Sitagliptin

Sitagliptin is used for:

Treating type 2 diabetes in certain patients. It is used along with diet and exercise.

Sitagliptin is a dipeptidyl peptidase-4 inhibitor and biguanide combination. It works by increasing insulin release. It decreases the amount of sugar that the liver produces and the intestines absorb. It also helps to make your body more sensitive to the insulin that you naturally produce.

• you have type 1 diabetes
• you have congestive heart failure that is treated by medicine
• you have a severe infection, low blood oxygen levels, kidney or liver problems, or high blood ketone or acid levels (eg, diabetic ketoacidosis), or you are severely dehydrated
• you have had a stroke or a recent heart attack, or you are in shock
• you are at least 80 years old and have not had a kidney function test
• you will be having surgery or certain lab procedures

Contact your doctor or health care provider right away if any of these apply to you.

Important safety information:

• Dizziness may occur while you are taking Sitagliptin . This effect may be worse if you take it with alcohol or certain medicines. Use Sitagliptin with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
• Follow the diet and exercise program given to you by your health care provider.
• Do not drink large amounts of alcohol while you use Sitagliptin . Talk to your doctor or health care provider before you drink alcohol while you use Sitagliptin .
• Do NOT take more than the recommended dose without checking with your doctor.
• Tell your doctor or dentist that you take Sitagliptin 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 Sitagliptin exactly as prescribed, tell your doctor.
• Sitagliptin does not usually lower your blood sugar levels. Low blood sugar may be more likely to occur if you skip a meal, exercise heavily, or drink alcohol. It may also be more likely if you take Sitagliptin along with certain medicines for diabetes (eg, sulfonylureas, insulin). It is a good idea to carry a reliable source of glucose (eg, tablets or 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.
• Fever, infection, injury, or surgery may increase your risk for high or low blood sugar levels. If any of these occur, check your blood sugar closely and tell your doctor right away.
• Sitagliptin 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 once. This may be a sign of lactic acidosis.
• Lab tests, including kidney function, fasting blood glucose, hemoglobin A_1c, and blood counts, may be performed while you use Sitagliptin . These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
• Use Sitagliptin 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 the elderly.
• Sitagliptin should be used with extreme caution in CHILDREN younger than 18 years old; safety and effectiveness in these children have not been confirmed.
• PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Sitagliptin while you are pregnant. It is not known if Sitagliptin is found in breast milk. If you are or will be breast-feeding while you use Sitagliptin , check with your doctor. Discuss any possible risks to your baby.

When used for long periods of time, Sitagliptin may not work as well. If your blood sugar has been under control and then becomes hard to manage, contact your doctor. Do not change the dose of your medicine without checking with your doctor.
