If you need to have surgery or any type of x-ray or CT scan using a dye that is injected into your veins, you may need to temporarily stop taking this medicine. Be sure your caregivers know ahead of time that you are using Synjardy XR.

Tell your doctor if you have ever had:

You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. Ask your doctor about your risk.

Follow your doctor's instructions about using this medicine if you are pregnant or you become pregnant. Controlling diabetes is very important during pregnancy.

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

Metformin may stimulate ovulation in a premenopausal woman and may increase the risk of unintended pregnancy. Talk to your doctor about your risk.

How should I take 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 with meals.

Swallow the extended-release tablet whole and do not crush, chew, break, or dissolve it. Tell your doctor if you have trouble swallowing the tablet.

Your blood sugar will need to be checked often, and you may also need to test the level of ketones in your urine. Empagliflozin 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 high ketones in the urine.

Blood sugar can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals.

Low blood sugar (hypoglycemia) can make you feel very hungry, dizzy, irritable, or shaky. To quickly treat hypoglycemia, eat or drink hard candy, crackers, raisins, fruit juice, or non-diet soda. Your doctor may prescribe glucagon injection in case of severe hypoglycemia.

You may get dehydrated during prolonged illness. Call your doctor if you are sick with vomiting or diarrhea, or if you eat or drink less than usual.

Tell your doctor if you have a planned surgery.

Synjardy XR can affect the results of certain medical tests. Tell any doctor who treats you that you are using Synjardy XR.

Your doctor may have you take extra vitamin B12 while you are taking Synjardy XR. Take only the amount of vitamin B12 your doctor has prescribed.

Your treatment may also include diet, exercise, weight control, and special medical care.

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.

Overdose may cause lactic acidosis. Symptoms may include unusual muscle pain, trouble breathing, irregular heartbeats, or if you feel very weak.

What should I avoid while taking Synjardy XR?

Avoid drinking alcohol. It may increase your risk of lactic acidosis.

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy.

What other drugs will affect Synjardy XR?
