Vascepa is a prescription medication used to treat high levels of triglycerides in the blood. It is a type of omega-3 fatty acid that comes from fish oil. According to the sources provided [1][2][3], Vascepa is taken orally, with or without food, as a capsule. The usual dose is 4 grams per day, which can be taken as two capsules twice a day or four capsules once a day. It is important to follow the doctor's instructions carefully when taking Vascepa, as the dosage may vary depending on the individual's medical condition and response to treatment. It is also important to note that Vascepa should not be taken by individuals who are allergic to fish or shellfish. If you miss a dose, you should take it as soon as you remember, but if it is close to the time for your next dose, you should skip the missed dose and continue with your regular dosing schedule. It is not recommended to take a double dose to make up for a missed one.
