What It's For & How To Take
Simvastatin is used to decrease the production of cholesterol in your body. It does this by blocking an enzyme in the liver that is needed for cholesterol production. Simvastatin belongs to a class of medications known as the statins.
You may have extra cholesterol over time from either overproduction or an increased intake. Extra cholesterol leads to a buildup of cholesterol inside your blood vessels. The buildup of cholesterol on a blood vessel wall hardens and is known as plaque. The inside of your vessels become narrow, and blood flow may be decreased.
As your blood vessel narrows, you will have a decreased supply of blood to the rest of your body. This narrowing of your blood vessels is called atherosclerosis. Next, if the plaque ruptures, it can form a clot which may lead to either a stroke or a heart attack.
Simvastatin is usually taken once daily, in the evening, with or without food. Take your medication at the same time each day. If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
Your doctor will have you do some blood tests before you begin therapy and at regular intervals, after you have started your simvastatin. Do not miss your lab appointments. The blood work is done to make sure the medication is helping to lower the cholesterol and to see if your body is tolerating the medication.
