Uses
1 INDICATIONS AND USAGE TREXIMET is indicated for the acute treatment of migraine with or without aura in adults and pediatric patients 12 years of age and older. TREXIMET is a combination of sumatriptan, a serotonin (5-HT) 1b/1d receptor agonist (triptan), and naproxen sodium, a non-steroidal anti-inflammatory drug, indicated for the acute treatment of migraine with or without aura in adults and pediatric patients 12 years of age and older. ( 1 ) Limitations of Use: Use only if a clear diagnosis of migraine headache has been established. ( 1 ) Not indicated for the prophylactic therapy of migraine attacks. ( 1 ) Not indicated for the treatment of cluster headache. ( 1 ) 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
Adults Recommended dosage: 1 tablet of 85/500 mg. ( 2.1 ) Maximum dosage in a 24-hour period: 2 tablets of 85/500 mg; separate doses by at least 2 hours. ( 2.1 ) Pediatric Patients 12 to 17 years of Age Recommended dosage: 1 tablet of 10/60 mg. ( 2.2 ) Maximum dosage in a 24-hour period: 1 tablet of 85/500 mg. Mild to Moderate Hepatic Impairment Recommended dosage: 1 tablet of 10/60 mg. ( 2.3 , 8.7 ) 2.1 Dosage in Adults 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) ] . 2.2 Dosage in Pediatric Patients 12 to 17 Years of Age 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. The safety of treating an average of more than 2 migraine headaches in pediatric patients 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) ] . 2.3 Dosing in Patients with Hepatic Impairment TREXIMET is contraindicated in patients with severe hepatic impairment [see Contraindications (4) , Use in Specific Populations (8.7) , Clinical Pharmacology (12.3) ] . In patients with mild to moderate hepatic impairment, the recommended dosage in a 24-hour period is 1 tablet of TREXIMET 10/60 mg [see Use in Specific Populations (8.7) , Clinical Pharmacology (12.3) ] .

Discontinue if abnormal liver tests persist or worsen or if clinical signs and symptoms of liver disease develop. ( 5.7 ) Hypertension: Patients taking some antihypertensive medications may have impaired response to these therapies when taking NSAIDs. Monitor blood pressure. ( 5.8 ) Heart Failure and Edema: Avoid use of TREXIMET in patients with severe heart failure unless benefits are expected to outweigh risk of worsening heart failure. ( 5.9 ) Medication Overuse Headache: Detoxification may be necessary. ( 5.10 ) Serotonin Syndrome: Discontinue TREXIMET if occurs. ( 5.11 ) Renal Toxicity and Hyperkalemia: Monitor renal function in patients with renal or hepatic impairment, heart failure, dehydration, or hypovolemia. Avoid use of TREXIMET in patients with advanced renal disease. ( 5.12 ) Anaphylactic Reactions: TREXIMET should not be given to patients with the aspirin triad.

( 5.14 ) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): Discontinue and evaluate clinically. ( 5.15 ) Fetal Toxicity: Limit use of NSAIDs, including TREXIMET, between about 20 to 30 weeks in pregnancy due to the risk of oligohydramnios/fetal renal dysfunction. Avoid use of NSAIDs in women at about 30 weeks gestation and later in pregnancy due to the risks of oligohydramnios/fetal renal dysfunction and premature closure of the fetal ductus arteriosus. ( 5.16 , 8.1 ) Hematologic Toxicity: Monitor hemoglobin or hematocrit in patients with any signs or symptoms of anemia. ( 5.17 ) Exacerbation of Asthma Related to Aspirin Sensitivity: TREXIMET is contraindicated in patients with aspirin-sensitive asthma. Monitor patients with preexisting asthma (without aspirin sensitivity). ( 5.18 ) 5.1 Cardiovascular Thrombotic Events 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.

Adults The adverse reactions reported below are specific to the clinical trials with TREXIMET 85/500 mg. See also the full prescribing information for naproxen and sumatriptan products. Table 1 lists adverse reactions that occurred in 2 placebo-controlled clinical trials (Study 1 and 2) in adult patients who received 1 dose of study drug. Only adverse reactions that occurred at a frequency of 2% or more in any group treated with TREXIMET 85/500 mg and that occurred at a frequency greater than the placebo group are included in Table 1.

There were insufficient data to assess the impact of race on the incidence of adverse reactions. Pediatric Patients 12 to 17 Years of Age In a placebo controlled clinical trial that evaluated pediatric patients 12 to 17 years of age who received 1 dose of TREXIMET 10/60 mg, 30/180 mg, or 85/500 mg, adverse reactions occurred in 13% of patients who received 10/60 mg, 9% of patients who received 30/180 mg, 13% who received 85/500 mg, and 8% who received placebo. No patients who received TREXIMET experienced adverse reactions leading to withdrawal from the trial. The incidence of adverse reactions in pediatric patients 12 to 17 years of age was comparable across all 3 doses compared with placebo. Table 2 lists adverse reactions that occurred in a placebo-controlled trial in pediatric patients 12 to 17 years of age at a frequency of 2% or more with TREXIMET and were more frequent than the placebo group.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Skin and Appendages: exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), and fixed drug eruption (FDE) [see Warnings and Precautions (5.14) ].
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 ) 7.1 Clinically Significant Drug Interactions with TREXIMET See Table 3 for clinically significant drug interactions with NSAIDs or Sumatriptan. Table 3. Clinically Significant Drug Interactions with Naproxen or Sumatriptan Ergot-Containing Drugs Clinical Impact: Ergot-containing drugs have been reported to cause prolonged vasospastic reactions. Intervention: Because these effects may be additive, coadministration of TREXIMET and ergotamine-containing or ergot-type medications (like dihydroergotamine or methysergide) within 24 hours of each other is contraindicated. Monoamine Oxidase-A Inhibitors Clinical Impact: MAO-A inhibitors increase systemic exposure of orally administered sumatriptan by 7-fold. Intervention: The use of TREXIMET in patients receiving MAO-A inhibitors is contraindicated. Other 5-HT 1 Agonists Clinical Impact: 5-HT 1 agonist drugs can cause vasospastic effects. Intervention: Because these effects may be additive, coadministration of TREXIMET and other 5 HT 1 agonists (e.g., triptans) within 24 hours of each other is contraindicated. Drugs That Interfere with Hemostasis Clinical Impact: Naproxen and anticoagulants such as warfarin have a synergistic effect on bleeding. The concomitant use of naproxen and anticoagulants have an increased risk of serious bleeding compared to the use of either drug alone. Serotonin release by platelets plays an important role in hemostasis. Case-control and cohort epidemiological studies showed that concomitant use of drugs that interfere with serotonin reuptake and an NSAID may potentiate the risk of bleeding more than an NSAID alone. Intervention: Monitor patients with concomitant use of TREXIMET with anticoagulants (e.g., warfarin), antiplatelet agents (e.g., aspirin), selective serotonin reuptake inhibitors (SSRIs), and serotonin norepinephrine reuptake inhibitors (SNRIs) for signs of bleeding [see Warnings and Precautions (5.17) ] . Aspirin Clinical Impact: A pharmacodynamic (PD) study has demonstrated an interaction in which lower dose naproxen (220mg/day or 220mg twice daily) interfered with the antiplatelet effect of low-dose immediate-release aspirin, with the interaction most marked during the washout period of naproxen [see Clinical Pharmacology (12.2) ] . There is reason to expect that the interaction would be present with prescription doses of naproxen or with enteric-coated low-dose aspirin; however, the peak interference with aspirin function may be later than observed in the PD study due to the longer washout period. Controlled clinical studies showed that the concomitant use of NSAIDs and analgesic doses of aspirin does not produce any greater therapeutic effect than the use of NSAIDs alone. In a clinical study, the concomitant use of an NSAID and aspirin was associated with a significantly increased incidence of GI adverse reactions as compared to use of the NSAID alone [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.3) ] . Intervention: Because there may be an increased risk of cardiovascular events following discontinuation of naproxen due to the interference with the antiplatelet effect of aspirin during the washout period, for patients taking low-dose aspirin for cardioprotection who require intermittent analgesics, consider use of an NSAID that does not interfere with the antiplatelet effect of aspirin, or non-NSAID analgesics where appropriate. Concomitant use of TREXIMET and analgesic doses of aspirin is not generally recommended because of the increased risk of bleeding [see Warnings and Precautions (5.17) ] . Selective Serotonin Reuptake Inhibitors/Serotonin Norepinephrine Reuptake Inhibitors and Serotonin Syndrome Clinical Impact: Cases of serotonin syndrome have been reported during coadministration of triptans and SSRIs, SNRIs, TCAs, and MAO inhibitors [see Warnings and Precautions (5.11) ] . Intervention: Discontinue TREXIMET if serotonin syndrome is suspected. ACE Inhibitors, Angiotensin Receptor Blockers, and Beta-blockers Clinical Impact: NSAIDs may diminish the antihypertensive effect of angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), or beta-blockers (including propranolol). In patients who are elderly, volume-depleted (including those on diuretic therapy), or have renal impairment, co-administration of an NSAID with ACE inhibitors or ARBs may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Intervention: During concomitant use of TREXIMET and ACE-inhibitors, ARBs, or beta-blockers, monitor blood pressure to ensure that the desired blood pressure is obtained [see Warnings and Precautions (5.8) ] . During concomitant use of TREXIMET and ACE-inhibitors or ARBs in patients who are elderly, volume-depleted, or have impaired renal function, monitor for signs of worsening renal function [see Warnings and Precautions (5.8) ].
Use in specific populations
Infertility: NSAIDs are associated with reversible infertility. Consider withdrawal of TREXIMET in women who have difficulties conceiving ( 8.3 ) 8.1 Pregnancy Risk Summary Use of NSAIDs, including TREXIMET, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. Because of these risks, limit dose and duration of TREXIMET use between about 20 and 30 weeks of gestation, and avoid TREXIMET use at about 30 weeks of gestation and later in pregnancy ( see Clinical Considerations , Data ). Premature Closure of Fetal Ductus Arteriosus Use of NSAIDs, including TREXIMET, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Oligohydramnios/Neonatal Renal Impairment Use of NSAIDs at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. Data from observational studies regarding other potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive. Data from a prospective pregnancy exposure registry and epidemiological studies of pregnant women have not detected an increased frequency of birth defects or a consistent pattern of birth defects among women exposed to sumatriptan compared with the general population ( see Human Data ). In animal studies, administration of sumatriptan and naproxen, alone or in combination, during pregnancy resulted in developmental toxicity (increased incidences of fetal malformations, embryofetal and pup mortality, decreased embryofetal growth) at clinically relevant doses ( see Animal Data ). Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. In animal studies, administration of prostaglandin synthesis inhibitors such as naproxen sodium resulted in increased pre- and post-implantation loss. Prostaglandins also have been shown to have an important role in fetal kidney development. In published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The reported rate of major birth defects among deliveries to women with migraine ranged from 2.2% to 2.9% and the reported rate of miscarriage was 17%, which were similar to rates reported in women without migraine. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Several studies have suggested that women with migraine may be at increased risk of preeclampsia and gestational hypertension during pregnancy. Fetal/Neonatal Adverse Reactions Premature Closure of Fetal Ductus Arteriosus: Avoid use of NSAIDs in women at about 30 weeks gestation and later in pregnancy, because NSAIDs, including TREXIMET, can cause premature closure of the fetal ductus arteriosus ( see Data ). Oligohydramnios/Neonatal Renal Impairment: If an NSAID is necessary at about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective dose and shortest duration possible. If TREXIMET treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. If oligohydramnios occurs, discontinue TREXIMET and follow up according to clinical practice ( see Data ). Labor or Delivery There are no studies on the effects of naproxen tablets during labor or delivery. In animal studies, NSAIDS, including naproxen, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth. Data Human Data There is some evidence to suggest that when inhibitors of prostaglandin synthesis are used to delay preterm labor, there is an increased risk of neonatal complications such as necrotizing enterocolitis, patent ductus arteriosus, and intracranial hemorrhage. Naproxen treatment given in late pregnancy to delay parturition has been associated with persistent pulmonary hypertension, renal dysfunction, and abnormal prostaglandin E levels in preterm infants. The Sumatriptan/Naratriptan/Treximet (sumatriptan and naproxen sodium) Pregnancy Registry, a population-based international prospective study, collected data for sumatriptan from January 1996 to September 2012. The Registry included only 6 pregnancy exposures to TREXIMET, with no major birth defects reported. The Registry documented outcomes of 626 infants and fetuses exposed to sumatriptan during pregnancy (528 with earliest exposure during the first trimester, 78 during the second trimester, 16 during the third trimester, and 4 unknown). The occurrence of major birth defects (excluding fetal deaths and induced abortions without reported defects and all spontaneous pregnancy losses) during first-trimester exposure to sumatriptan was 4.2% (20/478 [95% CI: 2.6% to 6.5%]) and during any trimester of exposure was 4.2% (24/576 [95% CI: 2.7% to 6.2%]). The sample size in this study had 80% power to detect at least a 1.73- to 1.91-fold increase in the rate of major malformations. The number of exposed pregnancy outcomes accumulated during the registry was insufficient to support definitive conclusions about overall malformation risk or to support making comparisons of the frequencies of specific birth defects. Of the 20 infants with reported birth defects after exposure to sumatriptan in the first trimester, 4 infants had ventricular septal defects, including one infant who was exposed to both sumatriptan and naratriptan, and 3 infants had pyloric stenosis. No other birth defect was reported for more than 2 infants in this group.

The Registry included only 6 pregnancy exposures to TREXIMET, with no major birth defects reported. The Registry documented outcomes of 626 infants and fetuses exposed to sumatriptan during pregnancy (528 with earliest exposure during the first trimester, 78 during the second trimester, 16 during the third trimester, and 4 unknown). The occurrence of major birth defects (excluding fetal deaths and induced abortions without reported defects and all spontaneous pregnancy losses) during first-trimester exposure to sumatriptan was 4.2% (20/478 [95% CI: 2.6% to 6.5%]) and during any trimester of exposure was 4.2% (24/576 [95% CI: 2.7% to 6.2%]). The sample size in this study had 80% power to detect at least a 1.73- to 1.91-fold increase in the rate of major malformations. The number of exposed pregnancy outcomes accumulated during the registry was insufficient to support definitive conclusions about overall malformation risk or to support making comparisons of the frequencies of specific birth defects. Of the 20 infants with reported birth defects after exposure to sumatriptan in the first trimester, 4 infants had ventricular septal defects, including one infant who was exposed to both sumatriptan and naratriptan, and 3 infants had pyloric stenosis. No other birth defect was reported for more than 2 infants in this group.
Pediatric use
8.4 Pediatric Use Safety and effectiveness of TREXIMET in pediatric patients under 12 years of age have not been established. The safety and efficacy of TREXIMET for the acute treatment of migraine in pediatric patients 12 to 17 years of age was established in a double-blind, placebo-controlled trial [see Adverse Reactions (6.1) and Clinical Studies (14.2) ] .
Geriatric use
8.5 Geriatric Use Elderly patients, compared to younger patients, are at greater risk for NSAID-associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions. TREXIMET is not recommended for use in elderly patients who have decreased renal function, higher risk for unrecognized CAD, and increases in blood pressure that may be more pronounced in the elderly [see Warnings and Precautions (5.1 , 5.2 , 5.3 , 5.8 , 5.12) and Clinical Pharmacology (12.3) ] . A cardiovascular evaluation is recommended for geriatric patients who have other cardiovascular risk factors (e.g., diabetes, hypertension, smoking, obesity, strong family history of CAD) prior to receiving TREXIMET [see Warnings and Precautions (5.1) ] .
Overdosage
Patients (N = 670) have received single oral doses of 140 to 300 mg of sumatriptan without significant adverse effects. Volunteers (N = 174) have received single oral doses of 140 to 400 mg without serious adverse events. Overdose of sumatriptan in animals has been fatal and has been heralded by convulsions, tremor, paralysis, inactivity, ptosis, erythema of the extremities, abnormal respiration, cyanosis, ataxia, mydriasis, salivation, and lacrimation. Symptoms following acute NSAID overdosages have been typically limited to lethargy, drowsiness, nausea, vomiting and epigastric pain. Gastrointestinal bleeding has occurred. Hypertension, acute renal failure, respiratory depression, and coma have occurred, but were rare [see Warnings and Precautions (5.1 , 5.2) ] . Manage patients with symptomatic and supportive care following an NSAID overdosage. There are no specific antidotes. Consider emesis and/or activated charcoal (60 to 100 grams in adults, 1 to 2 grams per kg of body weight in pediatric patients) and/or osmotic cathartic in symptomatic patients seen within four hours of ingestion or in patients with a large overdosage (5 to 10 times the recommended dosage). Hemodialysis does not decrease the plasma concentration of naproxen because of the high degree of its protein binding. It is unknown what effect hemodialysis or peritoneal dialysis has on the serum concentrations of sumatriptan. Forced diuresis, alkalinization of urine, hemodialysis, or hemoperfusion may not be useful due to high protein binding. For additional information about overdosage treatment contact a poison control center (1-800-222-1222).
Description
11 DESCRIPTION TREXIMET contains sumatriptan (as the succinate), a selective 5-hydroxytryptamine 1 (5-HT 1 ) receptor subtype agonist, and naproxen sodium, a member of the arylacetic acid group of NSAIDs. Sumatriptan succinate is chemically designated as 3-[2-(dimethylamino)ethyl]-N-methyl-indole-5-methanesulfonamide succinate (1:1), and it has the following structure: The empirical formula is C 14 H 21 N 3 O 2 S∙C 4 H 6 O 4 , representing a molecular weight of 413.5. Sumatriptan succinate is a white to off-white powder that is readily soluble in water and in saline.

Chemical Structure Chemical Structure
Mechanism of action
12.1 Mechanism of Action TREXIMET contains sumatriptan and naproxen. Sumatriptan binds with high affinity to cloned 5-HT 1B / 1D receptors. Sumatriptan presumably exerts its therapeutic effects in the treatment of migraine headache through agonist effects at the 5-HT 1B/1D receptors on intracranial blood vessels and sensory nerves of the trigeminal system, which result in cranial vessel constriction and inhibition of neuropeptide release. TREXIMET has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of TREXIMET, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Naproxen is a potent inhibitor of prostaglandin synthesis in vitro . Naproxen concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation. Because naproxen is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues.

Patient information
Advise the patient to read the FDA-approved patient labeling (Medication Guide) that accompanies each prescription dispensed. Inform patients, families, or their caregivers of the following information before initiating therapy with TREXIMET and periodically during the course of ongoing therapy. Cardiovascular Thrombotic Events, Prinzmetal's Angina, Other Vasospasm-Related Events, Arrhythmias and Cerebrovascular Events Advise patients to be alert for the symptoms of cardiovascular thrombotic effects such as myocardial infarction or stroke, which may result in hospitalization and even death. Although serious cardiovascular events can occur without warning symptoms, patients should be alert for signs and symptoms of chest pain, shortness of breath, weakness, irregular heartbeat, significant rise in blood pressure, weakness and slurring of speech, and should be advised to report any of these symptoms to their health care provider immediately. Apprise patients of the importance of this follow-up [see Warnings and Precautions (5.1 , 5.3 , 5.5 , 5.6 , 5.8) ] . Gastrointestinal Bleeding, Ulceration, and Perforation Advise patients to report symptoms of ulcerations and bleeding, including epigastric pain, dyspepsia, melena, and hematemesis to their health care provider. In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, inform patients of the increased risk for and the signs and symptoms of GI bleeding [see Warnings and Precautions (5.2) ] . Hepatotoxicity Inform patients of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, diarrhea, jaundice, right upper quadrant tenderness, and "flu-like" symptoms). If these occur, instruct patients to stop TREXIMET and seek immediate medical therapy [see Warnings and Precautions (5.7) ] . Anaphylactic Reactions Inform patients that anaphylactic reactions have occurred in patients receiving the components of TREXIMET. Such reactions can be life-threatening or fatal. In general, anaphylactic reactions to drugs are more likely to occur in individuals with a history of sensitivity to multiple allergens. Inform patients of the signs of an anaphylactic reaction (e.g., difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help [see Contraindications (4) , Warnings and Precautions (5.13) ]. Serious Skin Reactions, including DRESS Inform patients that TREXIMET, like other NSAID-containing products, may increase the risk of serious skin side effects such as exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis, and DRESS, which may result in hospitalizations and even death. Although serious skin reactions may occur without warning, patients should be alert for the signs and symptoms of skin rash and blisters, fever, or other signs of hypersensitivity such as itching and should ask for medical advice when observing any indicative signs or symptoms. Advise patients to stop taking TREXIMET immediately if they develop any type of rash or fever and contact their healthcare providers as soon as possible [see Warnings and Precautions (5.14 , 5.15) ] . Fetal Toxicity Inform pregnant women to avoid use of TREXIMET and other NSAIDs starting at 30 weeks gestation because of the risk of the premature closing of the fetal ductus arteriosus. If treatment with TREXIMET is needed for a pregnant woman between about 20 to 30 weeks gestation, advise her that she may need to be monitored for oligohydramnios, if treatment continues for longer than 48 hours [see Warnings and Precautions (5.16) , Use in Specific Populations (8.1) ] . Lactation Advise patients to notify their healthcare provider if they are breastfeeding or plan to breastfeed [see Use in Specific Populations (8.2) ] . Female Fertility Advise females of reproductive potential who desire pregnancy that NSAIDs, including TREXIMET, may be associated with a reversible delay in ovulation [see Use in Specific Populations (8.3) ] . Heart Failure and Edema Advise patients to be alert for the symptoms of congestive heart failure including shortness of breath, unexplained weight gain, or edema and to contact their healthcare provider if such symptoms occur [see Warnings and Precautions (5.9) ] . Concomitant Use with Other Triptans or Ergot Medications Inform patients that use of TREXIMET within 24 hours of another triptan or an ergot-type medication (including dihydroergotamine or methysergide) is contraindicated [see Contraindications (4) , Drug Interactions (7.1) ] . Serotonin Syndrome Caution patients about the risk of serotonin syndrome with the use of TREXIMET or other triptans, particularly during concomitant use with SSRIs, SNRIs, TCAs, and MAO inhibitors [see Warnings and Precautions (5.11) , Drug Interactions (7.1) ] . Medication Overuse Headache Inform patients that use of acute migraine drugs for 10 or more days per month may lead to an exacerbation of headache and encourage patients to record headache frequency and drug use (e.g., by keeping a headache diary) [see Warnings and Precautions (5.10) ] . Ability to Perform Complex Tasks Treatment with TREXIMET may cause somnolence and dizziness; instruct patients to evaluate their ability to perform complex tasks after administration of TREXIMET [see Adverse Reactions (6.1) ] . Asthma Advise patients with preexisting asthma to seek immediate medical attention if their asthma worsens after taking TREXIMET. Patients with a history of aspirin-sensitive asthma should not take TREXIMET [see Contraindications (4) , Warnings and Precautions (5.18) ] . Avoid Concomitant Use of NSAIDs Inform patients that the concomitant use of TREXIMET with other NSAIDs or salicylates (e.g., diflunisal, salsalate) is not recommended due to the increased risk of gastrointestinal toxicity, and little or no increase in efficacy [see Warnings and Precautions (5.2) and Drug Interactions (7) ] .
