What is linagliptin and metformin?
Linagliptin and metformin are oral diabetes medicines that help control blood sugar levels. Metformin works by decreasing glucose (sugar) production in the liver and decreasing absorption of glucose by the intestines. Linagliptin works by regulating the levels of insulin your body produces after eating.
Linagliptin and metformin is a combination medicine used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus. This medicine is not for treating type 1 diabetes.
Linagliptin and metformin may also be used for purposes not listed in this medication guide.
What is the most important information I should know about linagliptin and metformin?
You should not use this medicine if you have severe kidney disease or diabetic ketoacidosis (call your doctor for treatment).
Some people develop lactic acidosis while taking metformin. Early symptoms may get worse over time and this condition can be fatal. Stop taking this medicine and get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, trouble breathing, stomach pain, nausea, and feeling very weak or tired.

Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, fast heart rate, and feeling anxious or 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.
Your doctor may want you to stop taking this medicine for a short time if you become ill, have a fever or infection, or if you have surgery or a medical emergency.
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.
