Januvia as a Means of Controlling Blood Sugar
Januvia, manufactured by Merck & Co, showed annual sales in 2011 of $3.3 billion
dollars. When combined with its sister drug, Janumet, that number reached $4.7 billion
in 2011. The Januvia diabetic drug—also sold in a combination pill with metformin,
called Janumet—was developed as a means of controlling blood sugar in those
patients with type 2 diabetes when used in combination with diet and exercise. Januvia
works by targeting the natural body system to help regulate glucose by affecting
the pancreatic beta and alpha cells in the pancreas.
Januvia inhibits an enzyme known as DPP-4 (dipeptidyl peptidase-4) which is produced
in the gut following a meal and is responsible for breaking down incretins—hormones
which tell the pancreas to produce more insulin and tell the liver to stop producing
blood sugar. When DPP-4 is inhibited, the amount of incretins rises, causing the
body to produce more insulin and reduce blood-sugar.
Januvia Safety Problems
The medication found in Januvia and Janumet—Sitagliptin—has been linked
to acute pancreatitis, pancreatic cancers and other serious medical issues. Januvia
safety problems surfaced relatively soon after the drug was marketed. Januvia gained
FDA approval in October, 2006, and by February, 2009, had received 88 post-marketing
cases of acute pancreatitis. Of those 88 patients, 19 developed pancreatitis within
30 days of when they began taking Januvia.
A study published in the medical journal, Gastroenterology, in 2011 definitively
linked the use of Januvia with an increased risk of pancreatic cancer and pancreatitis.
Researchers found that Januvia and Janumet patients had six times the increased
risk of pancreatitis and 2.7 times the risk of pancreatic cancer. Results from a
smaller study of organs from diabetic patients treated with Januvia showed an increase
in beta cell mass and pancreatic mass which potentially increases the risks of developing
pancreatic cancer. A more recent study, reported in JAMA Internal Medicine in February,
2013, showed those taking Januvia had approximately double the rate of developing
Symptoms of acute pancreatitis include severe abdominal or back pain accompanied
by nausea, vomiting, tenderness or swelling of the stomach, fever and chills. Researchers
analyzed insurance records and found that patients hospitalized with pancreatitis
were twice as likely to be using Januvia as compared to diabetics who did not develop
pancreatitis. The risk of Januvia pancreatitis is believed to be roughly double
among patients taking the drug and because of this, the FDA flagged pancreatitis
cases among Januvia patients in 2009. Dr. Edwin A. M. Gale, professor of diabetes
medicine in England commented on recent Januvia data published in the British Medical
Journal stating that we should be very worried about the link between Januvia and
pancreatitis as “All forms of pancreatitis, clinical or subclinical predispose
to carcinoma of the pancreas.” Dr. Gale categorized the number of reports
of pancreatitis associated with Januvia and other similar diabetic drugs as reaching
Januvia Pancreatic Cancer
Pancreatic cancer is the fourth leading cause of cancer death for both men and women
and is considered one of the deadliest types of cancer. Nearly 45,000 Americans
will be diagnosed with pancreatic cancer each year and 38,000 will die from it.
The pancreas is a fairly large organ located in front of the spine and behind the
stomach. The function of the pancreas is to make insulin which regulates blood sugar
levels and to make enzymes which are released into the intestines to aid the body
in absorbing fats as well as breaking up proteins and carbohydrates.
Pancreatic cancer is difficult to diagnose, and, unfortunately, it is often diagnosed
late in the course of the disease. Early detection can significantly increase a
person’s chance of survival. Those who have taken Januvia should be on the
alert for any unexplained weight loss, dark urine, back pain, jaundice or clay-colored
stools. Any of these symptoms should be taken very seriously and an appointment
with a physician made immediately to discuss Januvia pancreatic cancer.
Januvia Liver Problems
Although the development of Januvia liver problems is still being investigated among
those using the drug for type-2 diabetes, anecdotal evidence suggests Januvia may
indeed have a negative effect on the liver for certain patients. Specifically, any
individual with a history of non-alcoholic steatohepatitis (a type of liver disease
characterized by inflammation of the liver with concurrent fat accumulation in the
liver) or elevated haptic enzymes, might have a propensity for liver problems with
One case study presented in The Annals of Pharmacotherapy detailed a 58-year old
male with a history of type 2 diabetes and non-alcoholic steatohepatitis who developed
elevated hepatic enzyme levels soon after starting Januvia. In the course of a full
medication review it was determined that Januvia was the most likely cause of the
increased liver enzymes and the drug was discontinued. Tests of the liver enzymes
a month after discontinuing Januvia showed a significant decrease in liver enzymes
and by six months an even greater decrease.
Januvia Thyroid Cancer
Some research indicates that those people with multiple sclerosis, rheumatoid arthritis,
high blood pressure or osteoporosis—in addition to type 2 diabetes—are
at a higher risk of developing thyroid cancer while taking Januvia. A study published
in Gastroenterology in 2011, linked Januvia to at least two cases of thyroid cancer.
While most people who develop thyroid cancer will survive, like pancreatic cancer
it must be detected early. The first symptoms of thyroid cancer are often a lump
in the front, center region of the neck, difficulty breathing, frequent coughing,
neck or throat pain, difficulty swallowing and changes to the voice such as hoarseness.
Treatment can include radiation, chemotherapy and lifelong hormonal supplements
should the thyroid gland require removal.
Januvia Diabetes Medication Side Effects
Other Januvia diabetic drug dangers include severe allergic reactions, persistent
sore throat, red, blistered or peeling skin and a serious, sometimes fatal condition,
known as lactic acidosis. Lactic acidosis causes lactic acid to build up dangerously
in the bloodstream at a faster rate than the body can remove it. Most of the lactic
acidosis cases have occurred in those diabetic patients who also suffer from kidney
or liver problems or heart disease. Risks of lactic acidosis escalate among patients
who drink alcohol or are elderly. Other potential side effects from Januvia include
nausea, appetite loss, vomiting, headache, abdominal pain, sore throat, upset stomach,
diarrhea, upper respiratory infection and runny or stuffy nose.
