Sitagliptin/simvastatin is used for:
Treating type 2 diabetes and lowering high cholesterol and triglycerides in certain patients. It also increases high-density lipoprotein (HDL) ("good") cholesterol levels. It is used along with diet and exercise. It is used in certain patients to reduce the risk of heart attack, stroke, and death due to coronary heart disease. It is also used to reduce the need for medical procedures to open blocked blood vessels. It may also be used for other conditions as determined by your doctor.
Sitagliptin/simvastatin is a dipeptidyl peptidase-4 (DPP-4) inhibitor and HMG-CoA reductase inhibitor (statin) combination. The DPP-4 inhibitor works by increasing the amount of insulin released by your body and decreasing the amount of sugar made by your body. The statin works by reducing the production of certain fatty substances in the body, including cholesterol.

- Swallow sitagliptin/simvastatin whole. Do not break, crush, or chew before swallowing. Tell your doctor if you cannot swallow tablets whole.
- Eating grapefruit or drinking grapefruit juice may increase the amount of sitagliptin/simvastatin in your blood, which may increase your risk for serious side effects. The risk may be greater with large amounts of grapefruit or grapefruit juice. Avoid large amounts of grapefruit or grapefruit juice (eg, more than 1 quart daily).

Ask your health care provider any questions you may have about how to use sitagliptin/simvastatin.
Important safety information:
- Sitagliptin/simvastatin may cause liver problems. Rarely, severe and sometimes fatal liver failure has been reported in patients taking sitagliptin/simvastatin. Your risk of developing liver problems may be greater if you drink alcohol daily or in large amounts with sitagliptin/simvastatin, or if you have a history of liver problems. Check with your doctor before drinking alcohol while you are taking sitagliptin/simvastatin. Tell your doctor right away if you experience symptoms of liver problems (eg, yellowing of the skin or eyes; dark urine; pale stools; severe or persistent nausea, loss of appetite, or stomach pain; unusual tiredness).
- Carry an ID card at all times that says you have diabetes.
- Follow the diet and exercise program given to you by your health care provider. Proper diet, regular exercise, and regular blood sugar testing are important for best results with sitagliptin/simvastatin.
- 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/simvastatin 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.
- Tell your doctor or dentist that you take sitagliptin/simvastatin before you receive any medical or dental care, emergency care, or surgery. Sitagliptin/simvastatin may need to be stopped for a few days before certain types of surgery.
- Do NOT take more than the recommended dose without checking with your doctor.
- Muscle problems (myopathy) may occur with sitagliptin/simvastatin. The risk of muscle problems may be greater in people who take higher doses of sitagliptin/simvastatin, in people older than 64 years old, in women, or in people who have kidney problems or low thyroid function. It may also be greater in those who take it with certain other medicines (eg, niacin), especially in Chinese patients. Tell your doctor right away if you notice any unexplained muscle pain, tenderness, or weakness, especially if you also have a fever or general body discomfort. Tell your doctor if you have muscle problems that persist even after your doctor has told you to stop taking sitagliptin/simvastatin.
- Sitagliptin/simvastatin 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, insulin, 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 nondiet 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.
- Severe and sometimes fatal inflammation of the pancreas (pancreatitis) has been reported in patients taking sitagliptin/simvastatin. 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.
- Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Rarely, changes to the skin, hair, and nails (eg, discoloration, dryness, hair loss) may occur. Check with your doctor if these effects become bothersome or cause you concern.
- Lab tests, including blood cholesterol levels, blood glucose, hemoglobin A1c, liver and kidney function, and creatine phosphokinase (CPK) blood levels, may be performed while you use sitagliptin/simvastatin. 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/simvastatin with caution in the ELDERLY; they may be more sensitive to its effects, especially muscle problems.
- Sitagliptin/simvastatin should be used with extreme caution in CHILDREN younger than 18 years old; safety and effectiveness in children have not been confirmed.
- Women who are able to become pregnant should use effective birth control while taking sitagliptin/simvastatin. Check with your doctor if you have questions about using birth control.
