You should not use this medication if you are allergic to gemfibrozil or if you have gallbladder disease, liver disease, or severe kidney disease.
Gemfibrozil is only part of a complete program of treatment that also includes diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.
Avoid eating foods that are high in fat or cholesterol. Gemfibrozil will not be as effective in lowering your cholesterol if you do not follow a cholesterol-lowering diet plan.
To be sure this medication is helping your condition, your blood will need to be tested on a regular basis. Your kidney or liver function may also need to be tested. Do not miss any scheduled appointments.
Call your doctor at once if you have a serious side effect such as sharp pain in your upper stomach (especially after eating), jaundice (yellowing of your skin or eyes), blurred vision, eye pain, or seeing halos around lights, or pain or burning when you urinate.
