WARNINGS
Cardiovascular EffectsCardiovascular Thrombotic Events
Clinical trials of several COX-2 selective and nonselective
NSAIDs of up to three years duration have shown an increased risk of serious
cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which
can be fatal. All NSAIDs, both COX-2 selective and nonselective, may have a
similar risk. Patients with known CV disease or risk factors for CV disease may
be at greater risk. To minimize the potential risk for an adverse CV event in
patients treated with an NSAID, the lowest effective dose should be used for the
shortest duration possible. Physicians and patients should remain alert for the
development of such events, even in the absence of previous CV symptoms.
Patients should be informed about the signs and/or symptoms of serious CV events
and the steps to take if they occur.
There is no consistent evidence that concurrent use of aspirin mitigates the
increased risk of serious CV thrombotic events associated with NSAID use. The
concurrent use of aspirin and an NSAID does increase the risk of serious GI
events (see WARNINGS, Gastrointestinal (GI) Effects - Risk of GI
Ulceration, Bleeding, and Perforation).
Two large, controlled, clinical trials of a COX-2 selective NSAID for the
treatment of pain in the first 10-14 days following CABG surgery found an
increased incidence of myocardial infarction and stroke (see CONTRAINDICATIONS).
Hypertension
NSAIDs, including meloxicam can lead to onset of new
hypertension or worsening of pre-existing hypertension, either of which may
contribute to the increased incidence of CV events. Patients taking thiazides or
loop diuretics may have impaired response to these therapies when taking NSAIDs.
NSAIDs, including meloxicam should be used with caution in patients with
hypertension. Blood pressure (BP) should be monitored closely during the
initiation of NSAID treatment and throughout the course of therapy.
Congestive Heart Failure and Edema
Fluid retention and edema have been observed in some
patients taking NSAIDs. Meloxicam should be used with caution in patients with
fluid retention, hypertension, or heart failure.
Gastrointestinal (GI) Effects - Risk of GI Ulceration,
Bleeding, and Perforation
NSAIDs, including meloxicam can cause serious
gastrointestinal (GI) adverse events including inflammation, bleeding,
ulceration, and perforation of the stomach, small intestine, or large intestine,
which can be fatal. These serious adverse events can occur at any time, with or
without warning symptoms, in patients treated with NSAIDs. Only one in five
patients, who develop a serious upper GI adverse event on NSAID therapy, is
symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs,
occur in approximately 1% of patients treated for 3-6 months, and in about 2-4%
of patients treated for one year. These trends continue with longer duration of
use, increasing the likelihood of developing a serious GI event at some time
during the course of therapy. However, even short-term therapy is not without
risk.
NSAIDs should be prescribed with extreme caution in those with a prior
history of ulcer disease or gastrointestinal bleeding. Patients with a prior history of peptic ulcer disease and/or gastrointestinal
bleeding who use NSAIDs have a greater than 10-fold increased risk for
developing a GI bleed compared to patients with neither of these risk factors.
Other factors that increase the risk for GI bleeding in patients treated with
NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer
duration of NSAID therapy, smoking, use of alcohol, older age, and poor general
health status. Most spontaneous reports of fatal GI events are in elderly or
debilitated patients and therefore, special care should be taken in treating
this population.
To minimize the potential risk for an adverse GI event in patients treated
with an NSAID, the lowest effective dose should be used for the shortest
possible duration. Patients and physicians should remain alert for signs and
symptoms of GI ulceration and bleeding during NSAID therapy and promptly
initiate additional evaluation and treatment if a serious GI adverse event is
suspected. This should include discontinuation of the NSAID until a serious GI
adverse event is ruled out. For high-risk patients, alternate therapies that do
not involve NSAIDs should be considered.
Renal Effects
Long-term administration of NSAIDs including meloxicam can
result in renal papillary necrosis, renal insufficiency, acute renal failure,
and other renal injury. Renal toxicity has also been seen in patients in whom
renal prostaglandins have a compensatory role in the maintenance of renal
perfusion. In these patients, administration of a nonsteroidal anti-inflammatory
drug may cause a dose-dependent reduction in prostaglandin formation and,
secondarily, in renal blood flow, which may precipitate overt renal
decompensation. Patients at greatest risk of this reaction are those with
impaired renal function, heart failure, liver dysfunction, those taking
diuretics and ACE inhibitors, angiotensin II receptor antagonists, and the
elderly. Discontinuation of NSAID therapy is usually followed by recovery to the
pretreatment state.
Advanced Renal Disease
No information is available from controlled clinical studies
regarding the use of meloxicam in patients with advanced renal disease.
Therefore, treatment with meloxicam is not recommended in these patients with
advanced renal disease. If meloxicam therapy must be initiated, close monitoring
of the patient's renal function is advisable.
Anaphylactoid Reactions
As with other NSAIDS, anaphylactoid reactions have occurred
in patients without known prior exposure to meloxicam. Meloxicam should not be
given to patients with the aspirin triad. This symptom complex typically occurs
in asthmatic patients who experience rhinitis with or without nasal polyps, or
who exhibit severe, potentially fatal bronchospasm after taking aspirin or other
NSAIDs (see CONTRAINDICATIONS and
PRECAUTIONS, Pre-existing Asthma). Emergency help should be sought in
cases where an anaphylactoid reaction occurs.
Skin Reactions
NSAIDs, including meloxicam can cause serious skin adverse
events such as exfoliative dermatitis, Stevens - Johnson syndrome (SJS), and
toxic epidermal necrolysis (TEN), which can be fatal. These serious events may
occur without warning. Patients should be informed about the signs and symptoms
of serious skin manifestations and use of the drug should be discontinued at the
first appearance of skin rash or any other sign of hypersensitivity.
Pregnancy
In late pregnancy, as with other NSAIDs, meloxicam should be
avoided because it may cause premature closure of the ductus arteriosus.
