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

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

1.

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

•

have 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 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 KOMBIGLYZE XR for a while if you have any of these things.

KOMBIGLYZE XR can have other serious side effects. See “What are the possible side effects of KOMBIGLYZE XR?

2.

Inflammation of the pancreas (pancreatitis) which may be severe and lead to death.
Certain medical problems make you more likely to get pancreatitis.

Tell your healthcare provider if you have ever had:

•

inflammation of your pancreas (pancreatitis)

•

a history of alcoholism

The pain may be felt going from your abdomen through to your back. The pain may happen with or without vomiting. These may be symptoms of pancreatitis.

3.

Heart failure. Heart failure means your heart does not pump blood well enough.

What is type 2 diabetes?

Type 2 diabetes is a condition in which your body does not make enough insulin, and the insulin that your body produces does not work as well as it should. Your body can also make too much sugar. When this happens, sugar (glucose) builds up in the blood. This can lead to serious medical problems.

The main goal of treating diabetes is to lower your blood sugar so that it is as close to normal as possible. High blood sugar can be lowered by diet and exercise, and by certain medicines when necessary.

Talk to your healthcare provider about how to prevent, recognize, and take care of low blood sugar (hypoglycemia), high blood sugar (hyperglycemia), and problems you have because of your diabetes.
