What is Januvia?
Januvia is an oral diabetes medicine that helps control blood sugar levels. It works by regulating the levels of insulin your body produces after eating.
Januvia is for people with type 2 diabetes (non-insulin-dependent) diabetes. It is sometimes used in combination with other diabetes medications, but is not for treating type 1 diabetes.
Januvia may also be used for purposes other than those listed here.
Important information about Januvia
Do not use Januvia if you are allergic to sitagliptin or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).
Before taking Januvia, tell your doctor if you have kidney disease, if you are on dialysis, or if you have a history of pancreatitis.
You may take this medicine with or without food. Follow your doctor's instructions.
Follow your doctor's instructions about any restrictions on food, beverages, or activity while you are taking Januvia.
Stop taking Januvia and call your doctor at once if you have severe pain in your upper stomach spreading to your back, nausea and vomiting, loss of appetite, or fast heart rate.
Take care not to let your blood sugar get too low. Low blood sugar (hypoglycemia) can occur if you skip a meal, exercise too long, drink alcohol, or are under stress. Symptoms include headache, hunger, weakness, sweating, tremor, irritability, or trouble concentrating. Carry hard candy or glucose tablets with you in case you have low blood sugar. Other sugar sources include orange juice and milk. Be sure your family and close friends know how to help you in an emergency.
Januvia is only part of a complete program of treatment that also includes diet, exercise, weight control, and possibly other medications. It is important to use this medicine regularly to get the most benefit. Get your prescription refilled before you run out of Januvia completely.
