Key takeaways
Niacin ER (niacin) and Omega-3 acid ethyl esters (Lovaza) are both used to manage cholesterol and triglyceride levels, but they have different uses and side effects. Niacin ER is a form of vitamin B3 and is used to lower high cholesterol and triglycerides, as well as to reduce the risk of repeat heart attacks and slow plaque buildup in arteries. Common side effects include flushing and stomach upset. On the other hand, Omega-3 acid ethyl esters (Lovaza) is made up of two omega-3 fatty acids, EPA and DHA, and is specifically used to lower very high triglyceride levels. It is only available by prescription and can cause side effects like burping, upset stomach, and changes in taste. Unlike niacin ER, Lovaza is not known to cause flushing. Both medications are taken orally, but niacin ER is typically taken once daily at bedtime, while Lovaza can be taken once or twice daily with food. Additionally, Lovaza is not recommended for people with fish or shellfish allergies, whereas niacin ER has no such restriction.
