Does Antara (fenofibrate) cause side effects?
Antara (fenofibrate) is a derivative of fibric acid used with dietary modifications to treat lipid disorders. It helps reduce levels of LDL-C, total cholesterol, triglycerides, and apolipoprotein B, and increase HDL-C. Antara is prescribed to patients with primary hypercholesterolemia or mixed dyslipidemia, and hypertriglyceridemia.
Common side effects of Antara include
Less common side effects of Antara include
- high blood pressure (hypertension),
- upset stomach,
- urinary tract infections (UTIs),
- muscle pain,
- kidney problems, and
- respiratory tract infections.
- Antara may increase the adverse effects of colchicine on muscle tissue.
- Cyclosporine may increase the toxic effects of Antara on the kidney while Antara may decrease blood levels of cyclosporine.
- Antara may increase the adverse effects associated with ezetimibe, HMG-CoA reductase inhibitors (statins), and sulfonylureas.
- Antara may increase the anticoagulation (blood-thinning) benefits of warfarin.

Clinical Trials Experience
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect rates observed in clinical practice.
- Adverse events reported by 2% or more of patients treated with fenofibrate and greater than placebo during double-blind, placebo-controlled trials, regardless of causality, are listed in Table 1.
- Adverse reactions led to discontinuation of treatment in 5.0% of patients treated with fenofibrate and in 3.0% treated with placebo.
- Increases in liver function tests were the most frequent events, causing discontinuation of fenofibrate treatment in 1.6% of patients in double-blind trials.
Table 1 : Adverse Reactions Reported by 2% or More of
Patients Treated with Fenofibrate and Greater than Placebo During the
Double-Blind, Placebo-Controlled Trials
|Body System Adverse Reaction||Fenofibrate*
|Body As A Whole|
|Abnormal Liver Function Tests||7.5%**||1.4%|
|Metabolic and Nutritional Disorders|
|Increased Creatine Phosphokinase||3.0%||1.4%|
|* Dosage equivalent to 130 mg
**Significantly different from placebo
The following adverse reactions have been identified during post approval use of fenofibrate. 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:
- renal failure,
- muscle spasms,
- acute renal failure,
- asthenia, and
- severely depressed HDL-cholesterol levels.
What drugs interact with Antara (fenofibrate)?
- Potentiation of coumarin-type anticoagulant effects has been observed with prolongation of the PT/INR.
- Caution should be exercised when coumarin anticoagulants are given in conjunction with Antara.
- The dosage of the anticoagulants should be reduced to maintain the PT/INR at the desired level to prevent bleeding complications.
- Frequent PT/INR determinations are advisable until it has been definitely determined that the PT/INR has stabilized.
- Immunosuppressants such as cyclosporine and tacrolimus can produce nephrotoxicity with decrease in creatinine clearance and because renal excretion is the primary elimination route of fibrate drugs including Antara, there is a risk that an interaction will lead to deterioration of renal function.
- The benefits and risks of using Antara with immunosuppressants and other potentially nephrotoxic agents should be carefully considered, and the lowest effective dose employed.
Bile-Acid Binding Resins
- Since bile acid binding resins may bind other drugs given concurrently, patients should take Antara at least 1 hour before or 4 to 6 hours after a bile acid binding resin to avoid impeding its absorption.
- Cases of myopathy, including rhabdomyolysis, have been reported with fenofibrates co-administered with colchicine, and caution should be exercised when prescribing fenofibrate with colchicine.
Antara (fenofibrate) is a derivative of fibric acid used with dietary modifications to treat lipid disorders. It helps reduce levels of LDL-C, total cholesterol, triglycerides, and apolipoprotein B, and increase HDL-C. Common side effects of Antara include abnormal liver tests including AST and ALT, and headache. Antara should be avoided during pregnancy unless the benefits justify the potential risk to the fetus. Antara should not be used in breastfeeding mothers.

What Are the Normal Cholesterol Levels According to Age?
Cholesterol is a waxy substance found in all the cells of the body. It is a type of fat that is produced by the liver. Cholesterol also comes from animal-derived foods, such as meat and dairy products.
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.
Lower Cholesterol Levels with Diet and Medications
High-density lipoprotein (HDL) cholesterol is considered "good" cholesterol because it actually works to keep the LDL or "bad" cholesterol from building up in your arteries. Foods like extra lean meats, skim milk, and vegetable-based "butter-like" substitutes may help decrease LDL levels in the bloodstream.
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.
What Are the Causes of High Cholesterol?
Your body naturally produces all the LDL (bad) cholesterol it needs. An unhealthy lifestyle – not enough exercise, too many unhealthy foods – makes your body produce more LDL cholesterol than it needs. This is the cause of high LDL cholesterol for most people.
What Are the Normal Cholesterol Levels By Age?
Cholesterol is a waxy substance found in all the cells of the body. It is a type of fat that is produced by the liver. Cholesterol also comes from animal-derived foods, such as meat and dairy products. It is an essential substance needed by the body for various purposes. Too much cholesterol, however, harms the body and increases the risk of various medical conditions, such as high blood pressure and heart diseases.
