Januvia Side Effects

The most serious side effects of Januvia would be life-threatening allergic reactions. If you have any of the following symptoms, you should stop taking the medication and call your doctor right away.

The primary symptoms of an allergic reaction include:

  • Rash
  • Hives
  • Swelling of the face, lips, tongue and throat that may make it hard to breathe or swallow

Serious Side Effects of Januvia

Pancreatitis: The development of pancreatitis is one of the most serious side effects of Januvia. The condition, an inflammation of the pancreas, can be serious and lead to death. Some medical conditions predispose you to pancreatitis. These include:

  • Previous occurrence of pancreatitis
  • Gallstones
  • History of alcoholism
  • High levels of triglycerides in your blood
  • Kidney problems

Another sign of pancreatitis is abdominal pain. This pain can be severe and can feel as if it's going through your stomach to your back. This is one of the hallmark symptoms of pancreatitis. The pain may or may not be accompanied by vomiting.

Pancreatic Cancer: Studies have shown that taking Januvia may lead to an increase in the risk for precancerous changes in the pancreas. According to reports, the FDA received 292 reports of pancreatic tumors (almost all being pancreatic cancer) in patients taking Januvia, Byetta or Victoza between Jan. 1, 2010 and June 30, 2012.

It is important for patients to note that symptoms of pancreatic cancer usually don't develop until the later stages of the cancer. Symptoms during the advances stages of cancer include:

  • Upper abdominal pain that radiates to the back
  • Loss of appetite
  • Weight loss
  • Blood clots
  • Jaundice (yellowing of the skin or eyes)
  • Depression

Low Blood Sugar: Low blood sugar may be another side effect of Januvia. If you take another medicine that lowers your blood sugar while you are taking Januvia, such as a sulfonylurea or insulin, your risk of having low blood sugar increases. You should be aware that the following may be signs of low blood sugar:

  • Feeling shaky or jittery
  • Headache
  • Fatigue
  • Confusion
  • Dizziness
  • Irritability
  • Increased hunger
  • Rapid heart beat
  • Perspiring

Kidney Problems: Kidney problems may also result from taking Januvia.

Less Serious, Common Side Effects

The most common side effects of Januvia are:

  • Cold
  • Sore throat
  • Stuffy or runny nose
  • Headache

Other, less serious side effects include:

  • Stomach upset and diarrhea
  • Swelling of the hands or legs if you are also taking Avandia (another kind of diabetes medication)
