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.

Helps lower the risk of pancreas inflammation due to very high triglyceride levels
An alternative cholesterol medication for people who can't tolerate statins
Can lower the risk of serious heart events (e.g., heart attack) by 34% in certain middle-aged men
Available as a lower-cost generic
Not a first-choice option for lowering cholesterol
Can interact with statin medications, which many people take for high cholesterol
Should take 30 minutes before meals, which requires some planning
Not a good option for people who have liver, kidney, or gallbladder problems
Take gemfibrozil (Lopid) 30 minutes before breakfast and dinner every day. This will help the medication get absorbed into your body and work the best for you.
To get the most benefit from your gemfibrozil (Lopid) treatment, follow a diet that's low in fats, and eat more vegetables, fruits, and whole grains. Try to exercise 3 to 4 times a week, for a total of 150 minutes of exercise per week. Ask your provider if you need help figuring out your diet or exercise plan.
Make sure to keep up with all of your labs and follow-up appointments so you and your provider can track how well gemfibrozil (Lopid) is working for you. If your cholesterol and triglyceride levels don't improve in the first 3 months, gemfibrozil (Lopid) might not be the best medication for you. Your provider can discuss other treatment options with you.
If you're taking gemfibrozil (Lopid), let your provider know if you're starting another medication so they can check for possible interactions.
It's not known if gemfibrozil (Lopid) is safe to take while you're pregnant or breastfeeding. Let your provider know if this applies to you.
Gemfibrozil (Lopid) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Gemfibrozil (Lopid) can cause gallstones. Let your provider know right away if you experience stomach, back, or shoulder pain, nausea, vomiting, or yellowing of your eyes or skin. You shouldn't use gemfibrozil (Lopid) if you've had gallbladder problems before.
Gemfibrozil (Lopid) can interact with other medications. These interactions can be dangerous. If you're taking the blood thinner medication warfarin (Coumadin), let your provider or pharmacist know that you're also taking gemfibrozil (Lopid). Make sure to get your blood checks regularly. This is because gemfibrozil (Lopid) might raise the risk of bleeding in people taking warfarin (Coumadin).
Don't take gemfibrozil (Lopid) together with simvastatin (Zocor) since this combination can cause serious muscle damage and kidney failure. Your provider will switch you to a different statin if needed.
Always check with your provider or pharmacist before starting a new medication, vitamin, or supplement while you're taking gemfibrozil (Lopid).
Risk factors: Taking statin medications
Gemfibrozil (Lopid) might cause muscle damage. If severe enough, this can lead to kidney damage or even kidney failure. The risk is higher if you're also taking a statin medication. Talk to your provider if you develop sudden muscle pain, weakness, or dark-colored urine during treatment.
