Key Points

The main differences between Lovaza and Vascepa are their FDA approved uses, dose schedule, side effects and price.

  • Both Lovaza and Vascepa are prescription oral medications used in addition to diet to help lower high triglyceride levels that can be dangerous for your heart.
  • However, Vascepa is also approved to be used with a statin in certain high risk groups with high triglycerides to lower the risk of outcomes like a heart attack or stroke.
  • Lovaza is not approved to be used with a statin for this purpose and it is not known if Lovaza prevents you from having a heart attack or stroke.

How do I take Lovaza or Vascepa?

Lovaza (generic name: omega-3-acid ethyl esters) and Vascepa (generic name: icosapent ethyl) both come as oral capsules you swallow. Lovaza can be taken once or twice a day, while Vascepa is taken twice a day. Both products are formulations of omega-3 fatty acids (from fish oil). Take your dose exactly as your doctor prescribes.

Both medicines are used in addition to a low-fat and low-cholesterol diet to lower triglycerides (hypertriglyceridemia) and are approved for use in adults only. An appropriate exercise program may need to be followed in addition to diet.

Before using Lovaza or Vascepa, tell your doctor if you are allergic to fish or shellfish.

Lovaza dose

  • The daily dose of Lovaza is 4 grams per day. You may take this dose as a single 4-gram dose (4 capsules); OR as two 2-gram doses (2 capsules given twice daily). Do not take more than 4 capsules of Lovaza per day.
  • Take Lovaza with food.
  • Take your Lovaza capsules whole. Do not break them open, crush, dissolve, or chew Lovaza.

Vascepa dose

  • The daily dose of Vascepa is 4 grams per day taken as either four 0.5 gram capsules twice daily; OR as two 1 gram capsules.
  • Take Vascepa with food.
  • Take your Vascepa capsules whole; do not break open, crush, dissolve, or chew Vascepa.

How do the side effects differ between Lovaza and Vascepa?

Lovaza side effects

The most common side effects that may occur with Lovaza are:

  • burping
  • upset stomach
  • a change in your sense of taste

Serious side effects with Lovaza have been reported and are:

  • changes in certain blood tests (liver; LDL (“bad”) cholesterol)
  • an increased risk of a heart rhythm problem in some high-risk people

Although serious bleeding was not reported in Lovaza clinical studies, if you take a blood thinner (for example, warfarin or aspirin) your doctor may need to monitor you for this effect.

Vascepa side effects

The most common side effects that may occur with Vascepa are:

  • muscle and joint pain.
  • swelling of the hands, legs, or feet.
  • constipation
  • mouth/throat pain
  • gout
  • heart rhythm problems (atrial fibrillation).

Vascepa may also cause serious side effects, such as :

  • heart rhythm problems (atrial fibrillation and atrial flutter). Tell your doctor if you get any symptoms of heart rhythm problems, such as a fast or irregular heart beat, lightheadedness, dizziness, shortness of breath, chest discomfort, or you faint.
  • possible allergic reactions if you are allergic to fish or shellfish
  • bleeding; risk may increase if you are also taking a blood thinner medicine (for example: warfarin or aspirin).

If you experience any serious side effects or an allergic reaction with either drug, contact your doctor or call for emergency medical help (911) immediately.

These are not all the possible side effects that can occur with Lovaza or Vascepa. Call your doctor for medical advice about side effects.
