Linagliptin/metformin may rarely cause a serious and sometimes fatal condition called lactic acidosis. Most of these cases have occurred in diabetic patients who also have certain kidney problems. The risk of lactic acidosis may be greater if you have liver problems, kidney problems, or heart failure. The risk may also be greater in patients who are elderly or drink alcohol. Lab tests, including kidney function, may be performed while you take linagliptin/metformin.
Do not begin to take linagliptin/metformin if you are 80 years old or older, unless lab tests show that you do not have decreased kidney function. Do not take it if you have a severe infection, have low blood oxygen levels, or are dehydrated. Tell your doctor you take linagliptin/metformin before you have any surgery or lab procedures.
Contact your doctor right away if you notice symptoms such as muscle pain or tenderness; unusual drowsiness, dizziness, or light-headedness; slow or irregular heartbeat; fast or difficult breathing; sudden stomach or bowel problems with nausea and vomiting; or unusual weakness or tiredness. Contact your doctor right away if you start to feel unusually cold, especially in your arms or legs, or if you have a general feeling of being unwell.
Linagliptin/ metformin is used for:
Treating type 2 diabetes in certain patients. It is used along with diet and exercise.
Linagliptin/metformin is a dipeptidyl peptidase-4 (DPP-4) inhibitor and biguanide combination. It works by increasing the amount of insulin released by your body. It decreases the amount of sugar made by your body. It also helps make your body more sensitive to the insulin that you naturally produce.

Important safety information:

- Do not drink large amounts of alcohol while you use linagliptin/metformin. Talk to your doctor or health care provider before you drink alcohol while you use linagliptin/metformin.
- Do NOT take more than the recommended dose without checking with your doctor.
- Tell your doctor or dentist that you take linagliptin/metformin before you receive any medical or dental care, emergency care, or surgery.
- If vomiting or diarrhea occurs, you will need to take care not to become dehydrated. Contact your doctor for instructions.
- Carry an ID card at all times that says you have diabetes. Check your blood sugar levels as directed by your doctor. If they are often higher or lower than they should be and you take linagliptin/metformin exactly as prescribed, tell your doctor.
- It may be harder to control your blood sugar during times of stress such as fever, infection, injury, or surgery. Talk with your doctor about how to control your blood sugar if any of these occur. Do not change the dose of your medicine without checking with your doctor.
- Linagliptin/metformin usually does not cause low blood sugar. However, low blood sugar may occur when it is used along with certain other medicines for diabetes (eg, sulfonylureas). Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your heart beat faster; make your vision change; give you a headache, chills, or tremors; or make you hungrier. It is a good idea to carry a reliable source of glucose (eg, tablets, gel) to treat low blood sugar. If this is not available, you should eat or drink a quick source of sugar like table sugar, honey, candy, orange juice, or non-diet soda. This will raise your blood sugar level quickly. Tell your doctor right away if this happens. To prevent low blood sugar, eat meals at the same time each day and do not skip meals.
- Metformin may commonly cause stomach upset, indigestion, nausea, vomiting, or diarrhea at the beginning of treatment. If you develop unusual or unexpected stomach problems, or if you develop stomach problems later during treatment, contact your doctor at right away. This may be a sign of lactic acidosis.
- Severe and sometimes fatal inflammation of the pancreas (pancreatitis) has been reported in patients taking linagliptin/metformin. Discuss any questions or concerns with your doctor. Contact your doctor immediately if you develop severe or persistent stomach or back pain with or without nausea or vomiting.
- Lab tests, including kidney function, fasting blood glucose, hemoglobin A1c, and complete blood cell counts, may be performed while you use linagliptin/metformin. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Use linagliptin/metformin with caution in the ELDERLY; they may be more sensitive to its effects. Low blood sugar levels may also be more difficult to recognize in elderly patients.
- PREGNANCY AND BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of taking linagliptin/metformin while you are pregnant. Linagliptin/metformin is found in breast milk. If you are or will be breast-feeding while you take linagliptin/metformin, check with your doctor. Discuss any possible risks to your baby.
