Altocor

Altocor was a cholesterol-lowering medication that blocked the production of cholesterol (a type of fat) in the body.

Altocor reduced low-density lipoprotein (LDL) cholesterol and total cholesterol in the blood. Lowering your cholesterol can help prevent heart disease and hardening of the arteries, conditions that can lead to heart attack, stroke, and vascular disease. The brand name Altocor has been discontinued, but generic lovastatin is still available.

Altocor may also be used for other purposes not listed in this medication guide.

Take Altocor exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

Take Altocor with a full glass of water. Do not crush, chew, or break an extended-release tablet. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking or opening the pill would cause too much of the drug to be released at one time. Altocor is usually taken at bedtime or with an evening meal. If you take Altocor several times daily, take it with meals. Follow your doctor's instructions.

To be sure this medication is helping your condition, your blood will need to be tested on a regular basis. Your liver function may also need to be tested. Do not miss any scheduled appointments.

In rare cases, Altocor can cause a condition that results in the breakdown of skeletal muscle tissue. This condition can lead to kidney failure. Call your doctor at once if you have unexplained muscle pain or tenderness, muscle weakness, fever or flu symptoms, and dark colored urine.

Altocor is only part of a complete program of treatment that also includes diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.
