Key takeaways
Gemfibrozil (Lopid) and Simvastatin (Zocor) are both medications used to manage cholesterol levels, but they belong to different classes and work in distinct ways. Gemfibrozil is a fibrate that helps break down fats in your body, lowering triglycerides and "bad" cholesterol (LDL) while raising "good" cholesterol (HDL). It is typically taken twice a day before meals. On the other hand, Simvastatin is a statin that blocks an enzyme in your liver that makes cholesterol, also lowering LDL and triglycerides while raising HDL. Simvastatin is usually taken once daily in the evening. While both medications can cause muscle pain, the risk is higher with Simvastatin, especially at higher doses. Additionally, Gemfibrozil should not be taken with statins like Simvastatin due to the increased risk of severe muscle damage. Simvastatin is available in both tablet and oral solution forms, whereas Gemfibrozil is only available as a tablet. Both medications require a prescription and are available in lower-cost generic forms.

Summary of Lopid vs. Zocor
Summary for Fibrate
Prescription only
Gemfibrozil (Lopid) is used as an add-on medication to diet to lower triglycerides (fats) and "bad" cholesterol (LDL). At the same time, this medication can help raise "good" cholesterol (HDL). The usual dosage is one tablet taken by mouth twice a day before meals. Common side effects of gemfibrozil (Lopid) include indigestion, stomach pain, and diarrhea. It has many interactions with other medications, including cholesterol-lowering medications called statins.
Summary for Statin
Prescription only
Simvastatin (Zocor) is a statin used to lower your cholesterol to help protect your heart and blood vessels from serious, and even life-threatening, medical problems, such as heart attack or stroke. Simvastatin (Zocor) isn't meant to lower cholesterol on its own. Instead, you should take it in addition to eating a healthy diet and having a regular exercise routine. To get the most out of the medication, it's best to take simvastatin (Zocor) nightly before going to sleep.
