Zocor vs. Livalo

Are Zocor and Livalo the Same Thing?

Zocor (simvastatin) and Livalo (pitavastatin) are HMG-CoA reductase inhibitors ("statins") that lower lipids and cholesterol levels used in conjunction with lifestyle changes such as a low-fat, low cholesterol diet, and exercise to reduce the chances of cardiovascular disease and ischemic strokes in patients with elevated lipids and cholesterol.

Zocor is also used to treat heterozygous familial hypercholesterolemia (HeFH) in adolescents (males and females that are one-year post menarche, 10 to 17 years old).

Side effects of Zocor and Livalo that are similar include constipation, diarrhea, headache, joint pain, muscle pain, skin rash, or cold/flu symptoms such as stuffy nose, sneezing, or sore throat.

Side effects of Zocor that are different from Livalo include heartburn, gas, bloating, stomach pain, indigestion, nausea, sleep problems (insomnia), and mild memory problems or confusion.

Side effects of Livalo that are different from Zocor include back pain and pain in your arms and legs.

Both Zocor and Livalo may interact with alcohol, fibrates, medicines that contain niacin, and blood thinners.

This list is not complete and other drugs may interact with lovastatin. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.

What Drugs Interact With Livalo?

Livalo may interact with cyclosporine, erythromycin, rifampin, gemfibrozil, other fibrates, niacin, or warfarin.

How Should Zocor Be Taken?

The usual dosage range is 5 to 40 mg/day. In patients with CHD or at high risk of CHD, ZOCOR can be started simultaneously with diet. The recommended usual starting dose is 10 or 20 mg once a day in the evening. For patients at high risk for a CHD event due to existing CHD, diabetes, peripheral vessel disease, history of stroke or other cerebrovascular disease, the recommended starting dose is 40 mg/day. Lipid determinations should be performed after 4 weeks of therapy and periodically thereafter.

Restricted Dosing For 80 mg

Due to the increased risk of myopathy, including rhabdomyolysis, particularly during the first year of treatment, use of the 80-mg dose of ZOCOR should be restricted to patients who have been taking simvastatin 80 mg chronically (e.g., for 12 months or more) without evidence of muscle toxicity .

Patients who are currently tolerating the 80-mg dose of ZOCOR who need to be initiated on an interacting drug that is contraindicated or is associated with a dose cap for simvastatin should be switched to an alternative statin with less potential for the drug-drug interaction.

Due to the increased risk of myopathy, including rhabdomyolysis, associated with the 80-mg dose of ZOCOR, patients unable to achieve their LDL-C goal utilizing the 40-mg dose of ZOCOR should not be titrated to the 80-mg dose, but should be placed on alternative LDL-C-lowering treatment(s) that provides greater LDL-C lowering.

How Should Livalo Be Taken?

The dose range for Livalo is 1 to 4 mg orally once daily. The recommended starting dose is 2 mg and the maximum dose is 4 mg.
