Lovastatin (Mevacor, Altocor)

Mevacor and Altocor are the brand names. Lovastatin is the generic name. Lovastatin is the first statin (cholesterol-lowering drug) to be approved by the FDA. Like other statins, it reduces LDL cholesterol and triglyceride levels and raises the HDL cholesterol (the "good" cholesterol) level. Lovastatin is proven to reduce the risk of coronary artery disease events, such as heart attack or angina (chest pain).
 
For more information on statins and how they work, see Understanding Cholesterol-Lowering Medications, Medical Treatment.

Basic lovastatin medication information is as follows:

• Active ingredient: Lovastatin

• Dosage form: Tablet

• Strength: 10, 20, 40 mg

• FDA approval: 08/31/1987

• Company name: Merck

Lovastatin is a prescription medication that lowers the levels of "bad" cholesterol and triglycerides and raises the level of "good" cholesterol in the blood. LDL, or low-density lipoprotein, is referred to as the "bad" cholesterol. HDL, or high-density lipoprotein, is known as the "good" cholesterol. Lovastatin is for both adults and children older than 10 years whose cholesterol is not reduced enough with exercise and a low-fat diet.

Use of lovastatin in children is specifically indicated for an inherited condition, known as heterozygous familial hypercholesterolemia, that causes high cholesterol at a young age. Lovastatin is indicated for children aged 10-17 years with heterozygous familial hypercholesterolemia (girls in this age range must have already begun menstruating). When used along with diet, statins reduce total cholesterol, LDL, and apo B levels in children with heterozygous familial hypercholesterolemia. After an adequate trial of diet therapy, statins may be considered for treatment in children if one of the following findings is present:

• LDL-C remains greater than or equal to 190 mg/dL.

• LDL-C remains greater than or equal to 160 mg/dL and one of the following exists:
  • A positive family history of premature cardiovascular disease

  • Two or more other cardiovascular disease risk factors in the pediatric patient

You should not take lovastatin if you fit any of the following situations:
 

• You are pregnant, think you may be pregnant, or are planning to become pregnant. Lovastatin may harm your unborn baby. If you become pregnant, stop taking lovastatin and call your doctor right away.
  
  
• You are breastfeeding. Lovastatin can pass into your breast milk and may harm your baby.
  
  
• You have liver problems.
  
  
• You are allergic to lovastatin or any of its ingredients.

Lovastatin may cause serious, but rare, side effects, including the following:
 

• Muscle breakdown (myopathy): Muscle breakdown symptoms include widespread muscle aches, muscle tenderness, and generalized weakness. Rarely, widespread muscle breakdown, known as rhabdomyolysis, can occur, usually in people who are taking other drugs that interfere with the body’s ability to metabolize the statin and in people with advanced kidney problems. Therefore, it is extremely important that you inform your doctor about all the medications, herbal preparations, and dietary supplements you are currently taking. If you experience diffuse muscle pain and weakness or if your urine is brown (a possible sign of muscle breakdown), contact your doctor immediately and stop taking the statin medication.



• Liver problems: Lovastatin can cause liver problems. Your doctor may do a blood test to check your liver before you start taking lovastatin and while you are taking it.

Before starting lovastatin, tell your doctor about all of your medical conditions, including the following:
 

• If you have muscle aches or weakness



• If you drink more than 2 glasses of alcohol a day



• If you have diabetes



• If you have a thyroid problem



• If you have a kidney problem

Lovastatin and certain other medications can interact, causing serious side effects. Tell your doctor about any prescription and nonprescription medications you are taking, including the following:

• Vitamins



• Herbal supplements



• Medication for your immune system, such as drugs prescribed following organ transplantation



• Other cholesterol medications



• Medication for infections, such as erythromycin, clarithromycin, itraconazole, or ketoconazole



• Birth control



• Medication for heart failure



• Medication for HIV or AIDS



• Warfarin (Coumadin) (Other statins have been shown to increase warfarin effect and cause an increase in prothrombin time and bleeding.)

Avoid consuming large quantities of grapefruit juice (more than 1 quart per day) while you are taking lovastatin.

This is NOT a complete list of side effects reported with lovastatin. Your doctor, health care provider, or pharmacist can discuss with you a more complete list of side effects.
 
Statins are well tolerated, and serious side effects (liver problems and muscle soreness, pain, and weakness) are rare. The following more common side effects of lovastatin are usually mild and may go away:

• Headache



• Constipation



• Diarrhea



• Gas



• Upset stomach and stomach pain



• Rash



• Muscle and joint pain

Call your doctor if any of the following, more serious, side effects occur:

• Muscle weakness, tenderness, or pain



• Nausea, vomiting, and stomach pain



• Brown or dark urine



• Tiredness



• Yellowness of the skin and whites of the eyes



• Neuropathy (numbness and tingling) affecting the hands, arms, feet, and legs
