Lovaza Side Effects
Burping, infections, and flu symptoms are the most common side effects reported with Lovaza. Side effects that are rare but possible include dry mouth, insomnia, and constipation. While most side effects of this product are mild, some are potentially serious and should be reported to your healthcare provider immediately, including chest pain and any signs of an allergic reaction (such as hives or breathing problems).
As with any medicine, side effects are possible with Lovaza® (omega-3-acid ethyl esters). However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Lovaza. Your healthcare provider can discuss a more complete list of Lovaza side effects with you.)
Lovaza has been studied thoroughly in clinical trials. In these studies, one group of people received the real medication, while another group was given a placebo (a "sugar pill" that does not contain any active ingredients). As a result, it is possible to see what side effects occurred, how often they appeared, and how they compared to the group who took the placebo.
In these studies, the most common side effects included:
- Burping -- in up to 4.9 percent of people
- Infections -- up to 4.4 percent
- Flu symptoms (such as fever or chills) -- up to 3.5 percent
- Indigestion or heartburn -- up to 3.1 percent
- Taste changes -- up to 2.7 percent
- Back pain -- up to 2.2 percent.
Lovaza often increases LDL cholesterol ("bad cholesterol"). Sometimes this increase is small; sometimes it is quite large. Your healthcare provider should monitor your LDL cholesterol while you are taking Lovaza.
