Does Lovaza (omega-3-acid ethyl esters) cause side effects?
Lovaza (omega-3-acid ethyl esters) is a fat-regulating (antilipemic) drug used in addition to diet to reduce triglyceride (TG, a fat-carrying particle in the blood) levels in adult patients with severe elevations in blood levels of TG (≥mg/dL).
TG is composed of three fatty acids as well as glycerol, and like cholesterol, comes from either the diet or the liver. High levels of TG in the blood are associated with conditions such as obesity, insulin resistance, and poorly controlled diabetes mellitus that contribute to the risk of hardening of the arteries (atherosclerosis) responsible for coronary artery disease (angina and heart attacks) and strokes.
The precise way in which Lovaza works is not clear; its proposed mechanism of action is by decreasing the amount of TG produced by the liver and increasing the removal of TG by the liver.
Serious side effects of Lovaza are rare and may include
- increased bleeding (symptoms include easy bleeding from cuts/bruising, black/tarry stools, and vomit that looks like coffee grounds).
- nonsteroidal anti-inflammatory drugs (NSAIDs),
- warfarin, and
- heparin, because their use with Lovaza may increase the risk of bleeding.
Some drugs may increase TG levels, so patients should tell their doctor or pharmacist of the following medications before using Lovaza:
Lovaza contains ethyl esters of omega-3 fatty acids which are obtained from the oil of several fish sources and should be used with caution in patients with known sensitivity or allergy to fish and/or shellfish.
There are no adequate and well-controlled studies of Lovaza in pregnant women. Lovaza should be used during pregnancy only if the potential benefit to the patient justifies the potential risk to the fetus.
What are the important side effects of Lovaza (omega-3-acid ethyl esters)?
Upset stomach, burping, and strange tastes in may occur. If these effects persist or worsen, patients should notify their doctor. They also should tell their doctors immediately if any of the following rare but serious side effects that suggest increased bleeding occur:

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% of subjects treated with Lovaza and at a greater rate than placebo 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 Lovaza
(n = 655)
(n = 370)
|a Trials included subjects with HTG and severe HTG.|
Additional adverse reactions from clinical trials are listed below:
Metabolic And Nutritional Disorders
Increased ALT and increased AST.
Pruritus and rash.
In addition to adverse reactions reported from clinical trials, the events described below have been identified during post-approval use of Lovaza. 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,
What drugs interact with Lovaza (omega-3-acid ethyl esters)?
Anticoagulants Or Other Drugs Affecting Coagulation
Some trials with omega-3-acids demonstrated prolongation of bleeding time. The prolongation of bleeding time reported in these trials has not exceeded normal limits and did not produce clinically significant bleeding episodes. Clinical trials have not been done to thoroughly examine the effect of Lovaza and concomitant anticoagulants. Patients receiving treatment with Lovaza and an anticoagulant or other drug affecting coagulation (e.g., anti-platelet agents) should be monitored periodically.
Does Lovaza (omega-3-acid ethyl esters) cause addiction or withdrawal symptoms?
Drug Abuse And Dependence
Lovaza does not have any known drug abuse or withdrawal effects.
Lovaza (omega-3-acid ethyl esters) is a fat-regulating (antilipemic) drug used in addition to diet to reduce triglyceride (TG, a fat-carrying particle in the blood) levels in adult patients with severe elevations in blood levels of TG (=mg/dL). Side effects of Lovaza include upset stomach, burping, and strange tastes. There are no adequate and well-controlled studies of Lovaza in pregnant women. Lovaza is excreted in human milk and caution should be exercised when administering Lovaza to breastfeeding women.

Lowering Triglycerides Naturally
Trigylcerides are fatty molecules that travel in the bloodstream. Excess sugar and fat can increase triglyceride levels. Triglycerides are also manufactured in the liver. The body uses triglycerides for energy, but excess triglycerides are a risk factor for heart attack, stroke, and obesity. Many lifestyle factors can influence triglyceride levels.
Cholesterol (Lowering Your Cholesterol)
High cholesterol and triglyceride levels increase the risk of cardiovascular disease. Getting your cholesterol and triglyceride levels in an optimal range will help protect your heart and blood vessels. Cholesterol management may include lifestyle interventions (diet and exercise) as well as medications to get your total cholesterol, LDL, HDL, and triglycerides in an optimal range.

HDL vs. LDL Cholesterol (Good and Bad)
HDL (high-density lipoprotein), or the "good" cholesterol, and LDL (low-density lipoprotein), or the "bad" cholesterol, are lipoproteins that carry cholesterol through the veins and arteries of the body. HDL and LDL combined, is your "total" blood cholesterol. The difference between the two are that high levels of the "good," or HDL cholesterol, may protect against narrowing of the blood vessels in the body, which protects you against heart attack, stroke, and other cardiovascular diseases. But high levels of LDL, or the "bad" cholesterol, may worsen the narrowing of the blood vessels in the body, which puts you at a greater risk of stroke, heart attack, and cardiovascular diseases, some of which are life threatening.Triglycerides are found in body fat and from the fats you eat.
High Cholesterol: Frequently Asked Questions
Cholesterol occurs naturally in the body. High blood cholesterol levels increase a person's risk of developing heart disease, heart attacks, strokes, TIAs, and more. In addition to medication (fibrates, statins, bile acid sequestrants, and niacin), lifestyle changes can be made to lower blood cholesterol levels
Low Cholesterol Diet
Cholesterol is naturally produced by the body, and is a building block for cell membranes and hormones. Low-density lipoprotein (LDL) cholesterol is the "bad" cholesterol, and high-density lipoprotein (HDL) cholesterol is the "good" cholesterol. High levels of LDL and low levels of HDL cholesterol put a person at risk for heart attack, stroke, transient ischemic attack (TIA or mini stroke), and peripheral artery disease. High cholesterol can be lowered by eating foods that lower cholesterol, for example, eat more high soluble fiber foods (oatmeal, oat bran, vegetables, and certain fruits), use olive oil, eat foods fortified with plant sterols and stanols, soy, nuts, and omega-3 fatty acids. Foods that raise LDL or bad cholesterol include foods high in saturated and trans fats, fatty meats, limit egg yolks, limit milk products, limit crackers, muffins, and snacks, and avoid unhealthy fast foods that are high in fat and sugar High cholesterol treatment includes lifestyle changes (diet and exercise), and medications such as statins, bile acid resins, and fibric acid derivatives.
