`
` --------------------------- INDICATIONS AND USAGE --------------------------­
`
`
` JUVISYNC (sitagliptin and simvastatin) is indicated in patients for
`
`
`
` whom treatment with both sitagliptin and simvastatin is appropriate. (1)
`
`
` Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor indicated as an
`
` adjunct to diet and exercise to improve glycemic control in adults with
`
`
`
`
`
`
`
` type 2 diabetes mellitus. (1.1)
` Simvastatin is an HMG-CoA reductase inhibitor (statin) indicated as an
`
`
`
` adjunctive therapy to diet to:
`
` • Reduce the risk of total mortality by reducing CHD deaths and
`
`
`reduce the risk of non-fatal myocardial infarction, stroke, and the
`
`
`
`
` need for revascularization procedures in patients at high risk of
`
`
` coronary events. (1.2)
`
`
` • Reduce elevated total-C, LDL-C, Apo B, TG and increase HDL-C in
`
` patients with primary hyperlipidemia (heterozygous familial and
`
`
`
`
` nonfamilial) and mixed dyslipidemia. (1.2)
` • Reduce elevated TG in patients with hypertriglyceridemia and
`
`
`
` reduce TG and VLDL-C
` in patients with primary dysbeta­
`
`
`
`
`
`
` lipoproteinemia. (1.2)
`
`
`
` • Reduce total-C and LDL-C in adult patients with homozygous
`
`
`familial hypercholesterolemia. (1.2)
`
` Important Limitations of Use:
` • JUVISYNC should not be used in patients with type 1 diabetes or
`
`
`
` for the treatment of diabetic ketoacidosis. (1.3)
` • JUVISYNC has not been studied in patients with a history of
`
`
`
`
` pancreatitis. (1.3, 5.1)
` • JUVISYNC has not been studied in Fredrickson types I and V
`
`
` dyslipidemias. (1.3)
`
` • Patients with severe renal impairment who require sitagliptin 25 mg
`
`
`
`
`
` should not use JUVISYNC due to the unavailability of this dosage
` strength for JUVISYNC. (1.3)

`
`
`
`
` -------------------------------CONTRAINDICATIONS ------------------------------­
`
`
`
`
` • History of a serious hypersensitivity reaction, such as anaphylaxis or
`
`
`
`
` angioedema, to any component of this medication. (4, 5.6, 6.2)
`
`
`
`
` • Concomitant administration of strong CYP3A4 inhibitors. (4, 5.2)
`
`
`
`
` • Concomitant administration of gemfibrozil, cyclosporine, or danazol.
`
`
`
`
`
` (4, 5.2)
` • Active liver disease, which may include unexplained persistent
`
`
`
`
`
`
`
`
` elevations in hepatic transaminase levels. (4, 5.3)
`
` • Women who are pregnant or may become pregnant. (4, 8.1)
`
` • Nursing mothers. (4, 8.3)
`
`
`
`
` ----------------------- WARNINGS AND PRECAUTIONS -----------------------­
`
`
`
` • There have been postmarketing reports of acute pancreatitis,
`
`
`
`
` including fatal and non-fatal hemorrhagic or necrotizing pancreatitis.
`
`
`
`
`
` If pancreatitis is suspected, promptly discontinue JUVISYNC. (5.1)
`
`
`
`
`
`
` • Skeletal muscle effects (e.g., myopathy and rhabdomyolysis): Risks
`
`
`
`
`
`
` increase with higher doses and concomitant use of certain
`
`
` medicines. Predisposing factors include advanced age (≥65),
`
` female gender, uncontrolled hypothyroidism, and renal impairment.
`
`
`
`
` (4, 5.2, 8.5)
`
`
`
`
` • Patients should be advised to report promptly any unexplained
`
`
`
` tenderness, or weakness.
`
`
` and/or persistent muscle pain,
`
` JUVISYNC therapy should be discontinued immediately if myopathy
`
`
` is diagnosed or suspected. See Drug Interaction table. (5.2)
`
`
`
`
` • Liver enzyme abnormalities: Persistent elevations
` in hepatic
`
`
`
`
`
` transaminase can occur. Check liver enzyme tests before initiating
`
`
` therapy and as clinically indicated thereafter. (5.3)
`
`
` • There have been postmarketing reports of acute renal failure,
`
`
`
` sometimes requiring dialysis, in patients treated with sitagliptin.
` Assessment of renal function is recommended prior to initiation of
`
`
`
`
` JUVISYNC and periodically thereafter. (5.4, 6.2)
`
`
` • There is an increased risk of hypoglycemia when JUVISYNC is
`
`
`
`
` added to an insulin secretagogue (e.g., sulfonylurea) or insulin
`
` therapy. Consider lowering the dose of the sulfonylurea or insulin to
`
`
`
`
`
`
` reduce the risk of hypoglycemia. (2.3, 5.5)
`
`
` • There have been postmarketing reports of serious allergic and
`
`
`
`
`
` hypersensitivity reactions in patients treated with sitagliptin such as
`anaphylaxis, angioedema, and exfoliative skin conditions including
`Stevens-Johnson syndrome.
`In such cases, promptly stop
`JUVISYNC, assess for other potential causes, institute appropriate
`monitoring and treatment, and initiate alternative treatment. (5.6,
`
`
`
`6.2)
`
`------------------------------ ADVERSE REACTIONS------------------------------­
`
`
`
`
`Most common adverse reactions (incidence ≥5%) with simvastatin are:
`
`
`
`
`upper respiratory infection, headache, abdominal pain, constipation,
`
`
`
`
`
`
`
`and nausea. Adverse reactions reported in ≥5% of patients treated
`
`
`
`
`
`with sitagliptin and more commonly than in patients treated with
`
`
`
`placebo are: upper respiratory tract infection, nasopharyngitis and
`
`
`
`headache. In the add-on to sulfonylurea and add-on to insulin studies,
`
`hypoglycemia was also more commonly reported in patients treated
`
`with sitagliptin compared to placebo. (6.1)

`
`1
`
`
`INDICATIONS AND USAGE
`
`JUVISYNC™ (sitagliptin and simvastatin) is indicated in patients for whom treatment with both
`
`
`sitagliptin and simvastatin is appropriate.
`
`1.1 Sitagliptin
`
`
`Sitagliptin is indicated as an adjunct to diet and exercise to improve glycemic control in adults with
`
`
`
`
`
`
`
`
`
`type 2 diabetes mellitus. [See Clinical Studies (14.1).]
`
`
`
`1.2 Simvastatin
`
`
`Therapy with lipid-altering agents should be only one component of multiple risk factor intervention in
`individuals at significantly increased risk for atherosclerotic vascular disease due to hypercholesterolemia.
`
`
`
`
`
`
`
`
`Drug therapy is indicated as an adjunct to diet when the response to a diet restricted in saturated fat and
`
`
`
`
`
`
`
`cholesterol and other nonpharmacologic measures alone has been inadequate. In patients with coronary
`
`
`
`
`
`
`
`
`heart disease (CHD) or at high risk of CHD, simvastatin can be started simultaneously with diet.
`
`
`
`

`
`Reference ID: 3359746
`

`
`
`

`

`
`Reductions in Risk of CHD Mortality and Cardiovascular Events
`
`In patients at high risk of coronary events because of existing coronary heart disease, diabetes,
`
`
`
`peripheral vessel disease, history of stroke or other cerebrovascular disease, simvastatin is indicated to:
`
`
`
`• Reduce the risk of total mortality by reducing CHD deaths.
`
`
`• Reduce the risk of non-fatal myocardial infarction and stroke.
`
`
`• Reduce the need for coronary and non-coronary revascularization procedures.
`
`
`Hyperlipidemia
`
`Simvastatin is indicated to:
`
`
`low-density lipoprotein cholesterol (LDL-C),
`• Reduce elevated total cholesterol (total-C),
`
`
`
`
`
`
`apolipoprotein B (Apo B), and triglycerides (TG), and to increase high-density lipoprotein
`
`cholesterol (HDL-C) in patients with primary hyperlipidemia (Fredrickson type IIa, heterozygous
`
`
`
`
`
`
`familial and nonfamilial) or mixed dyslipidemia (Fredrickson type IIb).
`
`
`
`
`• Reduce elevated TG in patients with hypertriglyceridemia (Fredrickson type lV hyperlipidemia).
`
`
`
`
`• Reduce elevated TG and VLDL-C in patients with primary dysbetalipoproteinemia (Fredrickson
`
`
`
`
`
`
`type lll hyperlipidemia).
`
`
`• Reduce total-C and LDL-C in patients with homozygous familial hypercholesterolemia as an
`
`
`
`adjunct to other lipid-lowering treatments (e.g., LDL apheresis) or if such treatments are
`
`
`
`
`
`
`
`
`unavailable.
`
`Important Limitations of Use
`
`JUVISYNC should not be used in patients with type 1 diabetes or for the treatment of diabetic
`
`
`
`
`ketoacidosis, as it would not be effective in these settings.
`
`JUVISYNC 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 for the development of pancreatitis while using
`
`
`
`
`
`
`
`
`
`
`JUVISYNC. [See Warnings and Precautions (5.1).]
`
`
`JUVISYNC has not been studied in conditions where the major abnormality is elevation of
`
`
`
`
`
`chylomicrons (i.e., hyperlipidemia Fredrickson types I and V).
`
`
`
`Because doses of JUVISYNC appropriate for patients with severe renal impairment (CrCl
`
`
`
`
`
`
`
`<30 mL/min, approximately corresponding to serum creatinine levels of >3.0 mg/dL in men and
`
`
`
`
`
`
`
`
`>2.5 mg/dL in women) or end-stage renal disease (ESRD) are not available in this combination product,
`
`
`
`
`
`JUVISYNC is not recommended in patients with severe renal impairment or ESRD.
`
`1.3
`
`
`
`
`DOSAGE AND ADMINISTRATION
`2
`
`
`2.1 Recommended Dosing
`
`
`
`
`
`
`
`
`
`
`
`The dosages for therapy with JUVISYNC are 100 mg/10 mg, 100 mg/20 mg, 100 mg/40 mg,
`
`
`
`
`
`
`
`
`
`50 mg/10 mg, 50 mg/20 mg, and 50 mg/40 mg (sitagliptin/simvastatin) once daily. JUVISYNC should be
`
`
`
`
`
`
`taken as a single daily dose in the evening. JUVISYNC must not be split or divided before swallowing.
`
`
`
`
`
`
`
`
`
`
`The recommended starting dose is 100 mg/40 mg per day. For patients already taking simvastatin
`
`
`
`
`
`
`
`
`
`
`
`
`(10, 20, or 40 mg daily) with or without sitagliptin 100 mg daily, JUVISYNC may be initiated at the dose of
`
`
`
`100 mg sitagliptin and the dose of simvastatin already being taken.
`
`After initiation or titration of JUVISYNC, lipid levels may be analyzed after 4 or more weeks and
`
`dosage adjusted, if needed.
`
`
`
`
`2.2 Patients with Renal Impairment
`
`
`
`
`
`
`
`
`
`JUVISYNC is not recommended in patients with severe renal impairment or ESRD. JUVISYNC can
`
`
`
`
`
`
`be used in patients with normal renal function or mild renal impairment (creatinine clearance [CrCl] greater
`
`
`
`
`
`
`
`
`
`
`
`than or equal to 50 mL/min, approximately corresponding to serum creatinine levels of less than or equal
`
`
`
`
`
`
`
`
`
`
`to 1.7 mg/dL in men and less than or equal to 1.5 mg/dL in women), without adjustment of the sitagliptin
`
`
`
`
`
`dose. Because simvastatin does not undergo significant renal excretion, modification of the dose of the
`
`
`simvastatin component should not be necessary in patients with mild renal impairment.
`
`
`
`
`
`
`
`
`
`For patients with moderate renal impairment (CrCl greater than or equal to 30 to less than
`
`
`
`50 mL/min, approximately corresponding to serum creatinine levels of greater than 1.7 to less than or
`
`
`equal to 3.0 mg/dL in men and greater than 1.5 to less than or equal to 2.5 mg/dL in women), the
`
`
`
`
`
`
`
`recommended starting dose of JUVISYNC is 50 mg/40 mg once daily. For patients with moderate renal
`
`
`
`impairment who are already taking simvastatin (10, 20, or 40 mg daily) with or without sitagliptin 50 mg
`
`
`
`Reference ID: 3359746
`
`
`3
`
`

`

`
`daily, JUVISYNC may be initiated at the dose of 50 mg sitagliptin and the dose of simvastatin already
`
`
`
`
`
`
`being taken.
`
`
`
`
`
`
`
`Assessment of renal function is recommended prior to initiation of JUVISYNC and periodically
`
`
`
`
`thereafter. Creatinine clearance can be estimated from serum creatinine using the Cockcroft-Gault
`
`
`formula. [See Warnings and Precautions (5.4); Clinical Pharmacology (12.3).] There have been
`
`
`
`
`
`
`postmarketing reports of worsening renal function in patients with renal impairment treated with sitagliptin,
`
`
`
`some of whom were prescribed inappropriate doses of sitagliptin.
`
`
`
`
`
`
`2.3 Concomitant Use with an Insulin Secretagogue (e.g., Sulfonylurea) or with Insulin
`
`
`
`W hen JUVISYNC is used in combination with an insulin secretagogue (e.g., sulfonylurea) or with
`
`
`
`
`
`
`
`
`
`
`insulin, a lower dose of the insulin secretagogue or insulin may be required to reduce the risk of
`
`hypoglycemia. [See Warnings and Precautions (5.5).]
`
`
`
`2.4 Coadministration with Other Drugs
`
`
`
`Patients taking Verapamil, Diltiazem, or Dronedarone
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`• The dose of simvastatin should not exceed 10 mg per day (100 mg/10 mg or 50 mg/10 mg per
`
`
`
`day of JUVISYNC) [see Warnings and Precautions (5.2); Drug Interactions (7.3); Clinical
`
`
`
`
`
`
`Pharmacology (12.3)].
`
`
`Patients taking Amiodarone, Amlodipine or Ranolazine
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`• The dose of simvastatin should not exceed 20 mg per day (100 mg/20 mg or 50 mg/20 mg per
`
`
`
`day of JUVISYNC) [see Warnings and Precautions (5.2); Drug Interactions (7.3); Clinical
`
`
`
`
`
`
`Pharmacology (12.3)].
`
`2.5 Patients with Homozygous Familial Hypercholesterolemia
`
`
`
`
`
`
`The recommended dosage is 100 mg/40 mg (for patients with normal or mildly impaired renal
`
`
`
`
`
`
`function) or 50 mg/40 mg (for patients with moderately impaired renal function) per day in the evening.
`
`
`
`
`
`
`
`JUVISYNC should be used as an adjunct to other lipid-lowering treatments (e.g., LDL apheresis) in these
`
`patients or if such treatments are unavailable.
`
`
`
`
`
`
`
`2.6 Chinese Patients Taking Lipid-Modifying Doses (greater than or equal to 1 g/day Niacin) of
`
`Niacin-Containing Products
`
`
`
`
`
`
`
`
`Because of an increased risk for myopathy in Chinese patients taking simvastatin 40 mg
`
`
`
`coadministered with lipid-modifying doses (greater than or equal to 1 g/day niacin) of niacin-containing
`
`
`
`
`
`products, caution should be used when treating Chinese patients with JUVISYNC 100 mg/40 mg or
`
`
`
`
`
`
`50 mg/40 mg per day coadministered with lipid-modifying doses of niacin-containing products. The cause
`
`
`
`
`
`
`
`
`
`
`
`
`
`of the increased risk of myopathy is not known. It is also unknown if the risk for myopathy with
`
`
`
`
`
`
`coadministration of JUVISYNC with lipid-modifying doses of niacin-containing products observed in
`
`
`Chinese patients applies to other Asian patients. [See Warnings and Precautions (5.2).]

`
`CONTRAINDICATIONS
`
`
`JUVISYNC is contraindicated in the following conditions:
`
`
`
`
`
`
`
`
`
`• History of a serious hypersensitivity reaction, such as anaphylaxis or angioedema, to any
`
`component of this medication. [See Warnings and Precautions (5.6); Adverse Reactions (6.2).]

`
`Reference ID: 3359746
`
`

`

`
`
`
`in hepatic
`
`• Concomitant administration of strong CYP3A4 inhibitors (e.g., itraconazole, ketoconazole,
`
`
`
`
`
`
`
`
`
`posaconazole, voriconazole, HIV protease inhibitors, boceprevir, telaprevir, erythromycin,
`
`clarithromycin, telithromycin and nefazodone) [see Warnings and Precautions (5.2)].
`
`
`
`
`
`• Concomitant administration of gemfibrozil, cyclosporine, or danazol [see Warnings and
`
`Precautions (5.2)].
`
`
`
`
`
`
`include unexplained persistent elevations
`liver disease, which may
`• Active
`
`transaminase levels [see Warnings and Precautions (5.3)].
`
`
`
`
`• W omen who are pregnant or may become pregnant. Serum cholesterol and triglycerides
`
`
`
`
`
`
`
`
`increase during normal pregnancy, and cholesterol or cholesterol derivatives are essential for
`
`
`
`fetal development. Because HMG-CoA reductase inhibitors (statins) decrease cholesterol
`
`
`
`
`
`
`
`
`synthesis and possibly the synthesis of other biologically active substances derived from
`
`
`
`
`
`
`cholesterol, simvastatin may cause fetal harm when administered to a pregnant woman.
`
`
`Atherosclerosis is a chronic process and the discontinuation of lipid-lowering drugs during
`
`
`pregnancy should have little impact on the outcome of long-term therapy of primary
`
`
`
`
`
`hypercholesterolemia. There are no adequate and well-controlled studies of use with JUVISYNC
`
`
`
`
`
`during pregnancy; however, in rare reports congenital anomalies were observed following
`
`
`
`
`
`
`
`intrauterine exposure to statins. In rat and rabbit animal reproduction studies, simvastatin
`
`revealed no evidence of teratogenicity. JUVISYNC should be administered to women of
`
`
`
`
`
`childbearing age only when such patients are highly unlikely to conceive. If the patient
`
`
`
`
`
`
`becomes pregnant while taking this drug, JUVISYNC should be discontinued immediately and
`
`
`
`
`the patient should be apprised of the potential hazard to the fetus [see Use in Specific
`
`
`Populations (8.1)].
`
`
`
`• Nursing mothers. Because statins have the potential for serious adverse reactions in nursing
`
`
`infants, women who require treatment with JUVISYNC should not breastfeed their infants. A
`
`
`
`small amount of another drug in the statin class passes into breast milk. It is not known whether
`
`
`simvastatin is excreted into human milk [see Use in Specific Populations (8.3)].
`
`
`
`5 WARNINGS AND PRECAUTIONS
`
`
`5.1 Pancreatitis
`
`There have been postmarketing reports of acute pancreatitis, including fatal and non-fatal
`
`
`
`
`
`
`
`
`hemorrhagic or necrotizing pancreatitis, in patients taking sitagliptin. After initiation of JUVISYNC, patients
`
`
`
`
`
`
`
`
`
`
`should be observed carefully for signs and symptoms of pancreatitis. If pancreatitis is suspected,
`
`
`
`
`
`
`JUVISYNC should promptly be discontinued and appropriate management should be initiated. It is
`
`
`
`unknown whether patients with a history of pancreatitis are at increased risk for the development of
`
`pancreatitis while using JUVISYNC. [See also Adverse Reactions (6.2).]
`
`
`
`5.2 Myopathy/Rhabdomyolysis
`
`
`
`
`Simvastatin occasionally causes myopathy manifested as muscle pain, tenderness or weakness
`
`
`with creatine kinase (CK) above ten times the upper limit of normal (ULN). Myopathy sometimes takes the
`
`
`
`
`
`
`
`
`
`form of rhabdomyolysis with or without acute renal failure secondary to myoglobinuria, and rare fatalities
`
`
`
`
`
`
`
`
`
`
`
`have occurred. The risk of myopathy is increased by high levels of statin activity in plasma. Predisposing
`
`
`
`
`
`
`
`factors for myopathy include advanced age (≥65 years), female gender, uncontrolled hypothyroidism, and
`
`
`renal impairment.
`
`
`
`
`
`The risk of myopathy, including rhabdomyolysis, is dose related. In a clinical trial database in
`
`
`
`
`which 41,413 patients were treated with simvastatin, 24,747 (approximately 60%) of whom were enrolled in
`
`
`
`
`
`
`
`
`
`
`
`studies with a median follow-up of at least 4 years, the incidence of myopathy was approximately 0.03%
`
`
`
`
`
`
`
`and 0.08% at 20 and 40 mg/day, respectively. The incidence of myopathy with 80 mg (0.61%) was
`
`
`
`
`disproportionately higher than that observed at the lower doses. In these trials, patients were carefully
`
`monitored and some interacting medicinal products were excluded.
`
`
`
`
`In a clinical trial in which 12,064 patients with a history of myocardial infarction were treated with
`
`
`
`
`
`simvastatin (mean follow-up 6.7 years), the incidence of myopathy (defined as unexplained muscle
`
`
`
`
`
`
`
`
`
`
`
`
`weakness or pain with a serum creatine kinase [CK] >10 times upper limit of normal [ULN]) in patients on
`
`
`
`
`
`20 mg/day was approximately 0.02%; in patients treated with 80 mg/day, the incidence was 0.9%. The
`
`
`
`
`
`incidence of rhabdomyolysis (defined as myopathy with a CK >40 times ULN) in patients on 20 mg/day
`
`
`
`was 0%; in patients on 80 mg/day, the incidence was approximately 0.4%. The incidence of myopathy,
`
`
`
`Reference ID: 3359746
`
`
`5
`
`

`

`
`including rhabdomyolysis, was highest during the first year and then notably decreased during the
`
`
`
`
`
`
`subsequent years of treatment. In this trial, patients were carefully monitored and some interacting
`
`
`
`
`
`medicinal products were excluded.
`
`There have been rare reports of immune-mediated necrotizing myopathy (IMNM), an autoimmune
`
`
`
`
`
`
`
`
`
`myopathy, associated with statin use. IMNM is characterized by: proximal muscle weakness and elevated
`
`serum creatine kinase, which persist despite discontinuation of statin treatment; muscle biopsy showing
`
`necrotizing myopathy without significant inflammation; improvement with immunosuppressive agents.
`
`
`
`All patients starting therapy with JUVISYNC, or whose dose of JUVISYNC is being increased,
`
`
`
`
`
`
`
`
`
`
`
`
`should be advised of the risk of myopathy, including rhabdomyolysis, and told to report promptly
`
`
`
`
`
`
`
`
`any unexplained muscle pain, tenderness or weakness particularly if accompanied by malaise or
`
`
`
`
`
`
`
`
`
`fever or if muscle signs and symptoms persist after discontinuing JUVISYNC. JUVISYNC therapy
`
`
`
`
`
`
`
`
`
`should be discontinued immediately if myopathy is diagnosed or suspected. In most cases, muscle
`
`
`
`
`
`
`symptoms and CK increases resolved when treatment was promptly discontinued. Periodic CK
`
`
`
`determinations may be considered in patients starting therapy with JUVISYNC or whose dose is being
`
`
`increased, but there is no assurance that such monitoring will prevent myopathy.
`
`
`
`Many of the patients who have developed rhabdomyolysis on therapy with simvastatin have had
`
`
`
`
`complicated medical histories, including renal impairment usually as a consequence of long-standing
`
`
`
`diabetes mellitus. Such patients merit closer monitoring. JUVISYNC therapy should be discontinued if
`
`
`
`
`
`
`
`
`markedly elevated CPK levels occur or myopathy is diagnosed or suspected. JUVISYNC therapy should
`
`
`
`
`
`also be temporarily withheld in any patient experiencing an acute or serious condition predisposing to the
`
`
`
`
`development of renal failure secondary to rhabdomyolysis, e.g., sepsis; hypotension; major surgery;
`
`trauma; severe metabolic, endocrine, or electrolyte disorders; or uncontrolled epilepsy.
`
`Drug Interactions
`
`
`
`
`
`
`The risk of myopathy and rhabdomyolysis is increased by high levels of statin activity in plasma.
`
`
`
`
`
`Simvastatin is metabolized by the cytochrome P450 isoform 3A4. Certain drugs which inhibit this metabolic
`
`pathway can raise the plasma levels of simvastatin and may increase the risk of myopathy. These include
`
`
`itraconazole, ketoconazole, posaconazole, and voriconazole, the macrolide antibiotics erythromycin and
`
`clarithromycin, the ketolide antibiotic telithromycin, HIV protease inhibitors, boceprevir, telaprevir, the
`
`
`
`
`
`
`antidepressant nefazodone, and grapefruit juice [see Clinical Pharmacology (12.3)]. Combination of these
`
`
`
`
`
`
`
`
`
`drugs with JUVISYNC is contraindicated. If short-term treatment with strong CYP3A4 inhibitors is
`
`
`
`unavoidable, therapy with JUVISYNC must be suspended during the course of treatment. [See
`
`Contraindications (4); Drug Interactions (7.1).]
`
`
`
`
`
`
`
`The combined use of JUVISYNC with gemfibrozil, cyclosporine, or danazol is contraindicated [see
`
`
`
`Contraindications (4); Drug Interactions (7.1, 7.2)].
`Caution should be used when prescribing other fibrates with JUVISYNC, as these agents can cause
`myopathy when given alone and the risk is increased when they are coadministered [see Drug Interactions
`
`
`(7.2)].
`
`
`
`
`Cases of myopathy, including rhabdomyolysis, have been reported with simvastatin coadministered
`
`with colchicine, and caution should be exercised when prescribing JUVISYNC with colchicine [see Drug
`
`Interactions (7.7)].
`
`
`The benefits of the combined use of JUVISYNC with the following drugs should be carefully weighed
`
`
`
`
`against the potential risks of combinations: amiodarone, dronedarone, verapamil, diltiazem, amlodipine,
`
`
`
`
`
`
`
`
`
`
`ranolazine and lipid-lowering drugs other than gemfibrozil (other fibrates or ≥1 g/day of niacin), [see Drug
`
`
`
`
`Interactions (7.2, 7.3, 7.4); Table 6 in Clinical Pharmacology (12.3)].
`
`Cases of myopathy, including rhabdomyolysis, have been observed with simvastatin coadministered
`
`
`
`
`with lipid-modifying doses (≥1 g/day niacin) of niacin-containing products. In an ongoing, double-blind,
`
`
`
`
`randomized cardiovascular outcomes trial, an independent safety monitoring committee identified that the
`
`
`
`incidence of myopathy is higher in Chinese compared with non-Chinese patients taking simvastatin 40 mg
`
`
`coadministered with lipid-modifying doses of a niacin-containing product. Caution should be used when
`
`
`
`
`
`
`
`
`
`treating Chinese patients with JUVISYNC 100 mg/40 mg or 50 mg/40 mg per day coadministered with
`
`
`
`
`lipid-modifying doses of niacin-containing products. It is unknown if the risk for myopathy with
`
`
`
`
`
`
`coadministration of JUVISYNC with lipid-modifying doses of niacin-containing products observed in
`
`
`Chinese patients applies to other Asian patients [see Drug Interactions (7.4)].
`
`
`Prescribing recommendations for interacting agents are summarized in Table 1 [see also Dosage
`
`and Administration (2.4); Drug Interactions (7.1, 7.2, 7.3); Clinical Pharmacology (12.3)].
