Read this Medication Guide carefully before you start taking STEGLATRO and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or your treatment.
What is the most important information I should know about STEGLATRO? STEGLATRO may cause serious side effects, including:
  • Diabetic ketoacidosis (increased ketones in your blood or urine) in people with type 1 diabetes and other ketoacidosis. STEGLATRO can cause ketoacidosis that can be life-threatening and may lead to death. Ketoacidosis is a serious condition which needs to be treated in a hospital. People with type 1 diabetes have a high risk of getting ketoacidosis. People with type 2 diabetes or pancreas problems also have an increased risk of getting ketoacidosis. Ketoacidosis can also happen in people who: are sick, cannot eat or drink as usual, skip meals, are on a diet high in fat and low in carbohydrates (ketogenic diet), take less than the usual amount of insulin or miss insulin doses, drink too much alcohol, have a loss of too much fluid from the body (volume depletion), or who have surgery. Ketoacidosis can happen even if your blood sugar is less than 250 mg/dL. Your healthcare provider may ask you to periodically check ketones in your urine or blood.
    Stop taking STEGLATRO and call your healthcare provider or get medical help right away if you get any of the following. If possible, check for ketones in your urine or blood, even if your blood sugar is less than 250 mg/dL:
  • nausea
  • vomiting
  • stomach-area (abdominal) pain
  • tiredness
  • trouble breathing
  • ketones in your urine or blood
  • Amputations. STEGLATRO may increase your risk of lower limb amputations.
    You may be at a higher risk of lower limb amputation if you:
    • have a history of amputation
    • have had blocked or narrowed blood vessels, usually in your leg
    • have damage to the nerves (neuropathy) in your leg
    • have had diabetic foot ulcers or sores
Call your healthcare provider right away if you have new pain or tenderness, any sores, ulcers, or infections in your leg or foot. Your healthcare provider may decide to stop your STEGLATRO for a while if you have any of these signs or symptoms. Talk to your healthcare provider about proper foot care.
  • Dehydration. STEGLATRO 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). There have been reports of sudden worsening of kidney function in people who are taking STEGLATRO.
You may be at risk of dehydration if you:
  • take medicines to lower your blood pressure, including water pills (diuretics)
  • are on a low sodium (salt) diet
  • have kidney problems
  • are 65 years of age or older
Talk to your healthcare provider about what you can do to prevent dehydration including how much fluid you should drink on a daily basis. Call your healthcare provider right away if you reduce the amount of food or liquid you drink, for example if you are sick or cannot eat, or you start to lose liquids from your body, for example from vomiting, diarrhea or being in the sun too long.
  • Vaginal yeast infection. 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). Swelling of an uncircumcised penis may develop that makes it difficult to pull back the skin around the tip of the penis. Other symptoms of yeast infection of the penis include:
  • redness, itching, or swelling of the penis
  • foul smelling discharge from the penis
  • rash of the penis
  • pain in the skin around your penis
Talk to your healthcare provider about what to do if you get symptoms of a yeast infection of the vagina or penis. Your healthcare provider may suggest you use an over-the-counter antifungal medicine. Talk to your healthcare provider right away if you use an over-the-counter antifungal medicine and your symptoms do not go away.
What is STEGLATRO?

How should I take STEGLATRO?
  • Take STEGLATRO by mouth 1 time in the morning each day, with or without food, exactly as your healthcare provider tells you to take it.
  • Your healthcare provider may tell you to take STEGLATRO along with other diabetes medicines. Low blood sugar can happen more often when STEGLATRO is taken with certain other diabetes medicines. See “What are the possible side effects of STEGLATRO?”.
  • If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take 2 doses of STEGLATRO at the same time. Talk with your healthcare provider if you have questions about a missed dose.
  • If you take too much STEGLATRO, call your healthcare provider or go to the nearest hospital emergency room right away.
  • When your body is under some types of stress, such as fever, trauma (such as a car accident), infection, or surgery, the amount of diabetes medicine you need may change. Tell your healthcare provider right away if you have any of these conditions and follow your healthcare provider’s instructions.
  • STEGLATRO will cause your urine to test positive for glucose.
  • Your healthcare provider may do certain blood tests before you start STEGLATRO and during treatment as needed. Your healthcare provider may change your dose of STEGLATRO based on the results of your blood tests.
What are the possible side effects of STEGLATRO?
STEGLATRO may cause serious side effects, including:

See "What is the most important information I should know about STEGLATRO?"
  • Serious urinary tract infections. Serious urinary tract infections that may lead to hospitalization have happened in people who are taking STEGLATRO. Tell your healthcare provider if you have any signs or symptoms of a urinary tract infection such as a burning feeling when passing urine, a need to urinate often, the need to urinate right away, pain in the lower part of your stomach (pelvis), or blood in the urine. Sometimes people may also have a fever, back pain, nausea, or vomiting.
  • Low blood sugar (hypoglycemia). If you take STEGLATRO with another medicine that can cause low blood sugar such as a sulfonylurea or insulin, your risk of getting low blood sugar is higher. The dose of your sulfonylurea or insulin may need to be lowered while you take STEGLATRO. Signs and symptoms of low blood sugar may include:
  • headache
  • confusion
  • hunger
  • shaking or feeling jittery
  • drowsiness
  • dizziness
  • fast heartbeat
  • weakness
  • sweating
  • irritability
  • A rare but serious bacterial infection that causes damage to the tissue under the skin (necrotizing fasciitis) in the area between and around the anus and genitals (perineum). Necrotizing fasciitis of the perineum has happened in women and men who take medicines that lower blood sugar in the same way as STEGLATRO. Necrotizing fasciitis of the perineum may lead to hospitalization, may require multiple surgeries, and may lead to death. Seek medical attention immediately if you have fever above 100.4°F or you are feeling very weak, tired or uncomfortable (malaise) and you develop any of the following symptoms in the area between and around your anus and genitals:
  • pain or tenderness
  • swelling
  • redness of skin (erythema)
  • Serious allergic reaction. If you have any symptoms of a serious allergic reaction, stop taking STEGLATRO and call your healthcare provider right away or go to the nearest hospital emergency room.
