. Be sure your family or close friends know how to give you this injection in an emergency.

Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination.

Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.

This medicine can cause unusual results with certain lab tests. Tell any doctor who treats you that you are using Steglujan.

Store at room temperature away from moisture and heat. Keep unused tablets in the foil blister pack in its original container.
