Alogliptin and metformin (Oral)
al-oh-GLIP-tin BEN-zoe-ate, met-FOR-min hye-droe-KLOR-ide
Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. Symptoms included malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Laboratory abnormalities included elevated blood lactate levels, anion gap acidosis, an increased lactate/pyruvate ratio, and metformin plasma levels generally greater than 5 mcg/mL. Risk factors include renal impairment, concomitant use of certain drugs (eg, carbonic anhydrase inhibitors), age 65 years or greater, radiological studies with contrast, surgery and other procedures, hypoxic states, excessive alcohol intake, and hepatic impairment. If lactic acidosis is suspected, immediately discontinue alogliptin/metformin and institute general supportive measures in a hospital setting; prompt hemodialysis is recommended .

Uses For This Medicine
Alogliptin and metformin combination may be used alone or together with other medicines and with a proper diet and exercise to treat high blood sugar levels caused by type 2 diabetes. Alogliptin 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 sugar (glucose) when there is too much sugar in the blood. Metformin reduces the absorption of sugar from the stomach, reduces the release of stored sugar from the liver, and helps your body use sugar better. Alogliptin and metformin does not help patients who have insulin-dependent or type 1 diabetes.
Alogliptin and metformin is available only with your doctor's prescription.

It is very important that your doctor check your progress at regular visits to make sure that alogliptin and metformin is working properly and to decide if you should continue to take it. Blood and urine tests may be needed to check for unwanted effects.
Under certain conditions, too much metformin can cause lactic acidosis. The symptoms of lactic acidosis are severe and quick to appear, and 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 get immediate emergency medical help.
Pancreatitis (swelling and inflammation of the pancreas) may occur while you are using alogliptin and metformin. Check with your doctor right away if you have a sudden and severe stomach pain, chills, constipation, nausea, vomiting, loss of appetite, fever, or lightheadedness.
If you are rapidly gaining weight, having shortness of breath, chest pain, extreme tiredness or weakness, irregular breathing, irregular heartbeat, or excessive swelling of the hands, wrist, ankles, or feet, check with your doctor immediately. These may be symptoms of a heart problem.
Alogliptin and metformin may cause serious allergic reactions, including anaphylaxis, angioedema, or certain skin conditions (eg, Stevens-Johnson syndrome). These reactions can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, blistering, peeling, or loosening of the skin, fever or chills, trouble breathing or swallowing, or any swelling of your hands, face, mouth, or throat while you are using alogliptin and metformin.

It is important that you learn which symptoms you usually have so you can treat it quickly. Talk to your doctor about the best way to treat low blood sugar.
Hyperglycemia (high blood sugar) may occur if you do not take enough or skip a dose of your medicine, overeat or do not follow your meal plan, have a fever or infection, or do not exercise as much as usual. High blood sugar can be very serious and must be treated right away. It is important that you learn which symptoms you have in order to treat it quickly. Talk to your doctor about the best way to treat high blood sugar.
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. It is a good idea to wear a medical identification (ID) bracelet or neck chain at all times. Also, carry an ID card in your wallet or purse that says you have diabetes with a list of all your medicines.
