Precautions

Drug information provided by: Merative, Micromedex®

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 triglycerides and 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 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.

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

This medicine may affect blood sugar levels. If you notice a change in the results of your blood or urine sugar tests or if you have any questions, check with your doctor.

This medicine may cause you to feel dizzy or faint, especially when you get up from a lying or sitting position. Getting up slowly may help. This effect should lessen after a week or two as your body gets used to the medicine. However, if the problem continues or gets worse, check with your doctor.

Do not stop taking niacin without first checking with your doctor. When you stop taking this medicine, your blood cholesterol levels may increase again. Your doctor may want you to follow a special diet to help prevent this from happening.

Before you have any medical tests, tell the medical doctor in charge that you are taking this medicine. The results of some tests may be affected by this medicine.

Do not take vitamins or other dietary supplements unless they have been discussed with your doctor. This especially includes vitamins or dietary supplements that contain niacin or similar ingredients.
