FAQs
Common questions about gemfibrozil
Below you’ll find answers to a few commonly asked questions about gemfibrozil.
What brand names are available for gemfibrozil?
Gemfibrozil is a generic version of the brand-name drug Lopid.
A generic drug is an exact copy of the active ingredient in a brand-name medication. (An active ingredient is what makes a drug work.) Generics are as safe and effective as the brand-name drug, and often cost less than the brand-name form.
To learn more about the brand-name form of gemfibrozil, talk with your doctor or pharmacist.
Is gemfibrozil similar to fenofibrate?
Yes, gemfibrozil has similarities to fenofibrate. Both are fibrate drugs used to lower certain cholesterol levels.
Specifically, gemfibrozil and fenofibrate are used for lowering triglyceride levels. But unlike fenofibrate, gemfibrozil is prescribed for reducing the risk of heart disease in certain people.
Fenofibrate is also used for lowering low-density lipoprotein (LDL) or “bad” cholesterol and increasing high-density lipoprotein (HDL) or “good” cholesterol.
If you’d like to learn more about how gemfibrozil and fenofibrate compare, talk with your doctor or pharmacist.
How does gemfibrozil work? And how long does it take to start working?
How gemfibrozil works isn’t completely understood. But it’s thought to work by decreasing the amount of triglycerides your liver makes. Taking gemfibrozil helps to lower triglyceride levels and reduce the risk of heart disease.
Gemfibrozil starts working after your first dose, but you likely won’t notice any changes. It may take several weeks for your triglyceride levels to decrease. Your doctor will give you blood tests to check your triglyceride levels during gemfibrozil treatment.
If you’d like to know more about how gemfibrozil works, talk with your doctor or pharmacist.
Is gemfibrozil a statin?
No, gemfibrozil isn’t a statin. Instead, gemfibrozil belongs to a group of cholesterol-lowering drugs called fibrates.
Like gemfibrozil, statins can be taken to lower triglyceride levels and reduce the risk of heart disease. Statins also have other uses.
Talk with your doctor or pharmacist to learn more about gemfibrozil and statins.
