Metformin and sitagliptin combination is used to treat a type of diabetes mellitus (sugar diabetes) called type 2 diabetes. Normally, after you eat, your pancreas releases insulin to help your body store excess sugar for later use. This process occurs during normal digestion of food. In type 2 diabetes, your body does not work properly to store the excess sugar and the sugar remains in your blood. Chronic high blood sugar can lead to serious health problems in the future.
Proper diet is the first step in managing type 2 diabetes, but often medicines are needed to help your body. Metformin reduces the absorption of sugar, reduces the release of stored sugar from the liver, and helps your body's cells use sugar better. Sitagliptin helps to control blood sugar levels by increasing substances in the body that make the pancreas release more insulin. It also signals the liver to stop producing glucose when there is too much sugar in the blood.
Metformin and sitagliptin combination does not help patients who have insulin-dependent or type 1 diabetes, because they cannot produce insulin from their pancreas. Their blood glucose is best controlled by insulin injections.

Under certain conditions, too much metformin and sitagliptin can cause lactic acidosis. Symptoms of lactic acidosis are severe and quick to appear. They usually occur when other health problems not related to the medicine are present and are very severe, such as a heart attack or kidney failure. Symptoms of lactic acidosis include abdominal or stomach discomfort; decreased appetite; diarrhea; fast, shallow breathing; a general feeling of discomfort; muscle pain or cramping; and unusual sleepiness, tiredness, or weakness.
If symptoms of lactic acidosis occur, you should check your blood sugar and get immediate emergency medical help.
This medicine may cause hypoglycemia (low blood sugar). Low blood sugar can also occur if you delay or miss a meal or snack, exercise more than usual, drink alcohol, cannot eat because of nausea or vomiting, take certain medicines, or take this medicine with another type of diabetes medicine. Symptoms of low blood sugar must be treated before they cause you to pass out (unconsciousness). People feel different symptoms with low blood sugar. It is important that you learn which symptoms you usually have so you can treat it quickly.
Symptoms of low blood sugar include anxiety; behavior changes similar to being drunk; blurred vision; cold sweats; confusion; cool, pale skin; difficulty with thinking; drowsiness; excessive hunger; fast heartbeat; headaches that continue; nausea; nervousness; nightmares; restless sleep; shakiness; slurred speech; or unusual tiredness or weakness.
If symptoms of low blood sugar occur, eat glucose tablets or gel, corn syrup, honey, or sugar cubes; or drink fruit juice, non-diet soft drinks, or sugar dissolved in water. Also, check your blood for low blood sugar. Glucagon is used in emergency situations when severe symptoms such as seizures (convulsions) or unconsciousness occur. Have a glucagon kit available, along with a syringe and needle, and know how to use it. Members of your family should also know how to use it.
Hyperglycemia (high blood sugar) may occur if you do not take enough or skip a dose of your diabetes medicine, overeat or do not follow your diet plan, have a fever or infection, or do not exercise as much as usual.
Symptoms of high blood sugar include blurred vision; drowsiness; dry mouth; flushed, dry skin; fruit-like breath odor; increased urination (frequency and amount); ketones in the urine; loss of appetite; sleepiness; stomachache, nausea, or vomiting; tiredness; troubled breathing (rapid and deep); unconsciousness (passed out); or unusual thirst.
If symptoms of high blood sugar occur, check your blood sugar level and then call your doctor for instructions.
There may be a time when you need emergency help for a problem caused by your diabetes. You need to be prepared for these emergencies.
