What is Synjardy XR?
Synjardy XR are oral diabetes medicines that help control blood sugar levels.
Synjardy XR may also be used for purposes not listed in this medication guide.
You should not use this medicine if you have severe kidney disease or diabetic ketoacidosis (call your doctor for treatment).
You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. Call your doctor or get emergency medical help if you have unusual muscle pain, trouble breathing, stomach pain, dizziness, feeling cold, or feeling very weak or tired.
Before taking this medicine
You should not use this medicine if you are allergic to empagliflozin (Jardiance, Glyxambi) or metformin, or if you have severe kidney disease or diabetic ketoacidosis (call your doctor for treatment with insulin).
Tell your doctor if you have ever had:
liver or kidney disease;
a bladder infection or urination problems;
problems with your pancreas, including surgery; or
if you are on a low-salt diet.
You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. This may be more likely if you have other medical conditions, a severe infection, chronic alcoholism, or if you are 65 or older. Ask your doctor about your risk.
Tell your doctor right away if you become pregnant. Empagliflozin may harm the unborn baby if you take this medicine during your second or third trimester.
Metformin may stimulate ovulation in a premenopausal woman and may increase the risk of unintended pregnancy. Talk to your doctor about your risk.
You should not breast-feed while using this medicine.
Synjardy XR is not approved for use by anyone younger than 18 years old.
How should I take Synjardy XR?
Your doctor may perform kidney function tests before you start taking Synjardy XR.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
Take this medicine with food to prevent upset stomach.
Do not crush, chew, or break an extended-release tablet. Swallow it whole.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, and feeling shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.
Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and 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, blurred vision, headache, and tiredness.
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.
Your doctor may have you take extra vitamin B12 while you are taking Synjardy XR. Take only the amount of vitamin B12 that your doctor has prescribed.
Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking this medicine, which can lead to severely low blood pressure or a serious electrolyte imbalance.
If you need surgery or medical tests, tell any doctor who treats you that you are using Synjardy XR.
Synjardy XR is only part of a treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
Store at room temperature, away from moisture and heat.
What happens if I miss a dose?
Take the medicine (with food) as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. You may have severely low blood sugar (extreme weakness, nausea, tremors, sweating, confusion, trouble speaking, fast heartbeats, or seizure).
What should I avoid while taking Synjardy XR?
Avoid drinking alcohol. It lowers blood sugar and may increase your risk of lactic acidosis.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
