warnings and cautions

5 WARNINGS AND PRECAUTIONS In patients with hepatic impairment, monitor ALT and AST levels periodically during therapy. ( 5.1 ) Omega-3-acid ethyl esters capsules may increase levels of LDL. Monitor LDL levels periodically during therapy. ( 5.1 ) Use with caution in patients with known hypersensitivity to fish and/or shellfish. ( 5.2 ) There is a possible association between omega-3-acid ethyl esters and more frequent recurrences of symptomatic atrial fibrillation or flutter in patients with paroxysmal or persistent atrial fibrillation, particularly within the first months of initiating therapy. ( 5.3 ) 5.1 Monitoring: Laboratory Tests In patients with hepatic impairment, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels should be monitored periodically during therapy with omega-3-acid ethyl esters capsules. In some patients, increases in ALT levels without a concurrent increase in AST levels were observed. In some patients, omega-3-acid ethyl esters capsules increase LDL-C levels. LDL-C levels should be monitored periodically during therapy with omega-3-acid ethyl esters. Laboratory studies should be performed periodically to measure the patient's TG levels during therapy with omega-3-acid ethyl esters. 5.2 Fish Allergy Omega-3-acid ethyl esters capsules contains ethyl esters of omega-3 fatty acids (EPA and DHA) obtained from the oil of several fish sources. It is not known whether patients with allergies to fish and/or shellfish, are at increased risk of an allergic reaction to omega-3-acid ethyl esters capsules. Omega-3-acid ethyl esters capsules should be used with caution in patients with known hypersensitivity to fish and/or shellfish. 5.3 Recurrent Atrial Fibrillation (AF) or Flutter In a double-blind, placebo-controlled trial of 663 subjects with symptomatic paroxysmal AF (n = 542) or persistent AF (n = 121), recurrent AF or flutter was observed in subjects randomized to omega-3-acid ethyl esters who received 8 grams/day for 7 days and 4 grams/day thereafter for 23 weeks at a higher rate relative to placebo. Subjects in this trial had median baseline triglycerides of 127 mg/dL, had no substantial structural heart disease, were taking no anti-arrhythmic therapy (rate control permitted), and were in normal sinus rhythm at baseline. At 24 weeks, in the paroxysmal AF stratum, there were 129 (47%) first recurrent symptomatic AF or flutter events on placebo and 141 (53%) on omega-3-acid ethyl esters [primary endpoint, HR 1.19; 95% CI: 0.93, 1.35]. In the persistent AF stratum, there were 19 (35%) events on placebo and 34 (52%) events on omega-3-acid ethyl esters [HR 1.63; 95% CI: 0.91, 2.18]. For both strata combined, the HR was 1.25; 95% CI: 1.00, 1.40. Although the clinical significance of these results is uncertain, there is a possible association between omega-3-acid ethyl esters and more frequent recurrences of symptomatic atrial fibrillation or flutter in patients with paroxysmal or persistent atrial fibrillation, particularly within the first 2 to 3 months of initiating therapy. Omega-3-acid ethyl esters capsules are not indicated for the treatment of AF or flutter.

adverse reactions

6 ADVERSE REACTIONS The most common adverse reactions (incidence >3% and greater than placebo) were eructation, dyspepsia and taste perversion. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Par Pharmaceutical at 1-800-828-9393 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse reactions reported in at least 3% and at a greater rate than placebo for subjects treated with omega-3-acid ethyl esters capsules based on pooled data across 23 clinical trials are listed in Table 1. Table 1. Adverse Reactions Occurring at Incidence ≥3% and Greater than Placebo in Clinical Trials of Omega-3-Acid Ethyl Esters Capsules Adverse Reaction * Omega-3-Acid Ethyl Esters Capsules (N=655) Placebo (N=370) n % n % Eructation 29 4 5 1 Dyspepsia 22 3 6 2 Taste perversion 27 4 1 <1 * Trials included subjects with HTG and severe HTG. Additional adverse reactions from clinical trials are listed below: Digestive System: Constipation, gastrointestinal disorder and vomiting. Metabolic and Nutritional Disorders: Increased ALT and increased AST. Skin: Pruritus and rash. 6.2 Postmarketing Experience In addition to adverse reactions reported from clinical trials, the events described below have been identified during post-approval use of omega-3-acid ethyl esters capsules. Because these events are reported voluntarily from a population of unknown size, it is not possible to reliably estimate their frequency or to always establish a causal relationship to drug exposure. The following events have been reported: anaphylactic reaction, hemorrhagic diathesis.
