Precautions

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 and to decide if you should continue to take it. Blood tests may be needed to check for unwanted effects.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.

Check with your doctor right away if you have dark urine, fever, muscle cramps or spasms, muscular pain, stiffness, tenderness, wasting or weakness, or unusual tiredness or weakness. These could be symptoms of a serious muscle problem called rhabdomyolysis and myopathy.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
