What is sitagliptin?
Sitagliptin is an oral diabetes medicine that helps control blood sugar levels. It works by regulating the levels of insulin your body produces after eating.
Sitagliptin may also be used for purposes not listed in this medication guide.
Call your doctor if you have symptoms of heart failure--shortness of breath (even while lying down), swelling in your legs or feet, rapid weight gain.
Stop taking sitagliptin and call your doctor if you have symptoms of pancreatitis: severe pain in your upper stomach spreading to your back, with or without vomiting.
Before taking this medicine
Tell your doctor if you have ever had:
kidney disease (or if you are on dialysis);
high triglycerides (a type of fat in the blood);
Follow your doctor's instructions about using sitagliptin if you are pregnant. Blood sugar control is very important during pregnancy, and your dose needs may be different during each trimester.
Your name may need to be listed on a sitagliptin pregnancy registry when you start using this medicine.
It may not be safe to breast-feed a baby while you are using this medicine. Ask your doctor about any risks.

How should I take sitagliptin?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
You may take this medicine with or without food. Follow your doctor's instructions.
Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, and feeling shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.
Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and close friends know how to give you this injection in an emergency.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination, blurred vision, headache, and tiredness.
Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.
Sitagliptin is only part of a complete treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
Store at room temperature away from moisture, heat, and light.
What happens if I miss a dose?
Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. You may have signs of low blood sugar, such as extreme weakness, blurred vision, sweating, trouble speaking, tremors, stomach pain, confusion, and seizure (convulsions).
What should I avoid while taking sitagliptin?
Follow your doctor's instructions about any restrictions on food, beverages, or activity.
