What is the most important information I should know about JENTADUETO?

Serious side effects can happen in people taking JENTADUETO, including:

Stop taking JENTADUETO and call your doctor right away if you get any of the following symptoms of lactic acidosis:

  • have surgery
  • have a heart attack, severe infection, or stroke

What is type 2 diabetes?

Type 2 diabetes is a condition in which your body does not make enough insulin, and/or 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 to a normal level. High blood sugar can be lowered by diet and exercise, and by certain medicines when necessary.

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