METFORMIN HYDROCHLORIDE
WARNING: LACTIC ACIDOSIS
Postmarketing cases of metformin-associated lactic acidosis have
resulted in
death, hypothermia, hypotension, and resistant bradyarrhythmias. The
onset of
metformin-associated lactic acidosis is often subtle, accompanied only
by
nonspecific symptoms such as malaise, myalgias, respiratory distress,
somnolence, and abdominal pain. Metformin-associated lactic acidosis
was
characterized by elevated blood lactate levels (>5 mmol/Liter), anion
gap acidosis
(without evidence of ketonuria or ketonemia), an increased
lactate/pyruvate ratio;
and metformin plasma levels generally >5 mcg/mL [SEE WARNINGS AND
PRECAUTIONS (5.1)].
Risk factors for metformin-associated lactic acidosis include renal
impairment,
concomitant use of certain drugs (e.g. carbonic anhydrase inhibitors
such as
topiramate), age 65 years old or greater, having a radiological study
with contrast,
surgery and other procedures, hypoxic states (e.g., acute congestive
heart
failure), excessive alcohol intake, and hepatic impairment.
Steps to reduce the risk of and manage metformin-associated lactic
acidosis in
these high risk groups are provided [SEE DOSAGE AND ADMINISTRATION
(2.3),
CONTRAINDICATIONS (4), WARNINGS AND PRECAUTIONS (5.1)].
If metformin-associated lactic acidosis is suspected, immediately
discontinue
metformin and institute general supportive measures in a hospital
setting. Prompt
hemodialysis is recommended [SEE WARNINGS AND PRECAUTIONS (5.1)].
Metformin Hydrochloride Tablets are indicated as an adjunct to diet
and exercise to
improve glycemic control in adults and pediatric patients 10 years of
age and older with
type 2 diabetes mellitus.
