What are the most common side effects of Vascepa (icosapent ethyl)?
Vascepa’s most commonly reported side effects are typically gastrointestinal and related to bleeding risk. Patients most often report:
- Upset stomach, indigestion, or nausea
- Diarrhea
- Constipation
- Gas/bloating
- Headache
- Bruising or other minor bleeding (this is especially relevant if you also take blood thinners)
Can Vascepa cause bleeding or bruising?
Yes. Vascepa can increase bleeding tendency, so bruising or nosebleeds may happen more easily—particularly in people who take anticoagulants or antiplatelet medicines (like warfarin, apixaban, rivaroxaban, clopidogrel, or aspirin).
How common is nausea or stomach upset?
GI side effects are among the more frequently mentioned problems with Vascepa, so stomach discomfort (including nausea, indigestion, or diarrhea) is a common reason patients stop or reduce the dose.
What side effects should be taken seriously?
Stop and seek urgent medical care if you develop signs of significant bleeding (for example, heavy or persistent bleeding, black/tarry stools, vomiting blood, or blood in urine) or allergic symptoms (swelling of the face/lips, trouble breathing, widespread rash).
Does Vascepa interact with other meds that affect bleeding?
It can. The bleeding risk is higher when combined with other drugs that affect clotting (anticoagulants and antiplatelet drugs). If you’re on those medicines, your clinician may monitor you more closely.
What about elevated liver tests or other less-common effects?
Some patients may have lab changes (such as liver enzyme elevations) and other less common adverse effects depending on overall health and concurrent medications. If you’ve had abnormal liver tests, it’s important to follow your prescriber’s monitoring plan.
