`
`
`
`
` WARNING: RISK OF SERIOUS CARDIOVASCULAR AND
`
`
`GASTROINTESTINAL EVENTS
`
`
`
`See full prescribing information for complete boxed warning.
`
`
`
`
`• Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased
`
`
`
`
`risk of serious cardiovascular thrombotic events, including myocardial
`
`
`
`infarction and stroke, which can be fatal. This risk may occur early in
`
`
`
`
`
`treatment and may increase with duration of use. (5.1)
`
`
`• TREXIMET is contraindicated in the setting of coronary artery bypass
`
`
`
`
`
`
`graft (CABG) surgery (4, 5.1)
`
`
`• NSAIDs cause an increased risk of serious gastrointestinal (GI)
`
`
`
`
`adverse events including bleeding, ulceration, and perforation of the
`
`
`
`stomach or intestines, which can be fatal. These events can occur at
`
`
`
`
`any time during use and without warning symptoms. Elderly patients
`
`
`
`and patients with a prior history of peptic ulcer disease and/or GI
`
`
`
`bleeding are at greater risk for serious GI events. (5.2)

`
`------------------------------ DRUG INTERACTIONS------------------------------­
`
`
`
`• Drugs that Interfere with Hemostasis (e.g. warfarin, aspirin, SSRIs/SNRIs):
`
`
`
`
`Monitor patients for bleeding who are concomitantly taking TREXIMET
`
`
`with drugs that interfere with hemostasis. Concomitant use of TREXIMET
`
`
`
`and analgesic doses of aspirin is not generally recommended. (7.1)
`
`
`
`
`
`• ACE Inhibitors and ARBs: Concomitant use with TREXIMET in elderly,
`
`
`
`
`
`
`volume depleted, or those with renal impairment may result in deterioration
`
`
`
`
`
`
`of renal function. In such high risk patients, monitor for signs of worsening
`
`
`
`
`renal function. (7.1)
`
`
`• Diuretics: NSAIDs can reduce natriuretic effect of loop and thiazide
`
`
`
`
`
`diuretics. Monitor patients to assure diuretic efficacy including
`
`
`
`antihypertensive effects. (7.1)
`
`
`• Digoxin: Concomitant use with TREXIMET can increase serum
`
`
`
`
`
`concentration and prolong half-life of digoxin. Monitor serum digoxin
`
`
`levels. (7.1)
`
`
`• Lithium: Increases lithium plasma levels. (7.1)
`
`
`
`
`• Methotrexate: Increases methotrexate plasma levels. (7.1)
`
`
`
`
`-----------------------USE IN SPECIFIC POPULATIONS-----------------------­
` • Infertility: NSAIDs are associated with reversible infertility. Consider

`
` FULL PRESCRIBING INFORMATION
`
`
`WARNING: RISK OF SERIOUS CARDIOVASCULAR AND GASTROINTESTINAL EVENTS
`
`
`Cardiovascular Thrombotic Events
`
`
`
`• Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events,
`
`
`
`
`including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase
`
`
`
`
`with duration of use [see Warnings and Precautions (5.1)].
`
`
`
`• TREXIMET is contraindicated in the setting of coronary artery bypass graft (CABG) surgery [see Contraindications (4)
`
`
`
`
`
`Warnings and Precautions (5.1)].
`
`Gastrointestinal Bleeding, Ulceration, and Perforation
`
`• NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and
`
`
`
`
`perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without
`
`
`warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at
`
`
`
`
`greater risk for serious GI events [see Warnings and Precautions (5.2)].
`
`
`
`
`
`
`INDICATIONS AND USAGE
`1
`
`
`TREXIMET is indicated for the acute treatment of migraine with or without aura in adults and pediatric patients 12 years of age and
`
`
`
`
`
`older.
`
`Limitations of Use
`
`• Use only if a clear diagnosis of migraine headache has been established. If a patient has no response to the first migraine attack
`
`
`
`
`
`
`treated with TREXIMET, reconsider the diagnosis of migraine before TREXIMET is administered to treat any subsequent attacks.
`
`
`
`• TREXIMET is not indicated for the prevention of migraine attacks.
`
`
`
`• Safety and effectiveness of TREXIMET have not been established for cluster headache.
`
`
`
`
`
`
`DOSAGE AND ADMINISTRATION
`2
`
`
`
`Dosage in Adults
`2.1
`
`
`The recommended dosage for adults is 1 tablet of TREXIMET 85/500 mg. TREXIMET 85/500 mg contains a dose of sumatriptan
`
`
`
`
`
`
`
`
`higher than the lowest effective dose. The choice of the dose of sumatriptan, and of the use of a fixed combination such as in
`
`
`
`
`TREXIMET 85/500 mg should be made on an individual basis, weighing the possible benefit of a higher dose of sumatriptan with the
`
`
`
`
`
`
`potential for a greater risk of adverse reactions.
`
`
`The maximum recommended dosage in a 24-hour period is 2 tablets, taken at least 2 hours apart.
`
`
`
`
`
`
`
`The safety of treating an average of more than 5 migraine headaches in adults in a 30-day period has not been established.
`
`
`
`
`
`
`
`
`
`Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and
`
`
`
`Precautions (5)].
`
`
`Dosage in Pediatric Patients 12 to 17 Years of Age
`2.2
`
`
`
`The recommended dosage for pediatric patients 12 to 17 years of age is 1 tablet of TREXIMET 10/60 mg.
`
`
`
`
`
`
`The maximum recommended dosage in a 24-hour period is 1 tablet of TREXIMET 85/500 mg.

`
` WARNINGS AND PRECAUTIONS
`
` Cardiovascular Thrombotic Events
`
`
` 5.1
`
`
`
`
`
` The use of TREXIMET is contraindicated in patients with ischemic or vasospastic coronary artery disease (CAD) and in the setting of
` coronary artery bypass graft (CABG) surgery due to increased risk of serious cardiovascular events with sumatriptan and NSAIDS
`
`
`
`
`
`
` [see Contraindications (4)].
`
`
`
`
`
` Cardiovascular Events with Sumatriptan
`
`
`There have been rare reports of serious cardiac adverse reactions, including acute myocardial infarction, occurring within a few
`
`
`
`hours following administration of sumatriptan. Some of these reactions occurred in patients without known CAD. TREXIMET
`
`
`
`
`may cause coronary artery vasospasm (Prinzmetal’s angina), even in patients without a history of CAD.
`
`
`
`
`Cardiovascular Thrombotic Events with Nonsteroidal Anti-inflammatory Drugs

`
`
`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, including myocardial infarction (MI) and stroke, which can be fatal. Based on
`
`
`
`
`
`
`
`
`available data, it is unclear that the risk for CV thrombotic events is similar for all NSAIDs. The relative increase in serious CV
`
`thrombotic events over baseline conferred by NSAID use appears to be similar in those with and without known CV disease or
`
`
`
`risk factors for CV disease. However, patients with known CV disease or risk factors had a higher absolute incidence of excess
`
`
`
`
`
`
`serious CV thrombotic events, due to their increased baseline rate. Some observational studies found that this increased risk of
`
`
`
`
`
`
`serious CV thrombotic events began as early as the first weeks of treatment. The increase in CV thrombotic risk has been
`
`
`
`observed most consistently at higher doses.
`
`
`
`To minimize the potential risk for an adverse CV event in NSAID-treated patients, use the lowest effective dose for the shortest
`
`
`
`
`
`duration possible. Physicians and patients should remain alert for the development of such events, throughout the entire treatment
`
`course, even in the absence of previous CV symptoms. Patients should be informed about the 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, such as naproxen, increases the risk of serious
`
`
`
`
`
`gastrointestinal (GI) events [see Warnings and Precautions (5.2)].
`
`
`
`
`Status Post Coronary Artery Bypass Graft (CABG) Surgery
`
`
`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. NSAIDs are contraindicated in the setting of
`
`CABG [see Contraindications (4)].
`
`
`
`
`
`
`
`Post-MI Patients
`
`Observational studies conducted in the Danish National Registry have demonstrated that patients treated with NSAIDs in the
`
`post-MI period were at increased risk of reinfarction, CV-related death, and all-cause mortality beginning in the first week of
`
`
`treatment. In this same cohort, the incidence of death in the first year post-MI was 20 per 100 person years in NSAID-treated
`
`
`
`
`
`
`
`patients compared to 12 per 100 person years in non-NSAID exposed patients. Although the absolute rate of death declined
`
`
`
`
`
`somewhat after the first year post-MI, the increased relative risk of death in NSAID users persisted over at least the next four
`
`
`
`
`
`years of follow-up.
`
`
`Perform a cardiovascular evaluation in patients who have multiple cardiovascular risk factors (e.g., increased age, diabetes,
`
`
`hypertension, smoking, obesity, strong family history of CAD) prior to receiving TREXIMET. If there is evidence of CAD or
`
`
`
`
`Reference ID: 4785360
`
`

`

` coronary artery vasospasm, TREXIMET is contraindicated. For patients with multiple cardiovascular risk factors who have a negative
`
`
`
`
` cardiovascular evaluation, consider administering the first dose of TREXIMET in a medically supervised setting and performing an
`
` electrocardiogram (ECG) immediately following administration of TREXIMET. For such patients, consider periodic cardiovascular
`
`
`
` evaluation in intermittent long-term users of TREXIMET.
`
`
`
`
`
`
`Physicians and patients should remain alert for the development of cardiovascular events, even in the absence of previous
`
`
`
`
`
`
`cardiovascular symptoms. Patients should be informed about the signs and/or symptoms of serious cardiovascular events and the steps
`
`to take if they occur.
`
`
`
`
`
`
`Gastrointestinal Bleeding, Ulceration, and Perforation
`5.2
`
`
`
`
`
`
`NSAIDs, including naproxen, a component of TREXIMET, cause serious gastrointestinal 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 1 in 5 patients who develop a
`
`
`
`serious upper gastrointestinal adverse event on NSAID therapy is symptomatic. Upper gastrointestinal ulcers, gross bleeding, or
`
`
`
`
`
`
`perforation caused by NSAIDs appear to occur in approximately 1% of patients treated daily for 3 to 6 months and in about 2% to 4%
`
`
`
`of patients treated for 1 year. However, even short-term therapy is not without risk.
`
`
`
`
`Among 3,302 adult patients with migraine who received TREXIMET in controlled and uncontrolled clinical trials, 1 patient
`
`
`
`experienced a recurrence of gastric ulcer after taking 8 doses over 3 weeks, and 1 patient developed a gastric ulcer after treating an
`
`average of 8 attacks per month over 7 months.
`
`
`
`
`Risk Factors for GI Bleeding, Ulceration, and Perforation
`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 gastrointestinal bleeding compared with patients with neither of these risk factors. Other factors that
`
`
`
`increase the risk for gastrointestinal bleeding in patients treated with NSAIDs include longer duration of NSAID therapy; concomitant
`
`
`use of oral corticosteroids, aspirin, anticoagulants, or selective serotonin reuptake inhibitors (SSRIs); smoking; use of alcohol; older
`
`age; and poor general health status. Most postmarketing reports of fatal gastrointestinal events occurred in elderly or debilitated
`
`
`
`
`
`
`
`
`
`patients, and therefore special care should be taken in treating this population. Additionally, patients with advanced liver disease
`
`
`
`
`
`and/or coagulopathy are at increased risk for GI bleeding.
`
`
`Strategies to Minimize the GI Risks in NSAID-treated patients:
`
`
`• Use the lowest effective dosage for the shortest possible duration.
`
`
`
`• Avoid administration of more than one NSAID at a time.
`
`
`
`
`• Avoid use in patients at higher risk unless benefits are expected to outweigh the increased risk of bleeding. For high risk patients,
`
`
`
`
`as well as those with active GI bleeding, consider alternate therapies other than NSAIDs.
`
`
`• Remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy.
`
`
`
`If a serious GI adverse event is suspected, promptly initiate evaluation and treatment, and discontinue TREXIMET until a serious
`
`
`•
`GI adverse event is ruled out.
`
`
`
`In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, monitor patients more closely for evidence of GI
`
`
`
`
`bleeding [see Drug Interactions (7)].
`
`
`
`•
`
`
`Arrhythmias
`5.3
`
`
`Life-threatening disturbances of cardiac rhythm, including ventricular tachycardia and ventricular fibrillation leading to death, have
`
`
`
`
`been reported within a few hours following the administration of 5-HT1 agonists. Discontinue TREXIMET if these disturbances occur.
`
`
`
`
`Reference ID: 4785360
`
`

`

`TREXIMET is contraindicated in patients with Wolff-Parkinson-White syndrome or arrhythmias associated with other cardiac
`
`
`accessory conduction pathway disorders.
`
`
`
`5.4 Chest, Throat, Neck, and/or Jaw Pain/Tightness/Pressure
`
`
`
`
`
`Sensations of tightness, pain, pressure, and heaviness in the precordium, throat, neck, and jaw commonly occur after treatment with
`
`
`
`
`
`
`sumatriptan and are usually non-cardiac in origin. However, perform a cardiac evaluation if these patients are at high cardiac risk. The
`
`
`
`use of TREXIMET is contraindicated in patients with CAD and those with Prinzmetal’s variant angina.
`
`
`
`5.5 Cerebrovascular Events
`
`
`Cerebral hemorrhage, subarachnoid hemorrhage, and stroke have occurred in patients treated with 5-HT1 agonists, and some have
`
`
`
`
`
`
`resulted in fatalities. In a number of cases, it appears possible that the cerebrovascular events were primary, the 5-HT1 agonist having
`
`
`
`
`
`
`
`
`
`
`
`been administered in the incorrect belief that the symptoms experienced were a consequence of migraine when they were not. Also,
`
`
`
`patients with migraine may be at increased risk of certain cerebrovascular events (e.g., stroke, hemorrhage, TIA). Discontinue
`
`TREXIMET if a cerebrovascular event occurs.
`
`
`Before treating headaches in patients not previously diagnosed as migraineurs, and in migraineurs who present with atypical
`
`
`
`symptoms, exclude other potentially serious neurological conditions. TREXIMET is contraindicated in patients with a history of
`
`
`stroke or TIA [see Contraindications (4)].
`
`
`
`
`5.6 Other Vasospasm Reactions
`
`
`
`Sumatriptan may cause non-coronary vasospastic reactions, such as peripheral vascular ischemia, gastrointestinal vascular ischemia
`
`
`
`
`
`
`
`and infarction (presenting with abdominal pain and bloody diarrhea), splenic infarction, and Raynaud′s syndrome. In patients who
`
`experience symptoms or signs suggestive of non-coronary vasospasm reaction following the use of any 5-HT1 agonist, rule out a
`
`
`
`
`
`
`vasospastic reaction before receiving additional TREXIMET.
`
`
`Reports of transient and permanent blindness and significant partial vision loss have been reported with the use of 5-HT1 agonists.
`
`
`Since visual disorders may be part of a migraine attack, a causal relationship between these events and the use of 5-HT1 agonists have
`
`
`
`
`
`
`
`not been clearly established.
`
`
`
`5.7 Hepatotoxicity
`
`
`
`Borderline elevations of 1 or more liver tests may occur in up to 15% of patients who take NSAIDs including naproxen, a component
`
`
`of TREXIMET. Hepatic abnormalities may be the result of hypersensitivity rather than direct toxicity. These abnormalities may
`
`
`progress, may remain essentially unchanged, or may be transient with continued therapy. Notable (3 times the upper limit of normal)
`
`
`
`
`
`elevations of SGPT (ALT) or SGOT (AST) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In
`
`addition, rare, sometimes fatal cases of severe hepatic injury, including jaundice and fatal fulminant hepatitis, liver necrosis, and
`
`
`hepatic failure have been reported with NSAIDs.
`
`TREXIMET is contraindicated in patients with severe hepatic impairment [see Use in Specific Populations (8.7), Clinical
`
`
`Pharmacology (12.3)]. A patient with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has
`
`occurred, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with TREXIMET.
`
`
`
`
`TREXIMET should be discontinued if clinical signs and symptoms consistent with liver disease develop, if systemic manifestations
`
`
`occur (e.g., eosinophilia, rash), or if abnormal liver tests persist or worsen.
`
`
`Inform patients of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, diarrhea, pruritus, jaundice, right
`
`
`
`upper quadrant tenderness, and "flulike" symptoms). If clinical signs and symptoms consistent with liver disease develop, or if
`
`Reference ID: 4785360
`
`

`

`systemic manifestations occur (e.g., eosinophilia, rash, etc.), discontinue TREXIMET immediately, and perform a clinical evaluation
`
`
`
`
`of the patient.
`
`
`
`5.8 Hypertension
`
`
`Significant elevation in blood pressure, including hypertensive crisis with acute impairment of organ systems, has been reported on
`rare occasions in patients treated with 5-HT1 agonists, including sumatriptan, a component of TREXIMET. This occurrence has
`
`
`
`
`
`
`
`
`included patients without a history of hypertension.
`
`
`
`
`
`
`
`NSAIDs, including naproxen, a component of TREXIMET, can also lead to onset of new hypertension or worsening of preexisting
`
`
`
`
`
`
`hypertension, either of which may contribute to the increased incidence of cardiovascular events. Patients taking angiotensin
`
`
`
`
`
`
`
`converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), beta-blockers, thiazide diuretics, or loop diuretics may
`
`
`
`have impaired response to these therapies when taking NSAIDs [see Drug Interactions (7)].
`
`
`
`Monitor blood pressure in patients treated with TREXIMET. TREXIMET is contraindicated in patients with uncontrolled
`
`
`hypertension [see Contraindications (4)].
`
`
`
`5.9 Heart Failure and Edema
`The Coxib and traditional NSAID Trialists’ Collaboration meta-analysis of randomized controlled trials demonstrated an
`
`
`
`
`approximately two-fold increase in hospitalizations for heart failure in COX-2 selective-treated patients and nonselective NSAID-
`
`treated patients compared to placebo-treated patients. In a Danish National Registry study of patients with heart failure, NSAID use
`
`
`
`
`
`increased the risk of MI, hospitalization for heart failure, and death.
`
`
`
`Additionally, fluid retention and edema have been observed in some patients treated with NSAIDs. Use of naproxen may blunt the CV
`
`
`
`
`
`
`effects of several therapeutic agents used to treat these medical conditions (e.g., diuretics, ACE inhibitors, or angiotensin receptor
`
`
`
`blockers [ARBs]) [see Drug Interactions (7)].
`
`
`
`
`Avoid the use of TREXIMET in patients with severe heart failure unless the benefits are expected to
