What are the risks and warnings for Gemfibrozil (Lopid)?
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.
Gallstones
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.
Interactions with other medications
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).
Muscle damage
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.
