Synjardy XR Overview

Reviewed: March 7, 2017
Updated: 

Synjardy XR is a prescription medication used to treat type 2 diabetes. It is a single product containing 2 medications: empagliflozin and metformin.

Empagliflozin belongs to a group of drugs called sodium-glucose cotransporter 2 (SGLT2) inhibitors. These drugs work by stopping the reabsorption of glucose by the kidney, increasing glucose excretion from the body, and lowering blood sugar levels. Metformin belongs to a group of drugs called biguanides. These drugs work by helping your body respond better to the insulin it makes naturally, decreasing the amount of sugar your liver makes and decreasing the amount of sugar your intestines absorb.

This medication comes in tablet form and is taken once daily with a meal in the morning.

Swallow the tablet whole; do not split, crush, dissolve, or chew.

Common side effects include diarrhea, nausea/vomiting, gas, stomach discomfort, indigestion, weakness, and headache. Synjardy XR may also cause urinary tract infections and female genital yeast infections.

Synjardy XR can also cause low blood sugar, which can cause drowsiness and dizziness. Do not drive or operate heavy machinery until you know how Synjardy XR affects you.

  • If acidosis is suspected, Synjardy XR should be discontinued and the patient should be hospitalized immediately.
