    • along with diet and exercise to improve blood sugar in adults with type 2 diabetes,

  • Synjardy XR is not for people with type 1 diabetes.
  • Synjardy XR is not for people with diabetic ketoacidosis (increased ketones in the blood or urine).

What is the most important information I should know about Synjardy XR?

Serious side effects can happen in people taking Synjardy XR, including:

Lactic Acidosis. Metformin, one of the medicines in Synjardy XR can cause a rare but serious condition called lactic acidosis (a build-up of lactic acid in the blood) that can cause death. Lactic acidosis is a medical emergency and must be treated in a hospital.

Call your doctor right away if you have any of the following symptoms, which could be signs of lactic acidosis:

  • you feel cold in your hands or feet
  • you feel dizzy or lightheaded
  • you have a slow or irregular heartbeat
  • you feel very weak or tired
  • you have unusual (not normal) muscle pain
  • you have trouble breathing
  • you feel sleepy or drowsy
  • you have stomach pains, nausea or vomiting

Most people who have had lactic acidosis with metformin have other things that, combined with metformin, led to the lactic acidosis. Tell your doctor if you have any of the following, because you have a higher chance for getting lactic acidosis with Synjardy XR if you:

  • have moderate to severe kidney problems or your kidneys are affected by certain x-ray tests that use injectable dye.
  • have liver problems
  • drink alcohol very often, or drink a lot of alcohol in the short-term ("binge" drinking)
  • get dehydrated (lose a large amount of body fluids). This can happen if you are sick with a fever, vomiting, or diarrhea. Dehydration can also happen when you sweat a lot with activity or exercise and do not drink enough fluids.
  • have surgery
  • have a heart attack, severe infection, or stroke

The best way to keep from having a problem with lactic acidosis from metformin is to tell your doctor if you have any of the problems in the list above. Your doctor may decide to stop your Synjardy XR for a while if you have any of these things.

Synjardy XR can have other serious side effects. See "What are the possible side effects of Synjardy XR?"

Who should not take Synjardy XR?

Do not take Synjardy XR if you:

  • have moderate to severe kidney problems or are on dialysis
  • have a condition called metabolic acidosis or diabetic ketoacidosis (increased ketones in the blood or urine)

Synjardy XR may cause serious side effects, including:

  • See "What is the most important information I should know about Synjardy XR?"
  • Dehydration. Synjardy XR can cause some people to have dehydration (the loss of body water and salt). Dehydration may cause you to feel dizzy, faint, light-headed, or weak, especially when you stand up (orthostatic hypotension). You may be at higher risk of dehydration if you:

Ketoacidosis has happened in people who have type 1 diabetes or type 2 diabetes, during treatment with empagliflozin, one of the medicines in Synjardy XR. Ketoacidosis has also happened in people with diabetes who were sick or who had surgery during treatment with Synjardy XR. Ketoacidosis is a serious condition, which may need to be treated in a hospital. Ketoacidosis may lead to death. Ketoacidosis can happen with Synjardy XR even if your blood sugar is less than 250 mg/dL. Stop taking Synjardy XR and call your doctor right away if you get any of the following symptoms:

Tell your doctor 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 also may have a fever, back pain, nausea or vomiting.
  • Low blood sugar (hypoglycemia). If you take Synjardy XR 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 medicine or insulin may need to be lowered while you take Synjardy XR. Signs and symptoms of low blood sugar may include:
    • headache
    • drowsiness
    • weakness
    • irritability

Necrotizing fasciitis of the perineum has happened in women and men who take empagliflozin, one of the medicines in Synjardy XR. 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 a fever 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)

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 the 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, or pain in the skin around the 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 medication and your symptoms do not go away.
  • Allergic (hypersensitivity) reactions. Serious allergic reactions have happened in people who are taking empagliflozin, one of the medicines in Synjardy XR. Symptoms may include
