What is the most important information I should know about Synjardy?
Serious side effects can happen in people taking Synjardy, including:
Lactic Acidosis. Metformin, one of the medicines in Synjardy 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 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 for a while if you have any of these things.
Synjardy can have other serious side effects. See "What are the possible side effects of Synjardy?"
Who should not take Synjardy?
Do not take Synjardy if you:
- have moderate to severe kidney problems or are on dialysis

What should I avoid while taking Synjardy?
Avoid drinking alcohol very often, or drinking a lot of alcohol in a short period of time ("binge" drinking). It can increase your chances of getting serious side effects.
Synjardy may cause serious side effects, including:
- See "What is the most important information I should know about Synjardy?"
- Dehydration. Synjardy 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:
- have low blood pressure
- have kidney problems
- are 65 years of age or older
- are on low sodium (salt) diet
- take medicines to lower your blood pressure, including diuretics (water pills)
- Ketoacidosis (increased ketones in your blood or urine). Ketoacidosis has happened in people who have type 1 diabetes or type 2 diabetes, during treatment with empagliflozin, one of the medicines in Synjardy. Ketoacidosis has also happened in people with diabetes who were sick or who had surgery during treatment with Synjardy. Ketoacidosis is a serious condition, which may need to be treated in a hospital. Ketoacidosis may lead to death. Ketoacidosis can happen with Synjardy even if your blood sugar is less than 250 mg/dL. Stop taking Synjardy and call your doctor right away if you get any of the following symptoms:
- stomach-area (abdominal) pain
- trouble breathing
If you get any of these symptoms during treatment with Synjardy, if possible, check for ketones in your urine, even if your blood sugar is less than 250 mg/dL.
- Kidney problems. Sudden kidney injury has happened to people taking Synjardy. Talk to your doctor right away if you:
- reduce the amount of food or liquid you drink for example, if you are sick or cannot eat or
- start to lose liquids from your body for example, from vomiting, diarrhea or being in the sun too long
- Serious urinary tract infections. Serious urinary tract infections that may lead to hospitalization have happened in people who are taking empagliflozin, one of the medicines in Synjardy. 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 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. Signs and symptoms of low blood sugar may include:
- fast heartbeat
- shaking or feeling jittery
- 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 empagliflozin, one of the medicines in Synjardy. 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
- redness of skin (erythema)
- Vaginal yeast infection. Women who take Synjardy 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), or vaginal itching.
- Yeast infection of the penis (balanitis). Men who take Synjardy 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 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. Symptoms may include:
- swelling of your face, lips, throat and other areas of your skin
- difficulty with swallowing or breathing.
- raised, red areas on your skin (hives)
If you have any of these symptoms, stop taking Synjardy and call your doctor right away or go to the nearest hospital emergency room.
- Low vitamin B12 (vitamin B12 deficiency). Using metformin for long periods of time may cause a decrease in the amount of vitamin B12 in your blood, especially if you have had low vitamin B12 blood levels before. Your doctor may do blood tests to check your vitamin B12 levels.
- Increased fats in your blood (cholesterol)
The most common side effects of Synjardy include stuffy or runny nose and sore throat.
These are not all the possible side effects of Synjardy. For more information, ask your doctor or pharmacist.
