Vascepa is a prescription medication used to treat high levels of triglycerides in the blood. The active ingredient in Vascepa is icosapent ethyl, which is a type of omega-3 fatty acid. The medication is classified as a pregnancy category C drug, which means that it may be harmful to an unborn baby and should only be used during pregnancy if the potential benefits outweigh the risks [2].

According to the drug label provided by the FDA, animal studies have shown that icosapent ethyl can cause fetal harm when administered during pregnancy. There are no adequate and well-controlled studies in pregnant women, and the medication should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus [2].

Drugs.com also states that there is a potential risk of fetal harm when using Vascepa during pregnancy. The website recommends that women who are pregnant or planning to become pregnant should talk to their doctor about the risks and benefits of using this medication [3].

It is important to note that Vascepa should only be used during pregnancy if it is deemed necessary by a healthcare provider. Women who are pregnant or planning to become pregnant should discuss the potential risks and benefits of using this medication with their doctor [2][3].
