Precautions while using fenofibric acid
It is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly to lower your cholesterol and triglyceride (fats) levels and to decide if you should continue to take it. Blood and urine tests may be needed to check for unwanted effects.
Check with your doctor right away if you have unexplained muscle pain, tenderness, or weakness, especially if you also have unusual tiredness or a fever. These could be symptoms of a serious muscle problem called myopathy.
Check with your doctor right away if you have dark-colored urine, diarrhea, a fever, muscle cramps or spasms, muscle pain or stiffness, or feel very tired or weak. These could be symptoms of a serious muscle problem called rhabdomyolysis, which can cause kidney problems.
Fenofibric acid may increase your risk of gallstones. Call your doctor right away if you have severe stomach pain with nausea and vomiting.
Pancreatitis may occur while you are using fenofibric acid. Tell your doctor right away if you have sudden and severe stomach pain, chills, constipation, nausea, vomiting, fever, or lightheadedness.
