About JANUVIA^®(sitagliptin) 25 mg, 50 mg, and 100 mg tablets

JANUVIA is indicated, as an adjunct to diet and exercise, to improve glycemic
control in adults with type 2 diabetes mellitus. JANUVIA should not be used in
patients with type 1 diabetes or for the treatment of diabetic ketoacidosis.
JANUVIA has not been studied in patients with a history of pancreatitis. It is
unknown whether patients with a history of pancreatitis are at increased risk
of developing pancreatitis while taking JANUVIA.

Selected Important Risk Information About JANUVIA

JANUVIA is contraindicated in patients with a history of a serious
hypersensitivity reaction to sitagliptin, such as anaphylaxis or angioedema.

There have been postmarketing reports of acute pancreatitis, including fatal
and nonfatal hemorrhagic or necrotizing pancreatitis, in patients taking
JANUVIA. After initiating JANUVIA, observe patients carefully for signs and
symptoms of pancreatitis. If pancreatitis is suspected, promptly discontinue
JANUVIA and initiate appropriate management. It is unknown whether patients
with a history of pancreatitis are at increased risk of developing
pancreatitis while taking JANUVIA.

Assessment of renal function is recommended prior to initiating JANUVIA^®
(sitagliptin) and periodically thereafter. A dosage adjustment is recommended
in patients with moderate or severe renal insufficiency and in patients with
end-stage renal disease requiring hemodialysis or peritoneal dialysis. Caution
should be used to ensure that the correct dose of JANUVIA is prescribed.

There have been postmarketing reports of worsening renal function, including
acute renal failure, sometimes requiring dialysis. A subset of these reports
involved patients with renal insufficiency, some of whom were prescribed
inappropriate doses of sitagliptin.

When JANUVIA was used in combination with a sulfonylurea or insulin,
medications known to cause hypoglycemia, the incidence of hypoglycemia was
increased over that of placebo. Therefore, a lower dose of sulfonylurea or
insulin may be required to reduce the risk of hypoglycemia.

The incidence (and rate) of hypoglycemia based on all reports of symptomatic
hypoglycemia were: 12.2 percent (0.59 episodes per patient-year) for JANUVIA
100 mg in combination with glimepiride (with or without metformin), 1.8
percent (0.24 episodes per patient-year) for placebo in combination with
glimepiride (with or without metformin), 15.5 percent (1.06 episodes per
patient-year) for JANUVIA 100 mg in combination with insulin (with or without
metformin), and 7.8 percent (0.51 episodes per patient-year) for placebo in
combination with insulin (with or without metformin).

There have been postmarketing reports of serious hypersensitivity reactions in
patients treated with JANUVIA, such as anaphylaxis, angioedema, and
exfoliative skin conditions including Stevens-Johnson syndrome. Onset of these
reactions occurred within the first 3 months after initiation of treatment
with JANUVIA, with some reports occurring after the first dose. If a
hypersensitivity reaction is suspected, discontinue JANUVIA, assess for other
potential causes for the event, and institute alternative treatment for

Angioedema has also been reported with other dipeptidyl peptidase-4 (DPP-4)
inhibitors. Use caution in a patient with a history of angioedema with another
DPP-4 inhibitor because it is unknown whether such patients will be
predisposed to angioedema with JANUVIA.

There have been no clinical studies establishing conclusive evidence of
macrovascular risk reduction with JANUVIA or with any other antidiabetic drug.

In clinical studies, the adverse reactions reported, regardless of
investigator assessment of causality, in greater than or equal to 5 percent of
patients treated with JANUVIA as monotherapy and in combination therapy and
more commonly than in patients treated with placebo, were upper respiratory
tract infection, nasopharyngitis, and headache.

No overall differences in safety or effectiveness were observed between
subjects 65 years and over and younger subjects. While this and other reported
clinical experience have not been identified differences in responses between
the elderly and younger patients, greater sensitivity of some older
individuals cannot be ruled out.

This drug is known to be substantially excreted by the kidney. Because elderly
patients are more likely to have decreased renal function, care should be
taken in dose selection in the elderly, and it may be useful to assess renal
function in these patients prior to initiating dosing and periodically
