Januvia (sitagliptin) is a medication taken by Type 2 diabetic patients once a day. It works by:

  • Increasing insulin levels made by the pancreas to counteract high blood sugar levels
  • Lowering the amount of sugar made by the liver

The medication works by controlling the levels of insulin your body makes after you eat. The medication can be taken with or without food. For best results, diabetics who take this medication are also expected to eat a proper diet and exercise.

Essential Facts to Know About Januvia

Beware of some of the symptoms of pancreatitis. If you have significant pain in your abdomen that doesn't cease, you should stop taking the drug and call your doctor right away. In some people the pain seems to be going through the abdomen and into the back. Vomiting may or may not occur. Pancreatitis means inflammation of the pancreas and should be treated immediately.

Pancreatitis occurs when the enzymes that should do their work in the small intestine instead are activated when they are in the pancreas. Serious pancreatitis can lead to severe illness and even death.

When you see your doctor, you need to tell him or her if you have had pancreatitis, as well as:

  • Gallstones
  • High levels of triglycerides in your blood
  • Difficulties with your kidneys (patients with these problems may need to have dialysis)
  • A history of alcoholism

If you are pregnant or breast feeding, you should tell your doctor. It is not known if Januvia can harm the fetus or pass through breast milk.

Some medicines, such as a sulfonylurea or insulin, may lower blood sugar and if they are taken when a patient is on Januvia, blood sugar levels may need to be lowered by decreasing the dose of these other medicines.

Signs of Low Blood Sugar

You may recognize lower levels in your blood sugar if some of the following symptoms occur at the same time:

  • Perspiring
  • Feeling sleepy
  • Weakness
  • Feeling unsteady
  • Problems thinking clearly
  • Irritability
  • Hunger
  • Rapid heartbeat
  • Feeling jumpy or on edge

Some Side Effects of Januvia

Among the most common reactions to Januvia are:

  • Cold symptoms (stuffy or running nose or sore throat)
  • Headache
  • Queasiness
  • Diarrhea
  • Swelling of the hands or legs if you also take Avandia (rosiglitazone)

Pancreatitis is the most severe reaction to Januvia. Some patients taking Januvia also have been diagnosed with pancreatic cancer. To learn more about the connection between Januvia and pancreatic cancer, click here.
